Unlike its predecessors, "Quake III Arena" does not have a plot-based single-player campaign. Instead, it simulates the multiplayer experience with computer-controlled players known as bots. The game's story is brief: "the greatest warriors of all time fight for the amusement of a race called the Vadrigar in the Arena Eternal." The introduction video shows the abduction of such a warrior, Sarge, while making a last stand. Continuity with prior games in the "Quake" series and even "Doom" is maintained by the inclusion of player models and biographical information. A familiar mixture of gothic and technological map architecture as well as specific equipment is included, such as the Quad Damage power-up, the rocket launcher, and the BFG.
