Start the game with a -dev command line parameter. To do this, create a shortcut for the game, right click the shortcut and look for a field called "Target." After the application path, enter " -dev" in the quotes. Select OK and start the game from that shortcut to use the following cheats. When in gameplay, press [Ctrl] + [Shift] + ~ to bring up the console. Enter the cheats there.
