Assassin's Creed: Brotherhood - The Da Vinci Disappearance

The Da Vinci Disappearance is a downloadable content addition for Assassin's Creed: Brotherhood, bundled alongside Animus Project Update 3.0. It was released on March 8, 2011 for Xbox 360 (800 Microsoft Points), and March 9, 2011 for PlayStation 3 (£7.99 or $9.99). Accompanying this, it was included for free in the PC version of the game, due to the delay of the platform's release date.

The Da Vinci Disappearance memories could only be started after completing "Double Agent", though to complete the whole sequence, "High-Stakes Negotiations" also needed to be completed, although it takes place after Sequence 8 and before Sequence 9.
