Following a lengthy philosophical discussion, including a discussion 
of Pascal's Wager, the apparitions increased in strength and clarity, 
allowing Oscar to obtain a clear photograph of the entity. He then 
presented the photograph to Alice for identification. To his surprise, 
Alice identified the photograph not as her husband, but as Subject B 
("Bob"), a young man with whom she had been acquainted during 
her younger years. 


Alice claimed that she and Bob had been romantically involved in 
the early 1940s, but their relationship had been suspended when 
Bob was drafted into the Second World War. During that war, Alice 
made the acquaintance of her eventual husband: a factory worker 
who had been classified 4-F due to a leg injury caused by an 
automobile accident. Two days after Bob received her "Dear John" 
letter, he was killed in Normandy during Operation Overlord. 


Alice's heightened emotional state caused the apparitions to 
increase in frequency and intensity, including physical 
manifestations. After a GOC operative was injured by a Luger bullet 
fired by one of the "ghosts," Central ordered termination of the 
subject. Operative Oscar requested permission to attempt a 
nonlethal "Soft Kill," citing Second Mission (Concealment) concerns. 
Permission was granted. 


No record remains of Operative Oscar's subsequent conversation 
with Subject Alice, but it convinced the Subject to manifest an 
apparition of "Bob" that night, the first time that she had manifested 


an apparition in her own presence. After receiving emotional closure 
with what she believed was the spectral entity of her old lover, the 
apparitions ceased manifesting entirely. Subject died three nights 
later in her sleep of natural causes. No further paranormal 
phenomena have occurred in the area since Subject Alice's death. 
Operative Oscar was commended for his actions. 


Overview 


There are over one hundred known instances of parathreats that 
operate by animating the corpses of the dead, ranging from simple 
prions to complex nanomachines. New ones are discovered on a 
regular basis, as diverse as the situations in which they are 
encountered. For this reason, Coalition operatives should familiarize 
themselves with the following three-step mnemonic (also known as 
the "SEX" method, for Secure, Evaluate, and eXterminate), for 
dealing with Type Gray outbreaks. 


Secure 


The first priority in any Type Gray outbreak is to Secure the area in 
which the outbreak is taking place. The following tasks should be 
carried out, in order of priority (most vital to least important). 
Individual situations will, of course, require revision of this general 
order. 


¢ Establish Worst Case Scenario fallback plan. Coordinate with 
security assets re: authorized Response Level. 

* Lock down the infested area and establish a secure perimeter. 

No persons are to be allowed in or out of this perimeter. 

Security personnel are to be informed to shoot on sight. 

Should GOC personnel be unavailable, local law enforcement 

or military assets may be commandeered under a standard 

cover story. 

Establish a headquarters within the infested zone. Said 

headquarters should be secure, and preferably non-adjacent 


to civilian defense points, so that compromise of civilian 
defenses will not threaten GOC assets. 

¢ Locate and make contact with any remaining civilians. Do not 
attempt to move civilians to headquarters zone: any civilians 
surviving within the infested area are to be left in place. 


Evaluate 


Because of the large number of Type Gray threat entities, it is 
imperative to establish the nature of the particular Type Gray 
outbreak. GOC personnel are to liaise with any medical or scientific 
personnel within the infested zone, and make first-hand 
observations of infested threat entities. Analyze collected data and 
refer to GOC Type Gray database. If Type Gray threat is determined 
to be a Known Threat Entity, refer to the Sterilization Manual for the 
particular KTE. 


Should data be insufficient, or if the parathreat is determined to be 
an Unknown Threat Entity, the following information should be 
recorded. 


Note: Due to multiple breaches of quarantine, GOC personnel are 
no longer to attempt to capture a live specimen of either infested 
persons, or the Type Gray threat entity itself, until the infestation is 
pacified. All Type Gray threat entities under observation and study 
are to be destroyed immediately upon determination of an effective 
Kill Method. 


Nature of physical and mental changes in the infested 
personnel. 


All Type Gray entities work by animating deceased matter. However, 
the amount of physical and/or mental faculties remaining after 
infestation vary between Threat Entities. Initial observation of 
infested individuals should establish three facts: 


* Remaining physical capacity: Speed of movement, agility, and 
strength. 
¢ Remaining mental capacity: Ability to solve problems, collate 


data, sensory capacity. 
* Social characteristics: Remaining pre-death personality or 
memories, presence of hive mind or internal factions. 


In most cases, Type Gray entities cause a 50% or more loss of 
physical capacity and reduction of mental capacity to simple hunger. 
Hive minds and internal factionalism have been recorded in less 
than 10% of cases. In most scenarios, a Type Gray infested human 
is slow, mindless, and violent. 


