How to use the official achievement list
Treat the wording below as the objective, not as a promise about when Steam will display the unlock. Some conditions happen during a mission, some depend on progression, and several clearly span the Endless Bunker mode. Keep the Steam client online when practical, allow the game and client time to synchronize, and confirm the achievement in the Steam library before repeating a completed condition.
The official page also publishes global completion rates, but those values are not copied here. They change continuously and do not explain how difficult a condition will be for a particular player or squad. The stable search value is the complete name and condition inventory. Strategy notes stay at the level supported by the wording and the game systems already documented by official sources.
- Count verified on the official page: 19 achievements.
- Source boundary: names and conditions come from Steam, while planning notes are clearly editorial.
- Freshness rule: recheck the verification time after an Early Access update.
- No rarity percentages, hidden triggers, or guaranteed unlock timing are claimed.
Tutorial and equipment achievements
The first group can be read directly from onboarding and ordinary item use. TOTAL RECALL asks the player to start the tutorial once again, while Thy light shone asks for tutorial completion. These two conditions make the tutorial a useful place to confirm controls and interaction basics before combining achievement hunting with a longer bunker objective.
Insurance Not Included is tied to breaking an item through use. The condition does not identify a required item, durability threshold, or mission route, so this guide does not add one. Use the exact official wording, observe normal equipment wear, and avoid treating an old clip or a single player report as proof of an undocumented shortcut.
- TOTAL RECALL: Start tutorial once again.
- Thy light shone: Complete the tutorial.
- Insurance Not Included: Break an item through use.
Extraction and squad experiment achievements
Several achievements reward unusual run stories rather than a fixed combat route. Save Private Cat requires extracting from a mission with a cat. FOR SCIENCE requires killing a teammate in a Crusher. Hangover requires drinking until the player passes out, and RAT FLIP asks for exactly what its name suggests. Coordinate disruptive attempts with the squad so an optional objective does not silently replace the shared mission plan.
The official conditions do not publish a specific map seed, spawn point, item count, or sequence for these objectives. Use ordinary in-game feedback and current object labels, preserve the main extraction plan, and date any personal note by build. For co-op objectives involving another player, get agreement before committing the run to the experiment.
- Save Private Cat: Extract from a mission with a cat.
- FOR SCIENCE: Kill a teammate in a Crusher.
- Hangover: Drink until you pass out.
- RAT FLIP: Do a rat flip.
Transformation and encounter achievements
The official ledger now provides reliable names for several threats that were not documented well enough for individual guide pages at launch. YOU ARE MINE references THE GODDESS and transformation into a GHOUL. Clunker Killer names THE FERNAUGHT, Service Malfunction names an overcharging Ferablower, and Batbuster names the BATTALION. Their achievement descriptions establish the targets and outcomes, but not complete encounter scripts.
Use the boss guide for observation, spacing, resource ownership, and recovery planning. Do not convert these achievement lines into invented health values, phases, counters, or drop tables. When an encounter produces new information, separate the visible cue from the interpretation and compare it with current official material before publishing a more specific claim.
- YOU ARE MINE: Get caught by THE GODDESS and transformed into a GHOUL.
- Clunker Killer: Defeat THE FERNAUGHT for the first time.
- Service Malfunction: Get killed by an overcharging Ferablower.
- Batbuster: Defeat the BATTALION for the first time.
Endless Bunker and progression achievements
The longer objectives benefit from a simple tracking plan. One Day in Eternity, Five Nights at the Bunker's, and 7 Days to Extract all name survival milestones in Endless Bunker mode. DOUBLE TAP spans two B.O.S.S. targets in one save. Grand Magus, Grinder, Cat Person, and ABSOLUTIST depend on broader progression rather than one isolated room interaction.
Before starting a long attempt, confirm which save and mode are active, choose a consistent point to review progress, and avoid resetting a run based on an unverified hidden requirement. The achievement names do not establish shop costs, upgrade order, cosmetic locations, or whether progress can change during Early Access. Read current in-game shop and save information for those details.
- One Day in Eternity: Survive your first day in Endless Bunker gamemode.
- Cat Person: Unlock every earnable cat cosmetic.
- DOUBLE TAP: Kill the first two B.O.S.S. targets in one save.
- Five Nights at the Bunker's: Survive five days in Endless Bunker gamemode.
- Grand Magus: Learn every spell available in the shop.
- Grinder: Unlock every upgrade in the Hub Shop.
- 7 Days to Extract: Survive seven days in Endless Bunker gamemode.
- ABSOLUTIST: Complete every achievement.
Troubleshoot achievement tracking safely
If an expected unlock does not appear, first confirm the exact official condition, current save, mode, and Steam client state. Allow synchronization, restart only through normal controls, and preserve the save before trying any reversible troubleshooting. Do not download an unknown save editor or disable security controls to force an achievement. A missing notification is not enough evidence to declare a current game bug.
Record the achievement name, visible in-game result, build context, session mode, and whether the Steam library later updated. Check official announcements and the Steam Community hub for a current notice. If none exists, describe the observation as a report rather than a confirmed issue. This keeps the achievement guide useful through Early Access without turning individual experiences into unsupported universal rules.
