Assassin's Creed Revelations DLC pack The Lost Archive will feature new single-player story missions detailing the life of Subject 16.
A trailer seen on Zavvi.com promises the DLC will reveal Subject 16's real identity and his relationship with other assassins featured in the hit series. Fans can also look forward to cameos from characters past and present.
Gameplay will take the form of the puzzle-platforming sections previously seen in the Desmond sections of Revelations, set within the Animus.
According to details on Zavvi the DLC will also offer three character skins, Ezio Turkish Assassin Armour, an Altair robe and The Armour of Brutus.
The Lost Archive will launch on February 28, or newcomers to the game can wait for the Assassin's Creed: Revelations Ottoman Edition released March 30.
