A Foundation disinformation team is to monitor the internet and 
social media for accounts of kangaroos driving vehicles, as well as 
disseminating information on the importance of driving cautiously 
near wildlife-inhabited areas. 


The habitat occupied by SCP-3502-1 is currently contained in a 50- 
hectare nature reserve plot of land purchased and maintained by a 
Foundation front company, which has established a small outpost 
(currently staffed by a team of two containment specialists, two 
security guards, and one researcher) at the western edge of the 
area. A barbed wire perimeter fence has been constructed to deter 
trespassers. Unauthorized individuals attempting to enter the 
reserve are to be amnesticized and turned away. 


Description: SCP-3502 is an anomalous phenomenon centered on 
the the small town of , of Queensland, Australia. SCP-3502 
affects "kangaroo crossing" signs (consisting of an icon of a black 
kangaroo on a yellow diamond shape), commonly found in rural 
regions of Australia. The anomalous effects of SCP-3502 activate on 
a monthly basis, usually from 3rd to the 15th of every month. 
SCP-3502 has been observed to manifest more often during winter. 


When a human individual drives a vehicle! past a sign affected by 
SCP-3502 without decreasing their traveling speed, they will 
experience a sudden loss of consciousness within 30-60 seconds of 
passing the sign. Examination of affected individuals indicates 
symptoms similar to those caused by blunt force trauma to the head. 
After the vehicle driven by the individual slows or ceases movement, 
an instance of SCP-3502-1 will manifest and approach the vehicle. 


SCP-3502-1 refers to a mob of eastern grey kangaroos (Macropus 
giganteus) possessing unusually high levels of intelligence and 
proficiency for handling human implements. Of note, while 
SCP-3502-1 individuals appear to be in healthy condition, all 
instances exhibit some form of injury, ranging from bruising to 
misshapen limbs. 


Upon manifesting following an occurrence of SCP-3502, 
SCP-3502-1 entities will proceed to hijack the vehicle and forcibly 
remove any occupants. The SCP-3502-1 instance will then proceed 
to attempt to enter and drive the vehicle to a remote area of 
uninhabited land. GPS tracking has recorded vehicles being 
transported as far as 45km from the initial location of a sign affected 
by SCP-3502. If unable to move the vehicle, SCP-3502-1 instances 
will instead ransack the interior, smashing windows and tearing out 
any soft materials available. Occasionally, SCP-3502-1 instances 
will also remove tires from the sabotaged vehicles. 


Addendum SCP-3502-1: During a reconnaissance session on / / 

, a Foundation surveillance team was able to discover the habitat 
of a group of SCP-3502-1, located approximately 20km from a sign 
affected by SCP-3502. 


It was noted that the living grounds appeared to be furnished with 
vehicles from previous Foundation experiments, arranged in lines. A 
large group of SCP-3502-1 was observed tending to multiple stolen 
vehicles in different states of disassembly, with native grasses and 
vegetation growing within the chassis of each vehicle. Other 
SCP-3502-1 instances appeared to be constructing a rain shelter 
from loose vehicle parts and sheet metal, while young SCP-3502-1 
instances were sleeping nearby in berths made of truck tires and car 
cushions. 


and adjoining municipalities arrive at the club; although the 
night invariably begins identically to any other club, over the course 
of the night the civilians present fall into "roles" in one of | currently 
documented sequences of events (termed "Scripts" by Foundation 
operatives working on SCP-453). Over the course of the evening, 
generally according to Script, civilians will depart the club and return 
home, maintaining only partial memories of the night. All surviving 
civilians depart before 0400 every night. 


SCP-453 has existed in its current location for as long as 
Foundation records exist. Archaeological evidence suggests a 
wealthy Roman senator, known for extravagant nightly parties, had 
a villa in the location as early as__B.C.E.; the Foundation has had 
possession of the site since 1 . On several occasions the building 
has been torn down or destroyed; outdoor parties continued to 
persist nightly at the site. When the site itself is rendered 
inaccessible, civilian partygoers will gather as near as possible to 
the site and begin an impromptu street party; this party rapidly 
devolves into a riot (see Document 453-1, Complete List of Known 
Scripts, attached). 


The club in its current configuration was designed and built entirely 
according to Foundation specifications. All core construction 
materials are SCP containment grade, to limit damage due to the 
more violent Scripts. Dr. Moriglioni has observed that the building 
has shown some self-mutational ability. Of particular note has been 
the gradual shift of the location of the secure locker containing 
suppression weaponry for staff use: it has moved closer and closer 
to the men's washroom. At this time it remains in the secure staff 
section. Other sections of the building have slowly moved and 
changed in similar ways. 


