->''"As far as Foundation adapted works, it's one of the biggest and most comprehensive."''
-->-- '''Dr. Gears''', [[https://scp-wiki.wikidot.com/forum/t-646655/the-scp-containment-breach-update#post-1765583 About the game.]]

''SCP - Containment Breach'' (found [[https://scpcbgame.com/ here]]) is an independently developed SurvivalHorror game based on the Website/SCPFoundation wiki, and spin-off of ''VideoGame/SCP087-B''. Many of the tropes which apply to [[Characters/SCPFoundation individual SCPs]] naturally apply here, too.

You take on the role of a [[CannonFodder D-Class personnel]], designated D-9341, who is assigned to an experiment with [[https://scp-wiki.wikidot.com/scp-173/ SCP-173]]. You're directed into the chamber with two other D-Class personnel, all standard procedure...

... And then everything goes straight to Hell. The doors malfunction, the lights go out, and suddenly you're smack in the middle of a full-scale [[TitleDrop containment breach]]. While you might consider yourself fortunate that the LivingStatue didn't murder you on the spot, that's not the end of it. It can travel through the site's ventilation system, meaning that it can pop out at any moment in any room.

Armed with whatever you can find along the way, you have to make your way through the facility, dodging 173 and whatever other horrors have been released while trying to find a way out of this nightmare.

Here's the page for its fan-made spin-off/modification ''VideoGame/NineTailedFoxMod'', and here is the page for the multiplayer spin-off game, ''VideoGame/SCPSecretLaboratory''.

A SpiritualSuccessor to the game, ''[[https://www.scp-unity.com/ SCP: Unity]]'', was in development until being cancelled due to the developer's health issues. Another such successor, ''[[https://scprecontainment.com/ SCP: Recontainment]]'', is in development, but was also cancelled.
----
!!''SCP: Containment Breach'' contains examples of:
* AdaptationPersonalityChange: An interesting example with [[https://scp-wiki.wikidot.com/scp-049/ SCP-049]]. At the time he was added to the game, his entry on the wiki characterized him as a SilentAntagonist with a sense of BlueAndOrangeMorality; despite this, the game made him more of a ColdHam who is quite chatty while pursuing the player around the facility. The game's version of the character became [[invoked]]AscendedFanon when 049's article was rewritten in May 2018, not only making this personality change official but bringing back the same voice actor, Aaron [=McKee=] ([[https://www.youtube.com/user/TheVolgun TheVolgun]]), to read his lines.
* AffablyEvil: [[https://scp-wiki.wikidot.com/scp-049/ SCP-049]], judging from his quotes. He may also be ObliviouslyEvil.
* AllThereInTheManual: While the game does provide documents explaining the nature of the [=SCPs=] you come across, getting those generally requires entering the cells in the first place. Having read the wiki and knowing what the designations refer to helps immensely in avoiding walking into rooms with murderous occupants. [[EverythingIsTryingToKillYou Which pretty much describes all of them.]]
* AmbiguousEnding: One ending has D-9341 finally escape the facility… [[spoiler:only to run into [[RenegadeSplinterFaction Chaos Insurgency]] agents, who take him with them. Whether this is a better or worse fate than death or staying with the Foundation is very, very unclear]].
* AmplifierArtifact: [[https://scp-wiki.wikidot.com/scp-914/ SCP-914]] when set on Fine or Very Fine, though this can backfire depending on the object.
* AndIMustScream: One room in [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]]'s PocketDimension is filled with what look like coffins, from which muffled sobs and whispers can be heard. Presumably these are some of his victims, kept alive indefinitely so he can [[ColdBloodedTorture torture them at his leisure]].
* AnimalisticAbomination:
** [[https://scp-wiki.wikidot.com/scp-939/ SCP-939]], a VoiceChangeling that uses the voice of its victims to draw more prey near in order to devour them.
** The feline-like creature which stalks the player in [[https://scp-wiki.wikidot.com/scp-860/ SCP-860-1]].
* ApocalypticLog: An agent by the name of Izumi Junko got sent into [[https://scp-wiki.wikidot.com/document-860-i-and-ii/ SCP-860-1]] at some point before the player enters it. She left behind notes which detail several creepy events happening, such as their headset playing soft music and an almost comfortable atmosphere. The log ends by specifically mentioning D-9341, telling them that she is expecting him.
* ArcWelding: The game seems to imply a correlation between [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]] and [[https://scp-wiki.wikidot.com/scp-895/ SCP-895]]. Approaching the latter will spawn the former, and one area of his PocketDimension (the part resembling a UsefulNotes/WorldWarI trench) has several of the coffins dotted around the map. 106's face is among the BrownNote images displayed by 895.
* ArsonMurderAndJaywalking: One of the "cheery" Channel 3 radio messages go over the "Deadly Seven", covering several dangerous substances you could consume, including spiders.
--> '''Message:''' When dining at the facility cafeteria, always remember to check your ration for the deadly seven. Strychnine, Arsenic Trioxide, Nitrobenzene, Mercury, Epichlorohydrin, Acetone Thiosemicarbazone, and spiders. Stay healthy! Stay vigilant.
* ArtificialStupidity: [=NPC=]s frequently get stuck on stairs, which can be good if you're trying to escape a hostile [=SCP=]. Sometimes they'll also spawn in rooms that aren't connected to the player's location, such as a security checkpoint, and will be trapped inside until the player leaves and they despawn.
* AsianFoxSpirit: Invoked; Mobile Task Force Epsilon-11's colloquial name is "Nine-Tailed Fox".
* BadassNormal: Despite you being a helpless Class-D with no special abilities, you can still contain [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]], turn off the Alpha Warheads, and successfully dodge gunfire from both MTF units and Apaches.
