Start the game with the command-line parameter 760722. Press [Q]
 during the fight to win.

 or

 I used a hex editor and did a search in the main game.exe for the value
 of 760722 and the result was anch760722.

 Next I created a shortcut for the game as folows:

 C:\Games\Odium\odium.exe anch760722

 After starting the game, the [~] or [F11] brings up a cheat console marked
 with X. Whichever character is selected, type in

 heal

 hit [Enter] and that character will be completely healed. You can even do
 this during combat. Also during combat, hit [Q] to win, but you get no
 experience points for the fight.
