[WIP] Necropolis

A long term project to introduce an endgame structure/dungeon.  To find it, search for 'salon' on the worldmap.  For now, I need feedback on whether the sewers are too labyrinthine.  The minimap will all be revealed so try to avoid looking at it while you wander the sewers... just take a crowbar and a bunch of wearable flashlights.  Start at the water pump station in the northeast and enter the sewers.  Try to find the vault entrance.

z   Town, still needs monsters,vehicles, and item touch-ups
z-1  Sewers, still needs monsters and items
z-2  Vault LV1, architecture[75%]
z-3  Vault LV2, housing
z-4  Vault LV3, utilities/reactor 

This is far from completion; for reference, the old largest fixed building was the 9 tile (3x3) mega-stores.  Then we went to the 81 tile (9x9) mall.  When completed, Necropolis will occupy 405 world map tiles (9x9x5)... not all of those will be packed but I'll do my best to keep them interesting.
