theres also other stuff like uhh more powerful shotguns and a chaingun (also gibbable corpses like quake 2 this was from a tutorial by wazat) 

Hey hooberserenity, fun mod! I enjoyed the interaction between the gibbable corpses and the BFG effect.

I had a little play around with your BFG model as an exercise to keep my skills sharp. I set myself the goal of compacting the skin down to a 256x256 size (because skins with power-of-two dimensions are sharper in early GLQuake engines and waste less texture memory in more modern ports).

The resulting model is uploaded at