A complete log of known Scripts is attached as Document 453-1. 
The 'selection' of a Script appears to be semi-random, although 
various stimuli will encourage particular Scripts to occur (for 
example, Script 117 "The Silver Harlequins" has only been observed 
when more than 15 club attendees are over the age of 60). Please 
note that while Script logs detail "pertinent events", all events in the 
club aside from staff actions become Scripted at around 2100 hrs 
(varies depending on Script). Participants begin speaking in Latin 


Discussion regarding the viability of attempting communication with 
SCP-3502-1 is underway. All future ventures to the SCP-3502-1 
habitat are to be performed on foot, starting from 5km away from the 
habitat.

SCP-3503: Panic is Pure, Trauma is True, Suffering is 
Sweet, and Death's a Delight 


Item #: SCP-3503 
Object Class: Keter 
Threat Level: ® Orange 


Special Containment Procedures: Foundation webcrawlers are to 
monitor social media, online support groups and discussion boards 
for Post-Traumatic Stress Disorder (PTSD), and correspondences 
between psychiatrists and therapists (particularly those involved in 
the treatment of PTSD) for evidence of SCP-3503 infection. 
Foundation assets embedded in psychiatric circles are to do the 
same. News and police reports concerning domestic abuse, sexual 
assault, and acts of mass violence are to be monitored for indicators 
of stage 3 SCP-3503 infection. 


The Foundation has commissioned Mobile Task Force Rho-93 
"Goatbusters" to combat and contain the influence of SCP-3503. 


If an SCP-3503-positive individual is identified, MTF R-93 is to 
deploy to the individual's location and perform Procedure 701- 
Crafty. 


+ Show Procedure 701-Crafty Description 


The affected individual (Henceforth referred to 
as "the focus" for clarity) is to be administered 
Memetic Agent 3503-Man-About-Town 
(Henceforth referred to as Meme MAT for 
clarity), after having been interrogated for 
intelligence that could be useful to the rest of 
the procedure. Subsequently, the focus's 
family, friends, co-workers, and anyone else 
who they were in the vicinity of on a regular 


basis (Such as sexual partners, therapists, 
teachers, etc.) are to be evaluated for possible 
SCP-3503 infection. Then, anyone who lives 
or works within a 70 meter radius of the 
focus's residence and workplace are to be 
similarly evaluated, as are people who work at 
or frequent other locations frequented by the 
focus, such as bars or hobby shops. If the 
agent performing the evaluation of any 
individual believes there is a reasonable 
suspicion that the person they are evaluating 
may be SCP-3503-positive’, that person is to 
be administered Meme MAT. All responding 
MTF R-93 agents are also to be administered 
Meme MAT. Finally, the focus's community will 
be placed on a watchlist of communities with a 
high risk of SCP-3503 infection. 


If the focus is in stage 3 of infection and has 
committed an act of SCP-3503 motivated 
violence, the step in which the focus is 
administered Meme MAT may be skipped so 
that the focus can be contained by the 
foundation for research purposes, at the 
discretion of the SCP-3503 containment lead. 
Misinformation is to be spread that the focus 
died as a result of resistance to their crimes. 
All parties involved are to be amnesticized and 
given false memories supporting this account. 


In recognition of the great difficulty of containing SCP-3503, and the 
danger it poses, the O5 Council and Ethics Committee have 
authorized the use of Blarney Stone Class Memetic Agents 
(Sometimes colloquially referred to as a memetic "truth serum" by 
Foundation personnel.) to compel full cooperation in the process of 
identifying SCP-3503-positive individuals or the administration of 
Procedure 701-Crafty. Non-Foundation personnel who are 
administered a memetic agent in the process of SCP-3503 
containment efforts should be amnesticized. 


The Foundation currently has 14 Stage 3 SCP-3503 patients in 
containment for research purposes. They are contained in a 
Site-172 satellite facility, constructed 120 meters away from the 
nearest point of the primary Site-17 complex3. Any or all of these 
infected individuals can be terminated at any time if the current 
SCP-3503 containment lead feels they pose a threat to Foundation 
personnel or the other anomalies contained at Site-17. 


Personnel working on SCP-3503 containment or research must 
disclose any potentially traumatic experiences they have during their 
work on SCP-3503 or have had prior. 


Description: SCP-3503 is a contagious form of Post-Traumatic 
Stress Disorder (PTSD). SCP-3503 has all the symptoms of 
standard PTSD, such as dreams or intrusive memories related to 
traumatic events, great distress in response to trauma related cues 
or triggers, and an amplified "fight or flight" response. However, 
SCP-3503 patients also exhibit a set of additional symptoms that 
manifest over time. SCP-3503 infection can be roughly categorized 
in 3 stages. 


