This is only my second ever COD single player experience, with the first one being Call of Duty 1 way back then on PC. Thought I would struggle with the controller, but the more you play, the better you get at it. Must say I enjoyed it more than I thought I would, and though the story and action sequences may be a bit over the top, I loved every bit of it and I'm considering a second playthrough. Graphics wise I was happy, though I have seen better looking games. Played it with earphones plugged into the controller and the sound was quite decent, and I could easily pin point where enemy fire was coming from. The advanced abilities and vertical aspect added to the game was also a nice touch.
Haven't tried online multiplayer as yet due to wobbly ADSL, so can't comment on that. Would like to try the exo Zombie storyline, but sadly you have to get DLC for that.
