Expanded Rooms: A-100 (The Creep) Encounter
Not to be confused with A-100 (Interminable Rooms), G-55, and CG-55.
A-100 will warn you by making your screen sightly black and emitting a horror sound. You have some time to hide in a hiding spot (wardrobes, tables) before it reaches the latest room. It will check all lockers and all blue lockers. After it's finished doing that, it will go back to A-000. It will repeat it's process 1-4 times. Once it's finished repeating it's process, it will charge to the unopened door, and then it will despawn.
This entity will have a J variant.
Expanded Rooms will release soon or some day.
