In mid-April, Steam will be releasing a mammoth free update for the ultra-popular Team Fortress 2 game. Included in the update are new weapons for Medic class players, and new Achievements, and equipment for all classes. Also, all player classes will eventually get new unlockable weapons. There's a catch though - to unlock these new features, you'll have to complete 12 of 36 new Achievements. Then, there's Goldrush - the new map for all classes that will be the first map for a new game mode called "Payload". In Payload, the Blue team needs to guide a cart of explosives to the Red team base. Payload will also be the first TF2 map to take advantage of the cinematic physics technology from Half-Life 2.
