how to play custom maps?

[Gibstick]

If you haven't added bot waypoints, loading your map in a bot mode will do so for you (flood the entire map with them, not very precise). Just type

[SELECT ALL] Code:

/mode 8; map (mapnamehere)

Mode 8 is for bot deathmatch, you can lookup the other modes on the wiki.
Then you can /addbot
