Soundtrack - Nightbird Lost Wing ( Rock Remix) (Nekomata Master)
Found in the files of the game's PC version. There is an unused more Rock oriented version of Air Ship Convoy Act 1. This goes in line with many of the other stages that have one act with a Rock oriented theme and another with a more electronic take. However for whatever the reason, this particular stage embraces the more electronic take.
