You know when you put in the Invincibility cheat and you can't find a way to test if it worked? Well now you can! Simply pause the game, press L1 L2 R1 R2 Triangle Circle X Square. Then, un-pause the game and press Circle to use one of your PK's(Pain Killers). If your health goes down, it didn't work but if your health doesn't go down, it worked. The other way to check is to take a Bazooka and blast it right at your feet!(<- this one's the stupid one.)
