Dark Void Zero is a 2D action game and a spin-off of the third-person action game Dark Void. It was released in North America on January 18, 2010 and in the PAL region on March 5, 2010. The game was later released on the iPhone and Steam (PC) platforms on April 12 the same year.
Setting it apart from the next-gen version, the game was designed as a retro title featuring 8-bit graphics and sound, with 2-D gameplay in the same vein as the Metroid games.
To promote the game, a fake "history" was created in which the game was said to be a title Capcom was developing to be a breakthrough NES property in the late 80s, but was shelved with 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.
Both the iPhone and PC versions have an all-new secret ending. The Steam version has an additional ending (for a total of three possible endings), Steam Achievements, and online leaderboards.
To go with the retro feel of the game (similar to Mega Man 10), the Yashichi is featured as an item which generates an electric force field around the character Rusty, making him invincible and damaging enemies upon contact for a short period of time.
