Meh, my manager's hidden both copies. (Or so he says. I wouldn't be shocked if he's taken one or both of them home to try himself.) So no early impressions from me, I'm afraid.
Oh well, guess I'll have to wait for the official release. My housemate will be buying it (he's a big Halo fanboy), so I'll be looking forward to the 4 player splitscreen Firefight. Gears 2 Horde splitscreen was incredibly fun, and this looks be to be taken it up another notch.
