Invincible - Medal of Honor: Frontline
The Invincibility code goes like this,
B,L,B,R,Y,L,X,control pad down
Q: Where do you do this at?
A: Pause the game and use that code and after you press D-pad down the game will resume.
This works w/o a cheat divice like a Gameshark or an Action Replay.
Have fun killing your enemies without a takin' hit on the damage meter.
