A custom campaign for ArmA2 Combined Operations. Official DLCs - BAF and PMC, are recommended for best experience, but not required.
New version again with a new mission. As a new very noticeable feature. You will meet active hostile/civilian life from random houses. Silent villages may turn into deadly panic. Player groupmembers also sometimes now shout of spotted enemy contact in building. Also many other changes and tweaks included. :)
