Take a good look at the image above, because it’s going to look really familiar once you see the sequel. The Assassin’s Creed Collector’s Edition packaging came with an Altair action figure, and the Collector’s Edition for Assassin’s Creed II ups the ante in all areas.
Not only does the “Master Assassin’s Edtion” include a very detailed Ezio action figure, it includes an art book (as standard nowadays) detailing the visual production of the game. And (as standard nowadays), those who pre-order at Gamestop will gain access to two exclusive in-game maps, Palazzo Medici and Santa Maria Dei Frari.
Update: Fixed terminology.
