Duke Nukem: Zero Hour

The cheats in Duke Nukem: Zero Hour are unique.  You can't enter "codes" to get them; you must earn them by successfully completing levels.  In fact, various factors within the levels will enable certain secrets.  Once you have earned a secret, you'll need to start a new game and you'll be able to access the cheats from the main menu in order to enable them.  In addition to cheats, a new Dukematch character will become available, allowing you to play Dukematch with the character.  The following table shows which cheats are available, and what you must do to earn them.

  • "Customer Cheat" means it's the cheat given out with the registered version of the software.
  • "Debug Mode" means it's an unsupported cheat mode.
  • "Tech Parameter" means it's a code that does something, but really isn't a cheat, it's more or less there to help Apogee Customer Support.
  • "Misc Command Line Parameter" is the same type of thing as Tech Parameter.

Cheat keys are not officially supported by Apogee. If you use the debug keys, Apogee cannot provide any support, since this alters game performance to a state where our standard support comments and issues might not apply.