* BigBadEnsemble: While [[https://scp-wiki.wikidot.com/scp-173/ SCP-173]] is the first and most recurring enemy, [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]] can also emerge from the ground or ceiling at any moment. [[https://scp-wiki.wikidot.com/scp-079/ SCP-079]] is also a recurring enemy, as it will attempt to hinder the player's process through various ways and [[spoiler:is also revealed to be the secondary cause of the containment breach]].
* BilingualBonus: One of the quotes of the Nine-Tailed Fox when they search for the player has them curse in Swedish, saying "Jävla helvete[[note]]Fucking hell[[/note]], come out!"
* BornLucky: [[spoiler:One ending has you possibly classified as a SCP for this reason.]]
* BrownNote:
** Viewing [[https://scp-wiki.wikidot.com/scp-895/ SCP-895]]'s CCTV monitor for too long will kill you, and your gaze is actively drawn to it when you're in the same room (it also doesn't help that [[https://scp-wiki.wikidot.com/scp-079/ SCP-079]] can broadcast its feed on any CCTV monitor throughout the facility).
** [[https://scp-wiki.wikidot.com/scp-1025/ SCP-1025]] will give you whatever medical condition you read about [[ViolationOfCommonSense if you're dumb enough to read it]].
** Similarly, you'll go [[LaughingMad completely insane]] if you go near [[https://scp-wiki.wikidot.com/scp-012/ SCP-012]], ultimately bleeding out in front of it while trying to complete it. It doesn't help that you're drawn towards it. Thankfully, it ''can'' be avoided by utilizing [[https://scp-wiki.wikidot.com/scp-714/ SCP-714]].
** If you stand too close to [[https://scp-wiki.wikidot.com/scp-1048 SCP-1048-A]], it will emit a loud, high-pitched sound that causes you to die from [[BodyHorror ears suddenly growing all over your body, including in your airway]].
* CantMoveWhileBeingWatched: SCP-173, natch. It behooves you to make sure there is something between you and it when you have to blink, lest you find your neck snapped.
* CheckpointStarvation: In Euclid difficulty, you can only save at computer terminals which are scattered across the facility. The Heavy Containment Zone in particular has very few of these, and most of them are in rooms requiring high-level key cards to access.
* ControllableHelplessness: [[spoiler:Trying to escape through Gate B always results in your death. SCP-682 escapes containment just as you arrive at the gate and the Foundation decides to nuke the facility to try and kill him (it doesn't work), with D-9341 getting caught in the blast. Once you go up to Gate B, there's no stopping the detonation. Even if you disable the nukes before going up there, right after it is announced that the the nukes cannot be detonated, a troop of MTF units shoot you.]]
* DeadlyGas:
** Decontamination gas is sprayed in certain areas as a means of slowing down [=SCPs=]. Unless you're wearing a gas mask, it causes you to cough and blink rapidly, which will make you easy pickings for [[https://scp-wiki.wikidot.com/scp-173/ SCP-173]]. Standing too long in it will eventually cause you to die due to suffocation.
** Take too long to get out of your room in the intro and... [[PressStartToGameOver you'll get locked in with gas everywhere.]]
* DevelopersForesight:
** Go ahead, put anything you can think of into SCP-294. You're bound to get some result.
** Likewise, there are plenty of ways to use SCP-914 in creative ways. Perhaps the most noteworthy is the fact that you can refine ''yourself'' if you sprint into the Input booth before it closes, which will [[PressXToDie kill you]] or invert your controls depending on the setting.
** There's a unique message for just about every way you can die in the game, sometimes even taking into account which room you're in when it happens.
** Disobeying [[{{Jerkass}} Agent Ulgrin]]'s orders in the prologue can get you shot or gassed, depending on how often you piss him off. Likewise, disobeying Security Chief Franklin in 173's chamber in the same prologue will lead to him ordering a guard from a high vantage point to kill you.
* DiscOneNuke: It is extremely common to find [[https://scp-wiki.wikidot.com/scp-914/ SCP-914]] within the first half hour of the game. [[https://scpcb.fandom.com/wiki/SCP-914/outputs Using it effectively]] can grant you unlimited sprint, the ability to see when [=SCPs=] are nearby, and an otherwise unobtainable keycard of the highest level.
* DontLookAtMe: [[https://scp-wiki.wikidot.com/scp-096/ SCP-096]] will attack and kill anyone who sees its face after a brief moment of freaking out.
* DownerEnding: [[spoiler:Of the four endings, D-9341 dies in two of them and is captured by the Foundation and classified as an SCP in the third.]]
* DreamWalker: [[https://scp-wiki.wikidot.com/scp-990/ SCP-990]] occasionally appears in the loading screens, giving you vague warnings.
* DrivenToSuicide:
** [[https://scp-wiki.wikidot.com/scp-012/ SCP-012]] will make you kill yourself trying to finish it if you remain in its presence for too long. As long as you don't walk into the room, you'll be fine.
** A panicking and sobbing guard will shoot himself in the bathroom.
** Another guard will be driven insane by his malfunctioning radio equipment in the presence of [[https://scp-wiki.wikidot.com/scp-895/ SCP-895]] and leap off the top of the stairwell to his death.
* DutchAngle: Happens in [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]]'s pocket dimension.
* EasterEgg: There are a number of joke [=SCPs=] or [=SCPs=] that don't really impact the game that you can find and interact with. They don't really affect the gameplay experience that much and mainly serve as a ContinuityNod.
* ElaborateUndergroundBase: the facility appears to be mostly underground, but it has entire containment chambers, lots of elevators, several security systems, many hallways and rooms, not to mention that it has a nuclear warhead inside one of the chambers deeper underground.
** Since the game starts deep inside the facility, there are only '''two''' times that the player can get up to the surface in the endings: Gate A and Gate B. Gate A has a skylight as well as a small bridgeway crossing over a road, and Gate B has a tunnel system as well as a little glass-covered walkway in the snow to another small building on the other side.
