Duke Nukem 3D: 20th Anniversary World Tour

An easy way to get this is on the last level of Episode 3, ‘Stadium.’ Play on the “Piece of Cake” difficulty and there is only one enemy, the Cycloid Emperor. As you take the lift up to the stadium, activate the cheat menu and select ‘Give All’ and turn ‘God Mode’ on, defeat the boss and the achievement will unlock.

NOTE: If this is the first time playing this level, you will also unlock “Come Get Some.”
