IDEA Games and Bohemia Interactive announced today the development of ArmA II Operation Arrowhead; the standalone expansion pack to the ArmA II PC military simulator.

Three years after the conflict in Chernarus, portrayed in the original ArmA II, a new flashpoint in the Green Sea region heats up and coalition forces led by the US Army are sent to Takistan to quickly restore peace and prevent further civilian casualties.

Set into the new environment of hilly central Asia, Operation Arrowhead will offer combat simulation experience in a modern day setting with freedom of movement, actions and tactics. Players will enlist into various roles within the US Army, from basic infantrymen, through special operatives, to pilots and tank crew in this new instalment from Bohemia Interactive.

"Bohemia Interactive is fully committed to supporting the existing ArmA II user base whilst also working on the expansion pack, this will not only allow us to introduce a new and original theatre of war to the simulation series, but also improve numerous areas of the core game, for both the original game and the expansion, where we can go even further with adding completely new features" said Marek Spanel, Bohemia’s CEO.
