Evaluation
Exo One: Prologue is a free standalone demo released on August 21, 2020, designed as a short (~10 minute) introduction to the mechanics and atmosphere of the full game, Exo One. The store description explicitly frames it as a prologue and preview for the main game. The full game, Exo One, launched on November 18, 2021, as confirmed by a developer post celebrating its release. The prologue itself is a self-contained, intentionally short sampler — it shipped complete by design and was never intended to receive its own ongoing content. With the main game now released, the prologue has fully served its purpose. No further updates, DLC, or content additions have been announced or are expected for this title.

This is a short first taste of Exo One - approximately 10 mins playing time
A strange signal... an alien craft... an interplanetary, gravity-defying journey through space and time.
On the anniversary of the Jupiter accident, an alien signal transmits construction blueprints for an alien craft, which humanity builds, called Exo One.
Master a truly alien traversal system and move through enigmatic and desolate alien landscapes in ways you've never experienced. Use gravity and momentum to reach colossal speeds and exhilarating heights.
Ride thermal updrafts into boiling cloud formations, careen down hillsides and launch off mountain tops, all the time drifting toward the shining blue beam on the horizon. Atmospheric, diffused visuals are merged with otherworldly sound effects and a hypnotic electric guitar soundtrack.
Pilot your craft on mankind's first voyage outside the solar system, and go on an interplanetary journey across space and time.
