I thought Covenant's simplistic grey brutalist architecture for the Engineer city was boring as hell. One of the things that most disappointed me about the movie. All the things you could do for an alien city - especially one inspired by Giger - and they gave us that? So unimaginative.
I suspect the game won't give us much more since the movies didn't give us much to begin with. We got "room with table and drawings on the walls", "big room with heads in it" and "big open space". These ruins will be the equivalent of the Derelict from previous Alien/AVP games, just somewhere that we go "oh cool, it's that thing from the movies", only, y'know, much less cool.
