Cocoon is a puzzle adventure game developed by Geometric Interactive and published by Annapurna Interactive. Players control a small insect-like creature navigating interconnected worlds contained within orbs, solving environmental puzzles by carrying and using these orbs to manipulate space and progression.

Players have to interact with alien environments and biomechanical devices left behind by an ancient civilization. They journey through unique and diverse biomes, from industrial structures to massive organic caverns, and discover how they are connected to one another. Each orb has an ability that can be unlocked, thereby turning the orb into a unique tool for players to utilize within other worlds. Players can use these abilities to uncover hidden pathways and objects, fire projectiles to trigger switches, and more.
