Dam Top is the 16th chapter of Duke Nukem Forever.
Duke meets with EDF soldiers on top of the Hoover Dam, and together, they fight their way through alien forces. Once they reach the end of the dam, they are ambushed by a resurgent Battlelord, and a boss fight commences.
After the Battlelord is defeated for the last time, Duke rappels down to the bottom of the dam. He makes his way to a door for maintenance personnel.
