Sony has revealed details of the PlayStation 3 exclusive content coming to Assassin's Creed III.

The content is a four-mission arc based on Benedict Arnold's secret plot to betray West Point and sabotage the American Revolution.

The missions begin with a special request from General Washington in exposing a rumoured plot to overthrow West Point, a critical link in the defence of the Colonies against Great Britain. Across four missions, Connor will flush out Loyalist spies and work undercover for Benedict Arnold, culminating in a full-blown assault on West Point.
