I'm getting claustrophobia just looking at this!
It's a complex layout of lots of small chambers and twisty passages, patchily lit and with great potential for an exciting underground investigation whatever genre of game you are playing. Modern and even future games may well include this kind of structure - just imagine creeping around one in your spacesuit!
There is a single page overview and segmented miniatures-scaled versions with hex grid, square grid or no grid in the PDF, and giant single-sheet JPGs for virtual table top users (or those with access to poster-printing facilities). The high standard of almost photo-realistic crisp art that we've come to expect from DramaScape is displayed, with lots of detail down to smashed coffins leaking bones over the floor.
Accompanying text gives a verbal description of the complex room by room and also some suggestions for how to use it in your games, all fantasy-themed.
My only quibble is that half the fun of dungeon-crawling is not knowing what is around the next corner, and this battlemap's design makes it quite difficult for the GM to reveal it stage-by-stage rather than all at once.
