And on the ninth day...
Some Tremulous maps ported to the Unvanquished package file format. A few genuine Unvanquished maps might have slipped in. If you are searching for a directory suitable for download by Unvanquished clients, use this.
Copyright is with the respective creators (I guess).
There are currently 421 maps in this list. A changelog is available.
A version string like 0+b4 means: the original map has the version b4, and this is the zeroth (very first) package made from that map. I would prefer b4+0 instead, but I am told a version string must start with a digit.
