Today, On IGN.com IDEA Games and Bohemia Interactive announced the official Standalone expansion pack to ArmA II - Operation Arrowhead.
Quote Bohemia Interactive:
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, visually attractive environment of hilly central Asia, Operation Arrowhead will offer realistic combat simulation experience in a modern day setting with unprecedented 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 installment in the award winning line up of military simulators for PC from Bohemia Interactive.
