With Cathedral-styled walls, Cathedral is the polar opposite of Sheol and is the other option of floor to go after defeating It Lives. Identical in appearance to The Womb, Utero is identified by different enemies, such as Mask + Hearts and Angelic Babies, and different boss types. It generally features harder versions of enemies from The Depths. Necropolis is an alternative form of The Depths. The Catacombs contain tougher enemies than the Caves, such as Keepers and B.
The Catacombs replaces The Caves in a similar fashion to how The Cellar can replace The Basement. The Cellar's enemies/bosses are arguably harder than that of the Basement's, making it a challenge for newer players. Areas of webbing appear in the terrain which slow Isaac's movement and the speed of tears that pass through. The enemies differ from those appearing in the Basement, featuring an increase in the number of Spider-themed Enemies. The Cellar is an alternative version of The Basement which can randomly replace one or both Basement levels in a playthrough.
