Added in Repentance

The Corpse is a new floor added in The Binding of Isaac: Repentance, which acts as Womb Womb's alternative Chapter. It features a desolate and dreary atmosphere with enemies that carry the theme of death and advanced rot. The Corpse is one of five final levels in The Binding of Isaac, alongside Chest Chest, the Dark Room Dark Room, The Void The Void and Home Home.

To access The Corpse, the player must first open the flesh door at the end of the Mausoleum Mausoleum/Gehenna Gehenna II after defeating the Mausoleum version of Mom by doing one of the following:

(Note: The item Mama Mega! Mama Mega! can not be used to open the Flesh Door)

On the other side of the flesh door, the player will fight the Mausoleum version of Mom's Heart, after which the entrance to the Womb will turn into the Corpse entrance, which will take the player into the Corpse floor.

The boss of Corpse II is always Mother.

The Red Key Red Key cannot open doors to the I AM ERROR room in Corpse II.
We Need to Go Deeper! We Need to Go Deeper! and Rune of Ehwaz Rune of Ehwaz cannot generate trapdoors in Corpse II.
An I AM ERROR room can only be visited in Corpse II via clipping out of a Crawl Space; such I AM ERROR room will contain either a passageway which leads back to the starting room of the floor or an entrance to ???.

    • An unused floor named Mortis presumably as an alternative to Corpse exists in the game files.
  • In Antibirth, The hole to the Mother battle had 4 Golden Chests next to it that always contained items, similar to chests in The Chest.
  • If a room's floor is filled with blood, there will be a huge blood stain on the floor upon entering any room adjacent to it.
