"The Quake 4 story picks up where Quake 2 left off, with the Space Marines fighting the Strogg, this time on the enemy's home planet, Stroggos. You'll take the role of Corporal Kane as the Marines attempt to basically annihilating their Borg-like nemesis. You'll crash land in the middle of trench warfare, and it's off to the races as one superior officer after another sends you off to retrieve people, destroy key locations, and infiltrate deep behind enemy lines. Sometimes you'll be accompanied by game-controlled team members -- typically a technical officer who can repair your armor, and/or a corpsman who can heal you up to full health. you and talks about how he’s seen you his dreams and how great things will happen to you."