* EldritchLocation:
** [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]]'s PocketDimension. It is composed of endless hallways and diverging paths and the entire layout can randomly change when the player character blinks. There are also bottomless pits and floating stone structures lain about. All of this is directly controlled by [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]] himself.
** The [[https://scp-wiki.wikidot.com/scp-1499/ SCP-1499]] landscape, which can be reached by equipping [[https://scp-wiki.wikidot.com/scp-1499/ SCP-1499]], found in the Light Containment Zone. It is a dark gritty dimension with a murky grey sky, odd constructions and instances of [[HumanoidAbomination SCP-1499-1]], which will gang up on the player should they remain close to a wandering instance for too long.
** Using [[https://scp-wiki.wikidot.com/scp-860/ SCP-860]] (the blue key found in the Light Containment Zone) on the wooden doors in the Entrance Zone will take the player to SCP-860-1, a forest shrouded in blue mist with a dirt path twisting between the trees.
* ElevatorEscape: There are a handful of elevators scattered around the facility that make convenient escape routes. Of course, the lower levels have dangers of their own...
* EnemyChatter: The Nine-Tailed Fox commandos will chat with each other as they move through the facility. You can eavesdrop on them from a safe distance if you have a radio on your person.
* EnemyDetectingRadar: Putting the S-Nav through [[https://scp-wiki.wikidot.com/scp-914/ SCP-914]] on the 'Very Fine' setting allows it to track [=SCPs=] within a certain distance, but only to the extent of "it's about this close to you" without giving a bearing. The night vision goggles can also do this when upgraded on 'Very Fine', being able to detect how far certain [=SCPs=] are from you more directly, and even being able to track humans such as the Nine-Tailed Fox.
* EnemyMine: You can end up [[spoiler:making a deal with [[https://scp-wiki.wikidot.com/scp-079/ SCP-079]] so that he can open Gate B for you. Granted, exiting through Gate B always results in your death, although it's not clear whether or not [[https://scp-wiki.wikidot.com/scp-079/ SCP-079]] knew this at the time]].
* EveryoneHasStandards: D-9341, who is dumb enough to drink iron, pain, [=SCP-106=], gold, steel, [[ExactWords Joe]], carbon, lava, anti-matter, poison, venom, motor oil, and ''[[TooDumbToLive death]]'' dispensed by [[https://scp-wiki.wikidot.com/scp-294/ SCP-294]], will draw the line at drinking shit, pus, and semen.
* EvilIsNotAToy: [[spoiler:[[TheMole Dr. Maynard]] ''really'' should have known that unleashing [[HumanoidAbomination SCP-106]] wouldn't end well for him.]]
* FauxAffablyEvil: [[https://scp-wiki.wikidot.com/scp-035/ SCP-035]] will try to gain the player's trust by coaxing them to open their chamber door and release them. It will drop its act if you try to gas it to death or wait too long, telling the player that they have no chance to survive. Should you gas him then open the door, he will instead tell you that [[https://scp-wiki.wikidot.com/scp-012/ SCP-012]] [[BlatantLies is a map that you can interpret by "reading between the lines"]].
* FinalDeathMode: Keter difficulty.
* FirstDayFromHell: Judging from the "Welcome to the Foundation" note on his desk, this is D-9341's first day as a class-D. It doesn't exactly go as planned. [[spoiler:Subverted in that he was apparently a high-level Foundation scientist who was demoted and [[LaserGuidedAmnesia mind-wiped]] for conducting unauthorized research.]]
* GameBreakingBug: A few are known to exist:
** On occasion, the game can crash with the message "Memory Access Violation", meaning that an error occurred when the game was trying to load a certain sound/mesh/texture. This sort of error has a variety of causes, almost all of which boil down to programmer error.
** Also on occasion, reloading a save when you die causes you to fall through the floor of the map. To get back, you have to restart the game and then reload the save. Update logs say that the bug has been fixed, but it still happens.
** Similar to the "fall through the floor" glitch above, there is another more random glitch in which the character will fall through the floor of an elevator once activated. This is prevalent in the updates in which the game loads during elevator activation.
* GangUpOnTheHuman: The hostile [=SCPs=] don't attack each other, only the player and the MTF.
* GlowingEyesOfDoom:
** The feline-like predator inside SCP-860-1 has huge yellow eyes, which will watch you from afar as you make your way down the trail. [[IChooseToStay Izumi Junko]] seems to have them too, though she isn't hostile.
** SCP-106 has white glowing eyes as well, though they're only visible at a distance and in the dark.
* GoryDiscretionShot: During the server room event, the CruelAndUnusualDeath of a guard at the hands of SCP-096 is obscured by a blood splatter on the window.
* GreaterScopeVillain: The instigator of the containment breach, [[spoiler:the Chaos Insurgency. Its undercover agents Dr. Maynard had given [[https://scp-wiki.wikidot.com/scp-079/ SCP-079]] access to the site's major systems while Agent Skinner released [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]] as a distraction]].
* GuideDangIt: Virtually nothing is explained to you in the game outside of a few documents that explain the various [=SCP=]s and how to survive them. And the only way you can learn about how to get certain endings is by looking it up on the wiki.
* HaveANiceDeath: Every time you die, the end screen shows a [[https://scpcb.fandom.com/wiki/Death_Messages death message]] which are usually excerpts or quotes from personnel cleaning up the facility. There's a unique message for just about every possible way you can die. Talk about attention to detail.
* HeKnowsTooMuch: [[spoiler:Inverted, as this is the reason the Chaos Insurgency agents ''don't'' kill D-9341, although they still kidnap him.]]
* HellishCopter: A flight of Apaches show up in the Gate B ending, one of which is taken down by [[spoiler:[[https://scp-wiki.wikidot.com/scp-682/ SCP-682]]]]. In both that ending and the Gate A ending, they can shoot at you too, and [[spoiler:should the warheads be disabled, one will get into position so D-9341 can be shot in the other Gate B ending]].
