Part of the launch of Assassin’s Creed Revelations, a new URL destination called “Unlock the Animus” {link no longer active} has been launched tasking fans to complete a number of tasks designed to assess their problem solving abilities. Every seven days, a new task will be allowed and fans will have one attempt per day to solve the puzzle. To begin, fans can either log in with Facebook credentials or create and account and sign up. To qualify for the final challenge on November 8, fans must complete every Strand (puzzle). Winners will be eligible for a trip for two to Istanbul including flights, four nights of a hotel accommodation and spending money. Fans will be able to tour the beautiful and historic Constantinople of the Roman, Byzantine, and Ottoman periods, visiting the grand palaces, mosques and bath houses for which the city is famous.
