This may sound strange but an enemy that wasn't there a second ago killing me. I run in a building, check my corners, nobody's there so I proceed to run through the building and wham, I get shot in the back. I watch the kill cam and it shows me literally run in the room, stare at the guy then move on towards the other exit.
I know this is real because I have killed a few guys that literally ran right through me with out seeing me.
When I get killed after being around a corner or building.. on his screen it shows me not even attempting to run.. happened a lot in mw3 aswell which is why I ended up selling it. Idk not as bad in this one. But blops2 and mw3 are the only ones I've ever been killed by people from the movie wanted...:(
