Flooded Caves.png

The Flooded Caves is one of the environments in Chapter 2 added in the Binding of Isaac: Afterbirth expansion. The theme of the Flooded Caves is water; as such, most of the enemies inhabiting it are airborne, such as One Tooth and flies, and many of them shoot projectiles, while there are fewer ground-bound and contact-damage-reliant enemies. Rocks have a chance to be replaced with water-filled pits and some enemies like the Hive have a chance to be replaced with their drowned variants.

The Flooded Cave's alternate floors are The Caves and The Catacombs.

The Flooded Caves are unlocked by defeating It Lives 16 times.
