Ubisoft has announced that it will launch the Dead Kings campaign for Assassin's Creed Unity on January 13 after originally removing the DLC from the failed season pass in November.

Assassin's Creed Unity launched on November 11 to an unexpected storm of bugs and graphical issues that caused many long-time Assassin's Creed fans to express their displeasure with the game on forums and messageboards across the internet. This eventually led to an apology to be issued by the publisher and developer and a suspension of all season passes. Those who already purchased the $29.99 season pass were given a choice of several free games from Ubisoft's library, including The Crew, Far Cry 4, Watch Dogs, Assassin's Creed 4: Black Flag, Rayman Legends, or Just Dance 2015, and the Dead Kings DLC was announced to be given away for free as well.

"The launch of Assassin's Creed Unity was a highly-anticipated moment for me and for our development teams around the world who dedicated a tremendous amount of energy, passion and skill to the game's creation," wrote Yannis Mallat, CEO for Ubisoft Montreal and Toronto after the game's messy launch. "Unfortunately, at launch, the overall quality of the game was diminished by bugs and unexpected technical issues. I want to sincerely apologize on behalf of Ubisoft and the entire Assassin's Creed team. These problems took away from your enjoyment of the game, and kept many of you from experiencing the game at its fullest potential."

Assassin's Creed Unity is the seventh major installment in the series and it continues on with the familiar third-person open world exploration that fans have come to know and love from previous Assassin's Creed games. But in addition to that environment, Unity introduced a new parkour and stealth system, as well as a complete revamp of the combat system and cooperative multiplayer for the first time.

In the game, you play as Arno Dorian on a quest of revenge for your adoptive father's murder. The setting is late 18th century France during the French Revolution. But certain "time anomolies" allow the setting to change throughout important parts of France's history, including the occupation of Paris by Nazi Germany during World War II.

The Assassin's Creed Unity Season Pass includes with it a whole other separate game called Assassin's Creed Chronicles: China.

This stand-alone title is set in 16th century China and plays like a 2D side-scrolling game. Sure, it doesn't feature the amazingly gorgeous 3D environments that we've come to expect from Assassin's Creed, but Assassin's Creed Chronicles: China is a work of art on its own, featuring a traditional paintbrush-style rendering. The game is said to combine stealth, martial arts, and all-new assassin gear.

Dead Kings, on the other hand, is a brand new campaign set in the time after the main Unity storyline. As Arno, you'll travel to Saint Denis, described by the publisher as "a troubled city with a mysterious and extensive underground that holds the crypts of deceased French kings."

The DLC will also feature a new guillotine gun, new co-op missions, and brand new gear that can even be brought back to the main Unity game.

And if that's not enough to get you worked up for more Assassin's Creed, Fox has announced that it will be releasing the new Assassin's Creed movie starring Michael Fassbender on December 21, 2016.

Assassin's Creed Unity is now available for the PlayStation 4, Xbox One, and PC.
