The game starts with a view from a window of an orbiting craft, observing a flyer down in
Jupiter's atmosphere. The "Jupiter Flyer" appears to encounter a problem, leading to the death of all the crew members aboard. The player (commander) watches this from said orbiter. After this, he returns to
Earth alone, only to find that hours later,
Earth received an alien signal giving instructions on how to build a spacecraft: Exo One. The player claims the signal was meant for them, but the people in charge of the craft wouldn't allow the player to pilot Exo One due to the player's mental state. Someone else ends up piloting the ship, and it fails to launch. The player repeats the claim that Exo One only works with him. An informant ends up telling the player that the spacecraft is stored in a hangar in a desert, so the player steals said craft and starts to travel across planets using alien technology in order to try to bring the original "Jupiter Flyer" crew back. In the end of the game, an orange light creates a
space-time singularity, which the player utilizes to travel back in time to where the "Jupiter Flyer" disaster happened. After allowing the crew to survive, you stay on
Jupiter with Exo One, and the players fate is undecided. == Development==
