BioShock · Volume 2 of 3BioShock 2 - The Complete 100% Walkthrough

Every level. All 129 main-campaign audio diaries and all 14 Power to the People stations. Every trophy, including the Platinum, all 24 Protector Trials, and Minerva's Den's own self-contained campaign with its own diaries and Vacuum Bots. Written for BioShock: The Collection on PS4/PS5/Xbox/PC; where the original 2010 release differs, the difference is noted.

1. What "100%" Means in BioShock 2

BioShock 2 (2K Marin, 2010; remastered into BioShock: The Collection, 2016) puts you inside a Big Daddy instead of hunting one. Subject Delta wakes on the ocean floor a decade after Sofia Lamb forced him to put a gun in his own mouth, drawn back to Rapture by a telepathic call from Eleanor, the Little Sister he was bonded to and never stopped protecting. Where BioShock 1 asked what a man does with power, this one asks what's left of a man once the choice is made for him, over and over.

Same spread-across-many-systems structure as the first game, with two full DLC campaigns folded into one 54-trophy list:

• The story and its difficulty tiers: one playthrough, plus the hardest difficulty and a no-Vita-Chamber run for the Gold trophies. The ending depends on every Little Sister and NPC choice you make along the way.
• 129 main-campaign audio diaries: the Silver Rapture Historian only needs 100 of the 129 — up to 29 can go unfound and the trophy still pops, though this guide routes all of them regardless.
• 14 Power to the People stations: two per weapon across seven weapons. All fourteen earns the Silver All Weapon Upgrades.
• Research, hacking and invention: a research camera ledger, a real-time Hack Tool ledger (Master Hacker, Prolific Hacker), and a plasmid/tonic ledger (All Plasmids, Max Plasmid Slots).
• The Little Sisters: gathered, not just found. Escort one to a corpse, defend her through a live, timed ADAM gather, then choose to rescue (80 ADAM) or harvest (160 ADAM) afterward. Saving every one, plus sparing three named NPCs, earns the secret Silver Savior and the game's best ending.
• Protector Trials (DLC, merged into this list): 24 trials across 6 areas — 18 numbered plus 6 bonus — worth 36 stars total.
• Minerva's Den (DLC, merged into this list): a self-contained 3-level campaign as a different Big Daddy, Subject Sigma, with its own 35 diaries and 10 Vacuum Bots that do not count toward Rapture Historian.

Tip. Little Sister choices and NPC spare/kill decisions are permanent per-save the moment you make them — there's no chapter-select to walk them back later. Decide your policy (§4) before your first Gather, not partway through.

Spoiler policy

The routes below describe what each level contains and where the story goes, in a line, not a retelling. The reveals — what happened to Eleanor, what Sofia Lamb actually wants, how it ends — stay yours to watch.

2. How to Use This Guide

Two kinds of pickup get an inline badge, in route order, restarting at 1 in every level:

Minerva's Den's own 35 diaries and 10 Vacuum Bots (§13) are real and worth finding, but research didn't turn up reliable per-item locations for them the way it did for the main campaign, so this guide reports their counts honestly rather than inventing badge-tagged routes for them.

An entry like JE5 Ryan vs Lamb: Reality means "the fifth diary of the current level, in route order." Trophy moments and mechanics appear as callouts exactly where they happen.

Diaries hide the same way they did in Rapture the first time: desks, corpses, cabinets, the occasional locked room behind a keypad code this guide gives you. Power to the People stations are large, humming machines you can hear from a room away — same access-not-visibility challenge as before.

BioShock 2 has no chapter-select, same as the first game. A handful of areas (Adonis Luxury Resort, the earlier halves of several levels once their gates lock behind you) are gone once you leave. Sweep a room before you move on.

3. The Road to 100%

    NGP --> HARD["Against All Odds - hardest difficulty<br/>Big Brass Balls - no Vita-Chamber<br/>(one run clears both)"]
    HARD --> PLAT(["PLATINUM"])

The road to the Platinum. Everything collectible happens on pass one and the two DLC campaigns; only the difficulty pair needs a second, harder run.

