Following on from what appeared to be some premature bean-spilling, Ubisoft has now released the debut trailer for Assassin's Creed III, the latest addition to their successful stealth-combat action series and the first game in quite a while to feature a new protagonist.

Set against the backdrop of the American Revolution in the late 18th century, Assassin’s Creed III introduces a new hero, Ratohnhaké:ton, of Native American and English heritage. Adopting the name Connor, he becomes the new voice for justice in the ancient war between the Assassins and Templars. Players become an Assassin in the war for liberty against ruthless tyranny in the most stylised 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.

Assassin’s Creed III is powered by Ubisoft-AnvilNext, a revolutionary new game engine that delivers breakthroughs in visual quality, character models and artificial intelligence. Assassin’s Creed III will feature a ground-breaking level of stunning graphics that bring Colonial America to life.

Assassin's Creed is due on October 31st 2012 for Xbox 360, PlayStation 3, PC with a Wii-U version also in the works (presumably in time for launch), although the press release neither confirms nor denies a simultaneous launch for the PC version this time around.
