Act of Genesis Stance?

Hey everyone,

Has anyone found out what’s going on with this stance? Says it’s unlocked in campaign but no one seems to have figured it out yet. Could it be locked behind future DLC? Or maybe it’s like the IWHBYD skull in Halo 3?

Thanks.

I haven’t got this stance yet either
I don’t know how to get

No clue, I’ve checked multiple sources, it may be bugged or locked behind some easter egg or DLC as you said. It’s the same for the requiem revengeance stance and the Infinity weapon charm. Unfortunate, they look so nice as well!
