Assassin's Creed: Embers is an animated short film project made to expand the Assassin's Creed series. It was revealed by Ubisoft on 6 June 2011, and is set for release on 15 November 2011 with the release of Assassin's Creed: Revelations Animus, Collector, and Signature Editions.
UbiWorkShop released a teaser trailer on 21 July 2011, which was featured at Comic-Con 2011.
At the Comic-Con 2011 Assassin's Creed: Revelations Panel on 23 July 2011, the panel explained that the Embers trailer shows an older Ezio with his family. He fears someone is trying to get him. Embers is a narrative in the game you cannot play. The panel recommended watching Embers after completing Revelations, so that they are experienced in order.
