A custom campaign for ArmA2 Combined Operations. Official DLCs - BAF and PMC, are recommended for best experience, but not required.
2nd 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. Note: the ingame cutscenes are not perfect in this multiplayer version. There is some timing issues.
