BryceButler-97 0 Posted December 19, 2013 (edited) Hello, my question is I wanted to play dayZ but, didn't want to buy it, so I downloaded arma 2 combined operations and downloaded it off a friends account, but now because we have the same CD-Key we can never play together if I want to play do I only have to buy Arma II OA and replace the CD-Key? Because I have already got Arma ii and the DLC's installed but I heard dayZ only uses the OA CD-key. Edited December 20, 2013 by BryceButler-97 Share this post Link to post Share on other sites
Sula 1205 Posted December 20, 2013 (edited) Hi, you each need to buy the software you intend using. You both need Arama2 combined ops (not sure what steam calls it now). You can't both use the same key. That would be theft, in my view. Edited December 20, 2013 by Sula Share this post Link to post Share on other sites
