Read This Before You Start

Five decisions shape the whole run.

Decision	Why it matters
Sweep each day before you leave it	Parasite Eve has many missable items — once you leave a day’s areas, you cannot return to them in the Normal Game. The worst offenders are the two Mod Permits: only 2 exist in the Normal Game (Day 2, from Baker at the NYPD) and they cannot be obtained later. See the full per-day missables table below.
Bank Junk all game	Every 300 Junk given to Wayne buys another special weapon, and the trade repeats — players routinely bank it ten or more times in a single run. Farm it from Central Park birds, Chinatown frogs, Museum lizards, and later the Chrysler Building floors 2–10.
Play with the EX Game in mind	The EX Game (New Game+) carries over your final weapon, armor, stored items and Bonus Points — and it is the only way into the Chrysler Building, home of the best gear, all rare Trading Cards, and the true final boss Truebred Eve, whose defeat unlocks the true ending. What you build in run one is what you climb with.
Respect the Chrysler point of no return	In the EX Game, once you go up to Eve’s chamber on the Museum 4th floor on Day 5, the Chrysler Building is locked for that entire playthrough. Do your Chrysler runs before that — the practical cut-off is right after the T-Rex.
Fight clean for Bonus Points	BP is earned per battle and taking damage reduces the award. It is spent on ATB speed, item capacity, or weapon/armor attributes, and anything unspent carries into the next round — so careful fighting now pays off across every future playthrough.

Story Synopsis

On December 24, 1997, NYPD rookie Aya Brea attends an opera at Carnegie Hall. During the performance, the lead actress Melissa Pearce causes the audience to burst into flames — everyone burns except Aya. Aya learns that a mutated strain of sentient mitochondria, dormant in Melissa’s kidney transplant, has awakened and seized control. Melissa transforms into Mitochondria Eve, a being that can manipulate cells to create fire and mutate organisms into Neo-Mitochondrial Creatures (NMCs).

Aya discovers she has her own mitochondrial powers — Parasite Energy — because she received a corneal transplant from her deceased sister Maya, whose mitochondria evolved symbiotically rather than parasitically. Over six days, Aya hunts Eve through NYC landmarks: Carnegie Hall, Central Park, the NYPD precinct, Chinatown, St. Francis Hospital, the sewers, the Museum of Natural History, and finally a naval vessel where she confronts the Ultimate Being — the offspring Eve created using engineered sperm from the sinister Dr. Hans Klamp.

100% Completion Roadmap

Full completion is a two-run structure: the story, then the tower.

Step	What to do
1 · Complete the Normal Game (Days 1–6)	Play through the entire story, collecting all missable items, Mod Permits, and Trading Cards available in each day. Defeat the Ultimate Being on Day 6.
2 · Start EX Game (New Game+)	After clearing the game once, the EX Game unlocks. This is a New Game+ that carries over your final weapon, armor, stored items, and Bonus Points (BP). Aya restarts at Level 1 but gains BP each day.
3 · Clear the Chrysler Building (77 floors)	Available only in the EX Game, this endurance dungeon contains the best weapons, armor, all Trading Cards, and 7 boss floors leading to the true final boss.
4 · Defeat Truebred Eve	The true final boss on Floor 77 of the Chrysler Building, taking the form of Aya’s deceased sister Maya. Defeating her unlocks the true ending.

Key Mechanics

Five systems carry the whole game.

Mechanic	How it works
ATB Combat	Battles occur in real-time without a separate battle screen. An Active Time Bar (ATB) fills to determine when Aya can act. Aya is bound within an invisible perimeter until all enemies are defeated or she escapes.
Parasite Energy (PE)	Aya’s mitochondrial powers, unlocked as she levels up. 15 abilities across Heal, Defense, and Attack types. PE slowly recharges during battle. The ultimate ability Liberate (Lv33) transforms Aya into a powerful mitochondrial creature.
Weapon Tuning	Use Tools and Super Tools to transfer parameters and effects between weapons. Mod Permits (from Baker) and Trading Cards (from Wayne) add customization slots to weapons.
Bonus Points (BP)	Earned on level up and distributed to ATB speed, item capacity, or weapon/armor attributes. In the EX Game, Aya receives set BP at the start of each day (800–3000 depending on day).
Junk Collection	Collect Junk from enemies and give 300 to Wayne for special weapons (DE50AE7 pistol, MAG rifle, P90 machine gun, M10B shotgun, HK40 grenade launcher, LAW80 rocket launcher).

Every Boss, with HP

Four Day 5 bosses — the Centipede, the Crab, the Triceratops and the Tyrannosaur are all fought in the normal game, not only in the Chrysler Building.

Day	Boss	Where	HP	Drop
1	Actress (Melissa, on stage)	Carnegie Hall stage	40	—

Chrysler Building

Each boss floor drops the elevator key for the next block — the keys are not lying around the building.

Floor	Boss	HP	Drop
10	Spiderwoman	1000	Chrysler Key 1
20	Alligator ×2	1100	Chrysler Key 2
30	Centipede — head / middle / tail	1600 / 500 / 800	Chrysler Key 3
40	Triceratops	2900	Chrysler Key 4
50	Cockroach — it gives birth to a second	4200	Chrysler Key 5
60	Crab — body / claws	6500 / 1500	Chrysler Key 6
70	Queen Bee, plus spawned bees	11300	Chrysler Key 7
77	Truebred Eve	40000	—

Floor 50: kill both cockroaches at the same time or the survivor births another. Floors 71–76 are empty — no chests, no fights, just the climb to Eve.

Junk, Wayne and the Chrysler Building

The 300-Junk trade repeats. Every 300 Junk buys another weapon, and players routinely bank it ten or more times in a single run.

Ask for a type and you get a fixed result: Pistol → DE50AE7 · Rifle → MAG · Machine Gun → P90 · Shotgun → M10B · Grenade Launcher → HK40 · Rocket Launcher → LAW80. Let Wayne choose and you get one of AK-47, PPsh41, SP1C, USP-TU — or Super Junk, which is worthless and cannot be traded back.

Where Junk comes from: Central Park birds, Chinatown frogs, Museum lizards, and in the Chrysler Building the crows and rats on floors 2–10 and the slimes from floor 61 up. The fastest farm is the floor 2–10 block, running the north–south corridors for packs of purple crows — roughly 30 Junk a trip.

