This game would be OUTSTANDING if the aiming controls were more like Halo!
Multiplayer is amazing...the graphics (in multiplayer) are excellent, framerate butter smooth, and the action is fast (with the bots -- haven't played with a human yet).
The weapon choices, etc. are great -- it's just that crap auto-aim and the bouncing manual aim (and no melee that I've found -- yet)!
I cleared the first level on normal (completing all objectives/sub-objectives) and the only complaint so far has been a lack of checkpoints (only 1 -- midway through).
I'll get deeper into the game and give a more in-depth analysis -- but so far, it's like a supermodel in a chastity belt -- now if I could just find the key to that freakin' lock!
