All Cheats:
Everything remains the same as MOHAA except that +set cheats 1 comes before set ui_console 1

To enable cheat mode, start the game with the following parameters (Right click a shorcut and edit the properties):

+set cheats 1 +set ui_console 1 +set thereisnomonkey 1

Example:
C:\MOHAA\moh_spearhead.exe +set cheats 1 +set ui_console 1 +set thereisnomonkey 1

If your target contains quotations, you must put the parameter OUTSIDE of the quotations.

"C:\MOHAA\moh_spearhead.exe" +set cheats 1 +set ui_console 1 +set thereisnomonkey
