August 7, 2026 — GRAIN ROT, the mega-viral co-op extraction horror from indie duo Beck & Branch Games and publisher Neem Interactive, is out now on Windows PC via Steam for $9.99, discounted 10% to $8.99 for launch week.
If you've lost a friendship to R.E.P.O. or Lethal Company, you already know the shape of it: four friends, one dark hole, and a loot quota that turns allies into liabilities. GRAIN ROT takes that and gives it a body count that doesn't stick, a home that remembers, and a world that is actively, visibly rotting.
The game arrives as one of the notable indie runs of the year: more than 350,000 demo downloads, a Top 15 most-played demo at Steam Next Fest, and #1 trending gameplay on YouTube (from the creator SMii7Y).

You are the light inside. You play a Living Spark - an artificial soul riding a fragile wooden vessel through a world where the surface is gone and anything left exposed eventually catches fire. Burn up or get smashed to splinters and the run doesn't end; your Spark goes looking for a new body, and keeps looking, right up until the final extraction. Death is a formality. It's also how your friends steal your legs.
The Outpost is the point. Every crew works out of the Sanctuary Outpost, a crumbling high-rise held together by two brothers - Biggie and Murch - and whatever you drag back up the elevator. Loot doesn't just score the run; it rebuilds the place, and what you rebuild determines what you can carry down next time. Progression lives as much in the hours between runs as in the runs themselves. Lose it all down there and the Outpost feels it.
Every descent is a different building. Beneath the Outpost, the Deep Layers reshape themselves each trip. Loot rarity turns extraction into an actual risk-versus-reward call rather than a grab-everything scramble. Watch for the Corrupted - vessels that lost their Sparks, or didn't lose them completely - moving through the halls and reacting to sound, movement, and sometimes each other in ways that are hard to read until it's far too late.
A rot that sinks deeper. The further down you go, the less certain anything gets. Sound and voice distort as the Rot spreads, bodies pick up corruption and mutation, and something as small as an emote turns unsettling. It's a world where the ruins and the vessels are both decaying from the inside, lit by firelight that feels earned rather than decorative.
Tactical carpentry, applied badly. Furniture is loot, cover, building material, and currency. Smash a wardrobe for resources, feed the debris to the Grinder for gold, or leave it standing between you and whatever's coming. Dropkick anything not nailed down. Knock a friend's Spark clean out of their vessel with a cursed emote and see how the crew handles it - but troll wisely: if everyone breaks, the loot is gone for good.
