Catacombs

The Catacombs is one of the environments of Chapter 2.
The Catacombs are unlocked once each boss in the Caves has been defeated. It generally possesses more spiders and decayed enemies/bosses than the caves, like gurgles or guts.
After A Secret Exit is unlocked, a boarded door similar to the one leading to a Bedroom will appear in this floor's Boss Room upon defeating the boss, leading to the Mines / Ashpit. This door, like a Bedroom, requires two bombs to be opened. Unlike Angel Rooms and Devil Rooms, this door never disappears.
