Ooooops.
But yeah, console FPSs tend to have varying degrees of autoaim depending on the game. Vegas 1/2 have none, while the Halo aimer will 'follow' badguys strafing your vision if you get it over them. The CoD5 one will move over badguys within a cirtain area of your screen when bringing up the Iron Sights.
This might seem lame, but having played a lot of Red Orchestra (the best WW2 PvP shooter out there, period) pinpoint aiming became more of a sideline frustration to the cover and flanking than 'the game' and i'd really rather that losing in said game was a function of poor tactics and teamwork than poor aim on an individual level. It's not that i'm a bad aim either, it's simply that minute pixel clicking being make or break isn't my idea of fun. As such, in these games, i'll tend to use more close-combat based classes/weapons at which point the autoaim becomes fairly irrelivent either way.
