Cube was early on one of the first open-source first-person shooter games designed around its own engine. The 3D graphics for Cube were not the best, but development of this game had been going on since 2001. Based upon the Cube engine was then the Sauerbraten game that was also referred to as "Cube 2" with its engine being redesigned. Now though another game is emerging and its engine is derived from Sauerbraten. This game is called Blood Frontier and in this article we have a few screenshots of this game, which is working its way towards a stable release for the open-source community.
Blood Frontier is based upon the Sauerbraten engine and takes advantage of the features like a 6-direction height field world model, real-time map editing, light-maps, shader-based lighting effects, integrated physics support, and a particle engine. Like Cube and Cube 2, Blood Frontier uses OpenGL and SDL, which makes it multi-platform friendly with binaries for Windows, Linux, and Mac OS X.
While based upon the Sauerbraten engine, all of the artwork for this game is original and is geared around a space/futuristic theme. The artwork is okay and about normal quality for open-source games, but not quite as nice as Nexuiz and could certainly be improved. With the development release of Blood Frontier that we were testing, there were just seven maps available.
