These three Operation Flashpoint: Dragon Rising screenshots and the accompanying trailer show off the second DLC pack for Codemasters' shooter that's titled 'Overwatch'.

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.

Overwatch should be available today on Xbox 360 for 400 MS Points and shortly on PS3 for £3.19 and to download for free on PC.
