Ubisoft Montreal is developing Assassin’s Creed II on all current-generation platforms for a scheduled Christmas 2009 release.

Assassin’s Creed II is the product of over two years of intensive development by the original creative team behind the Assassin’s Creed brand. In a vast open world environment, the game invites players to incarnate Ezio, a privileged young noble in Renaissance Italy who’s been betrayed by the rival ruling families of Italy. Ezio’s subsequent quest for vengeance plunges players into a story that offers more variety in missions, new gameplay elements, diverse weapons and a profound character progression.

“Our creative team is working hard to top the experience of Assassin’s Creed,” said Patrice Desilets, creative director at Ubisoft. “We’ve made improvements to every aspect of the game. We’ve plunged ourselves into the stunning history of the Italian Renaissance so that we can offer fans a unique, varied and innovative Assassin’s Creed experience.”

Further details and screenshots are expected to be released shortly.
