It was developed by Epicenter Studios and distributed by Conspiracy Entertainment and UFO Interactive Games.

Two players can play what is called a "competitive co-op" throughout the game.

Players will take on the role of the main character (voiced by Neil Patrick Harris) who has the ability to defeat enemies (often zombies) with the power of rock as he searches for his love interest (voiced by Felicia Day).

Players have a few weapons at their disposal (including a shield and blast power-up), but the player can only use these by strumming the correct colored fret buttons in order on their guitar controller.

The developers have bands record rock versions of classical music.
