Quake 4

Quake 4 has a stronger emphasis on single-player than its predecessor, which emphasizes multiplayer gameplay, and features a campaign that continues the story of Quake II. The Quake 4 single player mode continues the story of Quake II by pitting the player against cyborg alien race known as the Strogg. The game follows the story of a Marine Corporal named Matthew Kane who is joining the elite Rhino Squad. Following the success of the protagonist of Quake II in destroying the Strogg's leader, the Makron, Rhino Squad is tasked with spearheading the mission to secure the aliens' home planet Stroggos.
