This Humble Bundle weekly is live! Pay whatever you want and you'll get Shank 2, Blocks That Matter, and Bit.Trip Runner. Notice the pattern? Platformers!
Pay over $6 and you'll also get Bit.Trip Presents Runner 2: Future Legend of Rhythm Alien, Megabyte Punch, and Fly'n. Pay over $10 and you'll get King Arthur's Gold, and Mark of the Ninja: Special Edition. Plenty good offerings in this collection, but $10 alone is worth it just for Mark of the Ninja.
Oh, and some soundtracks are part of this bundle for a few of the games. The charity portions will also go to American Red Cross and Child's Play should you choose those options.
