The Humble Bundle has debuted their 4th charity bundle for the American Red Cross and Child’s Play, giving gamers an opportunity to pay what they want for a handful of indie games that are DRM-free while donating to two great causes. This holiday’s Humble Indie Bundle includes Super Meat Boy, Cave Story +, Bit.Trip Runner, Gratuitous Space Battles, Shank, NightSky HD, and Jamestown if you pay more than the average amount donated. Donations for the Red Cross, Child’s Play, the game developers, and the Humble Bundle folks themselves can be adjusted before checkout. All gamers are given access to a special key where they can download the games on any platform of their choice, whether it be Windows, Mac, or Linux. If you’d like to gift the Humble Bundle to a relative or a friend as a holiday gift, simply check that option before checking out with PayPal, Amazon Payments, or Google Checkout.
