dm_residential is a map centered around a 3-way intersection in a residential neighborhood, with a hill and seven accessible buildings in the vicinity. It takes place around early morning (or late evening); most of the lighting in the level comes from streetlights and building illumination. All of the accessible buildings have their own interiors and several ways of entry and exit, providing many potential routes around and throughout the map.

Beta 3 was released on August 8, 2007. The final version, assuming all goes well, should be released in a few weeks (almost surely before September) with only some minor tweaks to the beta 2 design.

You can check out some discussion and work-in-progress screenshots in the forum thread (see below). Thanks for looking!
