'''The Backdoor''' is a [[Floors|sub-floor]] that can be accessed from a side door in the exterior of the [[Lobby]], or through the "Create [[Elevator]]" Menu. As of March 30th, 2024, The Backdoor is only able to be entered if [[Player|players]] have previously obtained the Detour [[Achievements|achievement]] from entering ''[[The Rooms]].''[[File:Huntpromobetter.jpg|thumb|The poster used to promote The Backdoor that could be seen in-game from 3/15/24 - 3/30/24.]]
''The Backdoor'' was initially released on March 15, 2024 for the 2024 Roblox event, ''The Hunt: First Edition'', where it awarded players the "THE HUNT - First Edition" [[Achievements|achievement]] and a badge for the event. The [https://www.youtube.com/watch?v=ZU0owH2nxGk trailer] was uploaded to YouTube 1 day prior to the event. After the event concluded on March 30, 2024, the sub-floor remained in the game, although its entrance was changed, and also rewarded 2 different achievements, making "THE HUNT - First Edition" achievement unobtainable.

== {{Icons|Overview}} Overview ==
[[File:Backdoor new entrance .jpg|thumb|The entrance to ''The Backdoor'', blocked by [[Curious Light]].]]''The Backdoor'' entrance can be found by exiting [[Lobby|The Lobby]] via the front doors, taking a right, and proceeding until a player reaches an opening in the gate. If a player has not entered [[The Rooms]] yet, a glowing [[Curious Light]] themed barrier will be seen blocking the opening and text will appear stating that players need the Detour [[Achievements|achievement]] (which is obtainable by entering The Rooms for the first time) to proceed. Behind the gate is a door acting as an elevator, which holds up to four players. During ''The Hunt: First Edition,'' players could've instead accessed ''The Backdoor'' by entering any of the [[elevator]]s in the once-barricaded corridor in The Lobby, which contained a sign which explained how players could've obtained "THE HUNT: First Edition" [[Achievements|achievement]].

''The Backdoor'' contains its own cast of unique [[List of Entities|entities]], with similar, yet different ways of attacking players compared to the entities that are found within [[The Hotel]]. [[Containers|Drawers]] can be found throughout ''The Backdoor,'' and may contain [[Gold]], [[Room Key (The Backdoor)|Room Keys]] (in rooms with locked doors), or [[Vial of Starlight|Vials of Starlight]].

[[Hiding|Closets]] and Time [[Levers|Lever]]s also appear throughout ''The Backdoor''. 

''The Backdoor'' features a unique timer mechanic. Once players open Door -50, they will be given one minute to complete the entire floor. The amount of time players will have to complete the floor can only be increased by players interacting with Timer Levers, which appear randomly throughout ''The Backdoor'', and will add either 30 or 60 seconds depending on the time remaining when the lever spawns. Door -50 will always have a Timer Lever. The amount of time players have remaining can be seen above Timer Levers and on the front of each opened numbered door. 

As players' remaining time decreases, the background music changes accordingly, becoming more intense and frantic. If players run out of time, Haste will spawn and begin chasing them, instantly killing any players it reaches. Haste will disappear immediately if players pull a Timer Lever before it succeeds in killing them.

''The Backdoor''<nowiki/>'s appearance is similar to The Hotel, with the most noticeable differences being that ''The Backdoor'' has lightbulbs instead of wall lamps, brighter lights and a different wood for its interior.

The final door, -01, contains the [[Bottle of Starlight]], which players can purchase for 100 Gold, as well as a Time [[Levers|Lever]]. 

Another numbered door, 0000, is located at the back of -01. Once any player interacts with it, a cutscene will play where the door will shatter into pieces, revealing a yellow glowing portal behind it. Then, all players (including those who are dead and spectating) will be granted the "Other Way Around" achievement (or "THE HUNT: Escape The Backdoor" if it's before THE HUNT event ended), if they do not own it already. After a 15-second skippable intermission, all players will be teleported to [[The Reception]] with the use of an ancient rock portal, and will be able to continue their run in The Hotel. Players will retain their remaining [[health]], and any [[items]] in their inventory, but they will not be able to use the [[Shops|Pre-Run shop.]]

