I've been investigating about this things for the past few days and I haven't found anything yet.
I'm looking for the file names (or the names that you pass to the PlaySound function) of the mp and zm modes, especially the names of the songs, like the mp main menu music or the music easter eggs from zm.
Also I'm not sure how the PlaySound function works. Do I have to put it after an entity like self, player or level? What parameters does the function accepts?
