Lighthouse

About

How many Pigcops does it take to stop Duke from screwing in a light bulb? You probably know the answer. It is dawn. Duke is sent to repair a lighthouse overrun by aliens. A hard climb to the base of the tower, and Duke finds there are eight floors to the top , and the elevator is locked. Some pigcops have learned to toss morters, some turrets have been upgraded to RPG launchers, and Duke is thinking he will be putting in some overtime on this job.