{{AnyIcons|EntityIcon.png|Entities|mobile=Yes|format===|caption=Entities}}
Entities are unnatural beings that inhabit ''The Backdoor''. Most of them pose as roadblocks and threats to hinder players’ progress and usually attempt to kill or damage them in whatever ways they can.

'''Blitz''' is a hostile entity that appears in '''The Backdoor'''.

== {{Icons|Overview}} Appearance ==
''Blitz'' takes on the appearance of a distorted green face, similar to that of [[Rush]]. Its face turns pink and distorts further when rebounding, with wider eyes and smile, while still having a small green "aura." When crucified, Blitz will repeatedly switch between its rushing form and its rebounding form.

== {{Icons|Behavior}} Behavior ==
''Blitz'' has a behavior nearly identical to that of [[Rush|Rush’s]]; when ''Blitz'' spawns, the lights in the current room will flicker to indicate its arrival. It will rush through and attack all players in its line of sight while producing a distorted screeching sound. This attack will deal fatal damage to targeted players, though those under the effect of a [[Vial of Starlight|Vial]] or [[Bottle of Starlight]] may survive the attack.

Unlike [[Rush]], after passing through all rooms, ''Blitz'' has a chance to turn pink and rebound, similar to [[Ambush]]. ''Blitz'' can rebound multiple times before leaving, depending on the time left, although most commonly, it will rebound only once or twice.

Unlike [[Rush]], ''Blitz'' will not open the door to the next room.

''Blitz'' will never rebound if the timer is below 30 seconds.

== {{Icons|Trivia}} Strategy ==
Because ''Blitz'' acts nearly the same way as Rush, hiding in a closet will guarantee a player's survival. Similar to [[Ambush]], players should be cautious of Blitz's rebounding until its screaming sounds can no longer be heard. This is because ''Blitz'' can still rebound after passing through the next unopened door.

Players who are avoiding ''Blitz'' can hide inside a closet for as long as needed due to the absence of [[Hide]] in the Backdoor. If a player cannot find a closet in time they are able to use a [[Vial of Starlight|Vial]] to survive the attack or find a safe spot. Note: This will only work if the player has more than 80 health points, otherwise they will not receive the extra health buff.

== {{Icons|Trivia}} Trivia ==
* The decal name of Blitz's green appearance is "[https://www.roblox.com/library/16602023490/Images-rushs-brother-LORE-LORE-LORE rushs brother LORE LORE LORE]".
** Similarly, its pink appearance is named "[https://www.roblox.com/library/16630718245/Images-rushs-sister-LORE-LORE-LORE rushs sister LORE LORE LORE]".
* ''Blitz'' means "flash or lightning Bolt" in German.
** However, it is most likely named after the english word, as it means "something that repeats".
* Before deciding on a final name, ''Blitz'' was referred as "Grush", a portmanteau of Rush's name and the color green.{{Fact}}
* Similar to Rush, it is possible to hide from ''Blitz'' without entering a closet. A player can enter a side room (that is not occupied by the ''Vacuum'') and hide behind a wall to survive.
** However, players cannot unlock the "In Plain Sight" [[Achievements|achievement]] via this method. This is likely an oversight by ''[[DOORS]]''<nowiki/>' developers.
* Because ''Blitz'' is Rush's counterpart, all of its sounds are Rush's but sped up. 
** The sped up sounds are really similar to the [[2023 April Fools Event|SUPER HARD MODE]] rush clone audio cues.
** It is the only Doors entity to share the same jumpscare audio from another entity (which is Rush's but sped up).
** The sound that Blitz makes while being crucified is almost, if not identical to the base speed of Rush and Blitz's distant and nearby audio cues.
* Whenever a player dies to ''Blitz'' for the first time, [[Curious Light]] says "She said we should call that one ''Blitz''." It's currently unknown who 'she' is.
* ''Blitz'' uses any pronouns. <ref>[https://x.com/LightningSplash/status/1834067067978330378?t=cu33gPzZ-KKx_1qDiCnc2A&s=19 Q: whats Blitz pronouns A: any] -Lsplash, Twitter</ref>

