Eco-adventure Rain World is getting a new expansion, complete with new slugcat

Rain World will get a new expansion called Rain World: The Watcher on March 28, 2025. The release will co me with a new slugcat to play as—the Watcher, AKA the Nightcat—and will be set in a wholly new-looking area of the Rain World with its own strange ecology that we get glimpses of in the released trailer.

That includes some drifting fluffy piles of what may well be snow, which is a big twist for a world with such intense downpours that they literally kill you if your poor little Slugcat if they don’t have somewhere to hide. Though perhaps Nightcat doesn’t care so much: It stands in a slight drizzle seemingly unconcerned in the trailer.
