Two new factions, the British Armed Forces and Private Military Contractors, are featured in this standalone expansion in the ArmA military combat series. In addition to the two playable forces, the expansion introduces new weapons, vehicles, and two maps. Each side is featured in a distinct single-player campaign, or players can choose from a variety of single missions that offer cooperative support. As with previous installments in the series, you'll be able to engage in full-scale online battles supporting up to 50 real-life players and hundreds of computer-controlled units.