The Chrysler Building has a point of no return. Once you go up to Eve’s chamber on the Museum 4th floor on Day 5 of the EX Game, the building is locked for that entire playthrough. Do your Chrysler runs before that — the practical cut-off is right after the T-Rex.

Trading Cards: the two normal ones are both on Day 3 — a garbage can near the Soho apartment, and a locker in the NYPD ground-floor changing room. Neither is in Chinatown. The 14 rare gun cards are in Chrysler storage rooms, and a rare card is worth two slot additions against a Mod Permit’s one. Eleven or twelve rare cards gets you the Tool Kit — and fourteen gets the Super Tool Kit, and the Kits carry into the next round.

Trophies and Achievements

There are none — on any platform. Parasite Eve was released on PSN as a PSOne Classic, a tier that never supported trophies, and it has not been added to the PS Plus Premium classics catalogue that retrofits them. It is not on the PlayStation Classic either. The only achievement set that exists is a community one on RetroAchievements — 64 achievements — which needs an emulator.

Bonus Points are the closest thing the game has to a completion score. You earn them per battle, and taking damage reduces the award; they are banked and paid out when you level. Clearing the normal game grants 3,000, the display caps at 99,999, and anything unspent carries into the next round.

Complete Story Walkthrough (Day-by-Day)

This walkthrough covers all 6 days of Parasite Eve, with key items, boss strategies, and missable warnings for each day.

Pick a chapter below, then use the Previous / Next buttons at the bottom of each chapter to move through the game.

DAY 1ResonanceLocation: Carnegie Hall | Date: December 24, 1997

Aya Brea, an NYPD rookie attending an opera at Carnegie Hall, watches the lead actress Melissa Pearce cause the audience to burst into flames. Aya is immune and confronts Melissa on stage, discovering her Parasite Energy powers. Melissa mutates into Eve and descends into the sewers.

Enter Carnegie Hall and watch the opera cutscene. The audience combusts — only Aya and Melissa survive.

Confront Melissa on stage. This is the first boss fight where Aya learns she can use Parasite Energy. Melissa attacks with targeted energy beams.

TIP: Fight clean. Bonus Points are earned per battle and taking damage reduces the award. Spend them on ATB speed, item capacity, or weapon and armor attributes; anything unspent carries into the next round.

After Melissa levitates away, head downstairs. Aya witnesses a rat mutate into an NMC (Neo-Mitochondrial Creature).

Find the diary backstage revealing Melissa overdosed on immunosuppressants after her kidney transplant, fearing she'd lose her lead role.

TIP: The Rehearse Key comes out of Melissa's diary. The Theater Key is on a burned body in the dressing rooms.

Confront Melissa in the Rehearsal Room, where she plays the piano. She mutates into Mitochondria Eve and escapes into the sewers.

Navigate the sewers, fighting mutant frogs and an alligator boss. Find your way back outside.

WARNING: The police cordon off Carnegie Hall the moment Day 1 ends and it never returns to the map. Sweep it before you leave: the M1911A1 is tucked in shadow near the sewer stairs, and there are chests behind the pillars and partitions.

Aya's partner Daniel Dollis escorts her away. She learns she is the sole survivor.

Bosses

BOSS Melissa (Stage)

Melissa attacks with targeted energy beams. Move constantly to dodge. Use Aya's default M84F pistol and attack when your ATB is full. This is a tutorial fight where you learn Parasite Energy — Aya's Heal 1 ability is available from the start.

BOSS Eve (Rehearsal Room)

Eve is more aggressive with energy attacks. Keep moving and attack with your best pistol between her attacks. Use Heal 1 (60 PE) to recover 30 HP when needed. She will eventually flee.

BOSS Alligator

A giant mutated alligator in the sewers. It has powerful melee attacks. Keep your distance, use the M1911A1 if available (higher rate of fire), and circle around it. It drops the Kv Vest 1 armor.

DAY 2FusionLocations: NYPD, Central Park | Date: December 25, 1997 (Christmas)

The police attempt to suppress Eve's existence. At a press conference, Captain Baker covers up the Carnegie Hall incident, but Aya reveals the truth. Aya and Daniel visit Dr. Klamp at the museum, then pursue Eve to Central Park where she turns the audience at Delacorte Theater into an orange slime mass.

Attend the press conference at NYPD. Aya reveals the truth about Eve despite Baker's objections.

Collect both Mod Permits from Baker at the NYPD. These are critical — use both with Torres before Day 3, because he dies on Day 3.

TIP: Each Mod Permit adds one slot to a weapon or armor when you hand it to Torres. These are the only two in the Normal Game.

Visit Dr. Hans Klamp at the American Museum of Natural History. He explains mitochondria and Mitochondrial Eve. When Aya mentions 'Eve,' Klamp becomes surprised and stops talking.

Pursue Eve to Central Park. Daniel stays outside due to the danger of combustion.

Explore Central Park. Find the Zoo Key and various equipment in the office and forest areas.

WARNING: Central Park and the zoo are a one-visit area. Once the confrontation at the amphitheatre ends the day, the area closes, so empty the office and the forest first. The Zoo Key is in a drawer in the zoo office.

TIP: The birds in the park drop Junk in packs. Every 300 Junk you give Wayne buys one special weapon, so start banking it now.

Reach the Delacorte Theater. Eve turns the audience into an orange slimy mass. Battle Eve during an immolated horse ride. Aya is knocked unconscious.

Daniel discovers his son Ben escaped being turned to slime, but his ex-wife Lorraine was not so fortunate. Manhattan is evacuated. Maeda finds Aya and takes her to a vacated apartment.

Large worm-like NMCs in Central Park. They emerge from the ground and attack with body slams. Use rifles or machine guns for rapid fire. Keep moving to avoid being surrounded.

BOSS Eve (Horse Ride)

Eve rides an immolated horse at the Delacorte Theater. She attacks with energy projectiles while moving. Time your attacks between her barrages. The fight ends when Aya is knocked unconscious — you don't need to defeat her here.

DAY 3SelectionLocations: Soho, NYPD | Date: December 26, 1997

Aya awakens in a Soho apartment with Daniel and Maeda. Maeda reveals Eve's origins — a scientist's wife's mitochondria took over her body. Maeda believes Eve is trying to give birth to an 'Ultimate Being.' The three visit Klamp again, then rush to the police station which has been attacked by Eve.