Why this order?

1. Collect on your first pass, same as BioShock 1. No chapter-select means this playthrough is your one real shot at diaries, research, and hacking variety before areas seal behind you.
2. Little Sister policy, decided up front. Rescue every one you can and spare Grace Holloway, Stanley Poole and Gil Alexander for Savior and the best ending; the choice is permanent per NPC the moment their scene resolves.
3. Do the DLC on the same pass, not after. Protector Trials and Minerva's Den are separate menu entries with their own saves — nothing about them depends on main-campaign progress, so there's no reason to save them for later.
4. Difficulty and no-Vita-Chamber last, together. Against All Odds (hardest difficulty) and Big Brass Balls (no Vita-Chamber) are independent trophies, unlike BioShock 1's Survivor-tier pairing — one clean run at the top difficulty with Vita-Chambers off clears both at once.

Where the game takes you

timeline
    title The shape of Rapture, ten years on
    section Arrival - Adonis Luxury Resort and the Atlantic Express
        Adonis Luxury Resort : Revival, the first Big Sister, a decade gone
        The Atlantic Express : Sinclair's voice, the railway restarted
    section Lamb's city - Ryan Amusements through Dionysus Park
        Ryan Amusements : Propaganda, the first Gather, Sinclair in person
        Pauper's Drop : Grace Holloway's slum stronghold
        Siren Alley : Simon Wales' cult, Grace's reckoning
        Dionysus Park : Stanley Poole's betrayal, surfaced
    section Closing in - Fontaine Futuristics and Outer Persephone
        Fontaine Futuristics : Gil Alexander, the Alpha Series, a rival hunter
        Outer Persephone : Lamb's old prison, Sinclair's fate turns
    section The reckoning - Inner Persephone
        Inner Persephone : Delta and Eleanor against Lamb, the ending decided

Nine levels, one decade-late homecoming. Pauper's Drop and Siren Alley between them carry more than 40 diaries.

4. Mechanics Worth Knowing Before You Start

• You dual-wield. Weapon in the right hand, Plasmid in the left, both live at once — no menu-swap like BioShock 1. Learn a shock-then-drill or freeze-then-shotgun combo early; it's the whole combat language of this game.
• The Drill replaces the Wrench, with its own fuel gauge (300 cap) for spin attacks and a Drill Dash charge that doubles as an offensive lunge and an interrupt against a charging Big Sister.
• Hacking is real-time, not paused. A needle bounces across red/green/blue zones on a gauge while enemies can still reach you; Hack Darts let you hack at a distance, unlike BioShock 1's stand-next-to-it requirement. Skilled/Master Hacker counts every hack method — darts, manual, or otherwise — same generosity as the first game.
• Little Sister Gathers are a live defense encounter, not an instant choice. Carry her to a corpse, and for several seconds she gathers ADAM (40, or 60 with the Proud Parent gift) while Splicers converge; every enemy that reaches her drops the take. Afterward: Rescue (80 ADAM) or Harvest (160 ADAM) — flat immediate harvest skips the gather entirely for 160 ADAM with no defense needed.
• Big Sisters show up once every Little Sister in an area is resolved. They have an exposed tank on their back and a chargeable Drill Dash interrupts their own charge.
• Vita-Chambers toggle off any time from Options, not just at a fresh start — and Little Sisters passively heal their bonded Big Daddy, so BioShock 2 discourages Vita-thrashing by design rather than by trophy technicality alone.
• Savior needs more than saving every Little Sister. It also requires sparing three named NPCs at their confrontation scenes: Grace Holloway (Pauper's Drop/Siren Alley), Stanley Poole (Dionysus Park), and Gil Alexander (Fontaine Futuristics). Killing any of the three forecloses Savior for that save.
• Up to 8 Plasmid slots, unlocked progressively from a starting 3 — Max Plasmid Slots wants every one of them purchased.

