I posted this on another KZ2 thread but it seems relevant too here. This is the early critical consensus so far, so you can use this to judge whether or not the game is average or if you'll like it.
Well the early critical consensus goes as...
Mind blowing graphics
Tactical singleplayer, that plays great
But despite the first person cover system, it feels like we've been here before
And there should be more colors
It has a forgettable story
With horrible voice acting
Class based multiplayer, that plays great
With great match types
Ranking up and classes are great fun and provide for countless play styles
But seriously, where's the co-op?
And damn, this game looks good!
Final Score: 9.5/10
I haven't played the game yet; this just seems to be what is the consenus coming out of the reviews, and I don't see that changing when the game actually comes out, unless multiplayer ends up being really buggy like Gears 2.
Again this is not my opinion, it is the opinion of the gaming press, as a unit.
