Assassin's Creed Rogue is the sequel to Assassin's Creed IV: Black Flag and the prequel to Assassin's Creed III and saw release in late 2014 on PS3 and Xbox 360 (the last AC title to be released on old gen consoles). The game later saw release on PC, but now Ubisoft has announced that the Ubisoft Sofia developed game is hitting PS4 and Xbox One on March 20.
Here's a brief description of the game courtesy of the press release:
"Assassin's Creed Rogue tells the unique story of Shay Patrick Cormac, a fearless young member of the Assassin's Creed Brotherhood, who undergoes a dark transformation from an Assassin to a grim and committed Templar who hunts down his former brothers. Players' journeys will take them from beautiful New York City to the Wild River Valley and icy cold waters of the North Atlantic."
Ubisoft also announced that the Assassin's Creed franchise has sold in excess of 105 million copies in total, making it one of the best selling video game franchises of all time.
