The Bit.Trip games follow the adventures of Commander Video. All of the games feature a chiptune soundtrack. The gameplay is rhythm based but each game has a unique spin on it. Beat involes bouncing projectiles off a paddle, Void involves gathering black dots and dodging white dots, and the runner games involve using abilities to platform through a level. Successfully playing the games adds tones into the soundtrack, while failing will either restart the level or result in missing notes in the music.
Bit.Trip Runner was the only game to have a direct sequel, and the sequel is the only game to not have 8 bit graphics.
