Act of War is set in what is only referred to as “a near future” (possibly around 2010) where a crippling energy economy has forced gas prices in the U.S. to over $7 a gallon. The game begins when an oil facility in Houston is destroyed by a terrorist bombing one week before the “World Energy Forum” in London. Concerned with the possibility of an attack at the Energy Forum as well, the national security advisor is granted permission to activate “Task Force Talon”, an elite platoon of soldiers that is unknown to the public, to guard the World Energy Forum. The plot thickens when a major terrorist operation occurs in San Francisco, which results in the US government ordering a full troop recall in order to fight off any further attacks. In the singleplayer, there is only one campaign to play through which effectively puts you in the role of Army Major Jason Richter, where you command the forces of the US Military and Task Force Talon around the world and eventually in Washington D.C.
