(re: PQ2 Terrorist help needed!)
ummm… I’m trying to remember exactly when it happens, but at some point before this your gun gets knocked around. (I think it’s at the motel, doesn’t it get banged against the wall when you open the door?) You have to fix the sights again after this happens, and before you get on the plane.
Also when you do the sights on your gun, make sure you are bringing the poster forward and looking at it. The game will tell you (and you’ll get points, I think) when it’s sighted properly.
Otherwise, I’m not sure what to tell you…
