Pretty good. It's like Hidden & Dangerous combined with Call Of Duty. Or something like that. The graphics are decent and i was suprised how intelligent the enemy AI is. I mean, theyre not rocket scientists, but much more intelligent than the average Call of Duty enemy.
What I really like about this game, is that its never boring and the sniper rifle is among the best ive seen in videogame history. You have to take distance and wind into consideration before shooting. And theres this nice bulletcam thingy when you get a headshot from a far, or when you shoot a moving target.
The multiplayer seems to be good too. Ive only tried the deathmatch, but it was fun.
