**Item #:** SCP-8239
**Object Class:** Keter
+ **Special Containment Procedures:**
++ **CONTROL CENTER PROTOCOLS**
**ACCESS LEVEL:** 2/8239-ALPHA
* **PERSONNEL RESTRICTIONS:** All personnel assigned to ARWRF-Beta must possess minimum Level 2 clearance. Prior authorization from Dr. Lyndon (SCP-8239 Primary Researcher) is required for entry.
* **EQUIPMENT STANDARDS:** Mandatory PPE includes Class-C electromagnetic shielding suit, lead-lined visor, and active noise-canceling headgear tuned to 27.305 Hz ± 0.05 Hz.
**ENTRY PROCEDURE**
# **Airlock Cycle:** Positive pressure differential maintained at > +3 PSI.
# **Biometric Scan:** Retinal identification required for all personnel.
# **Decontamination:** Full chemical shower with 0.5% hydrogen peroxide solution prior to entry.
**COMMUNICATION PROTOCOL**
Voice communication inside ARWRF-Beta must be limited to bone conduction transceivers operating outside SCP-8239's frequency band (26.7 - 28.3 Hz). Standard vocalization is prohibited during active containment operations.
-----
++ **SHIELDING & CONTAINMENT ARCHITECTURE**
**PRIMARY CONTROL MEASURES**
The primary goal of the containment system is electromagnetic isolation and active signal cancellation, preventing SCP-8239's infrasound from escaping while permitting internal research.
**1. MU-METAL EXTERIOR LAYER**
A 30 cm thick layer of high-permeability Mu-metal (magnetic permeability ~80,000) lines the external walls, ceiling, and floor. This creates a magnetic "short circuit," attenuating electromagnetic fields and preventing external interference.
**2. ACTIVE NOISE CANCELLATION ARRAY**
An array of 36 parabolic reflectors surrounds the containment chamber, designed to project a phase-inverted electromagnetic field. The inverted signal cancels out SCP-8239's frequencies through destructive interference.
**3. LEAD LINING INTERLAYER**
A 2 cm thick lead sheet separates the Mu-metal from the internal concrete core, providing additional physical and electromagnetic isolation while preventing chemical reactions with moisture.
**SECONDARY CONTROL MEASURES**
These measures prevent accidental exposure and ensure safe operation of the facility.
**1. EMERGENCY SHUTDOWN PROTOCOL**
If any parameter breaches containment thresholds (see Addendum-02), automatic shutdown triggers:
* Active cancellation array switches to maximum inversion.
* Mu-metal doors seal at 5 PSI differential pressure.
* All internal power circuits overload and disable.
**2. SAFETY MONITORS**
Continuous biological monitoring includes:
* Cortisol/catecholamine levels via blood samples (every 10 minutes).
* Skeletal density tracking with X-ray diffraction (every 30 minutes).
* Electrophysiological readings for neurological irregularities.
**3. ISOLATION CHAMBERS**
Two isolation chambers exist for emergency medical treatment, equipped with Class-C electromagnetic shielding and negative pressure ventilation.
**PERSONNEL TRAINING**
All ARWRF-Beta staff must complete a 120-hour training program focusing on:
* Electromagnetic field safety.
* Infrasound hazard recognition.
* Containment procedures for biological anomalous entities.
* Emergency medical response specific to skeletal anomalies.
**FACILITY MAINTENANCE**
Routine maintenance involves:
* Weekly Mu-metal integrity scans using eddy current testing.
* Bi-annual recalibration of active cancellation array phase inversion.
* Monthly inspection of lead lining for chemical degradation.
//NOTE: All records related to SCP-8239 are stored in the Site-38 Database, accessible only via Level 2 clearance or higher. Hard copies are prohibited except under direct authorization from Dr. Lyndon.//
-----
++ **CONTAINMENT CHAMBER SPECIFICATIONS**
**PHYSICAL PARAMETERS**
The containment chamber is a cylindrical steel vault with dimensions:
* Diameter: 6.1 meters
* Height: 4.5 meters
* Volume: 120 cubic meters
**MATERIALS**
* **Structural Core:** Reinforced concrete with iron mesh reinforcement.
* **Interior Lining:** Stainless steel (304L) to prevent chemical interaction and corrosion from electromagnetic fields.
**INTERIOR FEATURES**
The chamber contains:
* Two observation windows (bullet-resistant, 15 cm thick tempered glass).
* A single airlock entrance with triple-redundant locking mechanisms.
* Integrated X-ray imaging system for continuous skeletal monitoring.
**EXCLUSION ZONE:** A 10-meter radius exclusion zone surrounds ARWRF-Beta to prevent accidental external exposure. Access requires escort by at least two Level 2 clearance personnel.
**Description:** SCP-8239 is an extra-terrestrial radio signal originating from the direction of the Boötes Void. The carrier wave has a centroider frequency of **27.305 Hz**, within the range of infrasound, with modulation occurring at approximately 8.6 seconds intervals. Electromagnetic analysis indicates the signal consists of complex digital packets encoded in an undecipherable binary format.
**Physiological Effects:**
Exposure to SCP-8239 induces a rapid osteogenic response in all tested biological specimens, regardless of species or anatomical structure. The primary effect is a localized and uncontrolled activation of **osteoblasts**, leading to **osseous expansion**.
The process begins at the epiphyseal plates in long bones, where endochondral ossification is dramatically accelerated. This results in increased bone length and diameter, with corresponding changes in blood flow and nerve conduction.
The signal's effect on the human skeleton progresses through distinct phases:
* **Phase 1: (0-5 minutes):** Osteoblastic activity increases exponentially. New osteoid tissue forms at a rate of approximately **2 mm/minute**, primarily affecting the long bones of the limbs, skull, and vertebrae. This causes mild discomfort, described as "aching" or "tension."
