Play Star Trek: The Rebel Universe Online

Star Trek: The Rebel Universe is a graphical adventure game released in 1988 for the MS-DOS platform. Published by Simon & Schuster Interactive, the game is set within the Star Trek universe and is presented from a third-person perspective. The narrative centers on a crisis in the Sagittarius Arm, where numerous Federation starships have mutinied and allied with the Klingon Empire.

Players assume command of the starship Enterprise, dispatched by Starfleet on a critical five-year mission. The primary objective is to investigate the cause of the widespread defections before a permanent containment field, known as a Klein Sphere, is activated to seal off the entire region. Progression involves navigating the starship to various planets, beaming down to their surfaces, and exploring environments to retrieve items and gather clues. The gameplay integrates real-time elements for piloting the ship and managing combat encounters with hostile vessels.

The structure allows for multiple potential solutions to the central mystery, determined by the clues and items collected during exploration. Success in the mission prevents the permanent deployment of the Klein Sphere and averts a potential conflict with the Romulan Empire, while failure results in the region's permanent isolation. The experience combines point-and-click adventure mechanics with sequences of starship command and interstellar travel.
