Brutal Legend was an incredibly-fun RTS/third-person action-adventure game when it was first released about a decade ago. It provided a slew of rock music-focused action with a killer soundtrack. Today, the Humble Store began giving the game away via a Steam key for 48 hours. It normally goes for $14.99 — so getting it for free is quite a deal even if it has been in bundles before.
If you’ve missed out on it, but love either RTS, action-centric brawlers or Jack Black, give it a shot. His voice acting is outstanding and he really brings a sense of life to Eddie that isn’t in most protagonists.
