Two months have passed since E3 2019 and the latest trailer for Halo Infinite debuted on Xbox’s stage. For a while, 343 Industries has been dropping teases and saying that there’s more to find in a new “Discover Hope” trailer. Of course, it’s full of easter eggs and nods to Halo series, however, we weren’t expecting a secret audio message from Cortana.

Did you catch it? No surprise you didn’t… The secret message was hidden in the Master Chief’s UI that you can see in the trailer at 3:33 timestamp. If you look closely, you’ll see a stretched QR code which can be rearranged and scanned. The scanned QR code leads to a URL containing a 40-second audio file in which Cortana says: “This…this is part of me. I don’t know why. I don’t know how…but it is me.”

This hidden message was first found by a Twitter user Xepal who tweeted at 343 Industries. The official Halo Twitter account responded with a gif from the same trailer in which Halsey says “Took you long enough”.

We don’t know about you guys, but these secrets are super fun for us. We hope we’ll get more easter egg hunts as Halo Infinite launch window approaches. The game is set to be released sometime in 2020.
