Square Enix and Crystal Dynamics have released a new Marvel's Avengers update on PS4, Xbox One, PS5, Xbox Series X, Xbox Series S, and PC. Right now, there's been no word of when the update will come to Google Stadia, but we do have the update's patch notes, which not only reveal and detail the various bug fixes, improvements, and adjustments being made, but relay word of new features, or more specifically, new minor artifacts.

"To keep you warm during the winter," 2 ISO-8s and 2 Norn Stones have been added. As Crystal Dynamics notes, the former can drop from Drop Zones, while the latter will be limited to DNA Chest and the Super-Adaptoid fight.

At the moment of publishing, it's unclear if the update requires a download from players, which means it's also unclear what the size of the file is if there's a download on the aforementioned platforms. If this information is provided, we will be sure to update the story. In the meantime, below you can find the full and official patch notes for today's new update.
