Alien Carnage / Halloween Harry 

Customer Cheat
  • Pressing [B] [I] [G] all at the same time will give you full health and jetpack power.
Debug Mode The following debug keys work for version 1.1 of Halloween Harry only:
  • [Ctrl] [R] [E] [N] - Gives you all weapons, and activates god mode for several seconds.
  • [alt] [L] - Level warp. Type the number of the episode (1-4), followed by the number of the level (1-5). Illegal input will dump you to DOS. This can not be used in the shareware version to access levels in the registered version.
  • [alt] [=] - Change location within a level. Type coordinates after this code; illegal input will probably crash the game.
Tech Parameter
  • Pressing these four keys at the same time will show you the coordinates you are at on the level. This serves no real function on its own, but it is used by Apogee's Game Hint Line sometimes to locate a player in a level. The keys are [ctrl] [alt] [rshift] [F12]
Misc Command Line Parameter
  • "skip" will start the game directly from the main menu.

  • "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. In short, using cheat keys can cause the game to malfunction or crash. Use at your own risk!
