Bohemia Interactive has announced that ArmA 2: Operation Arrowhead, a standalone expansion for ArmA 2, will be released worldwide from June 29, 2010. Operation Arrowhead promises to deliver more highly authentic military simulation gameplay, while shifting the action to an all-new environment.

Set in the fictional region of Takistan and taking place three years after ArmA 2's campaign, Arma 2: Operation Arrowhead features three new world maps with new terrain: sandy deserts, a dense city with surrounding countryside and a rocky mountainous region.

Also included in the standalone expansion pack is support for controlling unmanned aerial vehicles (UAVs) to observe, strike and rescue from afar, along with a fully-modelled FLIR thermal imaging simulation to give the player advantages while working at night.

A new and chilling geo-political themed campaign is also included.
