Today, Ubisoft announced that Assassin’s Creed Unity – Dead Kings, the downloadable campaign that continues Arno’s story after the events of Assassin’s Creed Unity, will be available for free to all purchasers of Assassin’s Creed Unity for the Xbox One games and entertainment system from Microsoft and Windows PC on January 13, and on the PlayStation 4 computer entertainment system on January 14 2015.
After the events of Assassin’s Creed Unity, Arno leaves Paris for Saint Denis, a mysterious city that holds the crypts of deceased French kings. Sent on a mission to the extensive underground of the Basilica, Arno will face a faction of new foes, the Raiders, populating its catacombs. Equipped with a lantern and a new powerful weapon, the Guillotine gun, Arno will have to navigate the dangerous passageways to uncover the darkest secrets of the city.
In addition to a fully-fledged main single-player campaign, Assassin’s Creed Unity – Dead Kings also offers new open world activities and side missions, including new Murder Mysteries, enigmas and cooperative missions. Both single-player and cooperative modes enable players to unlock new weapons, gear and outfits that carry over between Assassin’s Creed Unity and Assassin’s Creed Unity – Dead Kings.