Warning. "Master Protector" is the name of both a base-game Bronze trophy (a no-damage, no-breach Gather) and a Minerva's Den-unlockable tonic (earned by finishing all 36 Protector Trials stars). They share nothing but a name; don't confuse one for the other while tracking your checklist.

5. The Master Checklist

Main-campaign diary and P2P counts, with running totals. Minerva's Den and the Protector Trials keep their own separate ledgers (§12, §13).

Rapture Historian needs 100 of these 129 — route every one below and the trophy is never in doubt.

6. The Trophy List - All 54

1 Platinum, 4 Gold, 17 Silver, 32 Bronze. Marked by source: main campaign, Protector Trials, or Minerva's Den — all three feed this one list on the Collection.

Platinum & Gold

Silver

Bronze - main campaign

Bronze - Protector Trials

Bronze - Minerva's Den

PS3-original differences, in one breath: the 2010 disc shipped with an asynchronous online multiplayer mode ("Fall of Rapture") carrying its own trophy list (51 base trophies, several multiplayer-only) plus a separate Rapture Metro Pack DLC list. BioShock: The Collection removes multiplayer entirely — none of those trophies exist here, and every trophy on this 54-entry list is single-player.

7. Levels 1-2 - Adonis Luxury Resort & The Atlantic Express

Level 1 - Adonis Luxury Resort

Collectibles: 7 audio diaries.

Ten years dead, Subject Delta wakes on the ocean floor to a voice that isn't Atlas this time. It's Eleanor, grown up, calling the only father she remembers.

1. Adonis Baths, first large room, pillar base at the NE corner in front of the sparking generator: JE1 Attention: Workers!
2. Electro Bolt and Delta's starting weapon come first; nothing about this opening can be missed.

4. Women's restroom off the corridor south of Adonis Baths: JE3 To My Daughter.
5. Bridge/wading-Splicer room, on a bench under a wall poster, SW end: JE4 Return.
6. Bathysphere Docking area, beside an open suitcase: JE5 They Called It Rapture.
7. Grand Foyer/cocktail lounge, bar counter near the Vita-Chamber — after the first Big Sister encounter: JE6 Generation.

Trophy chance. The Big Sister here steals a Little Sister and flees rather than fighting to the death; this is scene-setting, not yet a fair fight.

1. Ocean-floor walk at the level's end, corpse inside a crashed bathysphere near the fallen resort sign: JE7 Escape from Rapture.

Level 2 - The Atlantic Express

Collectibles: 8 audio diaries.

The derelict rail depot that once served Rapture's whole transit system. Delta allies with a radio voice — Augustus Sinclair — to get a train running toward Ryan Amusements and, eventually, Eleanor.

1. Workshop 6A, south side of the train platform, on a desk: JE1 The Great Chain Rattles.
2. Flooded corridor after the first Lamb radio contact, behind a turning fan — needs Telekinesis to pull free: JE2 Mr. Tape Recorder.

Level 3 - Ryan Amusements

Collectibles: 19 audio diaries · 2 Power to the People stations.

9. Levels 5-6 - Siren Alley & Dionysus Park

Level 5 - Siren Alley

Level 6 - Dionysus Park

Collectibles: 15 audio diaries · 2 Power to the People stations.

Once an elegant botanical park, and Eleanor's childhood home before administrator Stanley Poole sold her out to silence what she'd caught him doing.

17. Train Station Security Booth: JE15 A Plan.

Trophy - Nose for News. Harvesting ADAM from the Little Sisters gathering here triggers telepathic memories exposing Stanley Poole's betrayal of Eleanor — this is what the secret trophy is watching for.

10. Levels 7-8 - Fontaine Futuristics & Outer Persephone

Level 7 - Fontaine Futuristics

Collectibles: 17 audio diaries · 2 Power to the People stations.

Frank Fontaine's old genetics labs, now Sofia Lamb's base of operations. Delta meets a rival Big Daddy hunter, "Alex the Great," and fights the first Alpha Series Big Daddies of the game.

