Developers Ubisoft has just released the official E3 2012 trailer and the walkthrough missions for “Assassin’s Creed 3.”

While the official trailer looks amazing and takes the game to a whole new level, the gaming fanboys should remember that it’s CG and does not characterize the actual game.

The game allows you to pursue your enemies through a massive and dynamic world. Legendary battlefields of Lexington and Concord and the crowded streets of Boston and New York are on the cards, apart from the snow-covered Appalachian wilderness.

To help you in your quest, the game will also direct you to form an alliance with General George Washington, the tenacious commander-in-chief of the Continental Army and the first President of the young United States.

The new game is powered by the charismatic new engine, Anvil Next, which has been designed exclusively for "Assassin’s Creed 3." It was reported that the team of developers spent three years building this revolutionary system from the ground up, and it now provides stunning breakthroughs in motion-capture, face-capture, voice over (a first for videogames), animation and AI technology, which deliver more realistic character animations and interactions than ever before. It also provides real weather, seasons and time which go on to affect the world around you.

“Assassin's Creed 3” will be set during the American Revolution from 1753 to 1783, featuring a new protagonist, Connor Kenway, and is set to arrive in October this year for PlayStation 3, Xbox 360, Wii U and PC.
