"What are the differences between Arma 2 Free and Arma 2? Well, first of all – it is free, we’ll get that out of the way. Secondly, it’s not a pay for content model at all; players of Arma 2 Free will only have access to the multiplayer. Purchasers of Arma 2 get HD graphics, the ability to install user mods, access to the single player/co-op campaigns and provided you buy the combined ops pack, the expansions Operation Arrowhead, British Armed Forces and Private Military Company."
