Loopr Partners and developer Twin Beacon Studio announced the co-op adventure game All Rats on Deck for PC via Steam in Q4 2026. Players control rats driven from their swamp home who pilot a steamboat built from scrap toward the open sea. The game supports online co-op for up to four players and includes proximity voice chat. Crews split tasks: steering, repairing damage, fighting fires, and gathering materials. The ship carries a detachable boat grapple gun that can pull the vessel toward fixed objects, grab distant materials, pick up friends, or move rocks and activate mechanisms. Fuel must be fed continuously to the engine, and the game allows anything to be used as fuel, though some materials cause side effects or explosions. Twin Beacon Studio is a Netherlands-based indie studio founded in February 2026, and All Rats on Deck is its first game. A demo is planned for Steam Next Fest in October 2026. As of the store page, the game does not list Japanese among its supported languages.
Development began with the "Friendslop" trend in mind, according to Automaton. The game lets players throw materials at frogs that prey on rats and includes a stamina gauge, rat appearance customization, and emotes.
The Steam store page lists all of the following as key features:
- 4-player co-op: team up with three friends
- Maintain and pilot the steamboat: run a makeshift ship through the swamp
- Resourceful rat crew: pick up whatever you find and put it to use
- Anything can fuel the engine: throw random items in to move the ship
- Explore dangerous waters: avoid obstacles and unpredictable environments
- Grapple gun: mounted on the ship to help with movement
- Proximity voice chat: talk with friends when together or apart
- Chaotic co-op experience: improvise solutions to problems
Twin Beacon Studio is based in the Netherlands and was founded in February 2026. According to LinkedIn, four students majoring in game technology are developing it. Loopr Partners announced the game on September 29 and opened the store page alongside a trailer, though Denfaminicogamer gives the date as September 28.
