Again, I never said I disliked Halo. The general impression I got from playing all the games in 2010 was that they were never able to fully repeat the quality of Combat Evolved, which I would probably put in my top five FPS campaigns ever (minus Library).
I think that game is nice, but I just don't car much for the lore which seems to be the center of all the marketing and coverage I've seen for Halo 4. I dunno I still can't find that much campaign footage from the game.
The E3 2012 trailer for H4 does a decent job of campaign footage stuff.
So far, all the media has let us know is that Cortana wakes Chief's slap happy ass up because their ship is going to shit and there is some bad mother fuckers who want to jack their shit up. Covenant apparently also are back and pissed off too.
Finally, Cortana is going cray cray because she's past the date A.I's are meant to be operational. Chief wants to get back to Earth to help her sweet blueberry nips out.
