"SOURCE CODE
The compilable source code is included as well as all textures, models, and scripts. There's even some unused stuff in there. Please feel free to use any of it in any manner you like. The code is annotated to help you understand it faster. We made this for you as players and developers to use so when you get done throwing broc bombs and fork stabbing you are totally invited to use/improve/change as you see fit. You might add credit lines if you use the models or textures but the code can be freely used without credit. I'll know it when I see it and honestly when that happens it's one of the most thrilling things you get to experience as a dev."