Method of Transmission. 


Many Type Gray threat entities are non-transmissible: infestation 
must take place directly towards dead flesh. However, many others 
can be transmitted through bodily fluids, through localized energy 
life forms, or through magical/religious means. Until said means of 
transmission is determined, all GOC personnel are to utilize Class 1 
Isolation Gear. Note: following the outbreak of the Memetic 
Cognitohazard Type Gray threat entity KTE-5321-Blit-Gray, 
"Eyeblight,” all Class 1 Isolation Gear has been revised to include 
visual distortion lenses. |\n addition, the GOC team on-site are to 
determine whether the Threat Entity is transmissible to humans only, 
or (should the Entity be able to infest animal or plant life) which 
forms of life are vulnerable to infestation. 


Effective Kill Method. 


In past experience, the following kill methods have been proven 
effective in Type Gray outbreaks. 


* Immolation: 99.9% 

¢ Destruction of Brain: 72% 
* Bodily Trauma: 54% 

¢ Toxins: 3% 

¢ Other: 2% 


Assessment of Effective Kill Method (EKM) should be carried out in 
the following manner. 


1. Locate a single Type Gray infested human and establish a kill 


approximately 5 days, and the maze has lasted for as long as 
50 days without noticeable shifting. These shifts can cut off 
exit from the maze, trapping personnel inside. 
* The maze is in a perpetual state of twilight, with no discernible 
sun, moon, stars, or other celestial references. The maze is 
also shrouded with a constant fog that reduces visibility to less 
than 10-20 meters. 
Exploration teams have encountered living creatures within 
the maze at distances of greater than 2 kilometers from the 
entrance. These creatures appear to be [DATA EXPUNGED] 
and have proven to be extremely dangerous, and as such all 
teams should try to avoid them if at all possible. 


SCP-648 came to the Foundation's attentionon //19 after two 
young children discovered the anomalous entrance and disappeared 
inside. Amnestics were administered to the parents of the children 
and several witnesses, and a cover story planted. 


Addendum 648-01: Initial Exploration Incident Log 


After attempts to remotely explore the maze failed due to the 
inability to transmit radio signals from within, a manned exploration 
of the maze was approved by O5- and conducted on / /200 by 
members of Mobile Task Force [DATA EXPUNGED}], led by Agent 

K_. After traversing approximately 3 kilometers within the 
maze, the team encountered a [DATA EXPUNGED] which roared 
loudly and charged the team. Although agents were able to kill the 
creature using their personal firearms, the sounds of additional 
[DATA EXPUNGED] approaching from nearby forced the team to 
retreat before they were able to collect any samples that could be 
later analyzed. Agent K has requested additional firepower for 
further exploration attempts. 


Addendum 648-02: Exploration Log, //200 


An attempt to scale the wall of the maze was made using Class D 
personnel. Although extremely difficult due to the anomalous 
slipperiness of the wall and the presence of thorns and [DATA 
EXPUNGED], subject D-6443 was finally able to scale a wall after 
being attached to a high-strength tether with over 500 meters of line. 
Experiment team noted that the voice of D-6443 was extremely 


zone. Test subject is to be secured, if necessary, to ensure 
sharpshooter accuracy. 

. Establish perimeter, including fall-back plan and fire support. 

3. Sharpshooter armed with scoped rifle, including underslung 
launcher, fires two rounds into center of mass. Assess result. 
If method is effective, cease testing. 

4. Sharpshooter delivers headshot. Assess result. If method is 
effective, cease testing. 

5. Sharpshooter loads and fires incendiary grenade. Assess 
result. If method is effective, cease testing. 

6. Sharpshooter loads and fires chemical grenade loaded with 
"Zee-Be-Gone" toxin cocktail. Assess result. If method is 
effective, cease testing. 

7. \f standard kill methods prove ineffective, withdraw to 
headquarters and contact GOC high command for further 
instructions. 


ie) 


eXterminate 


Following establishment of security, and determination of an 
Effective Kill Method, GOC Strike personnel are to sweep the 
infested area according to standard "Clean and Sweep" protocol. 
Personnel are to report back every two minutes with status update. 
Should 25% of sweeping personnel be lost, mission is to be aborted, 
GOC personnel withdrawn, and Response Level 3 assets deployed 
to incinerate infested zone. Should losses exceed 50% at any point 
during withdrawal, remaining personnel are to be considered 
expended, and immediate Response Level 3 operations carried out. 


Introduction 


A Regenerator (Type Red) is an overarching designation for any 
individual who possesses the ability to reconstitute damaged tissue 
and limbs. Contrary to popular belief, a Type Red is not 
indestructible. Numerous methods exist for disabling the 
regenerative ability of a Type Red, or liquidating the Type Red 


despite their abilities. In some cases, Type Reds will self-terminate 
through uncontrolled use of their abilities: however, most cases will 
require intervention by an operative. 


