Brütal Legend, Double Fine’s metal/fantasy extravaganza, starring Jack Black and a guitar that truly shreds (his enemies), is free for a limited time through the Humble Store.
At the time of this writing, you have roughly 1 Day 19 hours to reap the benefits of this offer.
For the uninitiated, Brütal Legend originally hit consoles back in 2009, but it took it until 2013 to come to the personal computer. It mixes open world action and strategy to a pretty interesting degree.
Head on over to the Humble Store to grab yourself a copy.