Wake up in the Soho apartment. Maeda explains the origins of Eve and the Ultimate Being theory.

Visit the Soho gun store for weapons and armor. Find Trading Card 1 in a garbage can near the Soho apartment.

WARNING: Soho is a one-visit area. Empty both the gun store and the pharmacy, and take the Trading Card from the rubbish outside. Speak to Cathy, Warner and Wayne before you leave, because the day ends on a forced fight.

Visit Dr. Klamp again. He tells Aya that the nuclei in her cells are fighting Eve's mitochondria. He asks questions then dismisses them.

Return to the NYPD precinct, which has been attacked by Eve. Save Ben and Baker from the mutated police dog Sheeva. Later, a Dogman kills Torres Owens in the Weapons Department.

Search the NYPD ground-floor changing room locker. Find Trading Card 2.

Pick up the M92F pistol from Wayne at the NYPD.

TIP: Wayne also trades Junk for weapons. At 300 Junk he builds one top-tier weapon of the class you name, the earliest being Day 4. Ask for a type (Pistol DE50AE7, Rifle MAG, Machine Gun P90, Shotgun M10B, Grenade Launcher HK40, Rocket Launcher LAW80) and never let him choose — that rolls a lesser weapon or wastes the 300 Junk. Your total is cumulative, so 600 buys a second weapon.

Key Items

Trading Card 2

Normal Trading Card. In a locker in the NYPD ground-floor changing room. Give to Wayne for weapon mods. MISSABLE

Bosses

BOSS Sheeva / Kerberos (Mutated Police Dog)

A mutated police dog with a barrier that makes it difficult to damage. Use offense boosters and items to break through its defenses. Physical attacks alone won't suffice — use Parasite Energy (Energy Shot once you reach Lv15) and offensive items. It drops the M9-2 pistol. A Dogman later kills Torres Owens in the Weapons Department.

DAY 4ConceptionLocation: St. Francis Hospital | Date: December 27, 1997

Aya and Maeda head to St. Francis Hospital, where Maeda believes Eve will try to obtain sperm for the Ultimate Being. The hospital is overrun with NMCs. Eve has already taken the sperm. Aya discovers her mother's and sister's medical records.

Enter St. Francis Hospital, overrun with NMCs. Try to save remaining staff and patients.

WARNING: The hospital is a one-visit area. A hidden box behind the overturned cabinet can be searched repeatedly for Trading Cards, but only while you are in that room the first time. Empty your inventory before you open it, because leaving the room closes it for good.

Explore the basement. Eve traps Aya by cutting off power to the elevator.

Find Fuse 1 on top of the bookcases in the library room, Fuse 2 on a medicine box in the autopsy area and Fuse 3 in the bottom-right corner of the dark room. Insert them in the fuse box, reconnect the wires and switch the power on.

TIP: At the reservoir pumps, set Master Power ON, run Pump 1, run Pump 2, then set Master Power OFF and head north (the order of the two pumps does not matter). This drains the reservoir and lets the Giant Slime out. The Slime respawns every time you re-enter its room and a Club-type weapon can steal Defense +1 from it, so it is the best place to farm.

Explore the upper floors. Discover Aya's mother's and sister's medical records.

TIP: Past the green keycard doors, turn the wheels on the pipes in the bottom right to cut the liquid nitrogen feed to the sperm bank.

Reach the rooftop. Eve telepathically kills fighter jet pilots. She has already taken the sperm and flees.

Defeat the Spiderwoman boss on the rooftop.

Aya jumps off the roof before it is struck by the crashing jets. Reunite with Daniel and Maeda.

Bosses

BOSS Spiderwoman (Rooftop)

A giant spider-like NMC on the hospital rooftop. It attacks with web projectiles that can immobilize Aya. Dodge the web attacks by moving constantly — strafe left and right. Use your best rifle or machine gun for sustained fire. The G3A3 (found on the 13th floor) is excellent here. Watch out for its lunging attack when you get too close.

DAY 5EvolutionLocations: Sewers, Chinatown, Subway, Warehouse, Museum, Liberty Island | Date: December 28, 1997

Day 5 is the longest day, spanning three areas. Aya investigates the sewers, a warehouse, and the Museum of Natural History. She discovers Klamp engineered sperm for Eve, fights reanimated dinosaurs, and confronts a pregnant Eve at Liberty Island.

Part 1: Sewers

Enter the sewers following evidence of mutant slime in the water supply.

TIP: Maeda hands you a charm on the surface before you go down. The sewers use the same pump mechanic as the hospital, plus a ladder-and-drain route through to the subway tracks. The frogs here drop Junk.

Use the control panel to pump orange slime away from the city's water reservoir, preventing contamination.

Navigate the sewer labyrinth, collecting the Pump Key, Warehouse Key, and Gate Key. Fight the Centipede boss in the Subway.

Find the Cr Protector armor in the sewer labyrinth (easy to miss).

Pump Key

Pumping station key. Sewers. KEY ITEM

Warehouse Key

Port storage key. Sewers. KEY ITEM

Gate Key

Subway gate key. Sewers. KEY ITEM

M203-2

M870

Cr Protector

Ceramics armor (DE 39+2, PE 41+2, CR 25+1, 2 slots). Increases Max HP; AT recharges slower. Chinatown sewer labyrinth. MISSABLE

Pump Orange Slime from Water Supply

The orange mass of people from Central Park has entered the city water supply. Use the control panel in the sewer pumping station to pump the slime away, preventing it from infecting the city's water reservoir. This is a critical story puzzle.

Part 2: Warehouse

Enter the Pier No. 3 warehouse using the Warehouse Key from the sewers. Fight the Crab boss in the warehouse basement.

WARNING: The warehouse is optional and open on Day 5 only. Skip it and you lose the AT4 rocket launcher, the PPK, an M203-2, several armor pieces and a Defense +2 for that run. The Tool in the north-west corner sits behind venting steam — grab it in the gap when the steam draws back into the pipe.

Collect armor and equipment, including the Sp Protector and Cm Protector.

B Protector

Bio armor (DE 32+1, PE 38, CR 22+1, 2 slots). Resist Stiffness. Subway.

