A Door eerie is a type of map that is made of trap doors. The trap doors create a tunnel and the trap doors themselves work as walls. The path will lead to the door, yet if there are two paths, one can be a wrong path and the other one can be a right path, that's why trap doors are useful for in this level. Some door eeries contain locked doors that can be useful. Professional door eerie creators can make cool effects and loopholes with locked doors.
