The Dark Room is one of the game's three final stages, alongside its counterpart, The Chest, as well as The Void. The Dark Room is unlocked by defeating Satan 5 times, after which it can be accessed by touching the chest dropped by Satan with The Negative equipped. Entrance to the Dark Room can also be achieved via the I AM ERROR room on Sheol, even without The Negative as well as through the Black Market room on Sheol. After completing this level or the Chest for the first time, the Dark Room will always contain a large golden door in the first room, which can be unlocked with both Key Piece 1 and Key Piece 2 or Dad's Key, allowing access to Mega Satan.
The Dark Room can also be accessed by repeatedly using a Sacrifice Room. After Uriel and Gabriel are killed, continuing to use the Sacrifice Room will teleport Isaac to the Dark Room, regardless of what floor he was previously on.
The Dark Room also contains dirt mounds, which can be dug up using Mom's Shovel. Doing so for the first time will unlock The Forgotten. On subsequent runs, multiple dirt mounds can be found, and digging them up using We Need to Go Deeper!, an Ehwaz rune, or Mom's Shovel will spawn a random type of chest.
Like Sheol before it, the Dark Room consists of only one floor. In the Dark Room, it is not possible to bomb doors open to skip rooms. The Dark Room's rooms are mainly filled with bosses and mini-bosses. The boss of the floor is always The Lamb.
The first room you spawn in will automatically contain 4 Red Chests. Red Chests will also drop frequently upon clearing a room, regardless of whether the player has the Left Hand trinket or not. Additionally, all brown and golden chests spawned in the Dark Room will always contain Treasure Room items.

Notes[edit | edit source]
- If Isaac gets Key Piece 1 and Key Piece 2, the key will open the golden gate to fight Mega Satan, but if Isaac uses Forget Me Now, the floor will reset and Isaac won't get both Key Pieces back, making it so that the golden gate won't open again.
- The I AM ERROR room cannot be reached by any method in The Chest and the Dark Room.
Unlockable Achievements[edit | edit source]
Music[edit | edit source]
The music for the Dark Room is titled Devoid, which means “empty”.
Trivia[edit | edit source]
- The Dark Room is also the name of a room which, like its name suggests, is plunged into complete darkness, for the notable purpose of processing photos. The fact access to this floor is done by touching the chest in Sheol while holding The Negative, which is the name given to a photo which has not been processed yet and whose colours and hues are inverted, might be a nod to this.
- The layout to the Chest and to the Dark Room are identical for a given seed.
- One of the Super Secret Room layouts is of the Dark Room and a Black Heart. The sprite for the door is a portal rather than a gray door, however, due to the fact that bombed-out entrances in the Dark Room appear as portals.
- This secret room appears floating in a black void on most floors, but in the Dark Room it appears in a purple misty void instead, just like all the other rooms.
