Overview

A-600 spawns at rooms A-600 and above. It is quite sensitive to movement, but has bad eyesight, meaning any movement while within range of the active entity will lead to death.

Appearance

A-600 has the appearance of a face which has red eyes that are bleeding, along with a bloody mouth and a nose. It also emits a bright red color when spawning in-game.

In A-600's jumpscare, its eyes and mouth are completely black with a bulge effect.

Behavior

Upon opening door A-600 and above, A-600 will spawn in the middle of the current room. A-600 only lasts for a few seconds. If the player makes the choice to move, it will move to the player at an extreme speeds and kill said player.

Survival Tips

A-600 can be compared from A-90 from DOORS due to their similar mechanic, so it is best to use that to your advantage when encountering A-600.

If another entity spawned with A-600 the player can either choose to wait for A-600 to despawn, or quickly go to the nearest locker and hide in it.

Before entering a room, open the door and stay still for a few seconds so you become safe from A-600.
A-600 will only grant the player(s) 3 seconds to stay still.

Trivia

A-600'sjumpscare is inspired by a game called Sara is Missing. It uses the red room sequence (loud sounds and blood warning) as an inspiration for a "jumpscare" where A-600 is trying to tell the player an event or story by scribble-like drawings on a red background, which makes it hard to understand what A-600 is actually trying to tell to us.
A-600's origin image comes from Ahenobarbus Henocied. If you want to know more about its origin, go here.
If you move accidentally while A-600 has spawned, there is a small chance you can survive.
A-600 used to make the player stand still for 8.3 seconds, but it got decreased to 3 seconds due to hard combos such as A-500.
A-600's jumpscare shows a few things, one being a house. After A-600's scribbled drawings stop, it morphs into its jumpscare form and glitches the screen like crazy, then killing the player.
A-600 is the first entity to have a nose, the second being A-1100.
A-600's Image may not load on certain devices, for example mobile devices like cell phones
In the current jumpscare the scribbled drawings flash from red to white constantly
A-600 can be hard to differentiate of A-1100 due to their particles and color being very similar

Lore:

English: A-600 is a creepy entity originating from the depths of a Japanese prison

Over time it was being built on the collective insanity of the prisoners.
