Quazzymojo 0 Posted September 1, 2012 Had ARMA 2 for a while and wanted to get op Arrowhead to play day z. Can I run it using the disc ARMA 2 and operation arrowhead on steam? If so it it easy to do? Cheers Share this post Link to post Share on other sites
Mentize 21 Posted September 1, 2012 I guess its possible, just make sure run both Arma II and Arma II: OA before installing DayZ to the Arrowhead directory.Doesn't hurt to try? although if this is deciding whether you buy Arrowhead or not, I'd wait for somebody who's done this and succeeded/failed to reply.

raisfas 0 Posted September 1, 2012 I'm in a similar situation. I own Arma II on steam and I was wondering if by purchasing OA will be enough to play this mod or if I'd need to buy the CO as a package. If anyone could tell me i'd appreciate it Share this post Link to post Share on other sites

AmberHelios 2071 Posted September 3, 2012 yes you can as Arma is not a "steamworks" drm and can be run without steam running just like a retail version the wiki tells you how to install it http://www.dayzwiki.com/wiki/How_to_install_DayZ#ARMA2_Mixed_copy_.28Retail_.2B_Steam.29i recommend using dayzcommander and showing it the install paths to both arma2 and arma2oa just make sure you run steam in admin mode to put the cd key into the registry if you need any help pm me hope this helps Share this post Link to post Share on other sites
