Actually, I agree Leemz... if your not really into this game with others coming out, it might be worth passing on... or maybe rent it or borrow it one day for the campaign.
That said... I love the new Horde 2.0 mode, very well done and tuned greatly, also that beats mode is quite good and different, humans are trapped in an area and you pick your "beasts" and try and kill the humans... IE: kinda like playing the zombies in left for dead, each beasts has a cool power.
I tried MP for about 15 mins, got my ass handed to me, never got one kill, lol.
I won't start the campaign for a day or two, when I have more time... SO NO SPOILERS!

BTW; how #%&*$# up is it to pay 60 bucks for this game; to find that the VIP pass is NOT included, for that you have to pay 30 bucks more... just to play on more maps and more modes... M$ really screwed us gamers on this one. IMO
