multiplayer multimap?

is it possible to make a multiplayer gmae that when its finished you are taken to anuter map with all player in same player spots?

also is it possible to make that the game wont start unless you got some outer map in your archive (the game will simply end if not all players got all maps)

if you can do these things then how?


i jest think t will be a fantastic thing to make a multiplayer campaigen and these 2 things are needed to make them.
