Run the customer check
Do not decide from a familiar face. Story shifts are randomized and a known customer can return in a different state. Work through independent evidence, then follow the game prompt.

Guide coverage
Built for a full Story Mode run
Start with the customer check, then use the ending, achievement and equipment files only when that decision arrives.
The shift count, intended player count, investigation loop and current Endless Mode roadmap come from the official Steam listing. Achievement and ending totals are corroborated by the linked completion guides.
Use this guide without spoiling the run
Start spoiler-light
Use the main guide and customer checker for the repeatable station loop. They avoid story outcomes.
Open case files as needed
Weapons, traps, pets and multiplayer pages answer one task without forcing a full walkthrough.
Plan the final shifts
Night 13, endings and achievement pages are clearly marked for spoilers and completion runs.
Re-check after updates
Red patch-sensitive labels identify facts that may move when Bun Muen changes balance or content.
Quick answers
Frequently asked questions
Is the checker a guaranteed answer?
No. It organizes the ID, NET, photo and answer evidence you observe. The current in-game record and prompt remain the source of truth.
Is Story Mode the same every run?
No. The official listing describes all 13 Story Mode shifts as randomly generated, so customer order and encounters can vary.
Does this site contain ending spoilers?
Only pages marked with the red spoilers label reveal ending conditions. The homepage checker and beginner guide stay spoiler-light.
