About This Game
a young boy took his first trip down into the basement, facing the endless threats below to escape from the murderous delusions of his loving mother. Three years later, he found himself facing the same predicament but with an even greater plague of horrors and peril. Very shortly afterward, a modest few among us decided that even this was not enough. In the two years since then, fate has worked tirelessly to place by far the most fearsome challenge yet in his path. This time, Isaac will face our free and fan-made The Binding of Isaac: Rebirth expansion, Antibirth. So what exactly is in store for him?
