Real intense action and gameplay, but don't expect you can play it for months if you don't like multiplayer gaming.
Call of duty does not give a basic storyline, but loose events of WW2 of the Americans, Britain and Russians. When you play the levels, other computer controlled characters give you instructions what to do, which is cool. You kinda relate to certain characters during the games, mostly during the British campaigns. Yeah, that's it I suppose, not much of a storyline..
Really good graphics in general, thow the ground is a bit blocky, and when you walk through smoke or dust, it slows down the frame rate. sounds good to.
Really great game, doesn't last all that long thow, because of the few levels available. If you have played Call of duty 1, you will like this one cause of the even more intens gameplay and number of artillery men. Realise that this game doesn't gives you a big single player, more of a multiplayer experience. So if you don't like multiplayer gameplay, this game will be much fun for a week or 2, after that, it will start to get old (though playing a fast game of ss-killing stays fun forever ;) !).
