Now there's even more reason to use that holiday cash Aunt Myrtle sent you on something charitable. The ongoing Humble Indie Bundle 7 has just expanded its indie game offerings to include The Basement Collection of Flash games, the action puzzle platformer Offspring Fling, and the retro 2D platformer Cave Story. The original bundle was packed with indie hits Snapshot, Closure, The Binding of Isaac and its Wrath of the Lamb DLC, Shank 2, Dungeon Defenders and its DLC, Legend of Grimrock, and the documentary Indie Game: The Movie. So, for the next six days, you can snatch up nine full games and one movie for a price that's absurdly close to free.

If you haven't done a Humble Bundle before, here's how it works: You can donate any amount of money and receive Snapshot, Closure, The Binding of Isaac, Shank 2, and Indie Game: The Movie. But if you pay more than the average ($6.41 as of this writing), you'll also get Dungeon Defenders, Legend of Grimrock, The Basement Collection, Offspring Fling, and Cave Story. The folks at Humble Bundle estimate the total value of this collection at $170. You can even choose how you'd like to have your payment divided between the developers and the two benefiting organizations, Child's Play Charity and the Electronic Frontier Foundation.
