Heres the crack, in the thread theres a post that this crack should work on each starforce protected game which is on CD for the PC. I tried to use it for Kill.Switch (Which has been brought to the pc from a console), but that didnt work.. So I guess its only for games which arent brought to the pc from a console or are on DVD.