M79-2

Grenade launcher (ATK 45+1, Range 68, 4+2 bullets, 4 slots). Adds Acid effect. Subway Station.

Sp Protector

Spectra armor (DE 38+1, PE 23, CR 26, 3 slots). Warehouse.

Cm Protector

Chemical armor (DE 36+1, PE 48, CR 29+2, 3 slots). Uses Medicine when HP is low. Warehouse.

Mayoke

Helpful good luck charm. Found during Day 5. KEY ITEM

Part 3: Museum of Natural History

Visit Dr. Klamp at the museum. Discover he has engineered special sperm for Eve to create the Ultimate Being. Aya tries to arrest him but he bursts into flames and dies after Daniel shoves him.

Fight the reanimated dinosaurs in the museum exhibits, including the Triceratops on the 3rd floor and the Tyrannosaur on the 1st floor.

TIP: Answer every interactive exhibit pedestal in the museum; each correct answer dispenses an item (medicines, ammo or a Revive). The answers: 9 animals in the picture; Mitochondria appeared inside the first organism; it fed on nitrogen oxides produced by volcanoes; ATP is about 200,000 volts per cubic centimetre; taking mitochondria in led to ageing; Mitochondria Eve is an African female; oxygen rose 25 million years ago because of photosynthesis by bacteria. The museum lizards drop Junk.

Find a pregnant Eve in another part of the museum. The slime mass forms a giant monster that carries Eve away in its protective shield. Do not take the hidden elevator in the Museum security office up to Eve's chamber on the 4th floor until you are done with the Chrysler Building in an EX Game; it locks the city and the Chrysler Building for that playthrough.

POINT OF NO RETURN: The hidden elevator is in the security office — walk off the right edge of the screen to find it. Taking it up to Eve ends Manhattan permanently: no city map, no shops, no police storage, and no Chrysler Building for the rest of that playthrough. In an EX Game this is where you forfeit the true ending, so finish every Chrysler run and storage trip first. The 4th-floor room holds the M500 and the B Jacket 1.

The military asks Aya to attack Eve from a helicopter (she's the only one who can approach without combusting). Attack from the chopper, then finish the fight on Liberty Island beside the wrecked Statue of Liberty.

Bosses

BOSS Slime Monster

The orange slime mass from Central Park has become a giant monster. It surrounds Eve in a protective shield. You fight it from a helicopter first — use your best weapons to damage it. It has multiple attack patterns including sweeping slams and projectile slime.

BOSS Eve (Liberty Island)

The final confrontation with Eve beside the wrecked Statue of Liberty. Eve has multiple phases. Attack from the helicopter first, then fight her personally on the ground. She uses powerful energy attacks — use Barrier (if unlocked at Lv13) and Haste (Lv20) to survive. Use Energy Shot or Liberate for burst damage. Eve finally succumbs and dies.

DAY 6LiberationLocation: Naval Vessel | Date: December 29, 1997

Aya rests on a naval vessel. Maeda and Daniel are relieved she is safe. However, the Ultimate Being is born and attacks the surrounding ships. Aya must defeat it and escape before the ship explodes.

Before you leave for the docks, have Wayne engrave Aya's name on one weapon and one armor and put anything worth keeping into police storage. This is the last chance. Rest on the naval vessel. Receive Maeda's Gun and DNA Bullets — the only weapons that can damage the Ultimate Being.

WARNING: The engraved weapon and armor, everything in police storage, your Bonus Points and your running Junk total carry into the EX Game; Aya's level resets to 1 and plot items (keys and Maeda's charms) are stripped. Without an engraved pair you start the EX Game with nothing. If you already carry engraved gear from an earlier run and engrave new items, the old pair is lost when the EX Game starts — park the old customs in police storage first.

The Ultimate Being is born and attacks. Battle it across multiple forms as it evolves during the fight.

Set the vessel's boiler pressure dangerously high to destroy the ship with the Ultimate Being onboard.

Escape the ship before it explodes. Aya jumps off and the cruiser explodes, killing the Ultimate Being.

TIP: Let the credits run all the way out and save the clear data. That grants 3,000 Bonus Points and puts EX GAME above New Game on the title screen.

Key Items

Maeda's Gun

Pistol (ATK 1, Range 60, 15 bullets, 1 slot). Given by Maeda on Day 6. Cannot be removed from inventory. Required to damage the Ultimate Being. KEY ITEM

DNA Bullets

Maeda's special bullets for Maeda's Gun. Given near endgame. Required to damage the Ultimate Being. KEY ITEM

Bosses

BOSS Ultimate Being (4 Forms)

The Ultimate Being evolves through multiple forms during the fight, fusing with objects on the vessel. You MUST use Maeda's Gun with DNA Bullets — normal weapons cannot damage it. The being's mitochondria cause it to evolve at an alarming rate. Each form is stronger than the last. Use Liberate (if at Lv33) for massive burst damage. After weakening it, set the boiler pressure high and escape before the ship explodes. The cruiser explodes, killing the Ultimate Being.

TIP: After the credits roll, the EX Game (New Game+) unlocks, granting access to the Chrysler Building and the true final boss.

Weapons Guide

Parasite Eve features 60+ weapons across 7 categories. Each weapon has stats for Attack, Range, Bullets, Slots, Special Effects, and Rate of Fire. Weapons can be customized using Tools, Super Tools, and Trading Cards to transfer parameters between them. The best weapons are obtained by giving Wayne 300 Junk.

TIP: Use Super Tools (not regular Tools) to transfer parameters without destroying the source weapon. Super Tool Kits are obtained from Wayne by collecting Trading Cards in the Chrysler Building.

Special Junk Weapons (300 Junk Rewards)

Collect 300 Junk items from defeated enemies and give them to Wayne. You can either ask for a specific weapon type, or leave the decision to Wayne (random result). When you leave it to Wayne, you may get a different weapon than expected, plus Super Junk and Duper Junk byproducts.

NOTE: You can only get ONE weapon from Wayne per playthrough for each 300 Junk. To get all 6 special weapons, you need multiple EX Game playthroughs.

