What Is
GRAIN ROT?
GRAIN ROT is a horror co-op extraction builder developed by Beck & Branch Games and published by Neem Interactive. Players ride a cursed elevator into shifting underground ruins, dismantle furniture, collect loot, evade the Corrupted, and return to rebuild their Outpost.
You play as a Living Spark inside a fragile wooden vessel. When that vessel breaks, the Spark remains in the run and must find another host before fading, while successfully extracted resources provide permanent Outpost progression.
