It was a Star Trek FPS before Elite Force, using the Unreal 1 engine, where you play as a Klingon elite force member with some interesting weapons such as wrist mounted disc launcher. I hope GOG can add non-Activision ST games, since it was published by Microprose.
Rights to Microprose titles are not a mess, they're a nuclear disaster zone. According to this hour-long game post-mortem
for Birth of the Federation that was also a MPS Trek game, the community tried to track down who even has the rights and/or source code for the game. The latter is most likely lost, and if the former is not in a dusty Atari archive, the games are in a VERY deep copyright hell.
