A couple of times I've been generated a room that technically has an exit, but no way to reach it. Typically, it is blocked by a stone wall which cannot be broken by the rocket launcher, and there are no barrels in the room.
There is a weapon reload mod lying here.
There is a blue armor [2/2] (100%) lying here.
