Operational Guides[edit]

Class Operational Guide[edit]

A mere concrete sculpture upon first glance; an art piece to be seen and admired. 


On second glance, you’ll notice it’s somehow closer, as if yearning for attention.

There is no third glance. You’re dead by then.

___
“SCP-173 wasn’t the most peculiar anomaly in our containment. A sculpture capable of moving at high speeds when unseen. It attacks by breaking its victim’s neck. After its ‘mutation’, for lack of a better term, research and testing have resumed. Did the mutation make it our most peculiar anomaly? No, I doubt it did.”
-Dr. Simon Wolffe, SCP-173 Research Supervisor, Site-02

Abilities Operational Guides[edit]


- [M1] — Snap

While unobserved, press the Attack button to perform Snap on a human, killing them immediately. 

___
SCP-173 has been seen attacking subjects from behind. It attacks by snapping the neck at the base of the skull. The attack is carried out at a high speed, resulting in a severe and unnatural rotation of the spine; this is a minimum of 180 degrees.

- [M2] — Blink

Trigger Blink to catch your observers by surprise and rapidly attack the closest player. Press and hold Blink to have a marker of SCP-173 appear where you are facing. After releasing Blink, SCP-173 will rapidly move towards the marker’s last location, killing the nearest human in range. 

___
SCP-173 has been observed to attack subjects as far as 15 meters away in the span of a second.

- [Shift] — Breakneck Speeds

Activate Breakneck Speeds to greatly increase your movement speed; however, for as long as it is active, you will not be able to attack (though Tantrum may still be used). If a human observes you while Breakneck Speeds is active, you will lose your speed bonus rapidly. Alternatively, you can cancel Breakneck Speeds at any time by pressing the shift key.

___
After being transferred to Site-02, SCP-173 seems to have gained a new behavior. When unobserved, SCP-173 has been heard scraping and moving much faster than usual… …Interestingly, this has shown to negate its lethality.

- [F] — Tantrum

Activate Tantrum and cause SCP-173 to excrete a pool of filth on the ground. Humans caught in the pool will be unable to sprint, and gain the Stained status effect, which lasts for a short duration after the player leaves the pool. If SCP-173 kills someone while the player is under the effect, SCP-173 will instantly gain back a portion of its Hume Shield.

SCP-173 can only create a limited number of pools at a time. Creating more will result in the oldest dissipating.

___
SCP-173 has been known to cover its containment chamber in a caustic, sticky substance made of several distinct bodily fluids and [REDACTED]. The material has an orange, reddish colouration. Bubbles can be seen on the surface due to the presence of bodily fluids.

In Game[edit]

At the start of a round, SCP-173 will spawn in its Containment Cell in Light Containment Zone.
Upon spawning, SCP-173 won't be able to exit the cell right away, as the only exit (a gate) is locked shut, which gives the Class-Ds and Scientists some time to explore. After a short amount of time, the gate will automatically open, and SCP-173 can leave its cell, free to roam around the map. If SCP-173 takes no damage for 10 seconds, its Hume Shield will slowly regenerate by 20 HS/s. SCP-173 can talk to the other SCPs by holding down the Q key. This voice chat can be heard by all SCPs no matter the distance.

Hume Shield[edit]

  • SCP-173 has base Hume Shield value of 750.
  • If SCP-173 takes no damage for 10 seconds, its Hume Shield will slowly regenerate by 20 HS/s.
  • SCP-173 restores 100 Hume Shield if they kill a player under the Tantrum Effect.
  • Hume Shield does not factor in SCP-173's damage resistance.

Abilities[edit]

Neck Snap[edit]

When SCP-173 isn't being observed, they can press Left Click.png Left Click to snap a player's neck, instantly killing them. This attack will play a fairly audible sound effect, that can alert other players.

Reinforced Concrete[edit]

SCP-173 takes reduced damage from all firearms besides the Micro H.I.D. and the 3-X Particle Disruptor. This only applies to SCP-173's base HP and not their Hume Shield. This passive armor has a value of 80%, and will factor in a weapons penetration. Meaning it works the same as the Armor item. x = a(100% − p), where a is the armor protection level, p is the penetration amount of a weapon, with x being the actual damage reduced. So a weapon with 50% penetration shooting a player in the body would only reduce the damage by 40% instead of 80%.

Tantrum[edit]

SCP-173 can leave a pool of filth on the ground by pressing the F key. While multiple pools can be placed at once, the ability has a 30 second cooldown. A pool of filth will last only 180 seconds on the ground, though Tesla Gates will instantly destroy them, preventing SCP-173 from placing them near the Tesla Gate.
Players entering the pool gain the Stained Reduces player speed by 20%
Players cannot sprint
Status Effect, which lasts until the player leaves the pool plus three seconds afterwards. If SCP-173 kills a player while they are under the Stained Effect, they will instantly gain back 100 Hume Shield.

Blink[edit]

When SCP-173 is being looked at by a Human, SCP-173 will stop moving and be locked in place. A small HUD element will appear on SCP-173's screen displaying a 3.6 second countdown for their Blink ability. When the cooldown ends, the player can hold Right Click.png Right Click make a marker appear on the ground. The marker can be moved by using the mouse. When the player releases Right Click.png Right Click, SCP-173 will teleport to their mark, which will force humans to blink. If any humans are in range, SCP-173 will automatically kill the closest one. The marker will change colors to display if SCP-173 is within killing range of a human or if Breakneck Speeds is activated.
The Blink ability will shatter nearby windows when used.

Breakneck Speeds[edit]

Breakneck Speeds can be turned on by pressing Shift, and can be used whether or not SCP-173 is seen.
In this state, SCP-173 moves 1.7x faster, blinks 1.8x further, charges blinks twice as quickly, but is unable to kill players. The ability can be used by SCP-173 to quickly escape a dangerous situation as it allows them to move much more quickly at the cost of being unable to kill.
This mode ends when the player presses Shift again. There is a small grace peroid of 1.5 seconds after the ability is activated where pressing the Shift key will not cancel the ability. It will also ends automatically 10 seconds after SCP-173 is spotted.
The ability has a 40 second cooldown, the cooldown only starts after the ability ends.
