Quake 4

Description:
Quake 4 takes you back to the front as you fight against an unrelenting alien enemy. Armed with advanced weaponry and vehicles and aided by an elite squad of marines, you take the battle to the heart of the Strogg home planet and become Earth's only hope for victory. They're regrouping but with their planetary defenses ruined, you have a chance to deliver a full and final assault. You are Matthew Kane, an elite member of Rhino Squad, and part of Earth's next invasion wave. With the Makron assumed dead, your squad is taking part in an operation to take advantage of the disarray and mop up the rest of the enemy forces on the Strogg planet. But your drop ship gets hit and comes down hard, killing a large chunk of your squadmates at the opening of the game. From there, you'll pull yourself up out of the muck and get down to business.