<option>{{Quote|The ''Lookman''? It's very similar to another entity you've definitely encountered.|[[Curious Light]]}}</option>
</choose>
The '''Lookman''' is a hostile entity that appears in '''The Backdoor'''.

== {{Icons|Overview}} Appearance ==
The ''Lookman'' takes on the appearance of a tall, shadowy humanoid silhouette similar to [[Shadow]], but with glowing white eyes that turn purple when looked at. When crucified, The Lookman distorts, and its eyes become red and widen drastically, while also looking slightly upwards.

== {{Icons|Behavior}} Behavior ==
The ''Lookman'' behaves similarly to [[Eyes]] because the whole character is a reference to the beta version of Eyes, with the same name and design. The only difference is that the ''Lookman'' damages a player once, then teleports to a different position. Furthermore, its audio cues are very quiet, making it difficult for players to detect the presence of the ''Lookman''.
 
It has a chance to spawn in most rooms and makes a low rumbling noise. If players look at its eyes, it will attack them, briefly darkening their vision and teleporting to a random place in the room while making a thumping noise and causing the lights to flicker. The ''Lookman'' will despawn when the next door is opened. 

== {{Icons|Trivia}} Strategy ==
The ''Lookman'' only attacks if players look directly at its eyes. Thankfully, the ''Lookman'' has a tall stature and thus can be easily avoided by looking down slightly to avoid eye contact.

The ''Lookman'' has a tendency to spawn next to the exit door of a room. Players can use this to their advantage and save time by listening for its rumbling cue when in rooms that have multiple possible exits, such as the ''Maintenance Hallway'' rooms, and it is especially useful in navigating dark rooms. However, players will lose this navigational niche if it teleports away to a different location.

== {{Icons|Trivia}} Trivia ==
* The ''Lookman''<nowiki/>'s design is based off of ''Eyes'''<nowiki/> original design.
** The ''Lookman''<nowiki/>'s name is derived from an older version of Eyes' name.<ref> [https://twitter.com/LightningSplash/status/1699829226470269179?t=0j58sJ5lGh9dFOa_BpaHJA&s=19 "also, 'Eyes' was originally called 'Lookman'" -LSPLASH, Twitter] </ref>
* The ''Lookman'' is the third of six entities featured on the ''[[DOORS]]'' icon, the second being Dupe, the first being Seek, the fourth being the Gloombats, the fifth being Glitch, and the sixth being Rush.
* The ''Lookman''<nowiki/>, like Eyes, can't hurt players while [[hiding]].
* The ''Lookman'' <nowiki/>'s design looks similar to ''[[Shadow]]'', though this is probably a coincidence.
* When dying to the ''Lookman'' when spawned by [[Candy]] in the Hotel or Mines using the Trick or Treat Modifier, there will be no death message.
* When the player slowly moves the view camera at the Lookman, its eyes can be seen quickly lighting up.
* The ''Lookman'' <nowiki/>'s crucifix badge is a reference to Dora the Explorer, being a rephrase of the common quote “Swiper no swiping!” And Swiper saying “Oh man!”

'''Haste''' is the main antagonist of '''The Backdoor''', and acts as a time limit.

== {{Icons|Overview}} Appearance ==
''Haste'' takes on the appearance of a red human skull with black, hollow eyes and a grainy 'skin' texture. Its colors are similar to that of a spectrogram image. When crucified, Haste's mouth opens wider. Its 'body' stretches and distorts during the process.

