The official trailer for the highly-anticipated stealth action game Assassin's Creed III has been released, and game developer Ubisoft announced it will launch the game in the U.S. on Oct. 30, 2012.

Cover art for the game was leaked last week, leading to speculation about the game's setting in America during the Revolutionary War. The trailer and a Ubisoft press release confirmed this.

The trailer opens up with a bald eagle gliding above a snow-covered wilderness identified as the Mohawk Valley, located between the Catskill and Adirondack mountains of upstate New York, circa 1777. On the ground, bloodied corpses in red uniforms lie in the snow amidst the tattered British Union Jack. Viewers are then presented with a flashback to what is presumably night before.

The game's protagonist, a hooded assassin in buckskin leather, is introduced as he brandishes a tomahawk before attacking a small group British soldiers in the woods. Images of the swift and brutal killings are interspersed with the eerily quiet aftermath of the attack.

The trailer continues as the assassin sprints through the woods, leaping from tree branches, until he arrives at the crest of a hill that opens up to a battlefield below, where British and Continentals armies have assembled to fight.

 The time now near at hand which must determine whether Americans ought to be free men, or slaves, an American general says to his troops. Our cruel and unrelenting enemy leaves only us the choice of brave resistance, or the most abject submission. We have, therefore, to resolve to conquer or die.

The trailer ends as the American soldiers charge into battle against the British under a hail of gunfire.

Many have wondered if the series' newest assassin would have any Native American heritage given his choice of weapons and attire displayed in the leaked cover art. Ubisoft confirmed this, identifying the main character as Ratohnhakéton, who apparently is of both Native American and English descent.

Of course for the sake of convenience, the character goes by the less exotic name Connor.

Adopting the name Connor, he becomes the new voice for justice in the ancient war between the Assassins and Templars, a Ubisoft press release stated.

Players become an assassin in the war for liberty against ruthless tyranny in the most stylized and fluid combat experiences in the franchise to date. Assassin's Creed III spans the Revolutionary War, taking gamers from the vibrant, untamed frontier to bustling colonial towns and the intense, chaotic battlefields where George Washington's Continental Army clashed with the imposing British Army.

The game will be released on Microsoft's Xbox 360, Sony's Playstation 3, Windows PC and is in currently development for Nintendo's Wii U, the statement said.
