It seems that the Halo Infinite E3 2019 trailer contains a QR code that leads up to a Cortana audio clip.

　　As found by Twitter user Xepyal, that trailer that Microsoft and 343 Industries released more than a month ago, apparently contains a hidden QR code. When scanned, the code links to an audio recording featuring Cortana. On social media, fans are already speculating whether this clip is related to the ‘old’ or a new Cortana.

　　Another interesting tidbit is that the link’s URL could contain coordinates. As expected, fans have already tried to figure out where these coordinates lead to. “If I've done this right (fingers crossed ?), converting XYZ coordinates to standard LLh coordinates (using this), and assuming it's Earth: It's basically pointing close to the north pole and then down toward the center of the earth”, ResetEra user VorpalNonsense wrote. “The final destination being about 14 kilometers shy of the center of the Earth.”

　　“89°59'59.9"N 72°15'19.2"W

　　6356.75 kilometers deep”

　　An interesting find for sure and we can’t help but wonder if 343 Industries has hidden any other Halo Infinite codes in the trailers and screenshots that have been released so far.

　　Halo Infinite is slated for a release next year.