== {{Icons|Behavior}} Behavior ==
''Haste'' will spawn when the Backdoor's timer runs out. It will highlight a player's screen with a red haze and begin to approach from behind, killing a player instantly if caught. If a [[Timer Lever]] is activated to increase the time during ''Haste''<nowiki/>'s attack, it will immediately despawn. Do note that you can know how close ''Haste'' is to players by looking backwards, as you can see ''Haste'' through walls.

== {{Icons|Trivia}} Strategy ==
''Haste'' requires the most attention out of any entity in the Backdoor and is the main source of difficulty in the Backdoor. Players who do not look for or activate levers can very easily be killed by ''Haste''. It is important that players keep an eye out for hidden Time Levers, such as those in side rooms and out of plain sight, and prioritize their time both progressing through the [[Floors|floor]]'s rooms and collecting [[gold]] and [[items]].

Even if players are being targeted by ''Haste'', they may still find Timer Levers by exploring rooms to extend their time. Any extension to the time by activating a switch will immediately despawn ''Haste''.

== {{Icons|Trivia}} Trivia ==
* ''Haste'' is a reference to [https://spookys-jump-scare-mansion.fandom.com/wiki/Specimen_9?so=search Specimen 9] from ''Spooky's Jump Scare Mansion''. Both are red skulls, have near identical death screens with repeatedly-displayed mantras ("TO TAKE THE DEAD" and "NO TIME LEFT" for Specimen 9 and Haste respectively), both kill players in one hit, both can be seen through walls, and both appear under specific circumstances related to time.
*Haste's near sound bares similarities with Siberia Hell sounds, accompanied with streamer IShowSpeed screaming when it is near.
* ''Haste'' was planned to be added to ''[[DOORS]]'' since September 2022 but was scrapped.
* ''Haste'' is the loudest entity in ''[[DOORS]]''.
* ''Haste''<nowiki/>'s original mechanic was to attack players if they stalled in a room too long, forcing them to hide. The developers thought the mechanic made no sense, so the entity was shelved.<ref name="Haste Scrapped">[https://x.com/LightningSplash/status/1819832046627246295 LSPLASH on X: "@OGNface 3. after stalling in a room for too long it chased down players and made you hide... which fundamentally made absolutely 0 sense whatsoever, so it was shelved" / X]</ref> This feature seems to be used by Dread, albeit a bit differently.
* Similar to [[A-90]], ''Haste'' is a client-sided entity, meaning there will be a unique instance of ''Haste'' for every player.
** As a result, players who are dead and spectating the game will not see ''Haste'' and any of its effects.
** If a player crucifies ''Haste'', they will not kill other players even though they have already been caught and should be dead.
** Despite ''Haste'' being a client-sided entity, exploiters aren't able to bypass the time limit by disabling ''Haste'' on their client.
* If a player were to be killed by ''Haste'' during the intermission whilst returning to [[The Hotel]], they will still be able to exit normally but will lose any items they had on them.
* Haste's jumpscare sound consists of the default player death sound being played repeatedly.
* Curiously, players can still interact with time levers during ''Haste's jumpscare. This will despawn it and players won't die.
* Before ''The Hunt'' event ended, when ''Haste'' was on your screen and it says "NO TIME LEFT", you were still able to move for a couple more seconds before ''Haste'' actually kills you.
** After ''The Hunt'' event ended, if ''Haste'' reaches you fully and on the screen it says "NO TIME LEFT", you are no longer be able to move.
* As of the Content Update, it is now possible to crucify ''Haste'' using the [[Modifiers|Make Haste]] modifier.
** This will reset the timer to 1 minute.
** Interestingly enough, ''Haste'' doesn't require a [[Crucifix]] to be in player's hand, meaning you can hold any item or even not hold any, but still crucify it (if you have a [[Crucifix]] in the inventory).
* If Haste is brought to the hotel via the "Make Haste" modifier, players can outrun it with some of the speed modifiers.
** Although, if the floor's timer is left at 0 for too long, all players are automatically killed.

