macgragor 0 Posted June 29, 2010 How compatible are these 2 games? Are addons interchangeable? Can one be upgraded to the other? Share this post Link to post Share on other sites
DaveP 66 Posted June 29, 2010 Of what I can tell unit, vehicle, AI addons seem to work conversions that deal with big changes to stuff like UI and the like don't (like ACE) And I imagine sound mods would work, but only with ArmA 2 units/same classnames as ArmA 2 units Share this post Link to post Share on other sites
manzilla 1 Posted June 29, 2010 I'm pretty sure this has been discussed many times in the proper threads and section. These 2 games are completely compatible. OA is the expansion(also stand alone though) so it's meant to be used with A2. Unfortunately some community content may not be. But just the 2 games vanilla, yes they work together.

nmdanny 22 Posted June 29, 2010 ArmA 2 and OA work fine i think most basic addons that add things like factions weps vehicles should work For me ACE2 is bugged (mostly the UI) Share this post Link to post Share on other sites
