DOES Rock band drums work with guitar hero metallica?

Rock Band drums do not work directly with Guitar Hero Metallica, as they are designed to be used specifically with Rock Band games. However, there is a community project called "Clone Hero" which allows players to simulate playing Guitar Hero using keyboard or MIDI devices, including Rock Band drums. This requires unofficial fan-made modifications and customization to the game, so it's not an officially supported feature, and the specific instructions may depend on the version and platform of Clone Hero you are using.
