Bit.Trip, stylized BIT.TRIP, is a series of seven video games developed by Gaijin Games and published by Aksys Games for the Wii, Nintendo 3DS, and the PC. It was published by Arc System Works for WiiWare in Japan, and by Namco Networks America Inc for the iPhone, iPod Touch and iPad. Each game revolves around the adventures of a character named "Commander Video", and features "a crazy mix of 80s aesthetics and modern game design". The styles of the games range from pong remakes, platforming, and shooting. Each game in the series features a chiptune-inspired soundtrack, but a different style of rhythm-based gameplay in each. Beat, Core and Void each contain three distinct levels, each one ending in a unique boss battle. Most bosses are based on various games and game genres from the early Atari era, as are the various bonus stages.
