The single player is completely uninspired. Apart from the inclusion of the OWL, I'm struggling to think of a single thing that makes this anything more than a derivative shooter. Silly scripted on rail sections, cheap over used tactics like throwing a shed led of enemies at you, last encounter was lame, poor voice acting, missed potential with the confusing narrative, it was just mediocre.
MP is perfect? You get 7-8 shoddy maps with 3 classes that aren't even that great. They've stripped it down massively from the Killzone 2 and 3.
No auto aim is not a problem when you play on a map like Park for instance, and all that involves is spawn camping. Just work your way to the enemy spawn area, park a turrent in one lane and shoot at the doorway leading out of the spawn.
I said the graphics are great so why you're comparing it to something as lackluster as cod is beyond me.
The game was blatantly rushed to release. Looking at the list of things the devs are supposed to add later from community feedback shows that.
