With over one million copies shipped of the award-winning Operation Flashpoint: Cold War Crisis, Codemasters today confirms details of a dedicated expansion for the PC best seller titled Operation Flashpoint: Resistance.

Due to launch at retail on June 21st and requiring the original game to play, Operation Flashpoint: Resistance is a full expansion.

Enhancing the Flashpoint universe, Operation Flashpoint: Resistance creates an additional 100km2 island complete with industrial-style buildings and original landscape scenery. Thanks to the use of high-resolution textures throughout, the visuals will be much more detailed and dramatic than ever before.

The expansion also delivers a new campaign that forms a prequel to the original game’s plot and is set years before Operation Flashpoint’s Cold War hit crisis point.

Operation Flashpoint: Resistance casts the player as Victor Troska, an experienced ex-Special Forces militia soldier. Having turned his back on his military past, Troska has settled into a respectable civilian life on the island of Nogova*, a short distance from the original game’s three islands. However, his situation changes when the Soviet force invades the island group and destroys Troska's idyllic dreams.

Reluctant at first to return to a conflict situation, he is forced to participate in, and then lead, the ramshackle Resistance effort, which grows up in response to the Soviet occupation of the island.

As Operation Flashpoint: Resistance begins before the US Army and its resources came to the islands, players have to scavenge equipment from whatever sources they can manage, which provides for different play experience to the heavily-resourced original game.

Throughout the closely linked missions, the overriding objectives include growing your resistance force by gaining new recruits and gathering equipment, preserving as many of your comrades as you can to build an army strong enough to repel the Soviets.

With new vehicles and weapons featuring, a series of original multiplayer missions on the new island, and completely overhauled network code Operation Flashpoint: Resistance is scheduled for release on June 21, with a RRP of £19.99.
