This is yet another one of my "Doom-style" maps; two key things about this map are (1) it's a boss map, and (2) it has the mother and father of all Doom-style stair-builder effects. (There are literally hundreds of stairs that rise, and a bunch of other things happen at the same time...I hope that this map still qualifies as a Doom-style map, even though it would break the vanilla Doom engine in multipleways. Not that that has stopped me in any of my previous "Doom-style" maps or anything...)