{{Quote|The vacuum has no oxygen, and I'm told you need oxygen to survive.|[[Curious Light]] referring to the vacuum.}}
'''The Vacuum''' is a major hazard in [[The Backdoor]].
== {{Icons|Overview}} Appearance ==
The Vacuum's exterior appears to look like a regular door, indiscernible from the outside, similar to [[Dupe]], though it differs in the fact that its interior appears to be a hollow vacuum, which, as described by [[Curious Light]], "has no oxygen." The vacuum presumably surrounds the entirety of the Backdoor. It is unknown if it could also surround [[The Hotel]] although it is unlikely as there is a courtyard and rain on it. Also, given the existence of [[The Mines]] and [[Floor 3]], this seems to be a feature exclusive to the Backdoor.

== {{Icons|Behavior}} Behavior ==
''The Vacuum'' is not openly hostile, and is only triggered when one opens a side door of one of the rooms. Upon doing so, the vacuum will start pulling nearby players toward the door, and if entered, they will be instantly killed. Players can still walk away from the door before getting sucked in to escape. The way to detect Vacuum is by looking at the screens, if the door has a screen then it is real, if it does not then it could be a door with Vacuum.

In addition to the vacuum doors, some rooms may have a giant hole in them, exposing players to the vacuum. However, players cannot die to The Vacuum from these holes as there will always be objects preventing the player from being sucked in.

== {{Icons|Trivia}} Trivia ==
* A line of the [[Curious Light]]'s dialogue saying "...[The Backdoor is] somewhat forgotten, too. Some parts seem to be missing entirely." seems to imply that the doors leading out to The Vacuum were created as a result of parts of the Backdoor being "forgotten". It is currently uncertain what the word "forgotten" means in this context.
* ''The Vacuum'' is thought to be based off of [[Dupe]] and [[Subspace Tripmine]] in some fashion.
* ''The Vacuum'' may also be possibly connected in some way to Void, though this is purely speculation.
* A [[Giggle]]’s body can be thrown into The Vacuum, shortly revealing that The Vacuum is a box room, similar to [[Dupe]] and side rooms.

[[File:Lockbackdoor icon.png|thumb|125x125px| The Backdoor padlock.]]

=== Locked Rooms ===
Locked Rooms require a [[Room Key|''Backdoor'' Room Key]] to progress into the next room. The required Room Key may be found in or on top of [[Containers|drawers]] or on the floor. 

=== Dark Rooms ===
Occasionally, rooms may spawn without any light, accompanied by a mysterious sound cue (similar to the one present in [[The Hotel]]). However, unlike The Hotel, there is no entity (e.g. [[Screech]]) that spawns exclusively in dark rooms. This only causes a visual hindrance.

=== Timer Lever Rooms ===
Rooms that contain a Time [[Levers|Lever]], which can be activated to add to the timer of ''Haste'' spawning. They can be found in normal rooms or in side rooms.

=== Entrances ===
==== Elevator (Removed) ====
{{Main|Elevator}}
Before ''The Hunt: First Edition'' ended, when starting a run, an Elevator teleported players to Room -51. It opened itself once all players have loaded into the game and closed automatically. This Elevator did not feature the [[Shops#Pre-Run Shop|Pre-Run Shop]], and the song [[Soundtrack|''Elevator Jam'']] did not play. Whilst in the [[Lobby]], the elevator doorframe had a blue outline, the same as the event area entrance, as that was the brand color for the ''The Hunt: First Edition'' event. 
[[File:BackdoorEntrance.png|thumb|The Backdoor Entrance after The Hunt.]]

==== Backdoor Entrance ==== 
At present, provided they have the [[Achievements|Detour achievement]], players can go outside the Lobby's doors, take a right, and pass through to enter ''The Backdoor''. Once players are loaded in, they appear just on the doorstep of the Lobby's backdoor. The door will shut after a few seconds, like the [[Elevator]]. Similar to the elevator, it does not feature the Pre-Run Shop, and the song Elevator Jam does not play.[[File:The Backdoor.png|thumb|Room -51.]]

