Rain World is not your typical platformer. It features a complex, procedurally animated ecosystem where every creature has its own AI, goals, and fears. You are a slugcat, separated from your family by a devastating flood. To survive, you must hunt small prey while avoiding the jaws of cunning predators like lizards, vultures, and spiders.
By purchasing a Rain World digital key, you enter a world that doesn't care about your survival. You must learn the behaviors of the local wildlife, master the physics-based movement, and manage your "Karma" to unlock gates to new regions. With the Rain World: Remix update now included in the base game, players can customize their experience with accessibility options, quality-of-life tweaks, and new tutorials. Check our price comparison table to find the cheapest keys and start your journey through the ruins today.
