overall the best damn comp game out there, for combat. like gizmo said about d2, fun and worth the money, but sof2 takes you in deeper, with sweet dl's to enhance your playing expernince, real like damage, knifes, all types of guns, and game play real life situations, teams friends, go pick it up, dont know how much it costs, got it with my new comp. no more than $50. graphics great kick ass game

ofcourse its sweet..
it uses the Quake 3 Engine
