Developed and published by Aspyr, both editions are said to "match their console counterparts with explosive new content and features," right down to the tracklist and online multiplayer.

"Working with such a wildly successful franchise and helping to strengthen an already powerful brand has us feeling like rock stars ourselves, only without the fame, money or musical talent," jested Aspyr executive VP said Ted Staloch. "Aspyr's expertise in developing and publishing for these platforms means that we will deliver a game that wails just as hard as it does on consoles but feels natural on this audience's chosen platform."

"Providing the option for our fans to play Guitar Hero at their desk or on a laptop on the go is incredibly exciting, and we're thrilled to now offer the ability to rock out literally anywhere and everywhere," elaborated RedOctane publishing head Dusty Welch. "PC and Mac gamers can now shred as hard as their console counterparts do, and it's a great opportunity to help promote musicianship and expand the growing number of Guitar Hero fans worldwide."

Shacknews has inquired to Aspyr on a number of subjects, including support for the Xbox 360's USB-connected Guitar Hero controller, the upcoming wireless guitars, downloadable song packs, and the possibility of a custom track creator.
