At Gamescom this year, Ubisoft and Square Enix revealed plans for collaborative events in Final Fantasy XV that pay homage to Assassin’s Creed Origins, the latest entry in the former company’s popular franchise. The two publishers also revealed special artwork in celebration of the events.

As noted in a blog post on Ubisoft’s site, the seeds for the unexpected collaboration were sewn during an informal meeting that took place at the Tokyo Game Show. There have been Easter eggs in promotional material from both companies ever since (see what you can spot in the new Assassin’s Creed Origins trailer embedded below), and now the teams are ready to make their mutual admiration official and interactive.

“This collaboration is the result of being huge fans,” said Ashraff Ismail, game director at Ubisoft Montreal, who was on hand at Gamescom to sign the special artwork. “There’s a lot of respect between the two teams and we couldn’t be more thrilled with the opportunity to pay homage to each other’s work.”

Starting August 30th, Final Fantasy XV players in possession of the Dream Egg (obtained during the Moogle Chocobo Carnival event) will be able to lead Noctis around his world while he is wearing an Assassin outfit. The next day, free Assassin’s Festival DLC launches for the game, transforming the town of Lestallum with banners and signs. New activities will be available, as well, and Noctis will gain abilities you might recognize from Ubisoft’s franchise.

Assassin’s Creed Origins, which unfolds in ancient Egypt, will arrive on PlayStation 4, Xbox One, and PC on October 27, 2017. No special Final Fantasy-themed events have been announced for that title, but given the love the Ubisoft developers apparently share for their competition’s work (we liked it too), something along those lines wouldn’t come as a total shock.
