\map? is that a command of some sort?
put "/map " in console, then press tab. (do not forget to put a space right after /map
)
This will bring up a list of all your maps.
You then find one you like, and type "/map <mapname>" and hit enter.
you will now be loading up that map in an offline skirmish
If you are unsure how to bring up the console, you press the tilde key(~) it should be right beside the 1 key.
