Rhythm game built on Guitar Hero World Tour's engine, centered entirely on Metallica's catalog. You play through 28 master recordings from the band's discography plus 21 guest tracks they picked themselves, using plastic guitars, drums, and a mic. Supports full four-player band mode with lead/bass guitar, vocals, and drums. The drum chart adds an "Expert+" tier requiring a double bass pedal to replicate Lars Ulrich's kick patterns—a first for the series at the time. Career mode runs through both solo and band progression paths, while online modes let you compete or jam with others. Includes motion-captured performances of the band, behind-the-scenes footage, and Pop-Up Video-style trivia during songs. If you want Metallica specifically or crave harder drum charts than World Tour offered, this delivers. Casual players won't feel locked out—the difficulty spread works better than Guitar Hero III's spike.
