Activision has popped a Guitar Hero: Metallica demo on Xbox Live Marketplace.
The sampler is just over 1GB in size, and offers songs "Sad But True" and "Seek And Destroy" by the titular band. "No Excuses" by Alice In Chains and "Stone Cold Crazy" by Queen also feature.
All four tracks can be replicated on guitar, drums and microphone, and in either single-player, band quickplay, head-to-head, face-off, pro face-off and battle modes.
The full Guitar Hero: Metallica game features over 45 tracks by the band, plus input from 21 other rock stars and groups, including System of a Down and Foo Fighters.
Guitar Hero: Metallica will be out on Xbox 360, PS3, PS2 and Wii this May.
