In a move that few players anticipated, Ubisoft has officially brought the iconic anime Attack on Titan (also known as Shingeki no Kyojin) into the world of Tom Clancy’s Rainbow Six Siege. Released in late December 2025, the collaboration introduces anime-inspired cosmetic content that blends the intense, dramatic imagery of Attack on Titan with the tactical, close-quarters gameplay of Rainbow Six Siege. While the crossover does not alter gameplay mechanics, it has quickly become one of the most talked-about and controversial collaborations in the game’s history.

The collaboration focuses on premium cosmetic bundles that reimagine two Siege operators as figures inspired by the anime. Amaru receives a bundle modeled after Mikasa Ackerman, featuring a uniform and headgear styled to resemble Mikasa’s signature look from the series. The bundle also includes a custom weapon skin, an operator card portrait, and a themed charm, all drawing heavily from Attack on Titan’s visual identity. Amaru’s fast, vertical movement makes her a natural thematic match for Mikasa, whose combat style in the anime relies on speed, agility, and aerial maneuvering.

On the defensive side, Oryx is transformed into a representation of the Armored Titan. His bundle features a heavily plated, Titan-inspired body design that emphasizes strength and brute force, along with a unique weapon skin for the T-5 SMG and a matching operator card and charm. Oryx’s ability to dash through walls and overpower enemies aligns closely with the destructive nature of the Armored Titan, making the visual concept surprisingly fitting despite the drastic stylistic shift.

Both cosmetic bundles are available for purchase using R6 Credits, either individually or at a discounted price when bought together. Unlike limited-time events that disappear after a short window, Ubisoft has confirmed that these items are permanent additions to the in-game store, allowing players to purchase them at any time. This decision signals confidence in the collaboration’s long-term appeal, even amid divided opinions.

One reason the Attack on Titan bundle may be controversial is that it clashes with Rainbow Six Siege’s original identity as a grounded, tactical shooter. The game was built around realism, military authenticity, and immersive counter-terrorism scenarios, and highly stylized anime cosmetics can feel out of place in that setting. For longtime players, seeing operators dressed as anime characters can break immersion and make the game feel less serious, raising concerns that Siege is drifting away from what originally made it unique.

At first glance, Attack on Titan and Rainbow Six Siege appear to be an unusual pairing. The anime is defined by towering humanoid creatures, apocalyptic themes, and stylized action, while Siege is rooted in realism, military tactics, and methodical team play. However, this crossover fits within a broader trend for Rainbow Six Siege, which has increasingly embraced pop-culture collaborations in recent years. Previous crossovers with franchises like Resident Evil, Money Heist, and Rick and Morty have already pushed the game beyond its original grounded tone, making Attack on Titan a bold but not entirely unprecedented step. 

As developers seek to attract wider audiences and maintain long-term engagement, crossover content has become an increasingly common strategy. While these collaborations can generate excitement and introduce new players, they also risk alienating longtime fans who value consistency and atmosphere.

Ultimately, the Attack on Titan and Rainbow Six Siege collaboration stands as one of the most daring and divisive cosmetic releases the game has seen. Whether viewed as an exciting fusion of two beloved franchises or a step too far from Siege’s tactical roots, it has undeniably sparked conversation and attention. For fans of both the anime and the shooter, the crossover offers a visually striking experience, while for others it serves as a reminder of how much Rainbow Six Siege has evolved since its original release.