* HellIsThatNoise:
** [[https://scp-wiki.wikidot.com/scp-049/ SCP-049]] has VaderBreath and very loud footsteps.
** [[https://scp-wiki.wikidot.com/scp-096/ SCP-096]] constantly sobs while covering its face, so you'll know roughly when to [[DontLookAtMe keep your eyes closed]].
*** Not to mention, its aggro sound is an [[https://www.youtube.com/watch?v=QBBh-b1g-3A unholy crescendo of distorted screaming]] that is terrifying on a primal level.
** [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]] has an EvilLaugh, which is often a sign that he just teleported right next to you.
** [[https://scp-wiki.wikidot.com/scp-173/ SCP-173]], being made of concrete, makes a scraping sound as it moves around the facility.
** [[https://scp-wiki.wikidot.com/scp-939/ SCP-939]] have light, clinking footsteps and can mimic voices.
** [[https://scp-wiki.wikidot.com/scp-966/ SCP-966]] make a distinctive breathing/hissing sound as they drain your stamina.
** The Nine-Tailed Fox commandos can be identified by their radio chatter and clunky footsteps.
* HoistByHisOwnPetard: [[spoiler:[[TheMole Dr. Maynard]] released [[HumanoidAbomination SCP-106]]... and was promptly abducted and killed by it.]]
* HopeSpot:
** If you don't [[spoiler:contain [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]]]] before heading to Gate A, then [[spoiler:the personnel stationed there will be focused on 106 rather then the player. The player can take this opportunity to escape through one of the service tunnels... only to be stopped by the Chaos Insurgency, who warp the player away, believing that D-9341 knows too much to be killed]].
** Disabling the Alpha warheads before going through Gate B leads to the detonation being cancelled, making it seem like you have a real chance of getting out alive... [[spoiler:until you are cornered by MTF units and get shot to death]].
** While in [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]]'s pocket dimension, there's a chance that you will warp into a room which resembles a hallway from the site. This is merely a fake, as leaving this hall sends you back into the dimension's main rooms.
* IAmTheNoun: One of SCP-049's phrases: "I am the cure." The cure to what? Only he knows.
* IChooseToStay: Agent Izumi Junko was sent into SCP-860-1 to explore, but like [[https://scp-wiki.wikidot.com/document-860-i-and-ii D-5674]], she was apparently welcomed by the forest and decided to abandon her mission. Her silhouette can occasionally be seen peering at the player from behind the trees.
* DarthWiki/IdiotDesign[[invoked]]: InUniverse. The T-shaped hallways were apparently supposed to halt SCP-173 from getting further into the facility in the event of a containment breach. However, due to a man-sized ventilation duct going into the hallways, this does nothing to impede SCP-173's rampage.
** Seeing as several high-level members of the site were Chaos Insurgents, it is possible the designer of the area was one and designed it to cause chaos in the event of a breach.
* ImmuneToBullets: SCP-173 and SCP-096 get sprayed by machine gun fire on separate occasions and don't have a scratch to show for it afterward.
* ImplacableMan: [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]], and to a lesser extent [[https://scp-wiki.wikidot.com/scp-049/ SCP-049]]. Both will both relentlessly pursue the player at a walking pace, regardless of how many doors you close behind you (106 can teleport through walls, and 049 can open doors even without a keycard).
* InsideJob: [[spoiler:Dr. Maynard and Agent Skinner were plants by the Chaos Insurgency. Dr. Maynard used his position as a top level researcher to create and implement the "Modular Site Project", having several dangerous (and many useful) SCP moved into a maze-like facility that would confuse anyone who didn't have the clearance to get the specific floor plan of the facility. Agent Skinner was assigned as part of a 2 man team to guard [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]]'s containment chamber (presumably on the orders of Dr. Maynard). Once everything was ready, Agent Skinner waited until his Foundation assigned partner was distracted, before releasing [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]]. While the rest of the Foundation staff was preoccupied by recontaining [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]], Dr. Maynard entered [[https://scp-wiki.wikidot.com/scp-079/ SCP-079]]'s containment chamber, hooked it up to the facility's network, and reminded it that the Foundation was responsible for its imprisonment. Using its new access, [[https://scp-wiki.wikidot.com/scp-079/ SCP-079]] caused several containment breaches throughout the facility by remotely shutting down several critical security measures (such as locking the blast doors to [[https://scp-wiki.wikidot.com/scp-173/ SCP-173]]'s chamber open).]]
* InterfaceScrew:
** The screen often blurs slightly in the presense of a hostile SCP, and [[HumanoidAbomination SCP-106]] in particular will produce a VertigoEffect if you meet his gaze. His PocketDimension is also very disorienting, and it takes several seconds for D-9341's eyes to adjust to it.
** Putting yourself through [[https://scp-wiki.wikidot.com/scp-914/ SCP-914]] on the '1:1' setting will invert your controls.
* InvisibleMonsters: [[https://scp-wiki.wikidot.com/scp-966 SCP-966]] are only visible if you're wearing night vision goggles. You can still hear their footsteps, though, and if a door opens on its own you can bet one is nearby.
* InvincibleBoogeymen:
** SCP-173, which CantMoveWhileBeingWatched. Your only defense is to keep looking at it, to run away, or to close doors to delay its advance.
** SCP-096, who will kill you if you look at it. The only way to survive it is avoid eye contact with its face at all times. The second you look at it, you're dead.
** SCP-106, an EldritchAbomination with phasing powers who loves to hunt its prey for amusement. You must always avoid letting him see you, otherwise he'll pursue you until he catches you. Unlike the other two examples, he can be deterred and recaptured, but it's very difficult to do so.
* ItCanThink: SCP-966, while non-sapient, are smart enough to open doors while pursuing the player.
