Exo One is a physics-based exploration game about a strange alien orb that can transform its shape to roll, glide, and fly across vast planetary landscapes. Momentum and gravity are the core tools, letting players build speed down slopes and launch into soaring flight.

The game emphasizes meditative, open exploration over combat or puzzles, sending players across a sequence of alien worlds as they master the orb's shifting form and chase a sense of freefall and flight.
