I started on May 11, and have been working mostly on weekends since.
I’ve orangemapped (or just built in nodraw) about 80% of the layout (nearly everything but the sewer and area between the room with the sci/[sub][/sub]guard and the end), and gotten what’s there pretty much playable and a decent amount of it detailed. Also various models of various levels of importance (satellite dish, custom-fit railings, stuff like that) and little variants if BM textures/models that fit the area or its brushwork better.
