On April 9, 2004, Konami announced a DVD called "OPTIONS" was being offered to pre-ordering customers in Japan — containing interviews with the developers, art galleries and a number of videos demonstrating the inner workings of the game's levels. Adding further incentive for customers to purchase the upcoming game, Konami later revealed the availability of "The History of Vic Viper —" a book indicating inner design, the background and the roadmap of the Vic Viper ships. The book was included with all versions of the original Japanese pressing of the game. An additional DVD with expanded content titled "Gradius V Official DVD The Perfect" was also released in Japan to be ordered separately or with the game from Konami's online retail store, Konamistyle. For the North American release of the game, Konami produced a DVD called "Gradius Breakdown" as a pre-order incentive. "Breakdown" includes a retrospective of the "Gradius" series and a number of recorded playthroughs of the game.
