You can import sounds into your map and use the MyLevel Package. That's how I got the song 'Katyusha' playing on the phonograph in my old Voronezh alpha map . No need to distribute separately, I would think
Eh, it was if other people wanted to use the sounds for urban fighting. It might be better if I included them in MyLevel, I'll see.
HH, not too sure about about actually showing the Katyusha rockets themselves. It is probably possible using emitters, but the map is already emitter intensive as it is and will only become more so as tracers and muzzle flashes are going off everywhere. If it becomes feasible, I will *try* to get them in beta 2, so we'll see.