DE50AE7 (Pistol, ATK 123+2) — ask for pistol
MAG (Rifle, ATK 151+1) — ask for rifle
P90 (Machine Gun, ATK 122) — ask for machine gun
M10B (Shotgun, ATK 120+1) — ask for shotgun
HK40 (Grenade Launcher, ATK 115+1) — ask for grenade launcher
LAW80 (Rocket Launcher, ATK 200+20) — ask for rocket launcher

If you leave the decision to Wayne, you might randomly receive USP-TU (pistol, ATK 115+1), SP1C (pistol, ATK 118+2), AK-47 (rifle, ATK 155), or PPsh41 (machine gun, ATK 78+2) instead.

Parasite Energy Abilities

Parasite Energy (PE) is Aya's mitochondrial power system. There are 15 abilities across three types: Heal (recovery), Defense (buffs/debuffs), and Attack (offensive). PE slowly recharges during battle. Abilities unlock as Aya levels up, with the ultimate ability Liberate available at Level 33.

Name	Type	MP/PE Cost	Effect	Unlocked

Preraise	Heal	Very Large (1000 PE)	Aya receives HP when her HP reaches 0	Lv 30

Liberate	Attack	All PE	Aya transforms into a powerful mitochondrial creature. Always does at least 1200+ damage (split between targets). Leaves Aya dizzy afterward.	Lv 33

TIP: Liberate (Lv 33) is Aya's best attack. It transforms her into a blue-green mitochondrial creature with wing-like appendages, dealing massive combo damage. Its only drawback is emptying her PE meter and leaving her dizzy after reverting — be careful in boss battles.

Enemies & Bosses

Parasite Eve features a variety of Neo-Mitochondrial Creatures (NMCs) — animals and organisms mutated by Eve's mitochondria. This page covers common NMC types and detailed boss strategies for all story and Chrysler Building bosses.

Common NMC Types

NMCs are encountered via 'hot spots' — the screen flashes, a heartbeat sounds, and enemies materialize. Common NMC types include:

Rats (including Golden Rats in Chrysler Building)
Frogs (mutated, found in sewers)
Alligators (sewers, boss variant in Chrysler Building)
Bats (flying enemies in dark areas)
Spiders (including Spiderwoman boss)
Scorpions (desert/exhibit areas)
Dogs / Dogmen (mutated police dogs, including Sheeva/Kerberos boss)
Monkeys / Flymen (mutated primates)
Parrots (mutated birds)
Snakes (various areas)
Cats (mutated felines)
Bears (large dangerous NMCs)
Chameleons (can turn invisible)
Crows (flying enemies)
Moles (underground enemies)
Pterodactyls (museum dinosaur exhibits)
Armadillos (armored enemies)
Dinosaurs: Troodon, T-Rex, Triceratops (museum exhibits, reanimated)
Squirrels (Chrysler Building only)
Cockroaches (Chrysler Building, including boss variant)
Bees (Chrysler Building, including Queen Bee boss)
Crabs (Pier No. 3 warehouse on Day 5; Giant Crab boss on Chrysler Floor 60)
Centipedes (Subway on Day 5; Chrysler Floor 30 boss)
Treasurebox (mimic-type enemy)

Story Boss Strategies

Day 1: Resonance

BOSS Melissa (Stage Fight)

The first boss encounter at Carnegie Hall. Melissa attacks with targeted energy beams. Move constantly to dodge — strafe left and right between her attacks. Use Aya's default M84F pistol and attack when the ATB is full. This is where Aya learns she can use Parasite Energy — the Heal 1 ability (60 PE, restores 30 HP) unlocks here. Melissa will eventually levitate away after taking enough damage.

BOSS Eve (Sewers)

Eve is more aggressive than Melissa, using powerful energy attacks in the Carnegie Hall sewers. Keep moving and attack with your best available pistol (M1911A1 if found) between her barrages. Use Heal 1 to recover HP when needed. Eve will flee after sufficient damage.

BOSS Alligator

A giant mutated alligator encountered in the Carnegie Hall sewers. It has powerful melee attacks and a lunging bite. Keep your distance and circle around it. Use the M1911A1 (higher rate of fire) if available. The Alligator drops the Kv Vest 1 armor (DE 19+1).

Day 2: Fusion

BOSS Giant Worms

Large worm-like NMCs encountered in Central Park. They emerge from the ground and attack with body slams. Use rifles (M16A1 from Torres) or machine guns for rapid fire. Keep moving to avoid being surrounded by multiple worms.

BOSS Eve (Horse Ride, Central Park)

Eve rides an immolated horse at the Delacorte Theater, attacking with energy projectiles while in motion. Time your attacks between her barrages. This is a scripted encounter — you don't need to fully defeat Eve. The fight ends when Aya is knocked unconscious.

Day 3: Selection

BOSS Sheeva / Kerberos (Mutated Police Dog)

A mutated police dog with a protective barrier that makes it highly resistant to normal physical attacks. Use offense boosters (Offense +1/+2/+3) and offensive items to break through its defenses. Parasite Energy attacks (Energy Shot once you reach Lv15) are effective. A Dogman later kills Torres Owens in the Weapons Department. Sheeva drops the M9-2 pistol (ATK 38+1).

Day 4: Conception

BOSS Spiderwoman (Hospital Rooftop)

A giant spider-like NMC on the hospital rooftop. She attacks with web projectiles that can immobilize Aya, and has a dangerous lunging attack when you get too close. Dodge web attacks by strafing constantly. Use the G3A3 rifle (found on the 13th floor) for sustained damage. The Spiderwoman drops the G23 pistol (ATK 47+1).

Day 5: Evolution

BOSS Slime Monster

The orange slime mass from Central Park's audience has become a giant monster. It surrounds Eve in an impermeable protective shield. You first fight it from a military helicopter — use your best weapons for aerial bombardment. It has sweeping slam attacks and projectile slime. The Slime Monster carries Eve away with its giant hand.

BOSS Eve (Liberty Island) - Multiple Phases

The final confrontation with Eve beside the wrecked Statue of Liberty. Eve has multiple phases, each more dangerous than the last. Attack from the helicopter first, then fight her personally on the ground. She uses powerful energy attacks — use Barrier (Lv13) to absorb damage with PE, and Haste (Lv20) to speed up your ATB. Use Energy Shot (Lv15) or Liberate (Lv33) for burst damage. Eve finally succumbs and dies at Liberty Island.

