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.
Some footage recorded from a test mission using the Cold War module for WW4 Extended. US mechanized rifle company vs Soviet motorized rifle platoon in the Nogovan city of Petrovice. All effects are enabled and several objects (barricades, forts, groves) were placed to provide cover to the assaulting team.
