Use the drop down boxes at the top limit the maps to what you want. For example: if you maps that contain: 1 SotM and 1 TJ, then select "1" in those dropdown boxes and "0" in all the others. Once you have a list of maps meeting your selection, you can go to the "data" tab and find the map (they're in alphabetical order) and use the link there to go to the map download.
Version 1.0 I copied the database from GameBears site on 09/05/08. I'll try to make updates to this on a frequent basis if people are using it.

Maps added since last update
Battlefield of Valhalla selection criteria
Sorry for the long time between updates
Version 3.0 updated on January 20, 2009 based on updates to GameBears site.
Maps added since last update
3-person maps check (note: not many are marked 3-player, so this may not be 100% reliable)
As an engineer, I love this kind of stuff! I don't know if GameBears has this info or not, but number of players would be great info also, I play a lot of 3-player games and good maps are hard to find. Once again, great tool.
