A custom campaign for ArmA2 Combined Operations. Official DLCs - BAF and PMC, are recommended for best experience, but not required.
8th mission of the campaign is now available as MP version for 1-9 players. Installation: Unpack the 7z file and put the pbo file to MPmissions folder in ArmA2 folder. Requires ACR DLC or free lite version of it. Let me know if you find any issues.