Day 6: Liberation

BOSS Ultimate Being (4 Evolving Forms)

The Ultimate Being is born from Eve and attacks the naval vessel. Its mitochondria cause it to evolve at an alarming rate through 4 forms, fusing with objects on the vessel. You MUST use Maeda's Gun with DNA Bullets — normal weapons cannot damage it. Each form is stronger than the last. Use Liberate (if at Lv33) for massive burst damage. After weakening it, set the vessel's boiler pressure dangerously high to destroy the ship, then escape before the cruiser explodes. The explosion kills the Ultimate Being.

Chrysler Building Bosses

The Chrysler Building (EX Game only) has 7 boss floors, culminating in the true final boss on Floor 77. Bosses appear every 10 floors.

BOSS Floor 10: Spiderwoman

Same as the Day 4 hospital rooftop boss, but stronger in the EX Game. Use rifles and machine guns. Dodge web attacks by strafing. The EX Game version has more HP.

BOSS Floor 20: Alligator x2

Two alligators at once, similar to the Day 1 sewer boss. Focus on one at a time. Keep your distance and use ranged weapons. They have powerful lunging attacks — don't let them corner you.

BOSS Floor 30: Centipede

A giant centipede with multiple segments. It drops the M79-3 grenade launcher (adds Frost effect). Use grenade launchers or shotguns for area damage. Target its weak points.

BOSS Floor 40: Triceratops

A reanimated Triceratops from the museum exhibits. It has powerful charging attacks and high defense. Use your strongest weapons — rifles and rocket launchers work well. Dodge its charge by moving perpendicular to its path.

BOSS Floor 50: Cockroach x2

Two giant cockroaches. They are fast and can swarm Aya. Use shotguns for burst damage against multiple targets. Keep moving to avoid being surrounded.

BOSS Floor 60: Crab

A giant crab with a hard shell. It drops the AT4 rocket launcher (ATK 128). Target its weaker points (underside, joints). Use high-damage weapons like rifles and rocket launchers to break through its shell.

BOSS Floor 70: Queen Bee

A Queen Bee and the bees she spawns. They are fast flyers that attack in swarms. Use machine guns (MP5PDW or better) for rapid fire against flying targets. Take them out one at a time to reduce incoming damage.

BOSS Floor 77: Truebred Eve (True Final Boss)

The true final boss of Parasite Eve, taking the form of Aya's deceased sister Maya. Dr. Klamp cultivated the cells of the original Eve as a backup — in case Melissa and the Ultimate Being failed, the purebred would remain. Truebred Eve has taken Aya's Liberate form and can use attacks similar to Aya's and more. This is the hardest fight in the game. Use your best weapons (DE50AE7, MAG, P90 from Junk rewards) and full PE. Use Barrier, Haste, and Liberate strategically. After defeating Truebred Eve, Aya's mitochondria rebel, but Maya's personality fights off the Eve persona and protects Aya. This unlocks the true ending.

EX Game (New Game+)

When the Normal Game is cleared once, a new mode called the EX Game appears — essentially a New Game+ (Plus). The EX Game is different from the normal game in several key ways:

Detail	Info
Item carryover	The player has access to every item stored in the police station. Plot items (keys, charms from Maeda) are removed.
Weapon/armor carryover	The game begins with the final weapon and armor the player chose before ending the first game.
Bonus Points (BP)	BP given at the end of the Normal Game are now available to use. Aya also receives set BP at the start of each day: 800 on Day 2, 1200 on Day 3, 2000 on Days 4 and 5, and 3000 on Day 6. Just playing through to the end of the Museum will get you at least 10,000 BP.
Enemy HP	Enemies have slightly more HP than in the Normal Game.
Level reset	Aya starts at Level 1 again, but gains more BP per level up than in the Normal Game.
Chrysler Building	The biggest difference — the Chrysler Building dungeon unlocks, containing the best weapons, armor, all Trading Cards, and the true final boss.

Chrysler Building (77 Floors)

The Chrysler Building is a progressive endurance dungeon available only in the EX Game. It contains the best items, armor, weapons, and Trading Cards in the game, plus the true final boss on Floor 77.

Structure

77 floors total, randomized except for floors 1, 10, 20, 30, 40, 50, 60, and 70-77.
Every floor (except the non-randomized ones) is completely randomized — each floor is like a maze.
Save points only every 10 floors, and only after defeating the boss on that floor.
The items, weapons, power-ups, and enemies are of a higher class than the main game.
New monsters include giant Squirrels, giant Cockroaches, and Queen Bees.
Most enemies and bosses are similar to those from the main game (Golden Rat, Alligator, Triceratops, Centipede).

Boss Floors

Floor	Boss	Notes
Floor 10	Spiderwoman	Same as Day 4 boss, stronger in EX Game
Floor 20	Alligator x2	Two alligators at once
Floor 30	Centipede	Giant centipede; drops M79-3 grenade launcher
Floor 40	Triceratops	Reanimated dinosaur; high defense
Floor 50	Cockroach x2	Two giant cockroaches
Floor 60	Crab	Giant crab; drops AT4 rocket launcher
Floor 70	Queen Bee, plus spawned bees	A Queen Bee and the bees she spawns
Floor 77	Truebred Eve	True final boss; form of Aya's sister Maya

Chrysler Keys (1-7)

Chrysler Keys are elevator keys that allow instant access to each 10th floor of the Chrysler Building, bypassing the randomized floors below. Each boss floor drops the key for the next block.

Key	Function
Chrysler Key 1	Elevator key to 10th floor
Chrysler Key 2	Elevator key to 20th floor
Chrysler Key 3	Elevator key to 30th floor
Chrysler Key 4	Elevator key to 40th floor
Chrysler Key 5	Elevator key to 50th floor
Chrysler Key 6	Elevator key to 60th floor
Chrysler Key 7	Elevator key to 70th floor

True Ending (Floor 77)

The boss on Floor 77 is Truebred Eve, the true final boss of the game. She takes the form of Aya's deceased sister Maya. Dr. Klamp cultivated the cells of the original Eve as a backup — in case Melissa and the Ultimate Being failed, the purebred would remain.

