Quake II

Quake II, released on December 9, 1997, is a first-person shooter computer game developed by id Software and distributed by Activision. It is not a sequel to Quake; it merely uses the name of the former game due to id's difficulties in acquiring a trademark for alternative titles.The soundtrack for Quake II was mainly provided by Sonic Mayhem, with some additional tracks by Bill Brown.
Quake II takes place in a science fiction environment. In the single-player game, the player assumes the role of a Marine named Bitterman taking part in "Operation Alien Overlord", a desperate attempt to protect Earth from alien invasion by launching a counter-attack on the home planet of the hostile cybernetic Strogg civilization. Most of the other soldiers are captured or killed almost as soon as they enter the planet's atmosphere, so it falls upon the player to penetrate the Strogg capital city alone and ultimately to assassinate the Strogg leader, the Makron.
