▶ Grain Rot Launch Trailer — watch on SteamWhat Is GRAIN ROT?
You are a living spark inhabiting a fragile wooden vessel. Vessels crack, collapse and catch fire, and when yours breaks the spark escapes — death is a change of housing, not an ending.
You ride a cursed elevator down into shifting ruins with your group, rip out furniture for resources, feed scrap to the Grinder for coins, and try to get back up before the Corrupted close in. If every vessel in the party breaks, everything you gathered is lost.
What you carry home rebuilds the Outpost: interactive furniture, stat upgrades, rescued survivors, and stranger tools for surviving the next descent.

Latest Updates
- October 2026 — planned
The Halloween Update
The developers' roadmap says it will open the third floor of the Outpost and introduce a new questline, plus seasonal visuals. Stated as a monthly goal, not a fixed date.
- September 2026 — planned
The Deep Layers Update
One new biome and several new enemies, described as the first major post-launch content update. Also a monthly goal rather than a date.
- Within a month of 12 Aug — planned
New constructs and a new vessel
A batch of new constructs plus one new vessel, ahead of the two larger seasonal updates.
- 12 Aug 2026
Patch 1.07 — public servers
Public servers are joinable through an in-game browser, servers can be password protected, and friends-only lobbies now admit the friends of anyone in the server, not just the host's.
- 11 Aug 2026
Patch 1.06 — Quill stops burning
Quill no longer catches fire on his patrol route outside the Outpost, and legendary gumballs that gave no reward were fixed.
- 10 Aug 2026
Patch 1.04 — lobby settings and safe balconies
Added lobby privacy and max player count settings plus a kick/ban menu, and fixed Vessels taking fire damage on balconies — which makes older umbrella guides out of date.
- 9 Aug 2026
Patch 1.03 — bunker doors
The bunker door in the ancient facilities that could not be opened by clients was fixed, along with saves loading into a black void.

The Core Loop in 60 Seconds
- 01Gather enough coins to run the elevator, then descend with your group.
- 02Read the elevator's modifier symbols — they set the rules for that run and you cannot pick them.
- 03Break furniture for resources, or feed it into the Grinder for coins.
- 04Avoid or fight the Corrupted. The deeper you go, the worse the corruption gets.
- 05If your vessel breaks you continue as a spark — find another body before your light runs out.
- 06Extract before the party wipes, or lose everything you collected.
- 07Spend the haul on Outpost rooms. Room upgrades are where permanent stats come from — character level is not.

Beginner guide
The vessel rule that ends runs instantly, what to strip on day one, and the mistakes that cost you weapons.
How many players?
Patch 1.04 added a max player count setting. Five-player lobbies are confirmed — and the usual "four" is a guess.
Outpost room upgrades
The Shop caps at 10, the Basement at 5, and your starter furniture is worth nothing until you break it.
Ancient Secrets
Ten to collect. If you are stuck on 9/10, it is the second door inside the vault.

1Frequently Asked Questions
What kind of game is GRAIN ROT?
A horror co-op extraction builder. You descend into procedurally generated ruins, scavenge, and rebuild a persistent Outpost between runs.
How many players can join?
Patch 1.04 added an in-game max player count setting, but no maximum has ever been published. A player reported a working five-person session; guides claiming a hard limit of four are repeating a guess made from marketing screenshots.
What happens when you die?
Your vessel breaks and you continue as a spark, which must find a new body before its light fades. If every vessel in the party is destroyed, the run's loot is lost.
Does levelling my character make me stronger?
No. Character level only unlocks badges for your Scrappie — pure cosmetics. Stats come from upgrading Outpost rooms.
Can the third floor be unlocked?
Not yet. The developers' public roadmap says the October Halloween update will open the third floor of the Outpost and add a new questline — stated as a monthly goal rather than a fixed date.
What is the umbrella for?
Sunlight. Without one you catch fire within a few steps of leaving the Outpost. There is a free umbrella on a second-floor balcony, and the shop sells them.
Who made GRAIN ROT and what does it cost?
Developed by Beck & Branch Games, published by Neem Interactive, released 7 August 2026 on Steam at $8.99. The developers describe themselves as a two-person team.
Ready for your first descent?
Run the tutorial first, then read the extraction page before you go below the Outpost — a small vessel cannot pick up a fuse, and that is what strands most groups on their first run.