1. On crates, before the 1st flood door: JE1 Alone at Last.
2. Wall pickup, before the 2nd flood door — story-required, can't be missed: JE2 Agnus Dei.
3. Couch by the pinned Splicer, before the 2nd flood door: JE3 Means of Control.
4. Up the stairs by the vent, before the 2nd flood door: JE4 Life After Sisterhood.

18. Locked room, hack the door panel: JE16 Big Sister.
19. Floor near a Big Daddy helmet, end of the level: JE17 The People's Daughter.

Level 8 - Outer Persephone

Collectibles: 5 audio diaries · 1 Power to the People station.

Sofia Lamb's own former cell block, now her stronghold. Short, tense, and the level where Sinclair's fate turns.

11. Level 9 - Inner Persephone

Collectibles: 17 audio diaries · 2 Power to the People stations.

The finale. Delta and a grown Eleanor try to reach a lifeboat Sinclair docked for them; Lamb floods its ballast tanks to keep it grounded, and the last fight plays out in the nursery wards while Eleanor works to drain them.

19. Infirmary Autopsy Room, on the sink: JE17 Alleviating Pain.

Trophy - Escape and Reunion. The finale's ending sequence resolves both: escaping Rapture at all, and (if you've kept Eleanor's bond intact) the reunion the whole game has been building toward. Which of the game's several endings plays depends on your full Little Sister and NPC ledger — everything decided in §§7–10.

12. Protector Trials - The Full Roster

Twenty-four trials across six areas, each revisiting a main-campaign location as a different, unnamed Alpha Series Big Daddy. Every trial's objective is the same: escort a Little Sister to an ADAM-rich corpse and defend her through a roughly four-minute Gather. An unbroken gather builds a multiplier up to x4; every enemy that reaches her knocks it back down. Enemies drop no loot here, so hack or buy from vending machines before the timer starts.

Each area's structure is identical: Trial 1 (1★), Trial 2 (2★), Trial 3 (3★) — 6★ per area, 36★ across all six. A bonus trial unlocks per area once its three numbered trials clear; no rank requirement, just completion, and it hands you every weapon and Plasmid at max upgrade for a harder victory lap. Clearing all six bonus trials also unlocks the Master Protector tonic, usable back in Minerva's Den.

Rank (D through A+) measures the percentage of that trial's total available ADAM actually collected — roughly 80%+ for an A, close to 100% for an A+.

13. Minerva's Den

A self-contained campaign, not a main-game chapter — its own menu entry, its own save, roughly 3-5 hours. Collectibles: 35 audio diaries · 10 Vacuum Bots.

You play Subject Sigma, an early Alpha Series Big Daddy, guided by a voice claiming to be Charles Milton Porter — the engineer who built Rapture's ADAM-powered supercomputer, The Thinker. Opposing you: Reed Wahl, Porter's former colleague, now consumed by the machine's predictive power. Progression is strictly linear across three levels; there's no backtracking, so clear each area fully before its exit.

Minerva's Den (Rapture Central Computing)

Den Entrance, the Executive Wing, McClendon Robotics, and the Air-Tite Archives.

• 20 of the campaign's 35 diaries are here — this level alone carries more diaries than several main-campaign levels combined.
• 5 of the level's 10 Vacuum Bots patrol the Executive Wing and McClendon Robotics — destroy each on sight; they don't fight back hard, but they're easy to walk past unnoticed. Research didn't turn up a reliable per-bot location list, so this guide doesn't pretend to route each one individually; watch and listen as you clear each room instead.
• The Drill Dash tonic (DLC-exclusive) is found in the Security Bot showroom, McClendon Robotics, or purchasable for 75 ADAM.
• The Gravity Well Plasmid (also DLC-exclusive) is found at the Manager's Office desk in the Air-Tite Archives, or purchasable at this level's Gatherer's Garden.

Operations

Operations Entrance, the Machine Graveyard, Programming, Ventilation Control, and Core Access.

