WW4 Extended is an unofficial expansion for the WW4 modpack, the OFP & CWA mod that focus on performance. It covers modern, Cold War era and Arctic warfare, adding numerous infantry units and vehicles for all sides, and provides several visual and sound effects (tracers, bullet cracks), support options and many other features.
The models for Russian motorized rifle units have been updated. Their gear and textures are closer to that of the 6B23. The digital flora pattern has been shrinked, so it's closer to the real life counterpart.
