Quake III Arena

About

id's released source, carried by ioquake3 to WebAssembly, with the official demo data and live servers. Pick an arena and frag.

Quake III Arena is a first-person shooter built around competitive multiplayer combat. Unlike earlier entries in the Quake series, it has no story-driven campaign, and its single-player mode instead pits the player against computer-controlled bots across a series of increasingly difficult arenas. Matches take place in maps that mix gothic and technological architecture, with weapons and power-ups spawning at fixed points that players fight to control. Movement techniques such as strafe-jumping and rocket-jumping are central to high-level play. Game modes include free-for-all deathmatch, team deathmatch, one-on-one tournament duels, and capture the flag, and the game supports network and internet play along with extensive customization and modding.
