Brütal Legend is AWESOME! The landscape is perfect, the tunes are awesome. The Battles are just right!
The story is great, though a bit typical, but the main plot is this: Eddie Riggs is a Roadie for a 2000 Heavy metal band, and he hates the 2000 and he wishes that he could go back in time, a stage accident makes Örmagodden the Fire Beast take him back in time. Here he joins forces with Lars Halford in bringing down LionWhyte and Emperor Deviculous. During this quest he makes new (familiar) friends, like Lemmy Kilmister and Ozzy Osbourn. You travel through roughly 6-7 different landscapes in your quest starting on the plains and ending up in a cave with a lake of black tears.
Around the big open world, you may find Legends, which will tell you the background story of the awesome land you have arrived in.
There is also a multiplayer option in Brütal Legend, which runs through the PSN and is a highly recommended feature to use after playing the single player campaign. The campaign is quite short yes, but there are multiple ways to entertain yourself besides that.
The music choice in BL is great! there are of course some other Bands you might want to include, I, for one, would have loved to see some Iron Maiden since they actually take part of the story in a more hidden way. But yes, Black Sabbath, Judas Priest, Mötorhead and many many more bands have songs included in this masterpiece of a game.
