Looks lik ethe PC version is different to the 360 version, snippet from gamespot pasted below:
One of the things I like about PC games is that they are often not dumbed down so much for the more casual gamer. Thats why I'm probably sticking to the PC for my next gen system.
don't mistake the PC version for being a port of the Xbox 360 game. The PC version has larger and different levels than those featured on the Xbox 360, as well as a different graphics engine and style of gameplay. It will have a vastly different multiplayer suite, as well. Advanced Warfighter for the PC will ship with two multiplayer modes. There's a cooperative gameplay mode that lets you play the entire single-player campaign with up to four players, as well as a new domination mode, which feels like a nice twist on the conquest mode found in Battlefield 2.
