FAQ
Answers use only sourced facts; unverified items are marked.
- What is GRAIN ROT?
- It is a horror co-op extraction builder from Beck & Branch Games where you play a Living Spark inside fragile wooden vessels. You ride a cursed elevator into shifting underground ruins, smash furniture and process valuables for gold, fight or avoid the Corrupted, and rebuild the Outpost between runs.
- When did GRAIN ROT release and what does it cost?
- It launched on Steam for Windows on August 7, 2026 at $8.49 during a launch promotion, down from the $9.99 list price. SteamDB records the store release at 14:55 UTC that day and confirms the game is not in Early Access.
- How many players can play GRAIN ROT together?
- The unofficial wiki lists 1-4 player online co-op, and community posts in the Steam discussions say the game is designed around four players but does not enforce a hard cap. One player reported a six-person session running about five hours without issues, which remains unconfirmed.
- What happens when your vessel breaks in GRAIN ROT?
- Your Living Spark escapes and you stay in the run. As a Spark you can guide teammates, open doors and chests, pull levers, and possess another vessel to get a body back, but the Spark has its own draining life bar, and if every player spark is drained the run ends and the loot is lost.
