HedonismBot 0 Posted June 17, 2012 Just bought Arma 2: OA on steam. It shows up as a seperate game from Arma 2. Do I only need to download and install OA or do I have to do both? Share this post Link to post Share on other sites
chrispow 3 Posted June 17, 2012 Do you own Arma II on steam as well, or as a physical copy?You will need both games installed. Share this post Link to post Share on other sites

HedonismBot 0 Posted June 17, 2012 I own them both on Steam. Thanks for the quick reply. Looks like I have a couple of long downloads ahead of me :( Share this post Link to post Share on other sites
