Each film in the "Assassin's Creed" series is set in the same world, but it is extremely rare for the protagonists of each game to cross paths. Since we are in the age of crossovers, it is somewhat unsurprising that Ubisoft is following the trend and announcing a new "Assassin's Creed" DLC that will pit the main characters from "Assassin's Creed Odyssey" and "Assassin's Creed Valhalla" against each other.

As noted on the PlayStation Blog, Assassin's Creed Crossover Stories will launch tomorrow as free DLC. This add-on will allow players to play one storyline in Assassin's Creed Odyssey and Assassin's Creed Valhalla.

"When we looked at the recently released games and their place in the overall timeline of the world, we saw an opportunity to once again spotlight the very unique character of the Cassandra brand," said Ubisoft Quebec said Clémence Noglix, Associate Creative Director. Her immortality began in 431 BC, and the concept of her connection to the rest of the game began there. We needed to begin her new journey, which is in a way a unique odyssey, by asking the question, 'What did Cassandra do when she became immortal? So we started with 'Assassin's Creed Odyssey,' and since 'Assassin's Creed Valhalla' was a recently released game, it was an opportunity to bridge the two and answer the question, 'What happens when two Assassin's Creed protagonists meet?'"

The DLC "The Hidden Treasures" begins with Cassandra initially relaxing after the events of "The Odyssey," but an event forces her to end her rest and go on a treasure hunt. This journey continues in Valhalla's DLC "Fatal Encounter," in which you play as Eivor, the protagonist of that film. In true crossover style, the two heroes will join forces to confront the (presumably) real threat after an epic battle, and the difference in experience between the two warriors should be a highlight.

"We had to keep in mind that Cassandra is more than 1,300 years older," says Nogrix of Cassandra and Avor's first encounter in the crossover. 'She has traveled the world and seen the rise and fall of the Roman Empire.' She has traveled the world and seen the rise and fall of the Roman Empire. We wanted the player to feel that she has learned and seen so much, yet her mind has remained the same. It was a challenge in a way to pay attention to each hero's personality while still allowing both of them to show their abilities on the battlefield. The team did a great job with that encounter scene."

Assassin's Creed's Crossover Stories will be available on PS4, PS5, Xbox One, Xbox Series X/S and PC on December 14.