* JumpScare: Countless:
** Invoked with [[https://scp-wiki.wikidot.com/scp-372/ SCP-372]], which can only be seen in your peripheral vision. 372 is harmless, but its entire purpose is to occasionally fly across the screen to freak the player out. 372 can be avoided entirely by simply not entering its containment chamber.
** The game plays a loud ScareChord whenever [[https://scp-wiki.wikidot.com/scp-173/ SCP-173]] suddenly appears close to you.
** Occasionally [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]]'s face will flash in front of you while you're in the PocketDimension.
** [[https://scp-wiki.wikidot.com/scp-895/ SCP-895's]] [[SchmuckBait monitor will display shock images]] [[TooDumbToLive if you stare at it too long.]] And thanks to [[https://scp-wiki.wikidot.com/scp-079/ SCP-079]], it can randomly happen on any of the [=CCTVs=] throughout the facility.
* KneelBeforeZod: If the player ends up in [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]]'s throne room in the PocketDimension, 106 will eventually order them to kneel in a [[EvilSoundsDeep hauntingly deep]] [[VoiceOfTheLegion and echoing]] voice.
* {{Leitmotif}}:
** When [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]] is chasing the player, [[https://www.youtube.com/watch?v=PH2FhZZscrQ this]] plays.
** [[https://scp-wiki.wikidot.com/scp-096/ SCP-096]] has one consisting entirely of {{Scare Chord}}s.
** [[https://scp-wiki.wikidot.com/scp-049/ SCP-049]]'s leitmotif is an ominous drone that promises disease and death to anyone close to hear it, as befitting a PlagueDoctor.
* LightsOffSomebodyDies: During the intro sequence, the lights begin to flicker, allowing [[https://scp-wiki.wikidot.com/scp-173/ SCP-173]] to kill two D-Class personnel ([[BornLucky but not you]]) along with a guard before going into the ventilation system.
* TheLostWoods: [[https://scp-wiki.wikidot.com/scp-860/ SCP-860]] lets you gain access to SCP-860-1, a small forest shrouded in blue mist. The only way to get through it is by reaching the end of the pathway, which is made difficult by the feline-like creature which stalks the trees and will attack you.
* LuckBasedMission:
** Due to [[https://scp-wiki.wikidot.com/scp-173/ SCP-173]] having a glitchy pathfinding system, it can occasionally snap the player's neck from out of nowhere. As of recent versions, this has been happening more frequently.
** Previously played straight with room generation, too. It was entirely possible to go for over an hour without finding a single keycard... or you could find all of the essential items within ten minutes and then encounter [[https://scp-wiki.wikidot.com/scp-914/ SCP-914]] just a stone's throw away from the starting point. Newer versions have mostly corrected this.
** How well your game goes will depend a lot on how quickly you can find [[https://scp-wiki.wikidot.com/scp-914/ SCP-914]], though less so in more recent versions where you can only make up to a level 3 keycard with it unless you already got the level 4 keycard from 049's chamber, where you can make up to Omni keycards.
** Due to the Mobile Task Force having an incredibly buggy AI, they can often get stuck in doors, making it impossible to get around them without the use of [[MasterConsole console commands]].
* MalevolentArchitecture: The Heavy Containment zone is dedicated to containing [=SCPs=] which are both dangerous and difficult to contain. This sure seems like the most optimal place to store a warhead, doesn't it?
* MaybeMagicMaybeMundane: The "Smelly Joint" produced by running [[https://scp-wiki.wikidot.com/scp-420-J/ SCP-420-J]] through [[https://scp-wiki.wikidot.com/scp-914/ SCP-914]] causes D-9314 to "take a nap" and die. It might be the effects of the joint itself... or it could just be that you took a nap ''[[TooDumbToLive in the middle of a containment breach]]''.
* MissedHimByThatMuch: [[https://scp-wiki.wikidot.com/scp-682/ SCP-682]]'s breakout at Gate B occurs mere ''seconds'' after you leave the area.
* MultipleEndings: There are currently four, which depend on your choices made in the game and which exit you choose, [[spoiler:though all of them end with D-9341 either [[DownerEnding not making it out alive]] or [[BittersweetEnding getting kidnapped]]]]. More may be added later, but currently your choices are:
** [[spoiler:You get out of the facility through Gate B and [[HopeSpot it seems that you're home-free...]] except that the alarms start blaring and the facility intercom shouts that [[https://scp-wiki.wikidot.com/scp-682/ SCP-682]] [[OhCrap has just escaped]] and tells everybody to evacuate before the on-site nuke is used to blast 682. The blast goes off and you die. The end screen shows a radio conversation between two personnel, with one of them requesting the deployment of an MTF unit to scout for remains at ground zero. However, the transmission is cut-off mid sentence as a large roar is heard, indicating that the nuclear blast was not successful in destroying [[https://scp-wiki.wikidot.com/scp-682/ SCP-682]].]]
** [[spoiler:If you disarm the nuke before going out through Gate B, then it fails to detonate. However, you still don't escape because you are gunned down in the middle of the fight with [[https://scp-wiki.wikidot.com/scp-682/ SCP-682]].]]
** [[spoiler:You get out through Gate A only to come to a bridge with Foundation task forces on the other side, blocking your escape. Suddenly, [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]] will attempt to escape through Gate A. The Foundation will then use a High Intensity Discharge (H.I.D.) Turret to force it to retreat back into its pocket dimension. You then use this opportunity to escape through the service tunnel, only to be stopped by the Chaos Insurgency. They state that you know too much to be killed, and proceed to warp you away.]]
** [[spoiler:If you contain [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]] and then get out though Gate A, the guards will capture you. The end screen will play a excerpt from a testing log talking about D-9341's [[BornLucky extraordinary luck, ability to predict the unpredictable, and his ability to survive even the most fatal scenarios against all odds]]. It also mentions the possibility of [[FateWorseThanDeath classifying him as a SCP]]. [[BreakingTheFourthWall This ending is referencing the fact that the player can reset the game from the last save point if they die, effectively allowing them to avoid all hazards.]]]]
