Stands for Team Fortress Classic, an online gaming mod for Half-Life. Teams are typically made up of players from nine classes (scout, sniper, soldier, demo man, heavy-weapons guy, pyro, medic, engineer and spy), and are pitted against each other in various missions, from capture-the-flag to eliminate-the-hunted.

Everything about the game is ancient, yet its replayability, fun factor, and absolute insanity are undeniable. TFC is a refreshing change from such 'serious' mods as Counter-Strike and Day of Defeat.

Team Fortress Classic is the 1999 update to the popular 1996 mod for Quake. It launched Half-Life's multiplayer features into the stratosphere, complimenting the amazing single-player experience with an equally superb multiplayer one. Some see it as a stop gap until Team Fortress 2, others as a testing ground to try new features which may or may not appear in this long awaited title. Others simply play it for what it is. Either way, it too is a hugely enjoyable mod with a healthy number of supportive servers and the backing of Valve Software.
