I've included the FMOD plugin that imports FMOD Studio projects into Unreal Engine. From what I've read this will let me create dynamic audio events for game sequences. For the soundtrack I'm going to customize and mix in this: https://soundcloud.com/benhog/revisions15

I'll update the rest of the sound effects as well. FMOD has way more than I need but it's free for small games, so why not?

UPDATE on the cheap servos. One has already died which I expected would happen during use, but these have been sitting mostly idle so I'm not sure what happened. I've got three extras left...
