hey theWizardOfQuoz, thanks heaps for this and the time it took you to find out,
I know some people have issues with cheating to get the ranks but that's not why im here I used this last night and yeah that freezing think is a bit of a problem but I find away around this. instead of standing in the same room with the bomb and your guys leave the room the way you enter and walk around to the left and stand in front of that PC terminal and the game runs very smoothly and you still get all the normal XP let me know what you think,

thanx again Saint Death