* NeckSnap: [[https://scp-wiki.wikidot.com/scp-173/ SCP-173]]'s trademark.
* NoSell: [[https://scp-wiki.wikidot.com/scp-714/ SCP-714]] protects the player against a few of the dangers that would kill the player, mainly [[https://scp-wiki.wikidot.com/scp-049/ SCP-049]]'s lethal touch, diseases from [[https://scp-wiki.wikidot.com/scp-1025/ SCP-1025]], and [[https://scp-wiki.wikidot.com/scp-012/ SCP-012]]'s mental influence. [[spoiler:It also nullifies [[https://scp-wiki.wikidot.com/scp-420-J/ SCP-420-J]].]]
* NothingIsScarier: The player can come across [[https://scp-wiki.wikidot.com/scp-1048/ SCP-1048]] standing around or dancing in the Heavy Containment Zone, and it won't be there again if they leave the area and then come back. [[spoiler:Those familiar with the wiki will know that plenty of people have died thanks to [[https://scp-wiki.wikidot.com/scp-1048/ SCP-1048]] wandering the facility unchecked, but currently, its presence in the game is harmless to the player, and its appearance is ostensibly meant only to be ParanoiaFuel.]]
** After updates, it's more ZigzaggedTrope. [[spoiler:1048 is still harmless... but [[BodyHorror 1048-A]] is present, and it most definitely ''isn't''. [[CruelAndUnusualDeath You]] ''[[CruelAndUnusualDeath really]]'' [[CruelAndUnusualDeath don't want to get too close to it.]]]]
* NukeEm:
** The fallback plan if [[https://scp-wiki.wikidot.com/scp-682/ SCP-682]] escapes. [[spoiler:It doesn't work. You can shut this off if you find the warhead control room.]]
** You can do this yourself if you [[TooDumbToLive order yourself a nice cup of nuclear explosion]] at [[https://scp-wiki.wikidot.com/scp-294/ SCP-294]]. You can also ramp it up to a cup of antimatter if you really wish to make a crater the size of Oregon when you die.
* OffscreenTeleportation: [[https://scp-wiki.wikidot.com/scp-173/ SCP-173]] is said to be using the ventilation system to travel around the facility, when in reality it's just pre-set to spawn in certain rooms. [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]] takes this further, being able to appear out of nowhere and being incorporeal. SCP-049 also sometimes does this without any real explanation when the player evades him and there needs to be a way to show how he can get past being sealed away by a keycard or passcode lock or even a checkpoint. Same with the instances of SCP-966, which are often respawned around the facility in much the same manner as 049.
* OminousWalk: [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]] pursues the player at a walking pace, teleporting through walls to keep you from getting too far ahead. [[https://scp-wiki.wikidot.com/scp-966/ SCP-966]] do this as well, thankfully minus the teleporting.
* OneSizeFitsAll: [[https://scp-wiki.wikidot.com/scp-714/ SCP-714]] fits itself to the wearer's finger.
* PerpetualMotionMachine: Running the radio and S-Nav device through [[https://scp-wiki.wikidot.com/scp-914/ SCP-914]] can take away the need to power them with batteries.
* PlagueZombie:
** [[https://scp-wiki.wikidot.com/scp-008/ SCP-008]] will eventually turn the player into one if they get exposed to it, causing a NonStandardGameOver. You can cure it with [[https://scp-wiki.wikidot.com/scp-500/ SCP-500]].
** Played very straight with [[https://scp-wiki.wikidot.com/scp-049/ SCP-049-2]], the Plague Doctor's zombies.
* PragmaticAdaptation: Many items, such as [[https://scp-wiki.wikidot.com/scp-513/ SCP-513]], canonically take hours to begin having an effect once activated, but in the game this is reduced to minutes or even seconds for more immediate results.
* PressXToDie: The game offers a '''lot''' of opportunities for the player to kill himself with minimal effort. [[AllThereInTheManual Knowing about the SCPs you encounter before approaching them]] can help a lot, at which point dying in most of these ways is [[YetAnotherStupidDeath your own fault.]]
** [[https://scp-wiki.wikidot.com/scp-294/ SCP-294]] probably has the most of these; there's nothing stopping you from [[TooDumbToLive ordering a nice cup of lava or carbon]], or even [[NukeEm nuclear fission or antimatter.]] Or you can do it the boring way and simply order a cup of GameOver.
* PublicDomainSoundtrack: At least half of the game's soundtrack is composed by Music/KevinMacLeod and royalty-free.
* RandomlyGeneratedLevels: The game is separated into 3 zones, with each one having specific rooms spawn in them.
* RedShirt: The PlayerCharacter is D-9341, one of the Foundation's expendable guinea pigs. Two fellow D-class are killed in the opening sequence, and another dead one can be found in the Heavy Containment Zone. The player may also encounter guards who fall prey to the hostile [=SCP=]s, such as the unlucky bastard who sees [[https://scp-wiki.wikidot.com/scp-096/ SCP-096]]'s face in the server room and gets [[CruelAndUnusualDeath [DATA EXPUNGED]]] by it.
* SaveScumming / MentalTimeTravel: Lampshaded in one of the endings.
* ScareChord:
** Whenever SCP-173 changes locations near you.
** SCP-096's {{Leitmotif}} consists entirely of these, making it very easy to tell when he's nearby. Another, more specific, chord plays if you [[YouAreAlreadyDead see his face]].
* ScenicTourLevel: During the intro sequence, the tunnel and catwalk bridge are fully-lit, with no gas shooting into your eyeballs (which is nice).
* SchmuckBait:
** SCP cells are often blocked by little more than a keycard. As long as you have that, there's nothing stopping you from walking in and getting yourself killed by whatever horror it contains.
