Star Trek Generations: Beyond the Nexus was a video game based on Star Trek: The Next Generation. The Game Gear version was exclusive to North America.

Gameplay consisted of the player using Captain Kirk or Captain Picard to solve various missions. There were three mission types: Ship, Away Team, and Puzzle.

Ship missions consisted of either combat from the bridge of the USS Enterprise-B or USS Enterprise-D. Both ships encountered Tholians, Romulans, and Klingons in combat.

Another type of ship missions consisted of navigating either Enterprise through rectangles in order to reach a desired destination to advance in the search of Dr. Tolian Soran.

Away Team missions featured a top-down perspective with the ability to fire a phaser at enemy forces.

The game also featured two puzzle modes. The objectives of the games were to decode a frequency and reroute power from one system to another system.
