/cocg/ was disbanded because Savin constantly brigaded the general with his shit and every Anon despises Savin, so figure why the general died (also add the the general went into halfchan /vg/ instead going to /h/).
About the modding:
As I said before, to mod this crapheap of a game, you need to create a framework and reverse engineer the spaghetti code of a game that is being made by the devs. Then recompile and make modules that can bake any changes instead of hardcode into the framework. (basically you need to create a game engine from scratch)
