I found this map in ns mapping forum and looks to be a fun map with bots so I did a quick waypoint job on it. It's not one of my best jobs and I have not tested it but should be playable never-the-less.
The map can be found here: NS forums/all ns maps
PS: This map does appear to come with a waypoint file but it is blank, don't use the waypoint that comes with ns_blackmesa.
