Humble Indie Bundle 4 now live

The fourth Humble Indie Bundle promotion kicked off today, and the latest installment in the twice-a-year, pay-what-you-want promotion is boasting some pretty high-profile offerings.

Five games are included in the Humble Indie Bundle 4 base package, including Super Meat Boy, Bit.Trip Runner, Shank, Jamestown, and Nightsky HD. For those who pay more than the average amount (currently at roughly $5), Cave Story+ and Gratuitous Space Battles are also included.

As with previous Humble Bundles, any amount over a dollar is accepted, and the payment can be split at will between developers, charities, and the package organizer, Humble Bundle Inc. The money for charity goes to Child's Play and/or the American Red Cross, with customers able to split the proceeds between parties to their liking.

All games in The Humble Indie Bundle 4 are compatible with Windows, Mac, and Linux. The games are DRM-free and can be redeemed through Steam.

As of press time, more than 100,000 bundles have been sold, with a total of more than $500,000 raised. The original Humble Indie Bundle launched in May 2010 and raised $1.27 million, and the following two raised $1.8 million and $2.16 million respectively. The Humble Indie Bundle 4 will be available through December 27.
