You want to fit a Blood Asp into a house? 
i could . . of course, the house would not be STANDING . . the walls would more or less be leaning on the blood asp inside . .
or he would wear it like a jacket . .
but i was thinking megalomaniacal gigantic industrial complexes . . like dropship hangars or something like that . . or mech factories . .
or maybe ISHIYAMA! the Kuritan Solaris VII Arena. it's basically an old mine that has been outfitted for mech-combat in near total darknaess and as close in as it gets with mechs . .
and still there's open spaces and jumping possible on one location, namely the deep chasm or big gallery where all of the shafts meet in the middle on several levels . .
and i think the marik arena is basically a huge factory . . with a ring of molten lava between the inner and outer ring . .
and there was one map for MW4 Mercs that had the Davion Arena, i can't remember the name right now . . big huge frigging map with some buildings and levels interconnected by walkways in mech size . . kinda like the old DM-Deck13 for UT . . but looking better and having a volcano and i think an ice corner somewhere . . the buildings you could climb onto with your mech allowed you to get higher than was possible with jumpjets . . so you could jump DOWN, but not UP without getting some levels up before jumping anyway . .
an indoor map like ishiyama would be a slug-fest for LB-X and SRM's and pulse-lasers, that's for sure . . no big team tactics, no hammering single mechs with concentrated fire from whole lance, no pop tart sniping . . only going in and hoping the vague sheme in front of you is an enemy mech and the shadow behind you is not . .
