Ive been up close and its not Octagonal its round. There arn't edges.
It does have smaller eyes around the main eye.
I believe its Thargoid/Human related or at least a Carbon/ammonia life form.
A guardian of the barnacles or Meta Alloys
It's not 'octagonal' in the sense that it's got a more organic design this time with the new graphical possibilities but they got around not having defined edges by using an 8 fold rotational symmetry around the central axis.
Also, around the central circle which sort of looks like the underside of a mushroom, there is a definite octagon.
Additional info: I'm pretty sure there are four 'claws' or 'blades'. One is wedged into the ground right next to another lying on its side. One is pretty far away from the others. These 'claws' as I like to call them are all in one piece, other than the fact that they got ripped apart from somewhere. I believe these to be the 'landing gear' or more like 'latching onto stuff' gear.
The wing shaped parts definitely have some kind of airfoil design to them, suggesting they may aid the craft in atmospheric flight. I couldn't have a definitive count on these parts as they seem to be broken in different pieces but it seems like there are also four of these wing shapes.
The overall craft may very well look like an octagonal central body surrounded by four wings and four claws alternating.
We'll have to wait and see unfortunately. Mid October can't come soon enough!