=== Room -51 ===
Room -51 is the first room in ''The Backdoor''. Tables, [[Containers|drawers]], [[Hiding|closets]], and decorative boxes may generate within the room. A [[Room Key]] generates on top of a table or set of drawers behind a fenced-off corner. Players must crouch beneath the fence and collect the Room Key to progress to Room -50.  This is the only room in The Backdoor where there is no time limit, as the timer does not start until the door to Room -50 opens.
[[File:The Two Gates Room.png|thumb|The Two Gates Room.]]

=== Two Gates Room (Room -50) ===
The Two Gates Room, or Room -50, is guaranteed to be the first room to generate after Room -51. The Two Gates Room consists of two gates (one of which may be closed), with a wall running between them. A guaranteed Time [[Levers|Lever]] is attached to the front of said wall, and upon a player interacting with it, one minute will be added to the in-game timer.  
The Two Gates Room after Room -50 can reappear, however it usually will have a difference (such as a lack/different position of a Timer Lever, or one of the gates may be opened or closed).    [[File:The BackDoor Final.png|thumb|Room -01.]]

=== Room -01 ===
Room -01 is the final room in ''The Backdoor''. This room will generate a Time [[Levers|Lever]] next to the entrance. The room's centerpiece is the [[Bottle of Starlight]], which floats above a pedestal surrounded by a pile of bricks. Players can purchase it for {{Gold|100}} [[gold]]. There is a staircase on each side of the pedestal, leading to a raised floor. Door 0000 is situated behind an open gate on the back wall. Once a player opens Door 0000, all players (whether dead or alive) will be teleported to [[The Reception]] after a skippable 15-second intermission. An empty doorway will appear behind them presenting signs of [[Curious Light]], this empty doorway also appears when a player enters or exits [[The Rooms]]. 

=== Secondary Locations ===

==== Multi Gate Room ====
[[File:The Several Gates Room.png|thumb|The Multi Gate Room.]]
The Multi Gate Room is a room with many gates, which spawns frequently throughout a run. The room consists of up to eight gates, with a door behind each of them. Only one of these doors will allow progression to the next room. This room may spawn as a dark room, and Timer Levers may spawn in this room.  
[[File:Low room BackDoor.png|thumb|The Wall Room.]]

==== The Wall Room ====
The Wall Room is a room that players are likely to encounter during a run. It is a large room blocked by a low wall. Players will have to crouch for an extended period of time underneath the wall, which contains many scattered boxes. This room may spawn as a dark room.

* Time [[Levers]] can't spawn in this room.

[[File:Room with pipes BackDoor.png|thumb|The Maintenance Hallway.]]

==== The Maintenance Hallway ====
The Maintenance Hallway is a room that players are likely to encounter during a run. It consists of 4–12 doors, with only one door leading to the next room. There will be yellow and black tape at each doorway, and pipes at both ends of the room. This room may spawn as a dark room, and Timer Levers may spawn in this room.   
[[File:Ladder room BackDoor.png|thumb|The Staircase Room.]]

==== The Staircase Room ====
The Staircase Room is a room that players are likely to encounter during a run. This room consists of up to 10 sets of stairs, running upwards and downwards. Each stairway will lead to a floor that contains a door. Only one floor will contain the proceeding door. This room may spawn as a dark room. Timer Levers cannot spawn in this room, although they may generate within side rooms. 

{{AnyIcons|Soundtracks.png|In-game soundtrack|format===|mobile=Yes|caption=In-game soundtrack}}
See [[Soundtracks]] for a full collection of sounds.

