The Penny Arcade Expo, better known as PAX, has been doing its thing in various cities for ten years now. If you haven't heard of it, it's basically a tiny microcosm of video game trade shows put on with the intention of welcoming actual gamers and fans instead of press or investors. The Expo is put on by the creators of the long-running Penny Arcade web comic and their team, hence the name. To celebrate the 10th PAX Prime, the ceaseless folks at Humble Bundle have created yet another collection of pay-what-you-want games for charity.

This one includes both mobile and desktop games: three of them can be played on Android, while all of them can be redeemed on Steam or as a separate download for the PC. Android gamers can enjoy the beautiful atmospheric platformer Badland, frequent Humble Bundle participant Solar 2, and the odd undead tile-swapping game Containment: The Zombie Puzzler. The Android portion of the bundle is worth $9 by itself, but the bundle also includes the Steam/PC games Jamestown: Legend of the Lost Colony, and for those who pay more than the average (currently just below $4), The Swapper and FEZ. Paying more than $15 gets you the PC games Cannon Brawl and Life Goes On.

As always with the Humble Bundle, you can split your payment between supporting the indie developers, a selected charity (in this case Child's Play), or a tip to the Humble organizers. Since this is a "flash" bundle it's going on for less time than usual, and it will end on Tuesday, September 2nd. PAX Prime is being held in Seattle starting today. Don't forget that you can log in to the official Humble Bundle app to download games and other goodies directly to your phone or tablet.
