Infite life, weapons and ammo
by Mac Daddy

During Mission briefing, hold R1, R2, L1, L2, Triangle, Square, and O.  
Then press left on the D-pad.  This will give you infinite life. If 
you do the same thing during the part where it tells you the weapons 
you get, it will give you all weapons at infinite ammo.
