The makers of Braid, Cortex Command, Machinarium, Osmos and Revenge of the Titans have teamed up with the Electronic Frontier Foundation and Child's Play to offer the Humble Indie Bundle #2.
Child's Play donates toys, games, books and cash to children in hospitals around the world. The Electronic Frontier Foundation (EFF) is an international non-profit digital rights advocacy and legal organization.
Here's how the Humble Indie Bundle #2 works:
1. Go to http://www.humblebundle.com
2. You choose how much you're willing to spend on the bundle of these five excellent indie games. You can choose any amount from $0.01 (cheapskate) to $1,000,000,000 (why hello, Mr. Gates!)
3. Use the sliders to determine who gets what percent of the money from step 2: All to the developers, all to the EFF, all to Child's Play, all to Humble Bundle, Inc. as a tip for running the promotion, an even split across all of them, or you can set the percentages manually.
4.Play the games firm in the belief that you've helped a good cause!
All the games come in versions for Windows, Mac OS X, and Linux and are DRM free.
