How co-op works
Online co-op teams explore procedurally generated ruins to strip furniture, gather loot, and extract before enemies or environmental hazards force a retreat. Salvaged materials upgrade a persistent Outpost that unlocks tools and access to more dangerous zones.
About this game
GRAIN ROT is a horror extraction builder set in a wasteland where fire consumes everything and survival hinges on coordinated scavenging runs. Squads descend into shifting ruins, tear furniture from the walls, and haul back whatever they can carry before the Corrupted appear or the structure collapses. Each expedition tests speed, planning, and the group's ability to adapt when threats escalate.

Moment-to-moment play revolves around splitting tasks: one player searches rooms, another defends a chokepoint, a third drags a heavy cabinet toward the exit. Stamina, inventory limits, and randomized layouts force constant communication. Hazards compound as the clock runs down, and escape routes narrow the longer the team lingers.
Between runs, survivors rebuild the Outpost using scavenged materials. Upgrades improve tools, reinforce defenses, and unlock access to deeper, more lucrative zones. Each successful extraction feeds the next, creating a risk-reward loop that scales difficulty alongside the squad's growing capabilities and willingness to push further into the ruins.

Frequently Asked Questions
How many players can team up in co-op?
GRAIN ROT supports online co-op, though the exact player count isn't specified on the store page. The game is built around squad-based runs where teammates split tasks like scavenging, defending, and hauling loot, so expect small-team coordination.
Do we need voice chat or good communication to play together?
Yes. The game revolves around dividing roles on the fly-one player searching rooms, another watching a chokepoint, someone else dragging heavy furniture. Stamina limits, randomized layouts, and time pressure mean you'll constantly need to call out hazards, coordinate extractions, and adapt plans as threats escalate.
What happens to our progress if we don't make it out alive?
If your squad fails to extract, you lose whatever loot you were carrying that run. Only materials you successfully bring back to the Outpost count toward upgrades, so each expedition is a risk-reward decision about when to bail versus push deeper for better salvage.
Can I play GRAIN ROT solo, or is it co-op only?
The game supports single-player as well as co-op, so you can tackle runs alone. However, the design clearly emphasizes teamwork-splitting tasks, covering each other, and coordinating extractions-so solo play will be significantly more challenging.
