Deus

Follow these steps to activate the Cheat Mode in Deus:
1. Go to the main option panel.
2. Position the mouse pointer onto the top left of the screen.
3. Press the Alt, Ctrl and C keys at the same time. The animation
  of the mouse pointer should stop at this point.
4. Use the numeric keypad to type in 3615, then hit Enter
  (also on the numeric keypad). While you are typing, you should
  see the numbers appearing on the top left of your screen.
  After you hit Enter, the animation of the mouse pointer should
  resume. You are now in Cheat Mode.
Now, once you are in Cheat Mode, go to the normal, 3D game view.
From here, you can press Ctrl-T to all the weapons and set all of
your parameters to their respective maximums. This also gives you
all of the objects of the scenario, although they will still
appear in their normal locations - you will be carrying exact copies.
Important Note: dont press Ctrl-T while in one of the 2D panels or
while you are swimming.
