Ubisoft has just formally lifted the lid on Assassin's Creed: Revelations, after a week of Facebook teasing.
Due on PC, PlayStation 3 and Xbox 360 in November, it's billed as the final chapter in the Ezio trilogy.
The new titles sees the AC2/Brotherhood hero following in the footsteps of his mentor, Alta´r, and heading to Constantinople in the heart of the Ottoman Empire.
A growing army of Templars is apparently threatening to destabilise the region, so clearly some covert sneaking and stabbing is in order.
New gameplay tweaks are also promised, including the ability to manipulate Desmond's memories to help "decipher the mysteries of his past and gain insight into the future."
Alongside the main single player campaign, you can expect a "refined and expanded" multiplayer experience featuring new modes, maps and characters.
"Delivering the final chapter of the Ezio trilogy is an important milestone in the Assassin's Creed franchise for us and for our fans," commented creative director Alexandre Amancio.
"Assassin's Creed Revelations includes lots of new features and some significant surprises. We can't wait to show our fans what we have in store at E3 this year."
