I've already got it and it's dissapointed me so far.
Horse is basically the exact same, only with a few pointless extra defence add ons.
Beast is decent but almost impossible to get to a high level by yourself, will get boring fast.
Haven't played campaign so can't comment but i'm sure it will be the dogs bollocks.
Multiplayer is alright, very much the same with a few bits and bobs tinkered with.
7/10 for me. Great game but just like an updated version. Think COD5 from COD4
