I've been wanting a proper zombie infection mod for this game, and I really hope someone would understand. With people re-uploading/stealing other mods, it is hard to find a good zombie infection mod.
Edit: I think it would be better if there was a way to create said zombie infection, via a scientific way. And maybe give the infected some mutations (that can either be spawned, or created after being infected.) and maybe through the same process, create a cure/vaccine.
