Bohemia Interactive has released ArmA II: Operation Arrowhead for PC.
Operation Arrowhead is a standalone expansion that puts you in the no-doubt realistically modelled footwear of the US Army in a fictional Asian country called Takistan.
While it can be played on its own, Operation Arrowhead can also be integrated in ArmA II if you already own that.
The official website has a list of retailers stocking it, including digital distribution venues. It costs Ł24.99 on Steam.
You'll be able to read our review of the expandalone later today, but in the meantime check Tim Stone's detailed Operation Arrowhead hands-on preview to get a sense of it - or watch the video below.
