The Fall Sale on The Humble Store rolls on, and they are now offering a new free game after last week's Killer is Dead giveaway. Today's offering is Brütal Legend, Double Fine's rock-and-roll adventure where you play as a jacked Jack Black. This is playable on Windows, Linux, and macOS, and is redeemed via a Steam key if you pick up your free copy by Wednesday afternoon. Here's a refresher on the game:

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. Featuring the talents of comedian, actor and musician, Jack Black as super roadie Eddie Riggs, as well as cameos by some of the biggest names in metal music it's a wild ride in the belly of the beast that is not to be missed by gamers and Metalheads alike.

Included as a free bonus in the PC version of Brütal Legend are both the Hammer of Infinite Fate and Tears of the Hextadon multiplayer map packs.
