Practical Notes
- The specs are modest — a GTX 970-era card runs it. The game's load is physics simulation, not ray tracing: destructible furniture, ragdoll vessels and four-player chaos are CPU-side work.
- Broadband is required even for solo play per the Steam listing.
- Headphones are a gameplay upgrade, not a luxury: directional screams and the audio mix are core mechanics — crews assign a dedicated audio caller. See co-op roles.
- Gamepad support arrived with the 1.0 release; keyboard and mouse remain the default.
Platforms
GRAIN ROT is PC-only at launch (Steam). No console version has been announced. Steam Deck compatibility hasn't been officially rated — the recommended tier (RTX 2060-class) suggests Deck play may require settings compromises; check community reports as they mature.
