Not only does Eddie get a regular axe to wield but the guitar he brings with him from the real world is able to summon powerful magic when played. The game's a third person beat 'em-up at heart, but you've also got your own customisable car to drive and armies of followers to command once you get further into the game.
On top of that you get to team up with rock superstars like Ozzy Osbourne and Lemmy from Motorhead, each of which can help out with their own monster-slaying moves. With a hilarious script from the best writer in gaming this game rocks more ways than you count.
