If you haven't checked out Team Meat's The Binding of Isaac yet, you really should. The Super Meat Boy developer's second game is as twisted as they come, and throws back to the old-school of gaming where checkpoints and save anywhere options weren't even part of the design document.

Today the indie team has announced a release date for an expansion to Isaac, called Wrath of the Lamb, that will only set you back US$3 on Steam and comes packed with new content - all of which will be as creepy as the original game itself, and likely then some. It'll be available to pick up on May 28.

You can grab The Binding of Isaac now on Steam for a $5, which is pretty much a bargain for the amount of content you get, and seriously, if you still haven't played Super Meat Boy, we can no longer be friends.
