If you've never played Guitar Hero, you've been missing out. It's quite an experience - you play with a special guitar controller, and as notes fly towards you on the screen, you hit both fret buttons and a strum bar in time to real life rock music. I'm a huge fan of the series, having played the original on PS2, and Guitar Hero II on my Xbox 360. Now, Mac owners will can to take the stage: Aspyr Media has announced that they're bringing the series' third iteration to the Mac.
Guitar Hero III is scheduled to be released in October on the consoles and PC. Aspyr will release a hybrid Windows/Mac box, complete with USB guitar. System requirements haven't been released yet, but I'd expect any PC version to have everything the console versions do. The complete setlist contains pretty much any kind of rock you're interested in, from Rage to Bloc Party to Kiss, and even the D and gamer favorite DragonForce.
Sounds awesome. Considering the guitar is just a USB device, how cool would it be to integrate it with Garageband? Here's hoping Aspyr stays on beat, and makes the PC/Mac version available shortly after the console release. Until then, you may always rock it out with Frets on Fire. Throw the horns!
