About Proteus
Proteus is a first-person exploration game set on procedurally generated islands. You explore by moving through the world and observing it; your presence and surroundings create the soundtrack. The islands contain natural and imagined creatures, tranquil valleys and ruins with magical properties.
Explore the islands
The world offers no text or hints, leaving you to investigate at your own pace. Its responsive surroundings reward patience and immersion. Each island is generated uniquely, and while it is theoretically possible to see everything in one playthrough, no one ever does.
Sound and style
A dynamic soundtrack composed by David Kanaga follows the mood of the world. The graphics combine 2D and 3D elements, with shifting palettes that draw on 8-bit video games and early 20th-century modernist painting.
Save and share discoveries
The built-in postcard function encodes world data into each screenshot, letting you save and share islands and discoveries.
