I would have to post spoilers to give you examples, there or 10's of these, DO IT EXACTLY LIKE WE WANT YOU TO PLAY THE GAME or else we will KILL YOU OFF. REALLY I swear, in certian areas if you run in direction they dont want you to you just DIE, not bomb no gun. Then there is a place where if you dont keep your head down you get shot, BUT THERE ARE NO SNIPERS OUT THERE, I LOOKED
You just DIE <-------------BULLSH*IT
True enough. I could definitely tell where the scripted elements were but what was nice about Call of Duty was that it was done well enough that unless I deliberately went around trying to shoot your squadmates it didn't break the believability too much for me.
