Mausoleum

A hatch, leading to Mauseleum

Mausoleum is a new environment added in Antibirth. It contains many teleporters that can connect different parts of the same room or two different rooms.

The Mausoleum is always segmented into two main areas. The primary area, where Isaac enters, contains a standard set of rooms along with a special teleporter room. The teleporter room requires Isaac to expend resources or maneuver through obstacles to reach a teleporter, which transports Isaac to the secondary area. The secondary area contains a few rewards, along with another random special room.

Treasure rooms in the Mausoleum always have two items to choose from.

After "A Secret Exit" is unlocked, a locked door to the Mausoleum will appear upon completing The Depths, Necropolis, or Mines. The locked door requires two soul or black hearts to enter.
