All units (both human and vehicular) of SCP-3198 have been 
reduced dramatically to a ratio of approximately 1:64 of their original 
size with a similar reduction in mass. SCP-3198 seems to be aware 
of having been altered by an anomalous effect, but is not aware of 
specifically what effect has occurred. SCP-3198 is unable to 
correctly perceive its environment, believing materials, lifeforms and 
its current location to be anomalous in nature. SCP-3198 is also 
extremely hostile to almost all lifeforms.1 SCP-3198 has begun to 
consume small invertebrates that inhabit the area surrounding its 
current location for sustenance despite Foundation attempts to 
provide SCP-3198 with a more viable food source (which have been 
met with extreme hostilities from SCP-3198). 


Communication with SCP-3198 has so far not been possible. The 
voices of SCP-3198 members have become extremely high pitched, 
audible as "squeaking" with some words occasionally being 
discernible. SCP-3198 speech can only be understood by lowering 
the pitch and speed on recordings. It is also assumed that normal 
human voices cannot be understood by SCP-3198, describing them 
as a deep booming sound, both in person and via radio contact.2 


The vehicles used by SCP-3198 function exactly like their normal 
sized counterparts, though they require significantly less fuel to run. 
Handheld weapons and weapons attached to both the scout 
vehicles and attack helicopters are considerably less powerful than 
their full sized counterparts, but are still capable of causing 
significant damage to structures and living targets.3 


SCP-3198 largely inhabits the west side of Site-1394's attic, having 
created a fortified base out of wood, cardboard and insulation. 


Crohn's disease, brain and spinal cord injuries, and normally fatal 
infections or wounds, amongst other things. Interestingly, cancer 
does not seem to be affected, though the subject's physical 
condition was still vastly improved. 


During the second and third minute of exposure, subjects start 
experiencing unnecessary unrestrained cell growth, manifesting in 
quickly advancing dermal growths. These growths seem to mostly 
be benign tumors and calcium and fat deposits, which though 
sometimes painful and disfiguring, are not life threatening. 


During the fourth minute of exposure, increased bacterial and fungal 
growth occurs, creating conditions that grow increasingly dangerous 
for all exposed life, even in their new healthier states. Respiratory 
and digestive problems are quick to arrive in most cases, and 
become steadily worse as time progresses. 


Past five (5) minutes, the effects of SCP-407 seem to differ each 
trial. In all cases, trace elements of plants or fungus as well as any 
animal life present begin to grow and replicate uncontrollably, at 
varying rates, often shaping into new organisms. Full results have 
varied depending on the test, and on the objects present when 
SCP-407 is played. 


Addendum-407-01: SCP-407 was found in the home of Professor 

of , who had recently returned from research in the 
Amazon regions of northern Brazil. Agents were first alerted to a 
possible SCP when [DATA EXPUNGED] 


Addendum 407-02: The mold that eventually resulted from 
SCP-407's second test appears to be some sort of Cordyceps 
Fungi. Noted to be similar to mold encountered by SCP-507. Due to 
fear of fulfilling a fate similar to that observed by 507, testing using 
SCP-407 has been limited to using only the first twenty (20) minutes 
of the recording. 


Addendum 407-03: Below is a sample test run of SCP-407. For full 
research and experimentation notes, see Experiment Log 407. 
Sample Test Notes: 

<Test 2; SCP-407 played for 28m 32s. Within chamber; 1 D- 
Class personnel, unsterilized > 


SCP-3198 is able to access the first floor of 1394 by using the sides 
of the attic's stairs as a ramp, which has allowed the scout vehicles 
to be driven to the first floor. SCP-3198 has created a small tactical 
wall using Jenga blocks at the top of the stairs leading from the 
ground floor. This wall is usually guarded by one scout vehicle 
containing between three and four foot soldiers. 


MTF-Lambda-9 was last active during a containment breach of 
SCP-682 (See Incident-682-1). This breach had occurred after an 
attempt to shrink 682 to a manageable size using SCP-1056 (please 
see Experiment Log T-98816-0C108/682). En route to 

, SCP-682 ambushed Lambda-9, expelling a wave of unknown 
energy.4 Contact was lost; all units of MTF-Lambda-9 were 
presumed KIA. 


SCP-3198 was discovered 4 days later, 2 kilometers from the 
location of Incident 682-15 after agents responded to an incident at 
what is now Site-1394. The prior residents of 1394 had reported to a 
local pest exterminator of hearing "buzzing" and "scratching" coming 
from the attic, assuming the noise to be caused by wasps. When the 
exterminator investigated, they were attacked by SCP-3198. The 
exterminator sprayed pesticides over a small portion of SCP-3198's 
fortification before exiting the attic and contacting local authorities. 
The Foundation then took over control of the property to contain 
SCP-3198.

