The following are some indexes of the map database used on my servers.
This is a text-based list of maps which can be used with the callvote command on my servers. It includes the game type and CTF support status of each map.
This is a package of the levelshot thumbnail images for each map. It contains the same maps as the text list file but as a set of jpg images, which can be viewed in the Windows file browser or other image program.
Here is a list of the map pk3s available for download from my server. You can use a script or download manager to download all of them if you want the entire archive.
