Cheat Mode:
Note - cheats will not work in v1.1 or higher.

To access the cheats you must first edit the desktop shortcut. To do this, right-click on the desktop icon and go to Properties. Now in the Target Field, edit the command line so it reads:

"C:\program files\eagames\moh_spearhead.exe" +set developer 1 +set ui_console 1 +set cheats 1 +set thereisnomonkey 1 +set cl_playintro 0

Now click "Apply" and then "Ok." When in the game, press ~ to display the console window, and then enter the following cheats:
