nomad_man 10 Posted December 20, 2011 I suggest getting combined ops (a2 + oa) which allows to mix the both worlds. Share this post Link to post Share on other sites
Angus S 10 Posted December 20, 2011 If you can only get one, OA probably has a bigger online player base, but I would recommend getting reinforcements as you get the online content for OA plus oth DLC's Share this post Link to post Share on other sites
sik 10 Posted December 20, 2011 Get OA. You can download Arma2Free and make Arma CO. Perfect for MP. Share this post Link to post Share on other sites
gossamersolid 155 Posted December 22, 2011 Why get one or the other when you can have both in a package called Combined Operations :p Share this post Link to post Share on other sites
