TO add a map add the map to the "maps" folder.
THe extension should be map.bsp.
The waypoint is a seperate file and the map requires it for the bots to work on.
Put the pwf files in the podbot/wpdefault folder.
Many sites allow waypoint downloads, like bots-united waypoint forums,
www.cs-maps.org and
www.cfegames.com also some map downloads in
www.fpsbanana.com has waypoint in them.
Search google and this forum for your map and waypoints.
Ex: aim_ak-colt waypoints.
