Supposing you missed the action/adventure title fused with heavy metal and the most metal of voices - Jack Black - the folks at Humble Bundle and Double Fine are bringing on some alleviation to your pain. They've created a Humble Bundle Weekly Sale that, per usual, donates cash you're willing to deliver for both fine video games and some choice charities.
This particular bundle is working with Double Fine games that include DRM-Free versions of the titles Psychonauts, Costume Quest, and Stacking. Users willing to go the extra bit, dropping a six-dollar sum or more, will also gain access to Brutal Legend. This game was originally released several years ago, but its just as fresh as ever with a comedic take on the metal universe of games.
There's also an Early Access game being made available through this particular ushering in of Humbleness called Spacebase DF-9 which you'll be having a peek at here. With Early Access, you'll be asked to be OK with the occasional break in the game here and there in exchange for the ability to play the game before it's made generally available.
Each of these games will be available through Steam or as their own DRM-Free files once the portal is crossed, and they're all available for Windows, Mac, and Linux as well. Each title is DRM-Free save the Spacebase DF-9 title due to its Early Access nature. You'll also find music albums for Brutal Legend, Costume Quest, and Stacking, as well as both a Soundtrack and Score from Psychonauts included.