** If you try to kill [[https://scp-wiki.wikidot.com/scp-035/ SCP-035]] with gas, he'll tell you to find [[https://scp-wiki.wikidot.com/scp-012/ SCP-012]] and "read between the lines".
* ScrewThisImOuttaHere: The Nine-Tailed Fox commandos will run like hell if they encounter [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]].
* SensoryAbuse: [[https://scp-wiki.wikidot.com/scp-066/ SCP-066]] can randomly blast loud Beethoven music. Keep your volume down around it.
* ShoutOut:
** The map seeds are usually random letters and numbers, but you might occasionally get something like "rustledjim" ("Rustled jimmies").
** D-9341 can order a microwave casserole from [[https://scp-wiki.wikidot.com/scp-294/ SCP-294]], [[VideoGame/HalfLife but he feels like it belongs to someone else and doesn't drink it.]]
*** Another Valve ShoutOut comes in the form of an alternate keyword for getting a cup of urine: "[[VideoGame/TeamFortress2 Jarate]]".
*** You can also order a cup of [[Memes/ValveSoftware Half-Life 3]]... but you'll get an empty cup.
** Also on [[https://scp-wiki.wikidot.com/scp-294/ SCP-294]], you can use [[WesternAnimation/MyLittlePonyFriendshipIsMagic "Pinkie Pie's Greatest Ability"]] as another word of "Fourth Wall" [[DontExplainTheJoke because Pinkie Pie often breaks the fourth wall.]] However this has been removed from later versions of the game likely due to legal reasons.
** If you drink a cup of [[VideoGame/AmnesiaTheDarkDescent Amnesia]], which is the name of another horror game, a quote from that game will appear on screen and blurs your vision.
*** You can also order an Aqua Regia.
** Ordering a cup of [[Franchise/TheElderScrolls CHIM]] grants you GodMode.
** Ordering a cup of element 0, element Zero, neutronium, neutrium, or tetraneutron nets you this line before killing you:
--->[[Franchise/MassEffect "You didn't think Biotic Powers were real? Right?"]]
* SprintMeter: There's a meter for sprinting and one for ''blinking'', preventing you from staring at [[https://scp-wiki.wikidot.com/scp-173/ SCP-173]] forever.
* SuddenlyVoiced: D-9341 can be heard speaking when under the influence of [[https://scp-wiki.wikidot.com/scp-012/ SCP-012]]. SCP-106 may also command the player to KneelBeforeZod in his pocket dimension.
* SurprisinglyRealisticOutcome: The player can find a syringe which gives them an adrenaline boost. Even as small as a point can be, the syringe can still pierce the skin well. But because they don't have anything to bandage the entry point of the syringe with, they begin to bleed from using it due to the entry point in the skin still being open from being pierced.
* TakeThat: Various drinks from [[https://scp-wiki.wikidot.com/scp-294/ SCP-294]] provide these:
** If you order [[VideoGame/HalfLife Half Life 3]], you get [[{{Vaporware}} an empty cup.]]
** A cupful of [[Website/FourChan 4chan]] is described as tasting "awfully bitter".
** Ordering 9GAG will produce a cup of semen.
** Older versions of the game (now removed, likely due to legal reasons) allowed you to order a cup of ''VideoGame/CallOfDuty'', and drinking it would produce the message: ''"The drink tastes like dubstep and ur mom."''
* TerrifyingRescuer: Oh thank god, they're sending in a mobile task force to secure the facility... Wait, why are they pointing guns at me? What do you mean, "[[OhCrap D-9431 designated for termination]]"!?!
* TheComputerIsACheatingBastard: [[https://scp-wiki.wikidot.com/scp-173/ SCP-173]] can often clip through walls, leading to many points where it can kill you from out of nowhere. The bug has been said to have been fixed in 6 different versions of the game, but it still exists in the current version as of now.
* TheManyDeathsOfYou: A lot, all of which come with an after-action report of Foundation personnel finding evidence of your demise after they re-take the site:
** Getting zapped by a Tesla gate.
** Putting yourself through 914 on Rough, Coarse, Fine or Very Fine.
** Falling into the void in the Pocket Dimension.
** Looking at [[https://scp-wiki.wikidot.com/scp-096/ SCP-096]], then being [DATA EXPUNGED] by it.
** Walking up to [[https://scp-wiki.wikidot.com/scp-008/ SCP-008]]'s canister and getting turned into a zombie.
** Going into [[https://scp-wiki.wikidot.com/scp-012/ SCP-012]], [[https://scp-wiki.wikidot.com/scp-035/ 035]], or [[https://scp-wiki.wikidot.com/scp-895/ 895]]'s chambers.
** Reading [[https://scp-wiki.wikidot.com/scp-1025/ SCP-1025]], specifically the entry on "Cardiac Arrest".
** Getting abducted by [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]], whisked away to his PocketDimension, and [[AndIMustScream slowly tortured to death]]. Bonus points if this happens because you began his recall protocol without having first deactivated the ELO-IID magnetics.
** Getting "[[TouchOfDeath cured]]" by [[https://scp-wiki.wikidot.com/scp-049/ SCP-049]].
** Getting your neck snapped by [[https://scp-wiki.wikidot.com/scp-173/ SCP-173]].
** [[DrugsAreBad Smoking a joint]] courtesy of [[https://scp-wiki.wikidot.com/scp-914/ SCP-914]].
** Touching a strange battery.
** Ordering an explosive or any other drink that can kill you from [[https://scp-wiki.wikidot.com/scp-294/ SCP-294]].
** Getting shot by an MTF unit.
** Getting EatenAlive by [[https://scp-wiki.wikidot.com/scp-939/ SCP-939]].
** Getting mauled by the AnimalisticAbomination in [[https://scp-wiki.wikidot.com/scp-860/ SCP-860]].
** Getting a lung ripped out of your chest if you do not have any items when interacting with [[https://scp-wiki.wikidot.com/scp-1162/ SCP-1162]].
