   The codes.

   At the title screen press LEFT ALT RIGHT ALT and the MENU BUTTON on
the mouse all together. If you watch the scrolling text to the end then
it will tell you that F1 will cycle through the mini-guns, F2 will
cycle through the rocket launchers and F3 will restore your energy.
This cheat also works on the demo version.
