Unlimited Lives and Super Machinegun
On the main menu, select Arcade Game, and then enter the following code:
(Using the D-Pad) Up, up, down, down, left, right, left, right, B, A.
If done correctly, the game will start up instead of backing out to the main menu. You will begin with 5 lives that never decrease when killed, and you will have a Super Machinegun weapon equipped at all times!
NOTE-Using this code disables all Achievements and you cannot upload scores to Xbox Live Leaderboards. The code will remain active until you exit the game using the Exit Game option in the pause menu.
