For EVERYBODY who keeps asking for these maps to be ported to Gmod, I'm saying this to let you all know: they already work in Gmod. I've been using them for a while now and they work just fine.

There are a few issues: there's no lighting, everything's scaled up a big large for normal ragdolls, and all props in map have no collision. But the floor and walls do, so for simple scenebuilding purposes, these things work just fine. Just need to port them over manually, add lighting yourself, and you're good to go.
