It's officially confirmed that the trailer egg pointing to Destiny and Halo developer Bungie's new mystery game is hidden somewhere in the Destiny game series.
According to Bungie game director Christopher Barrett, he confirmed that easter eggs associated with the studio's new IP are hidden somewhere in the world of Destiny. His answers, and the questions he answered, did not specifically state that this was limited to Destiny 2. But given the studio's development timeline, it's almost certain that this new IP will emerge during destiny 2's development or lifecycle.
In a follow-up tweet, Barrett playfully added that it was all just "maybe," paired with a very specific emoji: a smiling face engraved on the moon. This led some players to believe that this mysterious Easter egg was hidden somewhere on the moon, part of Destiny 1, which was later added to Destiny 2 with the release of the Shadow Fortress expansion pack.
Despite a lot of effort on Reddit, the "detectives" in Raid Secrets, the famous Easter Egg Hunter section of the Destiny community, may be completely overlooked because players don't know what they're looking for.
One player hypothesized that the Easter egg might be related to the "Matter" trademark filed by Bungie in 2018. However, the player scanned the in-game archive text and found no unusual "Matter" related information, at least not related to the Shadow Fortress DLC content.
This isn't the first time Bungie has hidden an Easter egg trailer for a new IP in its game. The "easter egg hunt" was also triggered by Barret's mention of Fate's tweet that had hidden easter eggs in Halo 3: ODST. The Easter egg didn't catch the attention of players at the time because no one but the studio developers knew what Destiny was like. Maybe in the future we will also find that bungie's new Easter eggs have always been in front of our eyes, but we just don't know.
