Types of Doors
There Are Two Types of Doors
- Flesh Door
- Doors
The Doors inside the Hell Gate are broadly divided into two types: Flesh Doors, which require a key to open, and regular Doors.
Flesh Doors Hide Valuable Items

Flesh Doors come in five types: Eye, Ear, Mouth, Whirlpool, and Shadow. They can only be opened when you have the matching key in your Backpack. In most cases, a Treasure Bud containing a valuable item is hidden behind them.
Doors Are Controlled by Raiders

Doors can only be moved by a Raider. Interact with them to open or close the Door.
How to Use Doors
Use Door Status to Track Raiders

Doors are closed by default. If you find a Door already open, assume another Raider has passed through. You can also take advantage of this by closing Doors behind you to conceal your movements and potentially mislead other Raiders.
Close Doors to Avoid Enemy Encounters
Some Yuckies can open Doors, while others cannot. Closing a Door does not guarantee avoiding combat, but it can help you dodge certain enemies.
Yuckies That Can Open Doors
If you are spotted by a Humanoid or Yotsuyama, they will open the Door and continue chasing you even if you close it.
Yuckies That Cannot Open Doors
Yuckies other than Humanoids and Yotsuyamas appear unable to open closed Doors. We are currently investigating whether any other Yuckies are an exception.
