This page is for direct answers: puzzle solutions, side-job routing, collectible cleanup, missables, upgrades, and Steam Deck settings.
If you are stuck, start with the exact guide you need instead of a full walkthrough. The library below is organized by the questions players actually hit during a run.
How to use this page fast
- Start with the exact blocker: puzzle, side job, collectibles, missables, or Steam Deck settings.
- Open the matching guide below instead of a generic walkthrough.
- If you are doing a full clear, check the missables and side-job pages before pushing the next main mission.
- Use the Steam Deck and review pages only when your question is about performance or whether the game is worth buying.
Start with these
- Police Station Lever Puzzle Solution Exact solutions for the 26 and 35 target lever puzzles in A Bit of a Scene, including the optional safe reward.
- All Shrewd Shrews Door Codes Every code for the The Depths keypad door, where each clue is hidden, and what each correct entry gives you.

- Steam Deck Best Settings Recommended 40 FPS Steam Deck settings, optional 60 FPS tweaks, and the trade-offs behind each setup.
What this hub helps with
- Police Station Lever Puzzle if you are blocked in A Bit of a Scene.
- Shrewd Shrews Door Codes if The Depths keypad is stopping progress.
- Perfect Bog Fondue Thingies if Damp Evidence cleanup is slowing you down.
- Steam Deck Best Settings if you want a stable handheld setup first.
Every page in this hub is here to solve a player problem. If a guide does not help you clear a mission, finish a side job, protect a collectible run, or set the game up properly, it does not belong here.
