Humble is selling Rockstar Games on the cheap to save the rainforest

$15 gets you a whole lot of 'Grand Theft Auto,' 'Max Payne' and more.

Want a way to pick up a bulk of Rockstar Games' back catalog and help a good cause? Then head over to Humble where donating $1 or more will get you Grand Theft Auto III, GTA: Vice City and the grisly stealth game Manhunt. Bumping up your pledge to $8.13 adds Bully: Scholarship Edition, GTA IV, GTA: San Andreas, L.A. Noire and Max Payne 3 to your haul.

And finally, if you drop $15 or more you'll snag all of the above plus Max Payne Complete, comprised of all three Max Payne games and the third's post-release add-ons. If you need an audio reminder of one of Max Payne 3's best moments, peep the YouTube embed below. The promo runs through February 12th, so if you're looking to score a deal, you should donate sooner rather than later.

However much you pledge it'll go toward supporting The Rainforest Alliance, a conservation group made up of farmers, scientists and more. For the past 30 years, the Alliance has worked to bolster biodiversity and ensure land is sustainably managed.
