Pre-order Assassin’s Creed III for Xbox 360 or PlayStation 3 at Best Buy in the United States or Canada, and you will receive a two-act mission called “The Ghost of War.”

ACT 1: A mysterious shipment aboard the HMS Windermere could turn the tide of the Revolution in favour of the Templars. Retrieve the cargo and make sure the Windermere and her captain both find a watery grave.

ACT 2: The HMS Leviathan is leaving for England with an important Templar emissary. Make sure the emissary and whatever information he holds are lost to the deep.

Complete both acts, and your reward will be Obwandiyag’s Pontiac War Club and the Crafting Blueprint for an Upgraded naval convoy which allows increased trade with overseas merchants.
