But either way, I'd recommend changing the voices of the characters. Listening to Misty sound like Dempsey and Marlton like Nikolai is... weird.

Nice map! It looks great but it has few flaws. I saw MrDalekJD's video about this map and noticed the characters use the original crew's voices. I could give you the folder containing the audio files of the characters and possibly some ambiance sound effects of the map Town from Bo2 if you want. Just sent me a private message and I'll post the folder(s) containing the audio OR I can give you the link where I got the audio rip tool (unless you have it judging by how you already have some of the assets of Bo2).
