Humble Bundle offers downloads of the Humble Indie Bundle #4 for Windows or Mac for whatever you want to pay. If you opt to pay the bare minimum of one cent, that's the lowest price we could find for this 5-game bundle by $50. It includes Jamestown, Bit.Trip Runner, Super Meat Boy, Shank, and NightSky HD. Your contribution can be donated to charity (Child's Play or the American Red Cross), the developers, or both.

If you opt to pay more than the average (currently $4.61) you'll get two bonus games — Cave Story+ and Gratuitous Space Battles.
