Lazy River is an upcoming co-op survival shooter set in a whimsical space waterpark named Water Station One. The game features a lazy river where players, along with up to three friends, must survive against zombie guests who transform when someone pees in the pool. The unique mechanics revolve around the special properties of space water, which causes this transformation. Players will utilize water balloons, squirt guns, and pool noodles to fend off the zombies, who explode when wet. To escape the park, players need to build and upgrade rafts using inner tubes and various materials, ensuring the raft remains balanced while avoiding robot security teams and alarms that could trigger a self-cleaning process. Developed by Mike Boxleiter, known for his work on Secret Hitler and other titles, Lazy River has been in development for four years and is set to launch in early access on Steam in summer 2027 for $20.
