with zombie hordes comming soon i think the sneak engine needs a bit of a tweek right now if you sneak into a house they still see/hear you and rush in threw doors and walls , you should be able to sneak past if your quiet , and zombies shouldnt be able to run threw doors. Now if simply closing the door behind you is to easy maybe add somerthing like Padlocks that can be found and can be used on doors but players can still axe them open .... just an idea for alpha i do think we need more zombies though
