The best graphics I've seen so far! I've got an HDTV and tom clancy's rainbow six graphics were rubbish compared to this, even Resistance fall of Man doesn't come close.
The gameplay is fast and fun, from being in an infrared airship gunner, to a sniper, to an SAS soldier, to a helicopter gunner, to an american soldier. It's fast passed, and never stops till the end.
The only down side for me, was that the game was very short. I past it in 6 hours, and I'm no pro. But it does make up for this by its arcade mode you unlock once you end the game, and the online play is fantastic!!!
Split screen is OK, but you would really need 4 controllers to have some fun as you can't play against any AI, only each against other, and the maps are quite big.
In short, I'd definately recommend, but don't expect to be killing Terrorists for weeks on end
