Grain Rot

Grain Rot is a co-op extraction game about a Living Spark exploring shifting underground ruins inside fragile wooden vessels. You descend with your crew in a cursed elevator, gather resources and gold, and try to bring your haul back to rebuild your Outpost. If everyone’s vessel breaks, the loot is lost.

Vessels and Sparks

Your vessel can splinter, collapse or catch fire. When it breaks, you remain in the run as a Spark, guiding your team through the dark while searching for another host with a new set of abilities. You must find a vessel before you fade away completely.

The game’s physics-driven chaos can turn against your crew: you can dropkick enemies or launch an ally’s Spark out of their vessel, while corridors and crossfire can leave teammates trapped or in danger. The Deep Layers contain Corrupted vessels that react to sound, movement and one another in unpredictable ways.

Explore the Deep Layers

The underground dungeons shift procedurally, and the Rot worsens as you descend. Bodies warp, voices distort and emotes change. You can fight, build, run or panic as you face the Corrupted and try to extract your loot.

Rebuild your Outpost

What you bring back goes toward rebuilding your persistent Outpost. You can unlock interactive furniture, stat upgrades, rescued survivors and new ways to survive future descents. A stronger Outpost lets you venture deeper.