== {{Icons|Bugs}} Bugs ==
* Players may be able to hide in drawers to avoid ''Blitz'' (this is not consistent) unless the drawer has a coin.
* There is a rare bug that can cause a fake door to have 2 handles.<ref>https://doors-game.fandom.com/wiki/File:Capture_d'écran_2024-03-22_210528.png?_rcid=51120</ref> This can also happen in [[The Hotel]] and [[The Mines]].
* Sometimes, even when ''Blitz'' is not rebounding, it will still show the rebound animation and sound.
* There is a bug where the ''Lookman'' can spawn slightly lowered in the ground.<ref>https://doors-game.fandom.com/wiki/File:Lookman_in_the_ground.png</ref>
* If a player has a weak internet connection or is playing on low graphics, ''Blitz'''s glow may remain in rooms until lighting updates.
* If a player does not have the "Detour" [[Achievements|achievement]] and glitches through the barrier blocked by Curious Light and clip some invisible walls, a private error message will pop up saying "You need to unlock "Detour" to access elevators in the Backdoor!".
* ''Blitz'' can leave a lamp lit even after breaking it, although the glitched lamp will not emit any light.
* There is a bug where when entering a room with unnumbered doors fails to generate the door to the next room, which is replaced by a regular unnumbered door or a giant black box, softlocking players until ''Haste'' spawns.
* On low graphics settings, one can semi-accurately spot whether or not a door is an instance of Vacuum or not due to light pouring out from under the door and nearby walls. Though, this only works when the room behind the door has lights, therefore it is not fully accurate when searching for splinter rooms.
* If a player goes forward just as they opened a locked door, they can go up through the ceiling and end up outside the room, softlocking them unless they fall into a position where they can fall off the map, and then [[Glitch]] will teleport them back.
** However, in some cases, they won't go through the ceiling and be stuck in mid-air. For this to happen, the next room has to have one or more closets. In this situation, the player has to walk backwards to the closet and hide into it. After exiting the closet, they are back to the floor and can progress again.
* If a player stalls/runs away from Haste for too long, it will kill them instantly with no jumpscare, bypassing god mode and crucifixes. 

