It's week five, the final week in our Unlock the Animus challenge as we build up to the release of Assassin's Creed Revelations and today the last puzzle unlocks, opening up the doorway to the Mastermind challenge and the epic conclusion of your journey.
Week five promises to be yet another thought provoking, beard-stroking marathon but rely on your powers of logic and your ability to conceptualise and you will prevail, for this is a puzzle in which you must unravel the seals in more ways than one. Strive mightily, for ultimate success is within your grasp.
How have you done so far with these challenges? If you've managed to solve them, then we tip our Assassin's hood to you for if you've cracked even half of these fiendish conundrums and puzzles, you're better men than we and truly worthy to walk in the footsteps of Altair and Ezio.
But it's not too late to get into the game if you've never tried before, as with all the puzzles now open it's a straight foot race to claim the ultimate prize.
You could win a fantastic prize in the form of an amazing trip to Istanbul where Revelations is set. This will include travel for yourself and a friend, flights, four nights of hotel accommodation and £500 spending money, plus a chance to tour the beautiful and historic Constantinople of the Roman, Byzantine and Ottoman periods.
As a special treat for Assassin's fans, we've also got a bunch of exclusive interviews and content including news, movies and previews and the final of our series of interviews where scriptwriter Darby McDevitt and Creative Director Alexandre Amancio talk about the epic conclusion to the medieval portion of Assassin's Creed.
It's all here on our Assassin's Creed Revelations game hub.
Happy hunting and good luck.
