Team Fortress (TF or QWTF/Quakeworld TF for this specific version) was a popular multiplayer modification for id Software's "Quake". It featured teams of players choosing from 9 different classes in matches of capture the flag, VIP escort, territorial control, and many other missions.

Team Fortress 1.0 was released July 25th, 1996 for the original Quake, and the first release for QuakeWorld (v2.0) came on December 22, 1996 taking advantage of the enhanced multiplayer functionality of the new client.

It was sufficiently successful that the developers formed TeamFortress Software to then develop "Team Fortress 2" as a commercial mod for Quake II. TF would instead be rewritten for the Half-Life engine.

Over ten years later, TF still enjoys a small community of active players, and several variations on the original TF formula have helped keep peoples interest, including CustomTF, which introduced the ability to configure your own custom class by trading frags scored as cash to purchase abilities.
