BAF is comming soon. Somehow i get the feeling that this expansion was on shelf when Arrowhead was released.
Seems modern these days. Release half finished games. Of downloadable content as the call it.
Again a Arma community splitter, those who have it, create mods and maps with it. Breaks compatibility with regular arma. I recall operation flashpoint: cold war crisis a few years back.
My two cents to DLC.
