Something I was wondering while playing Crysis 2's campaign- the AI are completely oblivious to the fact that there's a big red laser shining in their eye or poking out from cover. Will they be more alert to the existence of a laser sight in Crysis 3?
Honestly, I believe doing this would make laser sights so bad nobody would use them.
Laser sight is already a significant disadvantage in MP (not only you are missing one attachment, you also become a lightshow). Let's not gimp it further in SP!
