Damn I'm Good difficulty Steam players say typed codes do nothing on the hardest difficulty. The workaround they give is to start an episode on a lower difficulty, turn on god mode, then start a new game on Damn I'm Good. Steam Community: Duke Nukem 3D Megaton Edition cheat thread
20th Anniversary World Tour MagicGameWorld describes a cheat menu rather than typed DN codes: type DUKE on PC, or press Down, Use, Kick, Right on the D-pad and buttons on Xbox One and PS4. MagicGameWorld: Duke Nukem 3D 20th Anniversary World Tour cheats
20th Anniversary World Tour MagicGameWorld says using cheats switches off the playback feature for that game. MagicGameWorld: Duke Nukem 3D 20th Anniversary World Tour cheats
Mouse look The Steam thread says mouse look can switch off after you type a code, and that pressing U turns it back on. Steam Community: Duke Nukem 3D Megaton Edition cheat thread
