Quake III: Team Arena, or simply Team Arena (TA) is an official mod for Quake III Arena, released by id Software itself. Unlike most mods, it is not free of charge, but it is a commercial software instead. The Demo version includes only one map and is a standalone game. The full version, instead, needs Quake III Arena to work. It is also possible to buy it in a single package together with the standard Quake III, as Quake III Gold.
