I was thinking it would be cool if the zombies you initialy had in gmod would break down doors if its in there way and they could detect enemy and know where they are on the level. about the door one if it is posible would it be doors initialy on the level or a mod to the door tool where they could break down the wooden doors in it. Well that all so if you want to do this good luck and give me a tiny bit of creadit for the idea. Steam id is emhann.
