Smashed Lab

Here is where the teleportation leaves you. The lab is a large building containing three rooms. There used to be a top floor, but the stairs to it have been destroyed, and who knows if it still exists. There are also a coupl of doors that lead to what is presumably a basement area, but they are locked. The door that leads out into the wilds of Outer Island is also locked. How are you going to get out of here?
