Star Trek: 25th Anniversary is a point & click adventure game released in 1992 for DOS. It features the original Star Trek crew (Kirk, Spock, McCoy and redshirt). You play through seven episodes, each assigning you with a mission that you need to complete in order to go on with the next mission.

MUGG completes the seven missions of the floppy release (since it features a much shorter mission 7) in record time.
