Duke Nukem 3D: 20th Anniversary World Tour

An easy way to get this is on the level ‘Tour De Nukem’ in Episode 5. From the start of the level, walk straight through the open door and stay to the right of the dumpster. Walk straight and at the end of the sidewalk, there will be a couple of garbage cans next to another dumpster with a pile in the right corner in front of an ATM. Step in it to unlock the achievement.
