lists for $19.99 on the steam store
Brütal Legend is an action-adventure that marries visceral action combat with open-world freedom. Set in a universe somewhere between Lord of the Rings and Spinal Tap, it’s a fresh take on the action/driving genre, which in this case is full of imitation cover bands, demons intent on enslaving humanity and Heavy metal tunes.
I will send you the key to redeem via Steam through Listia's contact link after the auction is over. You do have to have Steam installed to use this key for this game.
