Duke Nukem 3D Cheat Codes: Original PC / Atomic Edition
Duke Nukem 3D’s classic PC cheats are typed during play, beginning with DN. DNSTUFF supplies equipment and keys, while DNCORNHOLIO toggles god mode. This reference is for the original PC family rather than World Tour’s separate interface.

Use cheats only in a single-player game or an authorized private session. Keep an untouched save before changing a game state. This is an independent text guide. Duke Nukem 3D is not available to play on Gamehub.
Setup and activation
- Keep a save before changing the level.
- Start or load a normal single-player game below Damn I’m Good.

Version notes and help
Select the edition first
World Tour adds its own cheat handling, and console releases have button sequences. The typed DN codes here should not be presented as universal instructions for every Duke release. Atomic Edition also has an extra episode that the original three-episode game lacks.
Treat noclip as a temporary tool
Original releases can punish movement into empty space. Even a version that tolerates it may leave you beyond the intended route. Return to a valid room before disabling DNCLIP, and reload if a trigger was skipped.
Common questions
Why do codes fail on Damn I’m Good?
The hardest skill disables normal cheat entry. Use a lower skill when testing these codes.
How are warp digits arranged?
One digit selects the episode and two select its level. DNSCOTTY203 means episode 2, level 03.
