I just went through the video and screen-capped any intersting and new things, and put them in a blog.
Check them out here.
The one with chief looking over the cliff looks like a Ghost is tumbling down, so i think in that cinematic we’ll see chief jumping out of one before the cliff edge.
I like the part in the video where it shows the ‘Mammoth’ driving, there was no still photos of that? :L
I saw it. but didnt screen-cap it for some reason haha.
Added it now
