To commemorate the 20th anniversary of the popular Contra franchise of video games, Konami Digital Entertainment plans to incorporate a wealth of in-game bonus content into its latest entry in the run and gun action franchise, Contra 4 for the Nintendo DS™. The content includes:
• 20th Anniversary Virtual Museum – this museum provides a virtual history of the Contra franchise since the early 80’s, including box art, screen shots and information on every version of Contra from the US, Japan and Europe. The museum also features an unlockable gallery of bonus art.
• Unlockable Games – The NES versions of the classic Contra and Super C are now unlockable.
• 5 unlockable characters, including the Probotector from the European version of the Contra games
• 2 unlockable digital comic books from longtime Contra artist, Atsushi Tsujimoto
• An interview with noted Contra Producer Nobuya Nakazato
Set after the events of Contra III: Alien Wars, Contra 4 follows hardened mercs Bill Rizer and Lance Bean into battle against a new extraterrestrial threat, complete with larger-than-life-action, massive enemies, fast paced run ‘n’ gun combat and mind blowing set pieces. The unique dual screen presentation of the Nintendo DS™ allows for frantic action and mammoth boss encounters, and a grappling hook allows players to access hard to reach areas, or dodge that pesky attack from a foe.

Contra 4 features a variety of game modes, including 40 Challenge Modes that will test the limits of even the best Contra veterans, as well as full cooperative play through the main story mode, where two players can take up the fight for mankind and destroy the evil forces of the Black Viper.
