Into The Abyss is the third chapter of Slender: The Arrival.
Following the events of The Eight Pages, Lauren wakes up the next morning in a field. After exploring the area, she comes across a tunnel leading to the abandoned Kullman Mines. Inside, she finds a note saying, in order to escape, she must first activate six generators to power up an elevator. Lauren finds the first generator next to the elevator. After activating the second generator, she realizes she is being chased by a feral creature wearing a white hoodie and mask. Simultaneously trying to avoid both Slender Man and the hooded creature, she manages to activate all six generators and exits the mines via elevator.
- On Hardcore difficulty, the player must collect gas canisters before powering the generators.
- When the player falls from the elevator, the game still displays the normal game over screen (the Slender Man death screen) despite that they are not caught by him. This situation maybe happens because any form of death in this game will still end the game or if they touch the button to start the elevator, it will go up and the proximity between the level of the elevator and the ground is higher.
- However, when they fall out of the map at the same time falls from the elevator, the same situation will happen but with the message "Not even a bug in this game will save you from me."
