just got it, unfortunantly i don't think it comes for pc on cd form, you have the get the dvd version (at leastwhere i bought it) but i reallly like the aiming, it's not accurate, it's not easy, and it defaults to not having a crosshair... the only thing that breaks this realism are some of the squad based actions you can take as well as the little "suppression" meter on the enemies that give away their possition. but overall, great game, worth getting.
