Very very cool thanks. As everyone said, need to see in HD.
Didn't pick out any creatures.
Nice nod to the ALIEN grabbing Brett in there. Except in this case seems to be the own guys arms clutching at his helmet. Reminiscent all the same.
My favorite bit is the Space Jockey chair emerging. And I like the little stop in the trailer before it hammers back in.
I'm thinking the Inception horn thing might be sampled from the elevator in ALIENS. Or it might be the self destruct noise from ALIEN. It's not an instrument anyway.
Oh and at 37 seconds there is something dead centre at the bottom of the screen. Looks like a head, it moves anyway. Looks like it could be MR Jockey.
