Rain World is a 2017 survival platform game developed by Videocult and published by Adult Swim Games and Akupara Games for PlayStation 4 and Microsoft Windows in March 2017, and for Nintendo Switch in late 2018. Players assume control of the "slugcat", an elongated field-like rodent, and are tasked with survival in a derelict and hostile world. The game features a simulated ecosystem. The slugcat uses debris as weapons to escape predators, scavenges for food, and tries to reach safe hibernation rooms before the deadly torrential rain arrives. The player is given little explicit guidance on how to survive, which was the intention of the developers, who wanted players to feel like a rat living on subway tracks, in which they learn to survive in an environment without grasping its higher-level function. Rain World received mixed reviews from critics, who praised its art design and fluid animations, but criticized its brutal difficulty, inconsistent save points, and imprecise controls. Some of these criticisms were addressed with later updates. In January 2023, a downloadable content pack titled Rain World: Downpour was released for PC. Downpour was released for Switch, Playstation, and Xbox on July 11, 2023.
