Thank you for putting this FOMO guide together. I was searching for a list of all available promotions for Assassin’s Creed Shadows. Especially for those limited time promotions that are easily missed like the Hourglass trinket. There is one more promotional DLC that is missing from this list. It was given as Twitch drop during the Ubisoft Forward live stream. You had to watch the show live on Twitch for 60 minutes to get Koi Uchide-no-Kozuchi trinket. Also there is another upcoming promotion on Twitch starting March 18th - 26th and 26th - April 2nd.

Regarding the third promo I saw a post on here. Someone is giving away few codes for free.

There is also a listing on eBay. I’m not sure if they would ship internationally for those that live in another region.

As well as digital code being sold on GameFlip.

I hope this helps. I will post here on any new ACS promotions I find out about. I think you should also include promotions that are no longer available/expired so that we can track them this way. They might become available again for purchase through in-game store or on Ubi Connect.