Forms 


Flawed Regeneration: This form of Type Red is low threat and can 
usually be engaged by a single operative. When injured, instead of 
replicating the lost tissue, the Type Red's body will instead fill the 
gap with a material unsuited to the area. For example, if a Flawed 
Regenerator experienced the loss of an arm, there is a chance it will 
be replaced with a large growth formed from tooth enamel. This form 
of Type Red will typically kill itself via accumulated minor injuries, if 
left alone. 


Limited Regeneration: This form of Type Red possesses the ability 
to slowly reconstitute lost tissue, and in some case limbs. Limited 
Regenerators can prove dangerous in combat situations, as 
permanent injury is difficult to maintain. See Techniques for more 
information on how to permanently liquidate them. 


Full Regeneration: This form of Type Red possesses the ability to 
regenerate lost tissue and limbs in a matter of seconds, making 
liquidation or permanent injury impossible. See Techniques for 
information on how to incapacitate this form of Type Red. 


Expanding Regeneration: To date, seven Type Reds of this form 
have been discovered and incapacitated. Engagement by anything 
less than a Response Level 5 effort comprising multiple Strike 
Teams is not recommended. Expanding Regenerators possess not 
only the ability to regenerate lost tissue and limbs, but also generate 
further limbs and organs, often drastically increasing in size during 
the process. This combination makes Expanding Regenerators 
formidable opponents. Further information on how to incapacitate 
this form of Type Red can be found in Techniques. 


Identification 


Initial identification of Type Reds usually takes place when an 
observer reports a person suffering an injury that heals unusually 
quickly. An Assessment or Strike team will then engage the target, 
move them to a secure location, immobilize them, and administer a 
sharps test. A small incision is made to the subject's palm, and the 
rate and nature of rapid healing assessed. 


Capture 


Type Reds are difficult to liquidate in the field. Operatives will often 
have to capture the subject before transferring them to another 
location for final liquidation. 


* Injury to the legs is effective against Limited Regenerators and 

some Full Regenerators. 

Alternatively, multiple and repeated injuries to the body will 

often incapacitate some Full Regenerators while their body 

repairs the injuries. 

A knife, stake or other sharp object can be forcibly embedded 

into the brain. Although the Type Red will attempt to 

regenerate brain and skull matter, the sharp object will prevent 

full regeneration. Recommended point of insertion is the base 

of the skull, through the brain stem and upper spinal cord. 

« In the case of Expanding Regenerators, liberal application of 
fire is recommended. This may make it difficult to capture or 
transport the still-burning subject. 


Techniques 


Incineration: The Type Red is placed into a mobile incineration 
trailer, which is then primed and ignited. Depending on the level of 
regenerative abilities, multiple applications of fire may be required. 
In extreme cases, incineration may be required in perpetua. 


Submersion: The Type Red is placed in a sealed container which is 
then completely filled or immersed in water. This will cause the Type 
Red to drown, regenerate brain functions and subsequently drown 
again, rendering the Type Red effectively incapacitated. An 


alternative to this method replaces the water with earth, concrete, 
molten metal, or another solid. 


Corrosion: Similar to Submersion, but replaces the water with high 
molar acid. 


Erosion: The subject is reduced to multiple smaller pieces by cutting 
or abrasion. In some cases, this can be effective on its own. In other 
cases, Erosion may be used to enhance the effectiveness of one of 

the other liquidation methods. 


Extreme cases may require the use of multiple methods in rapid 
succession. 


Overview 


While multiple parathreats possess shapeshifting abilities, the 
"proper" shapeshifter is a particularly tricky target to engage. Their 
familiarity and reliance on their trait potentially gives them advanced 
mastery and skill in using it, especially if they are a mortal species 
(where creativity and ingenuity are common). If unprepared, a Type 
Yellow could give the veteran operative a hard time, whether 
pursuing them or facing them. 


NOTE: Not all entities that possess shapeshifting abilities are 
applicable to the following methods. For more information on those 
entity types (such as Therianthropes, Paranormal Coulroform, and 
most strains of Hemovores), please see their specific entries 
(Talbot, Harlequin, and Wallachia respectively). 


Classification 


Type Yellow entities are classified into the following categories, each 
associated with a symbol for simplicity: 


¢ Transformation Type: Defining the full extent of the 
transformation. 


© Limited Transformation: Where the entity can 
manipulate only part of their body, whether it be one 
part at a time or one part exclusively. Associated with 
the letter "A".
