Assassin's Creed: Brotherhood is a 2010 historical action-adventure open world stealth video game developed by Ubisoft Montreal and published by Ubisoft. It is the third major installment in the Assassin's Creed series, a direct sequel to 2009's Assassin's Creed II, and the second chapter in the 'Ezio trilogy'. The game was first released on the PlayStation 3 and Xbox 360 in November and December 2010, and was later made available on Microsoft Windows in March and June 2011.
The story is set in a fictional history of real world events set in two time periods, the 16th and 21st centuries. The main portion of Assassin's Creed: Brotherhood takes place immediately after the plot of Assassin's Creed II, featuring 16th-century Assassin Ezio Auditore da Firenze in Italy and his quest to restore the Assassin order, and destroy his enemies: the Borgia family. Intersecting with these historical events are the modern day activities of series protagonist Desmond Miles, who relives his ancestor Ezio's memories to find a way to fight against the Assassins' enemies, the Templars, and to prevent the 2012 apocalypse.
Assassin's Creed: Brotherhood is set in an open world and presented from the third-person perspective with a primary focus on using Desmond and Ezio's combat and stealth abilities to eliminate targets and explore the environment. Ezio is able to freely explore 16th-century Rome to complete side missions away from the primary storyline. The game introduced a multiplayer component to the series, portrayed as a Templar training program.
The game received critical acclaim along with multiple awards including a BAFTA award for Best Action Game. It was followed in November 2011 by Assassin's Creed: Revelations, a direct sequel that served as a conclusion to Ezio's story and continued the story of Desmond Miles.
