IGN reports that an official PC and Mac version of Activision and Red Octane's Guitar Hero III: Legends of Rock (Xbox 360, PlayStation 3, Wii) is currently being readied by Aspyr Media for release this fall.

The PC and Mac version of the latest installment in the popular rhythm game series is being developed and published exclusively by Aspyr Media. Gamers can expect the same gameplay and content found in the game's console versions.

Guitar Hero III: Legends of Rock for the PC and Mac will come with more than 70 songs, unlockable content and a head-to-head multiplayer mode. The game will also include an online multiplayer mode so gamers can battle it out riff for riff against other PC and Mac gamers.

System requirements as well as peripheral support details have yet to be revealed. The X-plorer guitar controller for Guitar Hero II's Xbox 360 version is already Windows XP and Vista compatible, though, so those who have that game probably won't have to buy another controller. Stay tuned for more news.
