About the game
You and your friends try to escape a space waterpark after its guests turn into zombies. The planned game puts your supplies and workbenches on a raft assembled from inner tubes. You add walls, sails and engines, but the weight and balance of each addition affect how the raft moves. Water guns and pool noodles keep enemies away as you follow the river toward an exit.
Online teams support up to four players. Someone can guard the raft while others search the shore for materials, then everyone has to catch up before it drifts away. Food, repairs and security blockades compete for your attention. Early hands-on accounts describe hurried resource gathering and boats coming apart under attack. Steam Early Access is planned for summer 2027, so these details describe the announced design and preview builds.
