Cheat codes give the player an advantage during the game, from invincibility to infinite ammo. Originally, cheat codes were programmed into a game so that the developers could test the game easily without having to play it properly (i.e. they could become invincible so that they could fully explore what they had created). Since then, cheat codes have become a fond favorite of many people and developers.

Sometimes game developers will insert cheat codes that actually hinder the player, or restrict them in some other way, such as providing all weapons but when the player next dies the game quits. Some cheat codes exist purely for amusement, and serve no real purpose in games. Such cheat codes may also be called Easter eggs.

Duke Nukem I Edit

During gameplay, press the following keys together:

     "Backspace" and "Page Down"  - Gives fully-powered weapon, full health and all keys

Start the game by typing asp after duke1 in DOS. Then at the main menu, press the following keys together:

     "Alt" and "F6"  - Play the demo level

And during gameplay, press the following keys together:

G+O+D  - All items
G+O+W  - Warp you to the next level

Duke Nukem II Edit

During gameplay, press the following keys together:

     N+U+K    - Gives random items/weapon
     E+A+T    - Restores health to maximum
     G+O+D    - Displays a message

Duke Nukem 3D Edit

During gameplay, type in the following codes:

     DNCORNHOLIO  - Toggles God mode on/off
     DNKROZ       - Toggles God mode on/off and toggles infinite Jetpack
     DNGOD        - (World Tour only) Replaces the DNKROZ cheat
     DNSTUFF      - Gives all weapons, all inventory items and all keys
     DNITEMS      - Gives full armor, all inventory items and all keys
     DNINVENTORY  - Gives all inventory items
     DNWEAPONS    - Gives all weapons
     DNKEYS       - Gives all keys
     DNHYPER      - Gives Steroids
     DNSCOTTY#**  - Warps to a level
                              (Replace # with the episode number and the two * with
                               the level number, e.g. DNSCOTTY203 takes you to Episode 2, level 3)
     DNMONSTERS   - Toggles monsters on/off
     DNCASHMAN    - When the Open button is pressed, money is thrown out (Duke is damn rich!)
     DNVIEW       - Same as pressing F7
     DNRATE       - Shows the Frames Per Second (FPS)
     DNDEBUG      - Shows some debugging information
     DNSKILL#     - Changes the skill level to whatever you input for # (enter 0 for no monsters)
     DNBETA       - Displays the message "Pirates Suck!"
     DNTODD       - Displays the message "Register Cosmo"
     DNALLEN      - Displays the message "Buy Major Stryker"
     DNCOORDS     - Displays your coordinates
     DNSHOWMAP    - Displays the entire map
     DNCLIP       - Toggles Clipping Mode
                              (If you walk into empty space, such as inside walls, you die.)
                              (In versions 1.4/1.5, walking into empty space will not kill you.)
     DNUNLOCK     - Unlocks all doors and opens those that are not locked

Note that cheats are disabled on the hardest difficulty setting, "Damn I'm Good." However, it is possible to use God mode in this skill level; this is done by enabling the cheat at a lower difficulty level, and then switching to "Damn I'm Good," either by starting a new game or with the "dnskill#" cheat.

The "dnclip" cheat can occasionally cause the game to crash, especially when the player walks through undefined areas. However, using the cheat during automap mode seems to prevent this from happening.

In addition, entering these cheats may also activate items you are using.
