The much troubled Assassin's Creed Unity will be getting a new, free DLC called "Dead Kings" which will have Arno exploring a new portion of France.

In this CG trailer, we see Arno shortly after the French Revolution thinking about the past events and how the country is healing but he isn't. After killing some thugs who seemed to have been paid off by Napoleon Bonaparte, Arno descends into a hidden underworld which has many secrets buried by the French kings.

The city of Saint-Denis is an ancient necropolis has an "intricate network of catacombs and deep caves that hide the best-kept secrets of the French kings," according to the YouTube description and is said to be "extensive."

Assassin's Creed Unity - Dead Kings DLC will be free to anyone who owns the game on PC, PlayStation 4, and Xbox One on January 13.
