The latest bundle offering from Humble Bundle, Humble Indie Bundle X, is now available. The bundle offers four indie titles for whatever you want, and two additional games if you pay more than the average price.
Pay whatever you want and get several decent games including To the Moon, Joe Danger 2: The Movie, Papo & Yo, and Runner2. Pay more than the current average of $6.68 to unlock Reus, and Surgeon Simulator 2013. The Mac and Linux versions of Reus are in beta still, but you can play them.
Charities being supported by this bundle are the Electronic Frontier Foundation and Child's Play.
