Star Trek: The Rebel Universe

Star Trek: The Rebel Universe presents a scenario where a mutiny within the Federation is spreading in the Sagittarius Arm, with starships defecting to the Klingons. Starfleet's contingency plan involves isolating the entire region permanently with a Klein Sphere. The player commands the Enterprise on a final investigative mission before this seal is finalized, aiming to uncover the cause of the defections and prevent a wider conflict.

Gameplay integrates graphical adventure elements with real-time starship combat and navigation. Progress is achieved by traveling to different planets, beaming down to their surfaces, and collecting items discovered there. The design allows for multiple potential resolutions to the central mystery, with necessary clues distributed throughout the journey.

The mission's outcome directly influences the narrative conclusion. Success prevents the permanent deployment of the Klein Sphere and averts a potential war, while failure results in the region's permanent isolation.
