Yesterday at PAX East 2019, Gearbox Software finally announced Borderlands 3, but also left a lot of things unsaid. The most pressing question is simply, “When does the game come out?” as no platforms or release date was revealed. Well, eagle-eyed fans may have discovered a clue in the game’s debut trailer.

Gearbox clearly loves Easter eggs, the Borderlands 3 teaser was nothing but one long Easter egg, and it seems the latest trailer has some as well. Redditor Zottelpanda noticed the somewhat-conspicuous digits 01 and 10 on the side of buildings at the 1:40 and 1:52 marks (check out the images, below).
