Star Trek: THE REBEL UNIVERSE is a challenging strategy game where Starfleet Command is trying to contain a rapidly growing Federation mutiny in the Sagittarius Arm. Every Federation starship that discovers the nature of the problem has also joined the Klingons, and it's up to the player to find out what's happening before it spreads.
The Enterprise is sent on a five-year mission to discover the cause of the defections and stop them. If the player fails, the entire area will be sealed off in a Klein Sphere, potentially leading to war with the Romulans. However, if the player succeeds, the Sphere will be dropped, avoiding a catastrophic conflict.
The game is an engaging combination of graphical adventure, real-time combat, and piloting. The player must fly to planets, beam down to investigate, and retrieve any items they find. Along the way, clues are revealed that can help or hinder progress.
