Well, I don't really how to name this dungeon .. but it's not important. I call it Demo Dungeon because it is the first dungeon entirely done with DMbuild, so you can view it within the editor. Of course you should prefer not to do this if you want to play it.
Here you'll get 2 versions of a 4-levels playable dungeon. One is for DM PC, and the other is for CSB4Win.
And a stupid number: this dungeon contains in 4 levels more actuators than in the original 14 levels DM dungeon!