• The remaining 13 diaries route through here.
• The remaining 5 Vacuum Bots patrol Operations — clear all ten across both levels for Garbage Collection.
• The Spitfire arcade cabinet sits in the Programming wing. Score 9999 for High Score — it's a fixed-pattern shooting minigame, not luck; a couple of practice runs are usually enough once you learn the pattern.
• Reaching Rapture Central Computing Operations here is the story beat behind the Login trophy.

The Thinker

The Mainframe, Core Access, the supercomputer chamber itself, and Porter's Apartment.

• The final 2 diaries close out the 35-diary total.
• Reaching Computer Core Access earns Root Access Granted; wresting control of The Thinker from Reed Wahl in the finale earns the secret SUDO.
• The campaign's emotional core — Porter's late wife Pearl, and a twist tying Sigma directly to Porter's own identity — resolves in the final confrontation with Wahl at the Mainframe. Escaping afterward is Logout.

Tip. None of Minerva's Den's 35 diaries or 10 Vacuum Bots count toward the main campaign's Rapture Historian or any main-campaign trophy — it keeps its own save and its own ledger entirely.

14. Cleanup - Farming Recipes and Checklists

No chapter-select here either, so this is a pre-flight list for your one main-campaign pass (§7-§11) plus the two DLC campaigns (§12-§13), not a post-game farm.

Little Sister and NPC policy, stated plainly

Rescue every Little Sister and spare Grace Holloway, Stanley Poole and Gil Alexander for Savior and the best ending. There's no route that earns both Savior and a harvest-heavy ADAM budget on the same save — decide before Ryan Amusements' first Gather, the same way BioShock 1 asked you to decide before its own first encounter.

15. Difficulty

Against All Odds (hardest difficulty) and Big Brass Balls (no Vita-Chamber) are independent trophies — unlike BioShock 1's stacked Survivor tier, BioShock 2 lets you clear both in a single run at the top difficulty with Vita-Chambers disabled from the Options menu.

• Vita-Chambers toggle off any time, so there's no need to start a dedicated New Game Plus the way BioShock 1's Survivor run demanded — carry your existing save's Plasmids and Tonics into a fresh top-difficulty attempt if the game offers it, or start clean with the game's harder pacing in mind.
• Little Sisters passively heal their bonded Big Daddy, which works against you here: don't linger near an unresolved Little Sister mid-fight if you're trying to keep a clean no-hit record for Grand Daddy or Master Protector.
• Big Sisters are the main threat to a no-death run: bait her charge, then Drill Dash through the opening it creates.
• The Protector Trials' hardest area (Persephone Cellblock F, §12) is good practice for the finale's Alpha Series Big Daddy fights before you attempt them on your hardest-difficulty run.

17. Accuracy & Sources

This walkthrough was written fresh for this document, then cross-checked against the BioShock Wiki (Fandom), GameFAQs, PSNProfiles and TrueTrophies (all consulted August 2026). The 54-trophy total and its 1/4/17/32 tier breakdown were counted directly from itemized trophy data and matched an independent spot-check exactly, as did the 129-diary main-campaign total (cross-validated twice: once by direct citation, once by summing all nine per-level lists) and the 14-station Power to the People count.

One genuine correction worth flagging: this guide's Protector Trials research started from an assumed count of ten trials. That premise didn't survive contact with actual sources — the real structure is 24 trials across six areas (18 numbered plus 6 bonus), confirmed by the BioShock Wiki, GameFAQs, PSNProfiles, TrueTrophies and Steam community guides, and independently corroborated by the trophy list's own math (6 areas × 6 stars = the 36 stars "Trial By Fire" asks for). The number below is the corrected one.

One unresolved title collision: "Truth is in the Body" appears as a diary title in both Ryan Amusements and, in some references, Dionysus Park (where an older title, "The Voice of the Self," may be the one the Collection actually kept). This guide lists Ryan Amusements' diary as "Truth is in the Body" and keeps Dionysus Park's as "The Voice of the Self" per the source material's own best judgment; if your in-game tracker shows differently, trust your tracker over this page.
