In Operation Flashpoint: Dragon Rising, the entire single player campaign is fully playable co-operatively for up to four players online. Teamwork and communication are key as gamers take on USMC infantry and spec ops roles battling the might of the Chinese PLA as the war plays out across Skira island.

The ‘Overwatch’ DLC extends the unique Operation Flashpoint: Dragon Rising experience in solo, co-operative and adversarial play. In new multiplayer mode Blindside the PLA must complete objectives in the shortest time possible while the USMC defends in tense, tactical engagements. An additional new mode, Supremacy, tasks opposing forces to occupy strategically vital positions featuring force multipliers like gun emplacements and air strikes.

These new multiplayer modes are complimented by two exhilarating new FTEs. In Friendly Skies, PLA anti-aircraft artillery prevents US airborne reinforcements inserting into the combat zone. Players must remove that threat and then defend the position from a PLA counter attack. In Hostile Takeover, intel reveals enemy movement in the village of Armudan, a perfect base for launching attacks deep into enemy territory. Gamers must flush out the PLA, establish a perimeter and hold their ground against a new enemy assault.

The ‘Overwatch’ pack will be available from Xbox Live Marketplace (400 Microsoft Points) today and will be available on the PlayStation Network (£3.19 / $4.99 / €3.99) and PC (free to download) soon.
