Bit.Trip Void, marketed as BIT.TRIP VOID, is an arcade-style bullet hell rhythm game developed by Gaijin Games and published by Aksys Games for the Wii's WiiWare download service. It was first released in Japan in 2009, and later in North America and PAL regions in 2009 and 2010, respectively. It was designed by Alex Neuse and Chris Osborn, while the visuals were designed by Mike Roush. While initially having what they now describe as "noisy" audio and visuals, they changed them to be more minimalistic to alleviate this, a decision which worked well with their minimalistic design for the HUD. Neuse designed it so that it could be open to interpretation by players, though stating that they intended it to delve into starring character Commander Video's psyche, and "what it means to have emotions and personal space."
