„Strange drawings and notes started to appear around the forest. Some folks tried to collect them.... and were never seen again.“ [Unsigned note]

Special State: Looming

The Slenderman can switch between 2 modes: Looming and Pursuit. Switching between these states can only be done while not in a direct line of sight of a survivor and has a 10 second cooldown.
While in the Pursuit state, you function as a regular killer.
While in Looming state, your movement speed is increased to 6,0 m/s, you become invisible and Undetectable. You cannot interact with the enviroment or survivors unless using Jumpscare.

Special Attack: Jumpscare

When in the Looming state, you can preform a Jumpscare by holding down the M2 button. This causes you to become visible and freeze in place. If you do this in a LOS of a survivor, their camera swings towards you and Frightened start building up.
Once a survivor is fully Frightened, you can preform an attack towards them which will teleport you right in front of the survivor, switches their camera to 1st person (similar to Sadako's lobby jumpscare) and take away one Health State from them.

Special Effect: Frightened

This effect triggers passively when a survivor looks at The Slenderman, and decays slowly while they are looking away. If a survivor spots you while preforming a Jumpscare, the speed at which it accumulates is greatly increased.
It causes the survivor to start seeing everything except the Slenderman in a hazy, static-like way, as well as showing their direction to you. The more of it is accumulated, the harder it is for the survivor to flick their camera away from you.

Special Mechanic: The Eight Pages

When The Slenderman is the killer in the trial, only 6 generators spawn, with the objective being to repair 4 of them. The fifth one is replaced by The Eight Pages, which are hung up randomly around the trial. Survivors will become aware of this only when they spot you for the first time.
When coming near one, the survivors have to remove it in a short interaction.
Every time a page is collected, the map becomes foggier, the lullaby becomes louder and more disorienting, the speed at which Frightened accumulates increases, and your Terror Radius shrinks. All of these effects are reverted once all Pages are collected.
You can see the auras of the Pages at all times, and you will be warned with an audio cue and Killer Instinct every time one is collected.
