Fifield's Pups
On December 25, 2093, Sean Fifield deployed Weyland Industries Spectagraphs into the pyramid on LV-223.
The "pups" quickly mapped the cistern, multiple levels of tunneling, and rooms of various kinds. One room in particular was mapped by the Spectagraph and was found to have a large ornamental head and scores of upright urns. There was an additional "head" room on the scale diagram of the pyramid on LV-223, above.
This additional head room remained unmapped due to the door remaining closed, below.
I believe there are 6 Spectagraph "Pups" in the below map (Photoshop filtered to bring out detail).
Fifield and Millburn

That Concept did show there are more than ONE of the Big Head Rooms.
But it was hard to make out via the Holo-Maps
Here is some Close Ups i did for another Topic a while back with a Layout of the Complex ;)

Strange how this shown in fractions of seconds during the movie. Good eye!

Remember when Gearbox Software and SEGA included the 'pups' inside the derelict, obviously assuming before the movies release that they were Engineer/Space Jockey technology.

Thank you for the topic enrichment Gavin.
I had no idea what you were talking about and it was interesting to research it. We focus quite a bit on the content product but there is just as much drama in the development of the games, films, tv...below.
