Picked it up about two weeks ago and played through the Campaign a bit. A friend of mine still owned the game, so he decided we should mess around on Multiplayer. Unfortunately, most of the games or free roam have casual aim on so auto-aim really ruins any kind of personal skill involved. Then, to make things worse there's still a few people on there who've been playing since the game originally came out and know the exact amount of pressure it takes to instantly get a head shot after using the auto-aim feature. It's a bit of an annoyance when you just want to have some fun and some dude is the end all, be all expert of headshotting.
