And the van mission that was talked about a few quotes higher than this one i found it fairly easier with the fast motion or slow motion cheat witch are:
Faster Gameplay:
R1, R1, L1, R1, R1, L1, Down, X
Slower Gameplay:
R1, Triangle, X, R1, Square, Circle, Left, Right
It seems to make it harder for that o donnavins goons to navigate around!
