.Map :: MoHAA Mapping

I've been curious lately, as i'm wont to do, and have been wondering how i could add maps that would be played after the last m6 map. How would i add a button to the new game menu? how would i name it? m7l1? in that case i'd need to make a briefing or something of the sort for it right? how would i do that?

sorry for the multitude of questions, but this is a whole new can to crack for me.

Loading the next map is a worldspawn property--in the bsp file. But, it could probably be added to the script of the last map--if the credits can be disabled.

Yah just use bpstransition or leveltransition

just change the last end map to not end the game,. u cud use the global script.
And ud have to edit the urc file for the map board for more locations.
