Buying operation arrowhead

[Maxforce]

Hi guys, i have had arma2 (non-steam version) for some time now and im looking at getting Operation Arrowhead.
i know you can get combined operations but beens as i already have the original arma2 what should i do so i get both of the content in one game, for muliplayer.

Sorry i know this has probably been answered before but i dont have time to do a search. (dont you just love work!)

just get OA, then install OA in same folder as your Arma2, then you can call yourself a proud owner of A2 CO.
I personally DO NOT recomend steam for Arma2, so get it from sprocket or a hardcopy.

Combined Operations is just the name for Arma 2 and Operation together, that name seems to have confused a few people :D
As Demonized says it's just a case of installing both on the same computer, in the same folder (by default both install in the same folder, Programfiles/Bohemia Interactive Studio/Arma2)
