Three years after the conflict in Chernarus, portrayed in the original Arma 2, a new flashpoint explodes in the Green Sea Region. Coalition forces led by the US Army are deployed to Takistan to quickly restore peace and prevent further civilian casualties.

You will enlist into various roles within the US Army, from basic infantrymen, through special operatives, to pilots and tank crew in this new installment in the award winning line up of military simulators for PC from Bohemia Interactive.

Building on 10 years of experience and constant engine development, Arma 2: Operation Arrowhead boasts the most realistic combat environment in the world. It models real world ballistics & round deflection, thermal imaging, materials penetration, features a realtime day/night cycle and dynamic wind, weather and environmental effects.

This may be a dumb question, but I'm new to desura and digital distribution. I have a copy of arma 2 bought in a store. So if I buy OA on desura, is there anyway that I will be able to run the 2 together as Combined Operations?

@JarryHead You have to use RegEdit(You can find how to combine those two into Combined ops by searching at BIS Forum) You can't play as Combined because you bought it seperately.So here the link :) Forums.bistudio.com
