Raw, early, and fairly rough, renders of the Engineer City's overall layout. From an insider at 20th Century Fox.
The Engineer City is approximately 2 kilometers (1.2 miles) wide. The only things that seem to be missing are the amount of buildings around the City's center, and the Heads carved into the mountains. With a width of 2km (1.2 miles), you would think this would be more of a town, or an outpost, than an actual "city". Than again, our pale friends seem to be practically immortal, so who needs more space right? Just seems pretty small for a city.
I hope this helps anyone who wants to make a basic map of the Engineer's city/town/outpost/general store/bar/tavern/rest stop
Note: I did not obtain this.
