The video is behind the jump, here's a cool new image of Starbase Yorktown's defence turrets to enjoy, even if you go no further:
Still here? Ok, don't say I didn't warn you!
So, Krall was a Human! Looks like he arrived on Altamid aboard the USS Franklin. And then as he sees it, was abandoned by the Federation:
The Federation do not care about us. They abandoned this planet long ago. You'll probably never see me again. But if you do, be ready.
It looks like our heroes discover this in logs aboard the Franklin.
Also new in the trailer, some pretty shots of Altamid.
Another view of the Enterprise in the swarm attack. Note the really cool red windows from the red alert lighting (although kind of giving your alert status away to an opponent? - I guess they can tell if you raise shields and arm weapons anyway).
And a mysterious dark pool of something.