Addendum 3198-1: Incidents 


Incident-682-I 


The following is the transcript of radio contact between MTF- 
Lambda-9 and Task Force Control during Incident-682-I. 
Lambda-9's orders were to head to and set upa 
Forward Operations Base from which units could be sent to re- 
contain SCP-682: 


FOQU046:/001_SCP/Keter/Incident_Logs/682/ 


Incident-682-| 


MTF-Lambda-9: Task Force Control, we are 
about 5 kilometers out from . ETA is 10 
minutes. Over. 


Task Force Control: Copy that, Lambda-9. 
Be advised that 19-Overwatch has lost visual 
contact of the target. Target last seen heading 
west near . Over. 


MTF-Lambda-9: Copy that, Control. We are- 


A loud explosion is heard, shortly followed by 
gunfire and vocalisations from SCP-682. 


MTF-Lambda-9: Task Force Control, we have 
sight of the target! We have engaged. Our 
location is heading west. Switching 
comms to open channel. Over. 


Task Force Control: Copy, Lambda-9. 
Incapacitate target if possible; MTF and 
containment teams will be directed to your 
position. Over. 


Task Force Control directs all other MTF units 
and containment teams to Lambda-9's 
position. An unknown sound is heard over 
Lambda-9's radio, followed by a 7 second 
period of static. Lambda-9 begins 
communicating again; however, Task Force 
Control assumes this is random noise. The 
following speech from Lambda-9 is a 
transcription after analysis of the recording 
was conducted. 


MTF-Lambda-9: Task Force Control, 682 just 
did... something, some sort of energy wave 
was released. We've lost visual. We are, we, 
something's not right, control. Over. 


Task Force Control: Lambda-9, please report 
current status. Over. 


MTF-Lambda-9: Oh Christ, what is that 
sound? Command, are you reading this? Over. 


Task Force Control: Lambda-9, Lambda-9, 
do you copy? Requesting update on sitrep. 
Over. 


MTF-Lambda-9: Command?! What the fuck 
did 682 do to us?! 


Task Force Control: All units, Lambda-9 is 
Status Black; communications lost. Target last 


seen heading westbound from . 19- 
Overwatch, please proceed to . All 
remaining units, move to intercept target. 
Over. 


MTF-Lambda-9: Captain! Radio's fucked! All 
I'm getting is fucking screaming, what the fuck 
ha- 


Communication is cut off to Lambda-9 by Task 
Force Control. 


Incident-3198-A 


The following is a log of Incident-3198-A. The log is a transcription of 
events captured by Site-1394 video feeds on 25/06/__. Video 
footage is captured on Camera 4, which is situated on the west side 
of 1394's roof, just outside SCP-3198's location:§ 


FOU182:/001_SCP/Euclid/Incient_Logs/3198/ 
Incident-3198-A 


<10:14:25> Attack Helicopter 0582 is seen to 
depart Site-1394 through a hole in the roof. 


<10:14:31> 0582 proceeds to slowly turn 180 


degrees before flying alongside the roof for 
approximately 40 centimetres. 


<10:15:15> 0582 proceeds back inside 
Site-1394. 


<10:25:38> 0582 departs Site-1394 again. A 
blackbird can be seen approximately 1.3 
metres from 0582. The blackbird slowly 
approaches 0582. 


<10:25:51> 0582 turns to face the blackbird as 
it flies towards 0582. 0582 discharges its main 
gun at the blackbird, killing it. 


<10:26:23> 0582 hovers in places for 15 
seconds before moving south of Site-1394. 


<10:26:59> A number of seagulls fly towards 
0582 from the roof of Site-1394 and attack 
0582 off camera. 0582 reappears on camera 
shortly before one of the seagulls destroys 
0582's tail. 0582 then falls and hits the ground, 
resulting in its destruction. 


What remained of 0582 was recovered by Foundation 
personnel shortly after the incident. 


Foundation personnel outside of Site-1394 at the time 
were unaware of this incident. When questioned, they 
advised that the seagulls had been seen, and were 
presumed to be fighting over food; personnel were 
unable to perceive 0582 due to its size. 0582 was only 
noticed after it exploded upon impact with the ground. 


The hole SCP-3198 breached containment through has 
since been sealed. 


Addendum 3198-2: 


Communication logs 
Log-3198-A 


The following is a transcript from 20/06/_ where researchers 
attempted to re-establish communication with SCP-3198 after it was 
discovered. The communication problems between humans and 
SCP-3198 were unknown at this time. The following speech from 
SCP-3198 is a transcription after analysis of the recording was 
conducted: 


FOU182:/001_SCP/Euclid/Communication_Logs/3198/ 
Log-3198-A 


SCP-3198: Control, this is MTF-Lambda-9, do 
you copy? Over. 


SCP-3198: (Audible sigh) Task Force Control, 
this is MTF-Lambda-9, does anyone copy? 
Over. 


Researcher Sanders: MTF-Lambda-9, this is 
Level 3 Researcher Sanders. Please relay 
your status immediately. Over. 


SCP-3198: Agh fuck! What the fuck? 


Researcher Sanders: Lambda-9, can you 
hear me? Over. 


