Sauerbraten [a.k.a. Cube 2]

Kademlia
Sauerbraten (a.k.a. Cube 2) is a free, open source, both multi & singleplayer first person shooter game. It was built as a major redesign of it's predecessor the Cube by Lee Salzman, Wouter van Oortmerssen (the original creator), Mike Dysart & Robert Pointon. Just like in the original game, the main emphasis falls not on the pretty graphics & load of functions, but on seamless and dynamic in-game map/geometry editing. In the latest version of Sauerbraten gamers playing together online can even co-edit a level at the same time.

Cube

Kademlia
This is an oldy-but-goodie. Cube was first released in singleplayer mode in January 2002 and had multiple updates all the way up to 2005. The game and its engine (which also called Cube) were developed by Wouter van Oortmerssen, a Dutch computer programmer. The game was always very well reviewed and it even received an award for "Best Free 3D Action Game" in 2003. It runs on almost all operating systems, it features both singleplayer and multiplayer gameplaya and even has a build-in level editor.
