to the main menu; hold both triggers/both thumb buttons and
simultaneously press following sequence (as fast as possible, I
believe you have 0.5 sec): white-black-black-white-white-black.
This should activate the
cheat menu. I know this is insane.
You can select
following cheats from the cheat menu: "Refill" and "All Weapons". We
would also have added "God Mode", but this would enable the player to
create deadlock situations (and even crashes because of the dynamic
memory consumption), which was not acceptable for a console game.
