Xonotic

The game runs on a heavily modified version of the Quake engine known as DarkPlaces engine. Emphasis is placed on movement and player physics, with a focus on gaining speed, jumping great distances, and conquering the level geometry. The game runs on the DarkPlaces engine and thus supports bloom, dynamic lighting and shadowing, offset mapping, and high dynamic range rendering. The original creator, Lee Vermeulen, secretly made a deal with a company known as Illfonic according to which the latter got the hold over the Nexuiz trademark. It comes with sRGB lightmap rendering, a new menu interface, 4 new maps, an integrated statistics system , a Sandbox editing mode and the long-awaited feature of ClientSide QuakeC networked players. It features client-side rendering of players, 4 new maps and a complete re-write of the in-game chat system.
