UPDATE 2/12/22: Ubisoft has now officially confirmed its Assassin's Creed and Destiny crossover event, which will see sci-fi armour for sale in Valhalla later this month, as well as AC styles in Destiny 2.
The collaboration will go live on 6th December, when Destiny cosmetics themed around Lord Shaxx and Saint-14 will become available to buy in Assassin's Creed Valhalla. Assassin's Creed-themed items - I can see an Apple of Eden-style ghost shell! - will then go live via Destiny 2's Eververse shop.
One final note from Ubisoft confirms a free weekend for Valhalla is on the way. You'll be able to dip your toe into Eivor's Viking adventures for no cost from 15th to 19th December.
ORIGINAL STORY 1/12/22: Ubisoft's final update for Assassin's Creed Valhalla is now available - a little earlier than expected! - and contains one last serving of story for those looking to see off heroine Eivor in style.
There are still a few surprises left in store, however - as spotted by Destiny dataminer MAK Moderator - including armour sets themed around Destiny and Monster Hunter characters.
Destiny's Crucible boss Lord Shaxx and Saint-14 will both see their armour sets recreated in Valhalla. There's also an armour set designed to look like Monster Hunter's Odogaron.
These upcoming designs are not yet available in Valhalla, but will likely be announced and made available to purchase via its in-game store in the future.
You can take a look at them - and a few other unreleased cosmetics - in the video below.
This isn't the first time Assassin's Creed has offered crossover cosmetic items connected to other video game franchises. Memorably, the Ancient Egypt-set Assassin's Creed Origins included a Final Fantasy crossover that let you ride around on a Chocobo.
A few months back, dataminers discovered Iron Man and Thanos armour sets in Valhalla as well, which we're also still to see release.
With Valhalla's content updates now over, it's likely we'll see Ubisoft drip feed these new skin launches as a way to keep people popping back into Valhalla until next year's Baghdad-set Assassin's Creed Mirage arrives.
As a reminder, this week's final content update includes several nice set-ups for that game - including an unexpected appearance by Roshan, your mentor in Mirage, voiced by the brilliant Shohreh Aghdashloo.
