As for the other map:

There was an error in the original, so it's only hosted on one server — and they had to repack the .pk3 to get it to work. This is a complete remake of the map, new textures and brushes and all, but the layout and gameplay is more or less the same. Download here:

(if you want the original, just remove "revisited" from the above link — but it won't work unless you fix the scripts)
