The Destiny 2 Shadowkeep Collector’s Edition has a crazy physical puzzle that’s also a piece of a large puzzle that’s dependent on the entire community to solve.
The Collector’s Edition came with a real-life Cryptoglyph, mirroring a very important in-game one that’s used with Cleansed Essences. This real life Cryptoglyph is a puzzle in itself, requiring a combination to unlock (unless you just want to brute force the thing and potentially break it. If you don’t know how to open your Cryptoglyph, there are instructions to do so right here.
Once open, the Cryptoglyph will present its owner a URL to retrieve up to five images, each importantly useful in solving five larger images that the Destiny community is sure will lead to some further loot. At present, the Destiny Raid Secrets subreddit has gathered most of the images needed to form the five final pictures, but work is still ongoing.
Destiny 2 Shadowkeep is currently available on Windows PC, Xbox One and PS4.
