It was just one week ago that the last Humble Indie Bundle ended, but the people behind HIB have been pushing out lots of bundles as of late with mixed success.
The titles of Humble Indie Bundle #4 include Jamestown, Bit.Trip Runner, Super Meat Boy, Shank, and NightSky HD. If paying more than the floating average (currently at $4.53 USD), you also get Gratuitous Space Battles and Cave Story+. I've never heard of any of these titles previously, so below is the trailer of Humble Indie Bundle #4 should you be interested.
You can still donate a portion of your game price to charity, but this time the Humble Indie Bundle developers have replaced the Electronic Frontier Foundation with the American Red Cross.
In the short time the bundle has been live so far it's already raked in $115k USD from more than 25,000 sales.
