The Lost Floors is the second main floor of the game of the same name. It is accessed by using one of the trains or creating an elevator via the Modifiers button in the Lost Floors section of the Lobby.
Overview
The Lost Floors are a complex of many sections separated by elevators. Elevators lets you choose between up or down, with the name of the next section(s) on the right when you enter the elevator room. Sections usually have a boss entity inside them.
Sections included are:
- The Basement, a place similar to the underground offices in The Lost Mines. The boss of this section is Figure.
- The Attic, where the Ribseer boss fight and the Seek chase takes place.
- The Snowy Garden, an outside zone where it constantly snows. There is no boss in this section.
- The Utility Tunnels, a series of underground tunnels, sometimes with vegetation on the walls. The boss of this section is SylBloom.
- The Canal, an outside zone where it constantly rains. The boss of this section is the Infected Grumbles.
- The Lost Hotel, a series of rooms similar to The Hotel from DOORS. There is no boss in this section.
- A variant called The Hallow Hotel can sometimes replace this section, with Hunt as its boss.
- The Substation, where the Stalker encounter takes place. There's also one Infected Grumble patrolling here.
- The Asylum, a building with many rooms. The boss of this section is The Chef.
- The Cavern, an underground section infested with Crawlies. There is no boss in this section.
After travelling through most of the sections in a random order (with The Substation guaranteed to appear after the section with Door 50), players will reach The Radio Tower, the last section of the floor, where the Vulture Bees lurks.

Entities
Entities are unnatural beings that inhabit The Lost Floors. Most of them pose as roadblocks and threats to hinder player's progress and usually attempt to kill or damage them in whatever ways they can.
See their respective pages for more information.
Main Entities
- Moonlight - A helpful entity that guides players throughout their journey. If players die, it will provide tips on how to survive the entity that killed them most of the time. Guiding Light also highlights important items and objects (such as levers and doors) after a certain amount of time has passed in a room.
- Starlight - A less helpful entity that will only appear after dying to Rage, Infect, a fall in The Attic section or when jumping off the starting train. Gives less helpful hints, but encourages players to continue anyways.
- Redlight - Only appears when dying to a Stalker or a train. Often makes mocking or sarcastic comments.
- Seek - The overarching antagonist of The Lost Floors, appearing in person to chase players in The Attic.
- Ribseer - Secondary antagonist of The Lost Floors. He appears in The Attic and chases players when he spot them.
- Stalkers - Secondary antagonists of The Lost Floors infected by Seek. They act as the boss of The Substation. They will move if not looked at, and will attack any player they reach.
- Infected Grumbles - Secondary antagonists of The Lost Floors infected by Seek. They act as the boss of The Canal. They crawl through tunnels and chase players on sight.
- SylBloom - A secondary antagonist of The Lost Floors, serving as the boss of The Utility Pipes. Like Figure, it is blind, but it uses echolocation to navigate. Chases players that are in its path.
- Figure - A tertiary antagonist of The Lost Floors, serving as the boss of The Basement. It is completely blind and thus relies on sounds and vibrations to locate players. Despite this, it is not the main threat for players. Can also appear in The Lost Hotel section.
- Hunt - Serves as the boss of The Hallow Hotel. Appears when too many lights are on and players are in the lit area.
- The Chef - Serves as the boss of The Asylum. Chases players it spots, dragging them to the kitchen and cutting them up if they get caught.

Recurring Entities
- Felk - Flickers the lights before rushing through several rooms up to an unopened correctly labelled door and opens it, breaking all the lights in the process and making the room a dark room. All nearby players that aren't hiding will die instantly.
- Infect - A more elusive entity, trying to ambush the player. Emits a scream before rushing through rooms. Kills players within range on sight.
- Eyes - Appears randomly upon entering a room, and are signified by a distinct sound effect and a bright blue/purple glow. The entity deals rapid damage if stared at and is able to teleport around the room. Eyes have a variant exclusive to The Snowy Garden that deals more damage.
- Screech - Can spawn in any dark place and reveals its presence with a “Psst!” and a slight screen shake. Players must look around in order to spot the entity and counteract the attack, otherwise it will deal 40 damage to them.
- IcyScreech - A variant exclusive to The Snowy Garden that does not care about light and will freeze the outline of the player's screen to signal its presence.
- Rush - Can rarely replace Felk, but behaves the same. Takes the role of Felk in The Canal.
- Rage - Breaks the lights one by one, then rushes through the rooms, killing any players who aren't hiding.
- Dupe - Poses as a door with a number label, but the number is always out of order and wrong. Players must not enter the wrong door, or Dupe will attack them, dealing 40 damage. A fake door may be identified by listening for growls or scratching sounds near the door and the wrong door number.
- Hunted - Approaches players from behind when they aren't looking, killing them if it manages to reach them. Looking at it causes it to back away.
- Crawlies - Spiders that attack players who do not crouch when approaching them. Using a light source on them causes them to flee.
