the door must be closed...

This door needs to be closed! why is it open! it is not to keep things out, it is used to keep things in... last year, we had a failed expirement, we didnt know at first, but it killed ten of our men, before we contained it. We injected one of the armys soldiers with a serium, it was supposed to make him into a super soldier, but the soldier went to a zombie type state. then we put him into confinement, until you opened the dang door!! now the soldier is going to DESTROY US ALL!!!