== {{Icons|Trivia}} Trivia == 

* ''The Backdoor'' is the second [[Floors|sub-floor]] to be added to ''[[DOORS]]'', with the first being [[The Rooms]].
* Before the post-Hunt update, the ''Backdoor'' was in [[Lobby|the Lobby]], did not require the [[Achievements|"Detour" achievement]], and had an elevator. 
** There was a sign in the Hunt lobby which notified players that once the event was over, the ''Backdoor'' would become more difficult, although no major changes seem to have been made.
* [[RediblesQW|Redibles]] confirmed that ''The Backdoor'' was fully planned, developed, and released in 2 weeks and most of the ideas used in the Backdoor are recycled scrapped ideas.<ref>[https://x.com/RediblesQW/status/1837818747463041381?t=6PRGkyjy1BG1aY-5jPNxTg&s=19 "fully planned, developed, and released in two weeks...] -Redibles, X</ref>
* ''The Backdoor'' is canonical to the ''DOORS''' ''Lore''.<ref>[https://twitter.com/LightningSplash/status/1768703678943199463 "..the floor itself is canon!"] -LightningSplash, X</ref>
* The exit door in -01 is an unlabeled -00 door. This can only be seen using exploits or by looking through the game files.{{Exploiting Inline}}
* The achievement description for "Other Way Around", reading "Yeah, I've got time." is a reference to The Incredibles, to the Bob Parr's line.
* ''The Backdoor'' is currently the fastest floor to clear, including [[2024 April Fools Event|RETRO Mode]]. (April Fools 2024 Event) The average time to clear the ''Backdoor'' is around 7 minutes and 40 seconds, whereas the average time to beat [[2024 April Fools Event|RETRO Mode]] is between 9 1/2 minutes to 10 1/2 minutes. Ten minutes is impossible as the Drakobloxxers arrive in 600 seconds, which is 10 minutes.
* If the timer has over 2 minutes, the main ambience will not play, due to the fact it is a soundtrack last for almost only 2 minutes.
* Time remaining on the timer affects some odds:
** If there is less than 1 minute left, ''Blitz'' will rebound less.
** If there is less than 30 seconds left, ''Blitz'' will never rebound, so players can keep going and find a lever faster. This is also the same when there is literally NO time left.
** Time [[Levers]] also are affected if there is less time left.   
*** If more than 2 minutes remain, no time [[Levers|levers]] will spawn, because players have enough time.
*** If a lever that spawns when there are more than ~65s left, it will add 30 seconds.
*** Otherwise, if there are less than ~65s left upon spawning, it will add 60 seconds. However, if the timer goes below 65 seconds when the time lever spawned before it was 65 seconds, it can still have 30 seconds.
* Only one Timer Lever may be loaded at a time. The next Timer Lever may generate as soon as the previous one unloads given it meets the time constraint for it to spawn.
** Since [[The Glitch|Glitch]] unloads 4 rooms behind player, and the game always generates 1 room ahead, Time [[Levers]] will spawn at minimum 5 rooms apart from each other (excluding the guaranteed spawns at Doors -50 and -01). Therefore, if a player flipped a Time [[Levers|Lever]] in the current room or in the previous 3 rooms, there is no need to scour the side rooms for more levers.
** '''As of [[The Content Update]], this is no longer the case. '''Time [[Levers]] will now spawn more frequently, possibly every room, until one lever is flipped, at which point generation goes back to every 5 rooms.
* The ambient sounds will play when the timer hits a multiple of 15, excluding the "tension" audio that plays on the last 30 seconds. 
** This will only happen if there are less than 2 minutes left, as the audio only starts at that time.
* ''The Backdoor'' might get a touch up in the future.<ref>[https://x.com/LightningSplash/status/1768703678943199463 Q: "Will you expand the backdoor to a full floor with 100 doors?" A: "Nah, we might touch up the backdoor just a bit though"] - Lsplash, Twitter</ref>
* Like [[The Rooms]], players are not able to use revives in ''The Backdoor''. 
** Prior to [[The Mines Update]] however, players could still revive as long as the timer is above 00:15.
* ''The Backdoor'' will not receive any modifiers directly.{{Cite X|link=https://x.com/LightningSplash/status/1840942845315694897|author=LightningSplash|quote=no, Backdoors is meant to not have modifiers}} However, certain mechanics from ''The Backdoor'' are modifiers.
* If a player escapes ''The Backdoor,'' they will be granted 50 [[knobs]].
* It is almost guaranteed to get all room types in a single run.
* Similarly to [[The Rooms]], when exiting ''The Backdoor'', the game counts it as a floor, with a parenthesized "1" next to it. 
** As of now, The Rooms no longer has a parenthesized "2", because it was changed to "1", so that people won't get confused about The Mines and The Rooms.
* Similar to [[The Rooms]], [[Hide]] is not present in ''The Backdoor'', so players can hide for as long as they wish (until Haste spawns).
* When exiting ''The Backdoor'', it plays the same animation as when exiting [[The Rooms]].
* Miscellaneous entities don't spawn in ''The Backdoor'', such as [[Jack]], [[Timothy]], and [[Shadow]] (excluding [[Glitch]]).
* When ''Haste'' spawns, it will print "erm.. hello bro" into the console.
* Judging by the ''Backdoor's'' design and location, the floor is most likely the Basement floor of the Hotel. This is proven by stairs that lead down to an area with ''Backdoor'' decorations, including a blocked door with a broken timer, in the [[Lobby]].
* A quote from [[Curious Light]] states that The Backdoor is a very old place, however, not any older than [[The Hotel]], despite being in much worse shape and almost forgotten, and some things missing within it.<ref>https://youtu.be/Uq2yRbbCR0I?si=1rpZnB04j9k0h1FG&start=65</ref>
* The ''Blitz, Oh'' modifier is most likely a reference to the character ''Blitzø'' from [https://en.wikipedia.org/wiki/Helluva_Boss ''Helluva Boss''].
