Global Storm mod is a simple mod with a simple goal of improving vanilla gameplay with semi-realistic style.
Global Storm Special Forces Edition is basically a GSmod v0.4 but made for Special Forces exp. This is standalone mod you DON'T need GSmod v0.4.
You must have installed Special Forces exp. and updated to latest version!
GSmodSF has new firing sounds that will be included in GSmod v0.4.5
One more thing, the goal of this mod IS NOT reality, this is how I see and like BF2 gameplay.
