The Binding of Isaac designer Edmund McMillen has revealed some early details about the game's upcoming expansion, which has been officially dubbed "The Wrath of the Lamb". Isaac fans can pick up the expansion for $3 later this year.
One lone screenshot reveals a few new additions such as a level made up of wood planks and one of the trinkets that grant extra passive buffs for Isaac. 74 new items will be added with "The Wrath of the Lamb", some of which you might be able to find from fortune teller machines (another new addition).
McMillen also mentions there's a chance Isaac may be converted to Flash 11, which should improve the game's performance.