Truebred Eve has taken Aya's Liberate form and can use attacks similar to Aya's and more. After defeating her, the mitochondria inside Aya begin to rebel, as Aya's mitochondria have reached a higher evolutionary stage than Maya's. However, Maya's personality becomes dominant and fights off the Eve persona, protecting Aya by preventing the original Eve from taking over. Aya leaves the building alone, having gained a connection with her dead sister.

Chrysler Building Tips

Detail	Info
Recommended Level	Level 35+ before attempting the Chrysler Building. Aim for higher levels (40+) for the upper floors and Floor 77 boss.
Bring plenty of medicine	Stock up on Medicine 3 and 4, Full Recover, and Revive items. You can only save every 10 floors.
Use Save Points wisely	Save points appear only after boss fights on floors 10, 20, 30, 40, 50, 60, and 70. Don't waste them.
Chrysler Keys	Collect Chrysler Keys 1-7 to use the elevator for quick access to each 10th floor, bypassing the randomized maze floors.
Collect Trading Cards	Give all Trading Cards to Wayne to obtain Tool Kits and Super Tool Kits for unlimited weapon customization.
Customize your best weapon	Use Super Tools and Super Tool Kits to transfer the best parameters (Offense +4, Range +4, Bullet Cap +4) to a single weapon.
Distribute BP wisely	Invest BP in ATB speed, item capacity, and weapon/armor attributes. A faster ATB means more attacks per battle.
Watch for randomized floors	Floors 2-9, 11-19, 21-29, etc. are completely randomized. Explore thoroughly — the best items are often hidden in these maze floors.

The two endings

Parasite Eve has two endings, and neither is a choice you make in a menu. Which one you see depends entirely on whether you climb the Chrysler Building.

Swipe the table sideways

Ending	How you get it	What happens
1 — the standard ending	Finish the story: beat the four stages of the Ultimate Being aboard the cruiser on Day 6 and escape.	Two weeks later at Carnegie Hall, the audience's eyes glow as their mitochondria answer Aya's. Deliberately unresolved.
2 — the true ending	In an EX Game, reach floor 77 of the Chrysler Building and beat Truebred Eve, who wears the face of Aya's dead sister Maya and copies Aya's own Liberate powers.	The credits roll straight from that fight — you do not carry on to Day 6 in that run — and you get the closing artwork.

There is no third ending and no bad ending. Dying is just a game over. If a guide promises you a hidden third, it is wrong.

EX Game is New Game+. There is no separate mode. Finish the game, let the credits run all the way out, save the clear data, and EX GAME appears above New Game on the title screen. Aya drops back to level 1; enemy health and experience go up to match your carried-over gear.

What carries into EX Game — and what does not

Carries over	Lost
The one weapon and one armour Wayne engraved with Aya's name on Day 6	Everything else you were carrying when the final boss died
Everything left in police station storage	Plot items — keys and Maeda's charms are stripped out of storage
Your accumulated bonus points	Aya's level, which resets to 1
Your running Junk total already given to Wayne	—
Chrysler Keys and cleared floors	—

This is the single biggest run-breaker in the game. If you do not have Wayne engrave Aya's name on a weapon and a piece of armour before you leave for the docks on Day 6, you start EX Game carrying nothing. Nothing else in your hands survives.

And the trap inside the trap: if you are already carrying engraved gear from a previous run and you engrave new items, the old pair is lost when EX starts. Park the old customs in police storage first.

Puzzles — an honest list

Parasite Eve is a cinematic action-RPG, not Resident Evil. It has one real puzzle set, two switch sequences and a great deal of key-hunting. Guides that advertise a long puzzle chapter are padding. Here is everything that actually exists.

Museum quiz pedestals — Day 5

The interactive exhibit terminals in the Museum of Natural History. Each correct answer dispenses an item — medicines, ammo, or a Revive. This is the only genuine puzzle in the game, and it is easy to walk past.

Question	Answer
How many animals are hiding in the picture?	9
Which organelle appeared inside the first organism?	Mitochondria
What did the first organism, 3.9 billion years ago, feed on?	Nitrogen oxides produced by volcanoes
Mitochondria make ATP — how much energy does that represent?	About 200,000 volts per cubic centimetre
What was the consequence of taking mitochondria in?	Ageing
Which organism is thought to be Mitochondria Eve?	An African female
Oxygen in the air rose 25 million years ago. Why?	Photosynthesis carried out by bacteria

The quiz pedestals are spread across the floors and easy to miss — there are up to seven, so check every floor before you take the elevator.

St. Francis Hospital fusebox — Day 4

Not a logic puzzle, a fetch and a sequence. Find Fuse 1 on top of the bookcases in the library room, Fuse 2 on a medicine box in the autopsy area, and Fuse 3 in the bottom-right corner of the dark room. At the box: insert all three fuses one at a time, reconnect the wires, then switch the power on. The elevators come back.

Hospital reservoir pumps — Day 4

Master Power ON → run Pump 1 → run Pump 2 → Master Power OFF, then head north. The order of the two pumps does not matter. This drains the reservoir and lets the Giant Slime out.

The Slime is a free stat farm. It respawns every time you re-enter the room, and a Club-type weapon can steal from it — an unlimited supply of Defense +1. If you are going to grind anything in this game, grind here.

Chinatown sewers — Day 5

The same pump mechanic as the hospital, plus a ladder-and-drain route through to the subway tracks. Maeda hands you a charm on the surface first.

Hospital pipe wheels — Day 4

Past the green keycard doors, turn the wheels on the pipes in the bottom right to cut the liquid nitrogen feed to the sperm bank. If the wheels are not there, nothing else depends on them.

Things guides call puzzles that are not

Area	What it actually is
Museum, Days 2 and 3	Pure cutscene. Meet Dr. Klamp, hear the lecture, get thrown out. The museum only becomes a dungeon on Day 5.
Soho, Day 3	Two shops to loot. No codes, no order, no riddle.
Pier No. 3 warehouse, Day 5	A key hunt with one timing hazard — the Tool in the north-west corner sits behind venting steam. Grab it in the gap when the steam draws back into the pipe.
Carnegie Hall, Day 1	Key hunt. The Theater Key is on a burned body in the dressing rooms; the Rehearse Key comes out of Melissa's diary.
Central Park, Day 2	Key hunt. The Zoo Key is in a drawer in the zoo office.
Museum security office, Day 5	Not a puzzle, but easy to miss: walk off the right edge of the screen to find the concealed elevator to the 4th-floor storage room.
Chrysler Building	No puzzles at all. Randomised corridors and boss gates.