** Getting "optimized" into a [[BodyHorror Flesh Beast]] by [[https://scp-wiki.wikidot.com/scp-427/ SCP-427]]
* ToiletHumour: Occasionally you may hear [[https://scp-wiki.wikidot.com/scp-789-J/ SCP-789-J]] when you're in the bathroom.
-->'''SCP-789-J:''' I AM THE BUTT GHOST, I WILL EAT YOUR BUTT.
* TooAwesomeToUse: [[https://scp-wiki.wikidot.com/scp-500/ SCP-500]] pills can heal all of your illnesses. However, they are very scarce, as there are only up to two scattered around the facility.
* TouchOfDeath: [[https://scp-wiki.wikidot.com/scp-049/ SCP-049]]'s method of attack.
* TrappedWithMonsterPlot:
** The basic premise. A ''lot'' of monsters breach containment at once, and you have to find your way out of the facility while keeping them from eating your face.
** [[https://scp-wiki.wikidot.com/scp-049/ SCP-049]]'s chamber. As soon as you get there the elevator breaks down, forcing you to dodge zombies (and eventually the PlagueDoctor himself) as you try to get it working again.
* TheUnfought: [[https://scp-wiki.wikidot.com/scp-682/ SCP-682]] can be heard roaring from time to time, and you can briefly explore its containment chamber, but the big lizard itself never appears in the flesh. The closest you come to encountering it is [[spoiler:during the Gate B ending, where you can see three Apaches engaging it in the distance]].
* UnwinnableByDesign: Looking at [[https://scp-wiki.wikidot.com/scp-096/ SCP-096's]] face [[DontLookAtMe will make him kill you]] and [[TheJuggernaut there's nothing you can do to stop him, kill him, or escape him]].
* VaderBreath: [[https://scp-wiki.wikidot.com/scp-049/ SCP-049]] does this, making it easy to tell if he's nearby.
* VideoGameCrueltyPotential: You can trap [[https://scp-wiki.wikidot.com/scp-106/ SCP-106]] in his cage, thus eliminating one of the big threats that will harass you throughout the game. The only downside? To do it, you have to break a man's femur in order to lure 106 into the cage and trap him. Not only do you injure the man to make him scream, but by locking him in with 106, you definitely sentenced him to a horribly painful demise.
* VillainProtagonist: Revealed [[spoiler:through the [[https://scp-wiki.wikidot.com/scp-1162/ SCP-1162]] event that D-9341 was a Researcher before unauthorised research had him demoted to a Class-D]].
* VillainousFriendship: [[AIIsACrapshoot SCP-079]] and [[GodzillaThreshold SCP-682]] have this in the game, as mentioned in their documents. If the player goes down to where 682's document is found, 079 activates valves of decontamination gas and tells them "You're not getting out" to try to keep them from leaving with 682's document.
* VoiceChangeling: [[https://scp-wiki.wikidot.com/scp-939/ SCP-939]], appropriately named "Of Many Voices". In game, it speaks in the voices of various Foundation personnel in order to draw the player closer to it's location. [[spoiler: It's actually a spiky carnivorous monster that will attack you and try to devour you. The voices are bait, taken from its previous victims.]]
* WhiteMaskOfDoom: [[https://scp-wiki.wikidot.com/scp-035/ SCP-035]] can be found in its chamber, possessing a scientist.
* TheWorfEffect: [[https://scp-wiki.wikidot.com/scp-173/ SCP-173]] is arguably the main antagonist of the game. [[spoiler:If Nine-Tailed Fox finds it, they can actually contain it and return it to its cell]]!
* YouWakeUpInARoom: The game starts in your cell, from which you are removed for an experiment with [[https://scp-wiki.wikidot.com/scp-173/ SCP-173]]. There's also a document explaining your purpose at the facility.
* YetAnotherStupidDeath: There are many, ''many'' anomalies and security systems waiting to kill you, and many of them are perfectly avoidable. You don't have any real reason to [[BrownNote stare at SCP-895's video feed long enough for its effect to take place]], or to request an obviously dangerous drink from [[VengefulVendingMachine SCP-294]], but then again, it's often [[SchmuckBait too tempting not to]].

!!''SCP: Unity'' contains examples of:
* BigBad: SCP-106 has been confirmed to be this, since he can go anywhere, while SCP-173, the most common enemy in the original version, is only in the Light Containment Zone in the remake.
* ABirthdayNotABreak: As if dealing with the containment breach on ''any'' day wasn't bad enough, it happened on the player character's birthday in the Unity remake, as indicated by [[https://scp-wiki.wikidot.com/scp-983/ SCP-983]] (the Birthday Monkey) activating to sing its birthday song, which only [[DiedOnTheirBirthday kills targeted individuals on their birthdays]].
* HappyPlace: Between the sight of peaceful origami dragons gliding through the air and the tranquil music that plays, players will likely consider SCP-1762's containment area this. Of course, it only becomes that way if you are able to use SCP-914 to produce a canister of argon, let alone find SCP-1762's room after to insert it and unlock the cell.
* JumpScare: [[https://scp-wiki.wikidot.com/scp-650/ SCP-650]]. It will not harm you, but it will always appear right next or behind you in the worst possible moments, freakishly hunching over you as if attempting to attack you.
* TheManyDeathsOfYou: The Unity version adds getting your hands chopped off from taking a third piece from [[https://scp-wiki.wikidot.com/scp-330/ SCP-330]] and interacting with the beings that only seen with [[https://scp-wiki.wikidot.com/scp-178/ SCP-178]].
* ShmuckBait: [[https://scp-wiki.wikidot.com/scp-330/ SCP-330]]. It clearly tells you not to take more than two pieces of candy from it. [[spoiler: Say goodbye to your hands if you try to take three.]]
