In the game directory path Dark Reign\Dark=\Shell, you'll find a file called shellcgf.hte. Right-click on it and select Properties, then remove the tick from the read-only box. Open this text file in Notepad (or another text editor) and you'll find a section called menu mission buttons. Look for the line #define BTN_MISSION_COEFFICIENT 150. Change the 150 to 157, save and close. Run the game and you'll see a new cheat button at the bottom left-hand corner of the screen.
