Most of Antibirth's features have been integrated officially into the Binding of Isaac: Rebirth as its 3rd DLC, The Binding of Isaac: Repentance, but the fanmade expansion will continue to be available for free! The mod includes new items, characters, enemies, challenges, secrets, and much more! The mod was primarily developed by Kilburn, NotYourSagittarius, and LeatherIceCream, with music by Mudeth.