SCP-3198: This is you giant fucks, isn't it? 
Paul! I've got the giants on the phone, think 
they're pissed about us trying to blow them up. 


Researcher Sanders: Lambda-9, if you can 
hear me, | need you to listen. The hostiles you 
are targeting are friendlies, repeat, hostiles are 
friendlies, do not attack. Over. 


SCP-3198: Hey giants, how about you go suck 


682's dick and while you're at it, make it undo 
whatever the fuck it did to us? 


Researcher Sanders: Lambda-9, | believe 
there may be some communication issues with 
your radio. If you can hear me, plea- 


SCP-3198: Yeah, that's what | thought. 


Comm link is assumed to have been cut off by 
SCP-3198. 


Researcher Sanders: Lambda-9, is anyone 
there? Over. Lambda-9? 


Following this the transmission is analysed. 
Researchers attempt to re-establish contact for 
the next few days to no avail. 


Log-3198-B 


On 28/06/ _, Foundation communications analysts based at 
Site-1386 recorded a brief interchange between two instant 
message devices located at Site-1394. The devices were in use by 
SCP-3198. It was not known prior to this event that any members of 
MTF-Lambda-9 had been equipped with such devices when 
deployed during Incident-682-1.” The recording of this conversation 
is below: 


FOU182:/001_SCP/Euclid/Communication_Logs/3198/ 
Log-3198-B 


Hey, Tash is it working? It's Lydia. 


Yeah but batteries nearly dead, better 
make it quick. How's the wall holding up? 


The wall's fine, giant poked it's head round 
then ran off when we fired at it but..shit, | 
swear it had something that looked like a 
Foundation symbol on it. 


What? Are you sure? 


Not 100%, the guys didn't see it, they were 


too busy shooting at the damn thing and 
the symbol looked kinda fucked up like 
someone had just dragged bits of it to be 
out of place but I'm sure it looked like it. 


| think it's this place. It's just messing with 
your head. I'd keep it to yourself, don't start 
a panic. Last thing we need is everyone 
thinking the giants work for the Foundation. 


| get you but what if it isn't this place? What 
does that mean? 


Attempts to contact either recipient since have been 
unsuccessful. 


Addendum 3198-3: Recovered 
media 


On 30/06/_ ,ascout vehicle was captured by Foundation personnel 
after the main weapon had been disabled. Inside the vehicle were 
four foot soldiers later identified as Private Lang, Private Pimm, 
Sergeant Emmerson and Corporal Betson. As Foundation personnel 
were lifting the vehicle to remove the occupants, all four jumped 
from the vehicle, resulting in their deaths. 


Upon later inspection of the bodies, a Mobile Task Force field 
document was found in Betson's clothing with a letter having been 


written on the back. Due to the size of the item, a microscope was 
required to view it. Below are transcriptions of both sides of the 
document: 


FOU182:/001_SCP/Euclid/Recovered_Media/3198/ 
Document-3198-A 


Copy of Document-3198-A 


Mobile Task Force Field Document - 
Lambda-9 


Clearance: Level 3 


The following document is intended for the 
purposes of recording data that cannot be 
obtained through voice, video or 
photograph. All information recorded in 
this document must be done so with the 
express purpose of being returned to 
researchers. 


NAME: Natalie Emmerson 
RANK: Sergeant 
DATE: ????? 


Writing down all the information | can about 
where we are to try and figure out where 
"here" is. 


Breach was likely caused by either trying to 
terminate 682 with another SCP or 
experimental technology. 682 has likely gained 
the ability of that SCP/techology which seems 
to be the ability to send other lifeforms/objects 
to an alternate universe/dimension. The main 
question is, which SCP or what technology 
was used? 


Creatures: 


Giants - Humanoid in appearance, 1/2 a km 
maybe more in height, first giant we came 
across was able to spray some sort of toxin 
contaminating our food supplies (haven't seen 
this since, mechanical weapon or biological?), 
men near the trucks have suffered serious 
chemical burns. Sounds they make sound like 
a deep booming, almost like a constant sonic 
boom. Apparently not fans of our weapons. 


Airborne hostile "Death Hawks" - Possibly 
some sort of bird, attacked Chopper 0582 ina 
flock, only 0582 made visual contact so 
description is unclear. 


Various insectoids - ranging from 1 meter to 3 
meters in length, roughly the appearance of 
beetles, woodlice, ants. All hostile, but easy to 
deal with, have started consuming as food. 
Tastes like sh is not good but is edible. 


Location: 


Possibly some sort of mountain or mangiant 
made structure. Materials seem to be a couple 
of variations of a wood like substance, one 
variation was found in a block form with some 
sort of inscription on it (can't tell what language 
it is, likely something to do with the giants), 
plant or possibly some sort of fiber lines the 
ground (useful for construction of the fort), 
higher up the structure seems to be some 
stone/brick. 


Conclusion: 


The SCP used We are located inside an alt | 
don't know where we WE ARE FUCKED 
It doesn't matter where we are. It's not home.
