In an apparent homage to Assassin’s Creed, Final Fantasy XV has an assassin-based DLC, which you can get for free right now on the Microsoft Store.
It is not a permanent DLC–it gives you access to a “festival” that lasts through January 31, 2018.
I’m near the end of the game, so I’m not sure how the DLC works in that case. Either way, I got it.
The Assassin’s Festival is underway for a limited time! The tales of a mythical hero who fought to resist the shackles of oppression date back generations in Lestallum, where a festival is held in honor of the lore. As an avid fan of the spirit this local legend inspired, Noctis drags his friends along to take part in the festivities, but he also encounters a few unexpected guests… The festival ends January 31st, 2018.
