COPERNICUS CONSPIRACY
Copernicus Conspiracy is a free downloadable content pack for Assassin's Creed: Brotherhood, released exclusively for the PlayStation 3 on the game's release. It focuses on the
famed astronomer Nicolaus Copernicus, who gets into trouble with the Vatican, who do not want Copernicus educating the public about astronomy. The pack consists of eight optional
missions, ranging from courier, assassination and protection objectives.
The plots starts with Nicolaus Copernicus sharing his teachings to a crowd within the Palazzo Senatorio, in clear defiance against the Templars' wishes. As Ezio arrives, Vatican guards
arrive to kill Copernicus to prevent his teachings from spreading. Ezio saves Copernicus and escorts him to a small safehouse outside the Colosseo. Copernicus, wanting to warn the other
scholars in Rome, gives Ezio letters to hand to them before they are assassinated by the guards. Whilst it is too late for one of the scholars, the others manage to escape. Upon arriving
back, Copernicus comes to the conclusion that it is the "Master", a man appointed by the Pope to keep Rome's philosophy pure, who ordered the killings. Ezio tails a cardinal to a meeting
with the Master and overhears a discussion of five of Rome's best guards going out to deal with the situation. Ezio kills them and reports back to Copernicus, who informs him that there is
a Lunar Eclipse he wishes to chronicle.
Ezio returns to Rome and kills the Master with his Hidden Blade. In his dying words, the Master reveals that guards are already on their way to kill Copernicus and that Ezio is too late.
Under the eclipse, Ezio rushes back to kill the guards before they get to Copernicus. After this, Copernicus indulges Ezio with some of his findings. Copernicus thanks Ezio, and the two go
their separate ways.
THE DA VINCI DISAPPEARANCE

Belriguardo Castle, where he encounters Lucrezia Borgia and the Pythagorian Temple.
The pack contains eight new singleplayer missions and two new locations, as well as two new gameplay features, including gambling in the Thieves Guild, and ten achievements. The
