Operation Flashpoint Mod — WW2 Collection Pack
The WW2 collection pack combines the most popular WW2 addons and missions for Operation Flashpoint: Resistance into one package. It offers a wide variety of tanks, planes, infantry, and weapons, and is easy to install — rather than have to install each mod separately, the pack batch installs them for you.
The pack includes its own loading screen and three entire campaigns — though one is completely in Russian. If, for some reason, you never bothered to learn Russian, you’ll have a hard time understanding that one.
