Necropolis is the alternative chapter of the Depths. It is a dark environment infested with insects.
Necropolis is unlocked by defeating every boss from The Depths at least once.
The boss of Necropolis II is always Mom.
After A Secret Exit is unlocked, a door will appear in Necropolis I's Boss Room upon defeating the boss, leading to the Mausoleum / Gehenna. This door requires two hearts to be opened (except on Lost characters). Unlike Angel Rooms and Devil Rooms, this door never disappears. After defeating Mother for the first time, a Strange Door will appear in the starting room of Necropolis II. This door leads to Mausoleum / Gehenna II before entering the Ascent.
