olicarnage 10 Posted December 29, 2011 (edited) Hi, A friend bought Arma 2 in a shop and Operation Arrowhead on steam. Can he combine the games to have Combined Operation without problem ? If yes, what is the procedure ? Sorry if a thread talk about this already but I've found nothing. Edited December 29, 2011 by Olicarnage Share this post Link to post Share on other sites
Dwarden 1124 Posted December 29, 2011 yes, install A2 and patch it to 1.11, run once to verify it works then install OA 1.60 from STEAM run OA and it should automatically detect the A2 and thus You have A2: OA simple as that ;) Share this post Link to post Share on other sites
