Players will experience the intensity, diversity and claustrophobia of a present day conflict from the unique perspectives of an infantry marine and a Special Forces officer, each engaged against the full force of the Chinese PLA on the huge open-world island of Skira. Gameplay simulates an immense conflict between advanced forces and provides unparalleled scope with different military disciplines, vehicles and equipment for players to utilise.
Currently the best place to buy looks to be play.com not only selling it for almost half price but if you pre-order it you also get an exclusive code to unlock an extra mission.
