I read in the new update of AC revelations:
Assassin's Creed Revelations "Maps Pack - Trial Version": Play for free 6 multiplayer maps, including 3 new locations (Jerusalem, Imperial and Dyers) and 3 maps from Assassin's Creed Brotherhood (Siena, Firenze and San Donato), for 2 days.
Download the Assassin's Creed Revelations Upgrade Key to upgrade your Trial version and enjoy its content without any limitation. This will also unlock the customisation items for your characters.
So where do get this UPGRADE KEY ??? EzioLover 02:42, February 4, 2012 (UTC)
