Ubisoft surprised fans by announcing a brand new crossover between Assassin's Creed Shadows and Attack on Titan , bringing a free mission and themed content inspired by the anime. The collaboration will be available from November 25th and can be accessed until December 22nd, 2025 , making the event temporary and highly anticipated.
A mission that unites shinobi, samurai, and titans.
According to Ubisoft, the new mission begins when Naoe and Yasuke are drawn to rumors of forbidden rituals and strange transformations occurring in Yamashiro. Their investigation leads the pair to the mysterious Crystal Cave , where sinister experiments reveal a colossal threat—a clear reference to the creatures from Attack on Titan.
Guided by a mysterious woman named Ada , the protagonists must rescue a friend captured by a cult and confront an enemy far beyond what they are used to. The mission will bring new challenges, exploration, and exclusive rewards.

Themed rewards and cosmetics
Upon completing the mission, players will be able to obtain a new katana and special items hidden in chests throughout the cave.
Additionally, Ubisoft will release a set of premium cosmetics , including:
- Yasuke's costume is inspired by a Titan.
- Mikasa-inspired outfit for Naoe
- New themed weapons
- A mount based on the Survey Corps.
Paid content is optional, but it reinforces the appeal of the crossover for fans of both universes.

Assassin's Creed Shadows continues to grow
This is the game's second crossover, following the collaboration with Dead by Daylight , which also brought short missions and cosmetics. Since its release, Shadows has received multiple updates, including extra characters, community missions, and tributes to fans.
With over 5 million registered players as of July, the title remains one of the strongest in the franchise in recent years. Ubisoft plans to continue offering content until at least 2026, when it should also move forward with the highly anticipated remake of Assassin's Creed: Black Flag .

The crossover between Assassin's Creed Shadows and Attack on Titan represents an unexpected yet exciting fusion, mixing samurai, shinobi, and titans in a cinematic mission. With free content for a limited time and themed cosmetics, the event promises to energize the community and attract fans from both worlds.
