Description
The Binding of Isaac is a dungeon shooter where every run lays out different floors, and Isaac clears each room by shooting tears at the monsters inside. Find treasure rooms, shops and secret rooms, and pick up some of the 180 items that change how he fights.
Beat Mom and her heart, then head down to Sheol or up to the Cathedral. Winning a run unlocks ???, Eve, Samson and Azazel.
