sound will play and a written confirmation will be given. Unpause the game and enjoy.

"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
"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!
