As we always recommend use modfolders to separate the custom content from the official game content to prevent problems. For different ways to set up your modfolders and use them please visit Armaholic's FAQ.

When you are using the Steam version you can find a Steam mod installation and activation FAQ here. (Armaholic)


This mod requires both ArmA2 AND Operation Arrowhead to be installed as Combined Operations to work as intended. It will not work on a standalone ARMA2 or Operation Arrowhead installation as it uses many content and features from both.
