DUX is now done. Producing and releasing this game can take about two weeks.
All pre-orders getting a small sticker as a bonus, and all pre-orders that get an poster are also getting the standalone OST as a bonus. Btw, on the Original Soundtrack that comes with the LE you can find an exlusive outtake tune and also three re-arranges from the Obvious Soundtrack.
Thanks for your patience.
