RATSHAKER™ Patch Notes — March 27, 2026
Aggregated from Steam, cross-tracked with Battle.net coverage on GamePatchNote.

Hey RATSHAKERs,
You thought we’d stop with RAT-CHAN? No, no, no. The rot never rests, the vermin never sleep, and we are never done fixing things that should have worked in the first place.
Fixes:
- All audio added in the RAT-CHAN DLC is now correctly affected by volume sliders.
- RAT-CHAN dialogue is now 2x louder!
Additions:
...
