GRAIN ROT Controls Reference
Keyboard, mouse, controller, and Steam Deck — all input options explained.
GRAIN ROT supports keyboard and mouse as primary PC input plus full controller support including Xbox, PlayStation, Switch Pro, and Steam Deck layouts via Steam Input. Controls may receive polish before the August 7, 2026 launch, but demo footage confirms standard first-person movement, context interactions, building rotation, grab mechanics, and emote triggers.
Use this hub to jump to detailed binding references and accessibility notes before your first elevator descent.

Input features on Steam
The Steam store lists full controller support, custom volume controls, captions, playable without timed input, and stereo sound. These matter for co-op horror accessibility — players sensitive to loud Grinder screams should lower SFX before tutorials.
Controls and core mechanics
Certain actions overlap across systems:
- Demolition — mallet swings on destructible props
- Grab / throw — physics interactions for loot and trolling
- Build rotation — placing constructs in Outpost and some underground contexts
- Emotes — including cursed emotes that can affect stealth
Mechanic depth lives in Getting Started and Co-op & Spark Mechanics, not in this hub.
Rebinding and Steam Input
PC players can remap via Steam Input even when in-game rebinding menus are limited in demo builds. Community configs on Steam Input DB include hybrid keyboard-plus-pad layouts for GRAIN ROT Demo — see the controller page for details.
System requirements tie-in
Minimum specs require keyboard and mouse at minimum; controllers are optional but recommended for couch co-op. Read release date and price for full PC requirements.
Cross-platform co-op input notes
Mixed keyboard and controller squads are normal in GRAIN ROT online co-op. Keyboard players often handle precision demolition while controller players anchor doorways with analog strafing. No in-game advantage is tied to input device — communication matters more than hardware.
Document house rules for emote keys before deep layers. Accidental cursed emotes during stealth segments can trigger Corrupted chains that keyboard players blame on controller layout confusion.
