Originally this was going to be a hl2dm map, but technical limits on my laptop forced my hand into only creating this for hldm. Based on a part of the building where I(used to) work, this will be a medium map. A mainly indoor, multilevel playing field.
Preliminary brush work is complete, but lots of tweaking yet to be done. Textures and lighting barely started.
I'll post screenshot when I get a bit further finished. You can find more info (and my other maps) at my website.
