Note: This procedure involves editing a game file. Always create a backup copy of the file before proceeding.
Use a text editor to edit the "mydefuser.ini" file in the "\advent rising\system" directory. Scroll down to the area with unallocated letters. Try using "y" and "u" for this, as you will not accidentally hit them during combat, and they are together where you can reach them easily. For "y", enter "Blizzow 1" so the line appears as "y=Blizzow 1". Press Y during game play to have all of the powers and weapons at level 5, including jump and melee. For "u", enter "god", so the line appears as "u=god". Press U during game play for god mode. The message "God mode on" will confirm correct code entry, however your health will still decrease, but you will not die when it runs out.
