Formerly known as Cube, Sauerbraten is an open-source first person shooter game built upon the Cube engine that has been entertaining gamers for years. Sauerbraten has come along way when it comes to advanced rendering features, maps / game-play modes, and other features, with a sign of these improvements being the Sauerbraten 2008-06-17 CTF Edition release. As implied by its name, this most recent release of Sauerbraten introduces a capture the flag game-mode. In addition to the CTF gaming support, there are many other improvements and new features, with this being the first update since the end of 2007.
Impressive release. Great game, and their own engine is also quiet good! I am wondering what the open source engines will be able to with OpenGL 3, if it ever comes out... anyone knows what's delaying it?
