Star Trek: 25th Anniversary is an adventure video game developed and published by Interplay Productions in 1992, based on the Star Trek universe. The game chronicles various missions of James T. Kirk and his crew of the USS Enterprise. Its 1993 sequel, Star Trek: Judgment Rites, continues and concludes this two-game series, which together may be seen as the final two years of the USS Enterprise's five-year mission.
The player takes on the role of Captain James T. Kirk on board the USS Enterprise, a Starfleet vessel as seen in the American science fiction television series Star Trek: The Original Series. It is split into two main modes, a main bridge view, and a third-person mode whenever an away team is transported to a planet or space station. During several combat sequences the player controls the Enterprise in battle against enemies in space; originally required, Interplay later offered a patch making them optional. The controls on the bridge are split across the crew, with Montgomery Scott allowing access to the shield and power controls, Pavel Chekov controlling navigation, and Hikaru Sulu controlling the orbit of the ship, for example. The away team always consists of Kirk, Spock and Leonard McCoy, as well as one of eight different redshirts, many of whom can die during the mission. The player interacts with these modes using a point and click interface via the mouse.
