Amp up your Android device and donate to a good cause while you’re at it with the new “Humble Bundle for Android” collection released this week!

This “pay-what-you-want” bundle allows you to name your price for four new games while helping raise funds for the Child’s Play charity, an organization to benefit children in hospitals through the support of the gaming community.

The bundle includes the reverse tower defense masterpiece Anomaly: Warzone Earth HD, Osmos HD, a soothing, visual symphony of hungry amoebas, the cube-rolling puzzler EDGE, and customers who contribute more than the average price will also receive World of Goo, the indie physics smash hit. Check out the video below for a sample of what the package has to offer. (The celebrity impersonations alone are worth the watch.)

All of these games are also available in Windows, Mac, and Linux versions. The Humble Bundle also includes the soundtracks to the games, and are available for purchase now at http://www.humblebundle.com.

Purchasers can select from four pre-set increments ranging from $15 to $165, or choose a Custom amount and enter a donation of his or her choice. The contribution can then be divvied up among three recipients that include the games’ developers, the Child’s Play charity, and a “Humble tip” that supports Humble Bundle Inc.’s development of their promotion.

Bought separately, these games would cost more than $60, so be sure to take advantage of this “pay what you want” deal and give to a good cause before the offer expires in 12 days!