Every point of no return, by day

Swipe the table sideways

Day	What closes	What you lose
Day 1	Carnegie Hall and its sewers	The police cordon the building off the moment Day 1 ends and it never returns to the map. Sweep it — the M1911A1 is tucked in shadow near the sewer stairs, and there are chests behind the pillars and partitions.
Day 2	Central Park and the zoo	One visit only. Once the confrontation at the amphitheatre ends the day, the area closes.
Day 3	Soho — the gun store and the pharmacy	One visit only. Empty both, and take the Trading Card glinting in the rubbish outside. Speak to Cathy, Warner and Wayne before the day ends, because it ends on a forced fight.
Day 4	St. Francis Hospital	One visit only — and there is a smaller trap inside it. The hidden box behind the overturned cabinet can be searched repeatedly for Trading Cards, but only while you are in that room the first time. Empty your inventory before you open it. Leave and it is gone.
Day 5	The Pier No. 3 warehouse	Optional and Day-5 only. Skip it and you lose the AT4 rocket launcher, the PPK, an M203-2, several armour pieces and a Defense +2 for that run.
Day 5	The Museum's 4th floor — the big one	Taking the hidden elevator in the security office up to Eve ends Manhattan permanently. No city map, no shops, no police storage, and no Chrysler Building for the rest of that playthrough. In an EX run this is where you forfeit the true ending.
Day 6	Leaving for the docks	This is your last chance to have Wayne engrave Aya's name on a weapon and on a piece of armour, and your last chance to put anything into police storage. After that, Day 6 runs straight to the credits.

Junk, Wayne, and picking your own gun

Junk looks worthless and is the most valuable thing in the game. Hand it to Wayne at the 17th Precinct; at 300 Junk he builds you one ultimate weapon of a class you name. The earliest that can happen is Day 4, after the police department. Your total is cumulative and carries across EX rounds, so 600 gets a second gun and 900 a third.

Swipe the table sideways

You ask for	Gun	Attack	Ammo	Slots	Notes
Pistol	DE50AE7	123	15	8	The usual pick — the widest slot count of the six
Machine gun	P90	122	200	5	The other popular build: huge magazine, fewer slots
Rifle	MAG	151	20	4	Highest raw damage
Shotgun	M10B	120	6	4	—
Grenade launcher	HK40	115	8	6	Good slots, awkward to aim
Rocket launcher	LAW80	200	1	0	Cannot have slots added by any means

Never pick “leave it to Wayne”. That rolls a junk-tier weapon — an AK-47 with 6 slots, a PPsh41 with 2, an SP1C with 2, a USP-TU with 3 — or simply hands you more Junk. Three hundred Junk, wasted.

Where to farm it: the birds in Central Park and the enemies on Chrysler floors 2–10 drop Junk constantly and come in packs. The frogs in the Chinatown sewers, the lizards in the Museum and the slimes above floor 61 also work. A Club can steal Junk outright.

Tools, Kits and the slot ceiling

Four items do the same job — moving one parameter or effect from item A to item B. The difference is what survives.

Item	Uses	The donor item
Tool	One transfer	Destroyed
Super Tool	One transfer	Survives
Tool Kit	Unlimited	Destroyed
Super Tool Kit	Unlimited	Survives

So super means the item you are stripping does not break. It does not mean “removes modifications”, which is how several guides describe it. Once you hold a Kit, loose Tools are dead weight — the Kit sets your counter to 999.

The Tool Kit needs about 11–12 rare Trading Cards, and the Super Tool Kit needs 14. The tower holds roughly 14 rare cards, so it works out — keep feeding Wayne rare cards and you will cross both lines.

The slot ceiling

Every weapon and every piece of armour has two numbers: the slots it spawns with, and the most it can be expanded to. A Mod Permit or a normal Trading Card adds one slot; a rare Trading Card adds two to one item, or one each to two items.

Claim	Status
The game-wide ceiling is 10 slots	Yes — the hard cap is 10
Cr Armor 2 — 7 base, 10 max, the best armour in the game, found on floors 61–70	Yes
Which weapon actually reaches 10	The M92F is the one you can take all the way to 10, from a base of 3.
Anything above 10 slots	Does not exist in normal play — the only 10+ entry is an unused debug weapon you cannot obtain.

Printable 100% checklist

Both playthroughs, in order. Print it and keep it beside you — the print version drops the menus and images.

First playthrough — the normal game

Carnegie Hall swept before Day 1 ends (M1911A1 near the sewer stairs)
Central Park swept before Day 2 ends
Soho — gun store and pharmacy emptied, Trading Card from the bins
All 7 museum quiz pedestals answered
St. Francis Hospital — the hidden card box searched until it is empty
Both Super Tools found and put into police storage
Pier No. 3 warehouse cleared for the AT4
300 Junk handed to Wayne, and you chose the weapon class
Wayne engraves Aya's name on one weapon and one armour — Day 6, before the docks
Everything worth keeping deposited in police storage
Ultimate Being beaten → ending 1
Credits watched to the very end, then the clear save made → 3,000 bonus points and EX Game

EX Game — the Chrysler Building

EX Game started from the title screen (Aya returns to level 1)
Chrysler Building entered from the city map on Day 2
Floor 10 boss → Chrysler Key 1
Floors 20, 30, 40, 50, 60, 70 → Keys 2 to 7
Cr Armor 2 found in the floors 61–70 band
Rare Trading Cards farmed → Tool Kit, then Super Tool Kit at 14
Weapon and armour tuned with the Kits across as many EX rounds as you want
Floor 77 — Truebred Eve beaten → ending 2, the true ending
The Museum 4th floor avoided until the tower is finished

About trophies

There are none, on any platform. Parasite Eve went to the PlayStation Store in March 2011 as a PSOne Classic for PS3, PSP and Vita — never in Europe, because the game never had a European PS1 release — and PSOne Classics were never given trophy support. Trophies for classic PlayStation titles only arrived with the PS Plus Premium reissues from 2022, and Parasite Eve is not in that catalogue.

If you want a checklist to tick, the list above is it. There is also a community-made achievement set on RetroAchievements — unofficial, not Sony trophies.
