Assassin's Creed II is a 2009 action-adventure video game developed by Ubisoft Montréal and published by Ubisoft.[1] It is the second major installment in the Assassin's Creed series, and the sequel to 2007's Assassin's Creed. The game was first released on the PlayStation 3 and Xbox 360 in November 2009, and was later made available on Microsoft Windows in March 2010 and OS X in October 2010. Several minor game-related features could be redeemed on Uplay and three downloadable expansion packs, including two story expansions, were released on Xbox Live and later to other platforms. A three-part live-action short film, titled Assassin's Creed: Lineage, which serves as a prequel to the main story and stars most of the game's cast, was produced and released on YouTube to promote it ahead of release. The game's plot is set in a fictional history of real-world events and follows the millennia-old struggle between the Assassins, who fight to preserve peace and free will, and the Templars, who desire peace through control. The framing story is set in the 21st century and follows Desmond Miles as he relives the genetic memories of his ancestor, Ezio Auditore da Firenze, to uncover the mysteries left behind by an ancient race known as the First Civilization in the hope of ending the Assassin-Templar conflict. The main narrative takes place at the height of the Renaissance in Italy from 1476 to 1499, and follows Ezio's journey as an Assassin while seeking revenge against those responsible for the death of his father and brothers. Gameplay focuses on using Ezio's combat, stealth, and parkour abilities to defeat enemies and explore the environment. The game features a large open world comprising several Italian cities, including Florence, Venice, Monteriggioni, San Gimignano, and Forlì, all of which have been accurately recreated to fit the game's historical setting.
