Sony Social Media Manager Jeff Rubenstein has unveiled details today on the free Assassin's Creed Brotherhood PS3-exclusive DLC coming from Ubisoft.
To quote: Today, our friends at http://www.ubi.com/ shared with us details of Copernicus Conspiracy, a free, PS3-exclusive download for Assassin's Creed Brotherhood.
This additional content revolves around Renaissance astronomer Nicolaus Copernicus (see what I did there?), who will have extra assignments for Ezio, including courier, assassination and protection missions.
The missions are part of a storyline involving a conspiracy against Copernicus and his http://en.wikipedia.org/wiki/Nicolaus_Copernicus#Heliocentrism, which was revolutionary at the time.
The Copernicus Conspiracy content will be available for free download on November 16, 2010, which happens to be the day Assassin's Creed Brotherhood launches for PlayStation 3.
