The custom game option has been updated to accommodate the newly introduced monsters from the latest expansion, but it doesn't seem possible to select the new audiofiles that play on those maps for custom games. It'd be nice if we could use the background noise from the expansion or even the music added for the expansion for futuristic maps. Additionally, I'm rather fond of the music that pays during the expansion maps, but after a while it seems to stop playing without looping. It'd be nice if there was an option to make the music loop, so things don't become silent after a few rounds. I'm sure Cardotron's perfect silicon brain is capable of making the music loop!
Yeah, I'm surprised that the issue of battle music not looping hasn't been addressed. There also isn't music for campaign. It's really weird in MP when the music just stops.
What we really need is the ability to embed a custom music file into a scenario or something. I would be so much more interested in custom scenarios if I was making my own theme music for them
I've added the Citadel audio to the custom game dialog. I've also added an option to pick music for a custom game.
