Chief's Forerunner powers finally activate?

In the new cinema first look trailer, Chief creates what appears to be a large energy explosion by ground pounding.

Here’s a still from the trailer.

So the question is, did John acquire some kind of advanced Forerunner tech during his disappearance? And does this new ability have anything to do with the awakened imprint/accelerated evolution?

that’s not chief that was that warden eternal that was in that e3 demo

Yeah, that was the Warden. Not Chief. And there’s no such things as “Forerunner powers”. It’s just technology.

-Yoink- that. I’m cancelling my preorder if the Chief can’t Devil Trigger.

I like you.

This is just… what? Are you still following the whole “Chief is Bornstellar” theory?
