After exiting the Lady Killer Casino, Duke meets up with Dylan and several EDF soldiers. After receiving the Ripper (and rejecting Master Chief armor) from a truck, Duke mounts a turret and mows down several Aliens. After making his way through the ruined Las Vegas, Duke meets up with more EDF soldiers in a pit. Duke clears the area, not long after, a Battlelord crashes through the pit wall. A battle insues, ending with Duke punching the Battlelord "Right in the jewels" and killing him. Dylan breaks out of a sewer pipe nearby. Duke heads into the pipe, leading into The Duke Dome.
