Making a map

Are there any good add-ons that will allow me to make decent indoor maps with ease? Preferably similar to UDK’s “subtractive” editor. Here is an example

Never mind, I figured I would get a similar enough experience by extruding and flipping the normals.

unfortunately, no. But im sure very soon in the future someone is going to develop that add-on, and game making will be just that much easier :wink:
