Extra Contents is a recurring feature in the Dept. Heaven series.
Extra Content can be accessed on the title screen of Riviera: The Promised Land. It is available from the get-go, but the extras within it must be collected by playing the game. Fully completing everything in the Extra Contents menu will require multiple playthroughs.
