Sauerbraten (a.k.a. Cube 2) is a free multiplayer/singleplayer first person shooter, built as a major redesign of the Cube FPS.
Much like the original Cube, the aim of this game is not necessarily to produce the most features & eyecandy possible, but ather to allow map/geometry editing to be done dynamically in-game, to create fun gameplay and an elegant engine.
