Nice ! Seems already very large, but I bet it gets much larger, and I have some reasons to support why.
some of why would be that it would in fact make a decent WRECK lore wise AND size wise.
Foundry 42 is working on it.
Big focus on FPS levels around the time it is going to be worked on.
They will most likely make it so two people can walk on all the stairs side by side and in the hallways everywhere, this will force it to become larger, also they will give you enough room to walk along the sides of any storage or vehicles, because of clipping issues and camera angles, because this is a videogame and it wouldn't look good in any presentation unless they did so.
