The Duke Burger is the 12th level in Duke Nukem Forever. After hijacking an Assult Trooper Captain's jetpack, Duke crash-lands into the Duke Burger. The player must navigate the resturant, mostly shrunk.

The first part is very short and will not take too much of your time.

The mission is split into two more parts;

The Duke Burger: Part 2 and...

The Duke Burger: Part 3
