While down in the sewer performing repair work you noticed some shadows. You quickly realize that the way back out is blocked, and go down further below. And you urgently need weapons. There are many weapons in the basements, but they are old. Grabbing a gun you immediately shot at the first monster. Hooray! Monsters can be killed. Now start looking for more ammunition and a way back to the surface.
