Thanks for these great images.
On the side, it looks like retractables armor plates ala stargate helmets if you see what i mean.
Might be the chair in sleep mode, could be the Engineer's cryo/hypersleep rack.
Or maybe it's just empty.
The other thing i can clearly see in this images is that Giger's designs has been muted into something more slick, more mechanical than bio.More simple even...
