Destructable Doors?

I was woundering if somebody could make a destructable door tool where it has certin health and zombies can break them down and parts fall off them like in l4d? or can you send me a link to one that already exists? you could also have an option to turn existing doors to destructable ones it would be really cool, please try to make one, or even find out if its possable :stuck_out_tongue:

zombies have a hard time destroying boxes if you have a door they will never find you. Just an opinion
