The weapons are balanced by role, with each weapon having advantages in certain situations, such as the railgun at long-range and the lightning gun at close quarters. While deathmatch maps are designed for up to 16 players, tournament maps are designed for duels between 2 players and in the single-player game could be considered ' boss battles'.

As the game progresses, the fights take place in more complex arenas and against tougher opponents. In Quake III Arena, the player progresses through tiers of maps, combating different bot characters that increase in difficulty, from Crash (at Tier 0) to Xaero (at Tier 7). 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. Continuity with prior games in the Quake series and even Doom is maintained by the inclusion of player models and biographical information. 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. Instead, it simulates the multiplayer experience with computer-controlled players known as bots. Unlike its predecessors, Quake III Arena does not have a plot-based single-player campaign. Quake III Arena has also been used extensively in professional electronic sports tournaments such as QuakeCon, Cyberathlete Professional League, DreamHack, and the Electronic Sports World Cup. Many liked the crisp graphics and focus on multiplayer. The game was praised by reviewers who, for the most part, described the gameplay as fun and engaging. Notable features of Quake III Arena include the minimalist design, lacking rarely used items and features the extensive customizability of player settings such as field of view, texture detail and enemy model and advanced movement features such as strafe-jumping and rocket-jumping. It features music composed by Sonic Mayhem and Front Line Assembly founder Bill Leeb.

The single-player mode is played against computer-controlled bots. The third installment of the Quake series, Arena differs from previous games by excluding a story-based single-player mode and focusing primarily on multiplayer gameplay.

Quake III Arena is a 1999 multiplayer-focused first-person shooter developed by id Software.
