This mod is focused around the BFG weapon. But it is not the BFG10K from Quake 3/OpenArena, it is the BFG10K from Quake 2, a very different weapon. This BFG consumes 50 cells at each use, has a long recharge time and also a pre-load time before shooting. It will shoot a huge green energy ball that will slowly fly across the air. If there are enemies in the area, they will be hit by automatic "laser beams" emitted by the energy ball. The ball explodes when hits someone or something. You will find a readme.txt file in the mod's folder.
