The cooperative horror action game GRAIN ROT launched on Steam on August 8, 2026, with support for Japanese. Developed by Beck & Branch Games and published by Neem Interactive, the game is priced at 1,150 yen including tax, with a 10% launch discount to 1,035 yen until August 22. Players descend into underground ruins via a cursed elevator, break furniture to collect resources, and aim to return alive. The loot is used to rebuild a forward operating base, which in turn allows deeper dives into the ruins. The game has drawn significant pre-release attention: Steam wishlist registrations exceeded 250,000, and the demo download count surpassed 350,000, placing it among the top 15 most played titles during Steam Next Fest. In gameplay, players possess fragile wooden robots; if a robot breaks, they can find another in the darkness to revive, with abilities changing based on the machine. Deeper floors introduce 'corruption' that distorts bodies, voices, and emotes, and corrupted machines react to sound and movement. If all party members' robots are destroyed, all loot is lost. The game supports both single-player and online cooperative play on PC via Steam.
- Dropkicking enemies is possible, but the physics engine also lets players "accidentally" eject a companion's soul from their machine.
- Accidents include trapping companions in corridors swarming with monsters or hitting them with stray bullets during gunfights.
- Players can run into grinders to earn gold, a resource separate from the furniture collected for base rebuilding.
- If a player's machine breaks and no replacement is found in the darkness before time runs out, they disappear permanently.
- The official launch announcement on X (formerly Twitter) from the GRAIN ROT account on August 7, 2026, confirmed the $8.99 launch price with a 10% discount.
- The game's core loop is described as a cycle: dive into ruins, bring back supplies, rebuild the forward operating base, and use the improved base to dive deeper.
- Corrupted machines in deeper floors react not only to sound and movement but also to each other, making outcomes unpredictable.
- The developer's announcement thanked players who joined during the pre-launch period, referring to them as "Scrappies."
