Oh yeah. He's definitely not on Earth anymore. As for what the Alien Robot Angel of death is, I'd say the War Sphinx is definitely in the right direction. Still curious who would be piloting it though. I mean if the Didact is dead, who else could possibly be left?
And I still want to know why the Chief is walking around the desert alone wearing rags over a badly-damaged MJOLNIR Mk VI (and why wasn't he upgraded to the Mk VII when he got back to Earth?)
Things aren't adding up with this video and where we left the chief at the end of Halo 4...
Dude. That Halo 5 trailer. What if the thing Chief encountered...is one of the Didact's war sphinxes? I want to believe that MC is on Earth, but that backdrop with the orangish planetoid thing hovering about is making me doubt that.
