Assassin's Creed Rogue is a 2014 historical fiction action-adventure open world stealth video game developed by Ubisoft Sofia and published by Ubisoft. It is the eighth major installment in the Assassin's Creed series, and acts as a sequel to 2013's Assassin's Creed IV: Black Flag and a prequel to 2012's Assassin's Creed III with its final mission being the prologue to 2014's Assassin's Creed Unity. The game was first released on the Playstation 3 and Xbox 360 in November and December 2014, and will later be made available on Microsoft Windows in 2015.
The story is set in the mid-18th century during the French and Indian War, and follows Shay Patrick Cormac, an Assassin-turned-Templar. Gameplay in Rogue is very similar to that of Black Flag with a mixture of ship-based naval exploration and third-person land-based exploration with some new features.
