This music and map are required! Must... have... Must... use... music in mission.... must fight Gorn!
Also it would be neat if we could make custom "for that Foundry mission only" items. Like say in a mission I could do some mission objectives (example: Getting minerals) and get a reward that lasts ONLY for that mission that is a homemade cannon used to kill a boss.
right now I don't know if a way off hand to link a music track to a location, beyond a fight brings on the fight music. Now it is possible that there is something nifty with the Colosseum map that will do this, but it would be a background thing that we wouldn't be able to control. Besides whats the point without a wooden bazooka?
