Square Enix and Ubisoft have partnered to release a limited time event for Final Fantasy XV. Called Assassin's Festival, the event will combine the gameplay elements of the Assassin's Creed series into the Final Fantasy XV city of Lestallum.  The event will be free to access from August 31, 2017, until January 31, 2018. The Assassin's Festival will also provide unique mini-games and the opportunity to unlock unique items, including Medjay Assassin's Robes for the playable cast.

Additionally, a Master Assassin's Robe will be available for an even more limited time via an item known as a Dream Egg from the Moogle Chocobo Carnival event, which will run through late September 2017. Final Fantasy XV is currently available on PlayStation 4 and Xbox One. A PC version was recently announced alongside a reworked mobile version.
