Almost eleven years after Ubisoft introduced its tactical shooter, the upcoming Tachanka DOOM skin offers an interesting example of how Rainbow Six Siege X is expanding its identity. Following Solid Snake’s arrival as a playable operator, Ubisoft is taking a different approach to its collaboration with id Software. This time, the guest character is not expected to have a place of his own on the operator roster.
The Tachanka DOOM skin already has a release date
On November 15, 2026, Ubisoft surprised players with a short video announcing its next crossover. Lasting approximately seven seconds, the footage reveals a pair of armored boots surrounded by smoke and red lighting. Little else appears on screen, leaving much of the collaboration to the imagination.
Nevertheless, the official Rainbow Six account on X confirmed that the crossover will arrive on December 22, 2026. According to TheGamer, the teaser also features music by Mick Gordon, the composer behind DOOM (2016) and DOOM Eternal.
Although Ubisoft has yet to showcase the cosmetic in detail, TheGamer and other outlets report that the Doom Slayer will appear as a legendary skin for Tachanka, one of the game’s Defenders.
Why the Tachanka DOOM skin differs from Solid Snake
One particularly interesting detail about this collaboration is its format. Whereas Solid Snake from Metal Gear Solid joined Rainbow Six Siege X as a fully playable operator, the Doom Slayer is expected to arrive exclusively as a cosmetic transformation.
The distinction matters because introducing an operator and releasing a skin are two fundamentally different approaches to crossover content. The former expands the playable roster, while the latter allows Ubisoft to experiment with its visual identity without necessarily introducing new gameplay mechanics.
Furthermore, Siege is not the only military shooter to recently welcome id Software’s franchise. Call of Duty: Black Ops 7 received its own DOOM collaboration a few months ago, illustrating how the demon-slaying series can find a place in shooters with very different gameplay philosophies.
Two very different sides of Rainbow Six Siege X
The timing of this announcement is particularly noteworthy. Ubisoft revealed the crossover on the same day it presented Operation Vital Signal, Year 11’s fourth season, which launches on December 1.
Alongside Doc’s remaster and his new E-HEAL Monitor, the season introduces separate Solo/Duo and Flex ranked queues. These changes contrast with the purely cosmetic appeal of the DOOM collaboration.
Moreover, with FaZe Clan’s victory at the R6 Major Osaka, competitive Siege remains another important part of the game’s current identity.
However, not everyone welcomes its increasingly unconventional collaborations. While many players consider the upcoming crossover one of the wildest in Siege history, others believe Ubisoft is moving further away from its counter-terrorism roots. The debate ultimately raises a question about whether tactical gameplay and extravagant cosmetics can comfortably coexist.
What remains unknown about the Doom Slayer crossover?
For now, Ubisoft has not announced the price of the legendary skin, how players will unlock it or whether additional cosmetic items will accompany its release. Consequently, any details concerning its availability beyond the confirmed release date remain uncertain.
Originally released on December 1, 2015, Tom Clancy’s Rainbow Six Siege is approaching its eleventh anniversary. The tactical 5v5 shooter is currently available on PC, PS5, PS4, Xbox Series X|S and Xbox One.
Ultimately, the Tachanka DOOM skin represents another chapter in Ubisoft’s evolving approach to collaborations. But how far can Rainbow Six Siege X push its visual identity before it feels disconnected from its tactical origins?
