Today, our friends at Ubisoft 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 heliocentric philosophy, 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.
