If you like Guitar Hero and Metallica, this is for you! The Metallica songs that are on this are all awesome, ranging from there early days to there earliest stuff. There are also a lot of other artists on GH: Metallica like Mercyful Fate, Queen, Foo Fighters, Slayer and Machine Head to name but a few. The career mode is short and sweet but if you're playing it on co-op with someone at home, only the "Band Leader" will unlock the 100 stars in career achievement AND the achievement to complete career on co-op. But it's not as if you wouldn't mind doing career mode over and over in this game. I would say that this is the best Music Rhythm game out there. I'll just add that I'm surprised that Harmonix hasn't made a Rockband Megadeth lol. But as I said before, this IS the best music rhythm game out there and I highly recommend it if you like Guitar Hero games or if you're a fan of Metallica.
