The original version, made by Stuart "Combitz" Buck, was quite popular on the DC server, but the map was a bit on the ugly side. It also had severe collision problems with vehicles. This was fixed with lots of blocking volumes and with the "simple karma" collision fix for large meshes.
Changes:
Zoned the map.
Got rid of the uglier meshes and textures, like the tv with the weirdly distorted woman and the static backdrop behind the window.
The original textures had lots of ugly black lines, smudges and glare on them. I replaced or edited the majority of them. All of the appliances textures were redone. Brand new fireplace too.
Set up shaders for surfaces that should be shiny, like glass, metal, tiles, floors etc.
Lighting completely redone.
Jump pads moved around or added for better navigation.
Turned collision off on small meshes, like wires and the guards on the stove.
Tried to make SOME sense of the pickups. Replaced the 100-something vials and 20 or so health packs with a much smaller number of gum packs (25 hp, super heal like vials.) I also made a new, higher resolution texture for the gum.
Added adren in the form of lollipops (15 adren.)
Posts on the banisters were spread out farther, and another slot track added to make the walkable surface wider.
Music track set, and music switches set up in the wall (press E to activate.) Two of the tracks are included in the zip.
