Awsome Online!!! bad sinlge player....
But where socom is good in online, its is bad in single player. Single player missions are extremely straight forward and boring. Such as disable reactor, plant bombs, rescue hostages, and it's liek this throughout the game. And the fact that single player is really short. You can also replay the missions that you have completed, but with a different set of objecives, but its just a mere distraction, and pretty boring. A.I. is really dumb, just sits there shooting at you, provides for to easy targets. Yo also travel through the game with a partner, i would say he is pretty smart, actually overs your rear,so you dont have to do everything.
Overall the game balances out, and is really good, just dont buy it if you don't have online, Unless you really want a Socom game, and your a big fan.
