UPDATE: For now it's not possible for me to add a custom round theme for NukeTown Zombies nor Die Rise (Die Rise, just play BO3 ) since both maps share the same sound as TranZit.
For this reason, I will just post the NukeTown variant audio until eventually I am successful in adding them in this mod.
ROUND START - Google Drive
ROUND END - Google Drive
Then later, I'll release a version of the audio files, that replaces TranZit's music transitions with this.
