Ubisoft has confirmed Attack on Titan as the next big brand crossover coming to Assassin's Creed Shadows, with a free story quest and paid cosmetics arriving this week.

From tomorrow, November 24, players will be able to take on a new free mission and purchase a series of in-game items. But you'll need to act quickly, as the Attack on Titan mission content will only be live until December 22.

Hit anime media franchise Attack on Titan is the second crossover for Assassin's Creed Shadows following the game's earlier Dead by Daylight collaboration. Similarly, that offered up a simple mission (which lasted around 15 minutes) and then let you pay to adorn Shadows' main characters in themed cosmetics, if you so chose.

A series of other, non-crossover story missions have also been added to Shadows for free since launch, one of which starred Critical Role's Robbie Daymond as a new character you can recruit as an ally. Another update, which arrived in late September, immortalized a fan's beloved pet cat. Fans expect Ubisoft to continue supporting Shadows with further content through 2026, as it also prepares its long-awaited (but still unannounced) Assassin's Creed: Black Flag remake.

Last week, Ubisoft celebrated its latest set of financial results which it said had been driven by a "strong performance" for the Assassin's Creed franchise. But while there was an update on how many people had played 2023's Assassin's Creed Mirage, Ubisoft gave no further update on how Shadows has sold. Back in July, Ubisoft said Shadows had surpassed 5 million players, and that its performance had been in line with expectations.

Assassin's Creed Shadows is currently half price in Amazon's Black Friday sale.