Stage 1: Stage 1 lasts an average of 5 to 6 years, with a standard 
deviation of about 2 years. Stage 1 is almost indistinguishable from 
non-anomalous PTSD. The only distinguishing feature of stage 1 is 
that patients often have dreams involving satyrs‘4, or creatures 
similar to satyrs. Often, the satyrs seem out of place in the dreams 
they appear in. Stage 1 patients with high dream recall report as 
many as 40% of their dreams involve satyrs in some way. Satyrs are 
rarely the focus of these dreams. Dreams that recreate the traumatic 
experience that led infected individuals to contract SCP-3503 almost 
always include satyrs. 


Stage 2: Stage 2 lasts an average of 2 to 3 years, with a standard 
deviation of about 8 months. In stage 2, infected individuals begin to 
develop a positive opinion of their PTSD, feeling that having PTSD 
positively affects their psychological state. When questioned about 
this unusual opinion, SCP-3503 patients are generally entirely 
unable to explain why they feel this way. Some exceptionally 
articulate patients can describe that PTSD feels "correct" or 
"natural," but are unable to give a more detailed explanation. There 
is only one known SCP-3503 patient capable of explaining the 


rationale behind this symptom in detail, see Document-3503-A. 
Satyr dreams increase in frequency during stage 2. 


Stage 3: In stage 3, the infected individual's positive opinion of their 
PTSD becomes much stronger than in stage 2. As a result, the 
majority of stage 3 SCP-3503-positive individuals come to believe 
that it would be moral and desirable to give others PTSD. Stage 3 
patients gain a vague, intuitive understanding of how SCP-3503 is 
transmitted (see below). Most begin exhibiting uncharacteristically 
abusive behavior towards family and close friends®, and some even 
attempt to commit acts of mass violence, such as a mass shooting 
or public bombing. These acts of mass or individual aggression are 
generally planned in a manner which avoids fatalities but focuses on 
injuries, induced panic, and overall stress. Stage 3 patients also gain 
the ability to rapidly (within a few days) advance stage 1 or 2 
patients to stage 3 by discussing PTSD with them. About 30-40% of 
stage 3 patients develop uncharacteristically misanthropic beliefs 
and become sympathetic to or supportive of anarcho-primitivist 
ideas. Satyr dreams increase in frequency and intensity during stage 
3, with satyr dreams where the satyrs are the dream's focus 
becoming common. A small (<6%) amount of stage 3 infected 
individuals report briefly seeing satyrs while awake, usually in their 
peripheral vision, in mirrors, or just after waking up. 


Each SCP-3503-positive individual has a transmission radius. The 
exact size of the radius varies from individual to individual, but the 
great majority (>90%) of infected individuals have a radius that is 
between 50 and 60 meters. If an individual experiences a traumatic 
event while within the transmission radius of an SCP-3503-positive 
individual, or had experienced a traumatic event in the recent past® 
and then entered said transmission radius, that individual may 
contract SCP-3503. Testing’ has indicated a susceptible individual 
must spend approximately 20-30 continuous seconds inside a 
transmission radius to be infected. 

There have been numerous documented cases of susceptible 
individuals who spent time inside a transmission radius, but who did 
not contract SCP-3503, just as not all who experience a traumatic 
event get PTSD. However, there have been no documented cases 
where an SCP-3503 susceptible individual spent time in a 
transmission radius and then contracted non-anomalous PTSD. It is 


therefore believed that the SCP-3503 contagious agent "modifies" 
typical PTSD into SCP-3503. 


Though the conditions for the spread of SCP-3503 are fairly well 
understood, the mechanism by which SCP-3503 spreads is very 
poorly understood. 


+ SCP-3503 Transmission Theory Summary 


The current best model the Foundation has for the 
spread mechanism of SCP-3503 is that it spreads via 2 
or more sub-mechanisms working in tandem. One of the 
mechanisms is psionic in nature, the other or others are 
unknown. Further, the psionic mechanism is not 
essential to the spread of SCP-3503, but serves to 
"bolster" the other mechanisms in some way. 

Pertinent Evidence: 


¢ An individual who contracts SCP-3503 does not 
need to be able to see, hear, or perceive the 
relevant SCP-3503-positive individual to become 
infected, nor do they even need to be aware of the 
existence of the person infecting them. Therefore, 
SCP-3503 cannot be memetic or 
cognitohazardous in nature. 

¢ SCP-2608 is vulnerable to the transmission radius 

of an SCP-3503 patient. 

Prior to recent developments which indicated its 

total unsuitability for use in containment or 

research, SCP-148 was tested on SCP-3503. It did 

not nullify SCP-3503 entirely, but did demonstrate 

an ability to reduce the transmission radius of 

infected individuals by an average of 61%. 

¢ The size of an SCP-3503-positive individual's 
transmission radius is proportional to their psionic 
aptitude. The largest transmission radius ever 
discovered by the Foundation (71 meters) was that 
of Jennifer M —_, who scored in the 98.5th 
percentile on a psionic aptitude test. The smallest 
known (36 meters) was that of D-207-8649-3307, 
whose psionic aptitude was pushed below the
