Diehard GameFAN writes: "While Guitar Hero: Metallica might seem like a pricey song expansion pack, players get a full-fleged experience with mode offerings comparable to Guitar Hero: World Tour. Neversoft took Metallica's involvement seriously with incredible graphics and animation and, of course, the title represents each artists' music offerings well. The game play hasn't advanced one bit since World Tour, but given the franchise's pedigree, fans of the series won't be looking for a drastically different experience. While the number of songs on-disc is a handful lower than World Tour, everything players love about Guitar Hero is here with a fresh coat of paint. Metallica's involvement gives plastic guitar players a lot of notes to shred and the double bass action on the drums will challenge even the most seasoned of drummers. Fans of music games shouldn't pass this one up unless they just really can't stand Metallica".
