Xonotic

Xonotic is a free, open-source arena-style first-person shooter video game that emphasizes fast-paced movement, skill-based combat, and a diverse arsenal, with gameplay reminiscent of classic shooters like Quake and Unreal Tournament. Born as a community fork of the Nexuiz project to preserve open development principles, Xonotic runs on an enhanced version of the DarkPlaces engine and supports Windows, macOS, and Linux platforms with no installation required beyond extracting the game files. Players can enjoy a wide variety of multiplayer game modes—from traditional deathmatch and team captures to experimental variations like Nexball and Freeze Tag—each designed to exploit high mobility and deep map knowledge. The game includes dozens of official and community-created maps, robust server browsing, customizable HUD and controls, and even an integrated statistics system called XonStat for tracking performance.
