History VideoGame / SCPSecretLaboratory

* ElevatorActionSequence: More common than you think in the elevators to Surface/Heavy Containment/the Nuke Silo/SCP-049 and 173's containment. Although it's usually done by the SCPs

** Foundation weapons clearly are based off of NATO firearms, with Facility Guards getting an SMG based off of the MP7, MTF Privates also get an SMG, this time based off of the KRISS Vector. Sergeants get MTF-E11-SRs, which are based off of the Maxim Defense MDX series of AR-15 rifles, and the Captains, they get the almighty FR-MG-0, which is just plainly a H&K G36. Hell, the COM-18 used to be based off of the H&K USP.
** Chaos Insurgents also irregular patterns. The AKs of their Riflemen and Conscripts are a Mishmash of various real-world AKs, Marauders get a S&W Model 500 chambered in .44 Magnum, and carry a DP-12, and the Repressors get Logicers, which are based off of the H&K MG5.

* HellIsThatNoise: Your survival as a human depends on listening for the noises that your enemies make. Hearing footsteps as a scientist can easily make you paranoid in wondering if MTF has come to rescue you, or if it's SCP-939 patrolling the only path to freedom. On the SCP side of things, hearing the sounds of 173's stone body sliding against the floor, 096's constant sobbing and screaming, and 049's slow but sharp foot steps closing in on you is bound to get some people anxious. [[NightmareRetardant On a less (or more) horrific note]], there's the sound of some asshole (read: nearly everyone who gets the chance) playing [[SensoryAbuse extremely loud music over the facility intercom and blowing out the eardrums of the entire server.]]

** Chaos Insurgency players come armed with [=AKs=], Shotguns, and Light Machine Guns that can tear down anyone within their effective range very easily. This comes at the cost of being poor for mid-long range engagements thanks to their heavy recoil and low bullet accuracy

* StoneWall: SCP-106 isn't as instantly lethal as other [=SCPs=] and moves at a steady striding pace, but he has an obscenely high amount of health that soon teaches players that when facing 106, your best bet is to just run unless you think he's wounded enough to be put him down with conventional firearms.

* GuideDangIt: [[SubvertedTrope Subverted]]. Before the Refracted Reality update added a guide that detailed everything in the game to the main menu, all that was covered was the concept behind keycards and how to use SCP-914, so players used to rely only on their own experience with the anomaly or the wiki.

** Instances of SCP-939 often come in pairs, so expect to see two reptiles from the same pack fighting alongside each other.
*** Averted as of the Mimicry update. Now only one 939 can spawn per round.

** In the document, SCP-939 is described as only being able to mimic the sounds made by the last prey they consumed, and even then it's mostly restricted to sounds of distress and screaming that they might've made in their final moments of their lives. In game, the pack hunters can speak with the knowledge of an entire dictionary if the player controlling them knows that much.
*** Averted after the Mimicry update, where SCP-939 can now replay the last four seconds of what their victims said into their mic.

* GuideDangIt: In terms of a tutorial, all that is covered is the concept behind keycards and how to use SCP-914. Like [[VideoGame/SCPContainmentBreach Containment Breach]], knowing what the various anomalies actually do either comes through already having read the relevant documents on the SCP Foundation website or through experience.
** Averted as of the Refracted Reality update, which added a guide with information on not only what the SCPs can do, but also [[ChekhovsGun what SCP objects the humans *could* have up their sleeves at any given time]]

* HeroicSacrifice: In the name of stopping 106, anyone can volunteer to sacrifice themselves to the femur breaker and exchange their own life to end 106. [[VideoGameCrueltyPotential Assuming you don't just trick a newbie into stepping into the]] [[ShmuckBait weird looking tube...]]
** Averted as of Mimicry, since the femur breaker's been sealed up now.

* LightningBruiser: SCP-939 by default is just barely fast enough to catch up to humans who are sprinting and deals a high amount of damage that can 2-hit kill a fully healed player.

** The COM-45. For more info, see [[LethalJokeItem Lethal Joke Item]] above.

* MoreDakka: Chaos Insurgency players come armed with [=AKs=], Shotguns, and Light Machine Guns that can tear down anyone within their effective range very easily. This comes at the cost of being poor for mid-long range engagements thanks to their heavy recoil and low bullet accuracy

* LuckBasedMission: What surviving 106'a Pocket Dimension amounts to. There's just no telling which path is the correct one, as they're all identical and randomized each time someone dies (or escapes) in the pocket dimension.

* TooAwesomeToUse: The Micro H.I.D is extremely powerful and can quickly kill anything in its path, even SCP-106, in a few seconds. But there's only one found naturally on the map, it requires 6 seconds to charge, its energy blast is just as blinding to the operator as it is to the victim, has a relatively short range, and can only be recharged at SCP-914 (whose access will be barred in the middle of the game from an automatic lockdown). While, in theory, it can kill any SCP with a full charge, in practice its only real use is either decimating SCP-096 and SCP-106, who are the most vulnerable to this beam and cannot easily outrun the user or, as a scientist or a D-Class, scaring away any SCP camping the escape path.

* SpeedrunReward: Escaping the facility in under 3 minutes earns you the {{achievement|system}} "Escape Artist".

* '''[[http://www.scp-wiki.net/scp-096 SCP-096]] / "The Shy Guy":''' A naked, hobbling, pale and lanky humanoid creature that constantly weeps to itself, the Shy Guy is completely helpless to attacks up until its shot, or its face is viewed. This will cause it to enter a rage state as it gains a tremendous amount of speed and an instant kill attack. When the Shy Guy is enraged, it will stand up while clutching its face and begin screaming and wailing loudly, warning everyone near it of what's to come. While enraged, the Shy Guy is faster than every other character in the game and is capable of [[BarrierBustingBlow tearing all doors short of an elevator down.]] After about 15 - 30 seconds (depending on how many viewed it), the Shy Guy will calm down again and won't be able to become enraged again for a while.
