I DLed the demo yesterday, and I feel underwhelmed. I thought this was supposed to be as good as COD4, but obviously not. My gripes are with the controls - I haven't managed to customise them yet, haven't worked it out, although I know you can - the turning speed, it's far too slow, even on maximum sensitivity, and actually killing the Helghast, because they take too many bullets before dying. If I was a member of Blockbuster or someplace similar, I would definitely rent it, but I won't be buying this judging by the demo.
