Team Fortress 2 is the sequel to the game that put class-based, multiplayer team warfare on the map. It delivers new gametypes, a signature art style powered by Valve's next generation animation technology, persistent player statistics, and more.

Nine unique classes clearly defining purpose by way of nationality, race, mental conditions, posture, and above all: character. Epic team-focused gameplay long proven by the success of the original Quake mod and its many successors. An ever-increasing fanbase matched only by the merciless expansion of the game itself. Mac players play side-by-side with PC players with no hate (except to the enemy team, of course). If you want to get away from Counter-Strike, just 10 minutes in a good honest round of TF2 will be enough for you to start piling up hats in your inventory and having a good time on the incredible sequel to the granddaddy of class-based multiplayer action games!
