You will have a hard time on Pro mate, that i can guarantee ya ^_^
But if I remember well, then if you did Separate Ways before you do Pro, then you should be able to use the mafia costume what gives Ashley armor and that's easier to play on Pro, although you will still see "you died" a few hundred times on your screen
Sidenote: Just take your anger on your little bro or sis, we don't want the PS2 or controller broke aight?
