Definately one of the more entertaining zombie slaying games out there. Feels a little more serious than Left for Dead but it distinctly lacks some of the aforementioned title's polish. Tripwire makes good games and this oen is no exception.

An oldie but still a goodie. The controls are anything BUT Call of Duty's arcade feel and have an ooh-so-right learning curve. The graphics have aged quite well as well.

From jets to jeeps this game has a lot to offer. Large maps with up to 64 players in server, expect some rediculous firefights. Squad based tactics are a must and your team (all 32 of you) really need to put forth a cohesive effort to win a round. Some of my best moments in gaming come from this game.

Give the Project Reality mod a look for an even more massive and realistic take on the game.
