Halo Xbox One Concept Art

I have looked at the image a few times trying to get ideas and I keep coming back to one observation… The dust in the air? It seems to remind me of the look of the dust in the air when the flood arrived on earth during Halo 3? Any thoughts?..

I tried to look for some information but i only “find” this: http://sdrv.ms/1iJiWeG

Yeah based on this, I personally think that its a new location such as a new UNSC base . Seems to have a “dark” mood to the image?.. When analyzing images… look for mood or “depth” clues within the image. I hope this next game will have a different mood to it…
