"Rain World is a challenging Metroidvania-style platformer from Videocult and Akupara Games. In Rain World, players contr ol a vulnerable but nimble "slugcat" as it struggles to survive in a strange and dangerous world. Until now, the only way to brave the game's rain-soaked world was solo, but the Rain World: Downpour DLC, which has just come to consoles following the PC release, changes all that. The 'Downpour' DLC adds 4-player local co-op support, five new playable characters, and more," says Co-Optimus.
