Owners of Assassin’s Creed Unity for the Xbox One can expect the Dead Kings add-on content to be available to download over Xbox Live tomorrow.

Assassin’s Creed Unity developer Ubisoft announced the availability of the Dead Kings DLC last week, finally bringing the content that it’s been teasing in the game since launch this past November. Dead Kings for Assassin’s Creed Unity will take Arno Dorian to Saint Denis, the ancestral burial ground of future kings. In the add-on’s campaign, players will hunt down grave robbers and more. New armor and co-op missions are included in Dead Kings, along with a new hybrid gun that doubles as a long-range weapon: the Guillotine Gun.

Everyone who purchases Assassin’s Creed Unity will get Dead Kings free of charge. The free add-on content is part of Ubisoft’s apology for bugs that plagued the game during launch.
