Spin-off
A spin-off title for DSiWare called Dark Void Zero was released in North America on January 18, 2010 and in the PAL region on March 5, 2010. Setting it apart from the next-gen version, the game was designed as a retro title featuring 8-bit graphics and sound, with 2D gameplay in the same vein as the Metroid games.
To promote the game, a history of the game was created in which it was a title Capcom was developing to be a breakthrough NES property in the late 80s, but was shelved with the discontinuation of the PlayChoice-10 and the coming of the SNES. This history also appears in-game during the introduction. Additionally, before starting the game, players must use the DSi microphone to blow the cartridge's "contacts", a homage to the age-old method of getting non-working NES games to play.
Capcom manager Seth Killian said Dark Void Zero started development after finishing the pre-release copy of 'Dark Void, which has 8-bit music playing over the ending credits.
Dark Void Zero was also released on the iPhone and Windows platforms on April 12, 2010. Both versions have an all-new secret ending. The Steam version has an additional ending (for a total of three possible endings), Steam Achievements, online leaderboards, and a SecuROM 5 machine activation limit.
