Left 4 Dead 2 has a lot of amazing community made skins, but I noticed an abundance of skins from one game in particular. That game is ArmA.
I wonder why no one has or (maybe) have thought about porting the MX 6.5mm from ArmA 3 to Left 4 Dead 2. Maybe replacing the Desert Rifle or M16. It would be cool to see a weapon like that in this game.
