The Quake legend grows with the fourth release of this storied shooter. Victory is the only option in an epic invasion of a barbaric planet. But in order to defeat the Strogg, you have to become one of them. Begin the game as an elite marine. After you're captured, re-enter the fray as a "Stroggified" marine with enhanced capabilities. Fight in small-squad missions and in full-scale blitzkriegs that rage across indoor and outdoor battlegrounds. You've got the most advanced weaponry possible with plenty of available modifications, and futuristic vehicles including mechanized walkers and hover tanks. Arena-style multiplayer allows play as Strogg or marine in Deathmatch, Team Deathmatch, and Capture-the-Flag Modes.
