SCP-173 is one of the seven playable SCP classes in SCP: Secret Laboratory.
SCP-173 acts as an assassin class SCP, meant to quickly hunt down and eliminate a single target or small groups of players.
In Game
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
- 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
Neck Snap
When SCP-173 isn't being observed, they can press 
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
SCP-173 takes reduced damage from all firearms besides 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 unlike SCP-106's armor, 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
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 destory 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
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 make a marker appear on the ground. The marker can be moved by using the mouse. When the player releases 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.
Break Neck Speeds
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 situtation 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.