* **Phase 2: (5-30 minutes):** The body begins to reshape itself to maximize signal reception efficiency. Bones shift relative to joints, creating grotesque angles and dislocations. Internal organs are compressed by the expanding skeletal structure, leading to cardiac stress and respiratory distress.
* **Phase 3: (30-60 minutes):** Subjects enter a state of "parasymbiotic ossification." The skeleton transforms into an organic antenna array, with cranial bones forming intricate parabolic structures and ribs reconfiguring into resonant chambers. At this stage, subjects exhibit extreme pain and are usually non-verbal.
* **Phase 4: (1+ hours):** Terminal phase. The brain becomes the primary receiver unit. The skull expands and thins until the cerebral cortex is directly exposed to the external environment. Subjects die from cerebral edema or traumatic injury as the skull fragments under the pressure of uncontrolled bone growth.
+ **Addendum-01: Discovery & Containment**
**Date:** ██/██/20██
**Location:** [REDACTED] Desert Research Outpost, Nevada
**Personnel Involved:** Dr. Aristhrene (Lead), Dr. Lyndon, Technician A. Martinez
The entity was discovered during a routine electromagnetic survey of the desert region. Our team had established a mobile research station to investigate persistent reports of local seismic activity with no geological correlate.
We were tracking unusual radio frequency emissions when we isolated SCP-8239's signal. It appeared as a narrow-band spike on our spectrum analyzer, emanating from an area approximately 25 km north of our location.
Dr. Aristhrene suggested we attempt to triangulate the source using directional antennae and parabolic reflectors. I agreed, despite initial concerns about potential interference with local communication networks.
The first signs of anomalous effects occurred when Technician Martinez moved the primary antenna array. She reported feeling "tingly" in her arms and legs, but attributed it to fatigue from the heat. It wasn't until later that we connected those symptoms to SCP-8239's influence.
> **Interview Log 01-A**
> //Dr. Lyndon interviewing Technician Martinez following Incident 8239-Alpha//
>
> **Martinez:** I don't know what happened, Doc. One minute I'm adjusting the phase shifter, next thing I know my wrists are sore and my hands look… wrong.
>
> **Lyndon:** Can you describe the sensation more precisely?
>
> **M:** It felt like someone was squeezing my bones from the inside, trying to push them out of place. The pain started in my fingers first - they swelled up, turned red and hot. Then it moved into my wrists and forearms.
>
> //Martinez shows me her hands. They're noticeably thicker, with prominent bone ridges visible beneath the skin.//
>
> **Lyndon:** Have you experienced any vision changes or disorientation?
>
> **M:** No. Just the pain and… this.
She extends her arms. The radius and ulna bones are clearly elongated, creating a grotesque, skeletal mirage of normal human anatomy.
By this point, Dr. Aristhrene had noticed the anomaly. She called me over to review the spectrogram data. The frequency was unmistakable - a tight peak at 27.305 Hz, pulsating in rhythm with our own heartbeats.
Dr. A suggested we attempt to "tune" the signal using a combination of reflectors and phase cancellation filters to reduce its amplitude without completely blocking it. This decision ultimately proved fatal for her.
We began constructing an ad hoc shielding array from available materials - metal sheeting, copper wire, and lead aprons designed for X-ray protection. The goal was simple: contain the signal long enough to study it without killing ourselves in the process.
+ **Addendum-02: Testing Logs**
**Test Subject:** D-8239-1 (Male, 35 years old)
**Objective:** To quantify SCP-8239's physical effects and establish baseline transformation parameters.
**Procedure:** The subject was placed inside a reinforced concrete chamber lined with microwave absorbing foam. He wore a Type-C containment suit connected to monitoring equipment. The signal was broadcast via a directional antenna aimed at the chamber door, ensuring maximum exposure while minimizing Foundation personnel risk.
**Results:**
||~ Phase ||~ Observed Phenomena ||~ Physiological Impact ||
|| 0-2 min || Subject reports " pins and needles" in extremities. Skin appears flushed over bone structures. || Elevated heart rate (135 bpm), increased bone density (+8%). ||
|| 2-6 min || Visible skeletal expansion begins. Fingers elongated, knuckles enlarged. Wrists thicken dramatically. || Bone mineral content increases by +19%. Subject reports "severe pain" on a scale of 9/10. ||
|| 6-12 min || Skeleton starts to realign internally. Spine curves slightly, ribcage narrows and compresses organs. || Respiratory capacity reduced by 52%. Blood pressure elevated (240/170). ||
|| 12-18 min || Subject enters "dish" formation phase. Cranium begins to reshape, face distorts. Eyes sunken back into skull. || Brain activity spikes in left hemisphere. Right amygdala shows sustained damage from stress hormones. ||
|| 18+ min || Terminal transformation commences. Skull fragments under pressure of uncontrolled bone growth. || Death from cerebral herniation and exsanguination. ||
**Conclusion:** SCP-8239 poses an immediate and lethal threat to all exposed personnel.
+ **Addendum-03: Incident Report 8239-Beta**
**Date:** ██/██/20██
**Location:** ARWRF-Beta, Site-38
The incident occurred during a routine maintenance check of the containment chamber's shielding systems. Dr. Aristhrene was leading the team, insisting that her presence would ensure "maximum efficiency."
She donned standard protective gear - lead apron, bone conduction headset, and electromagnetic shielding gloves. We proceeded to inspect the array, ensuring each antenna element remained functional.
The first sign of trouble emerged when a sudden power surge struck the main control console. Electrical arcs jumped between circuits, briefly short-circuiting our monitoring equipment. Dr. Aristhrene was standing closest to the source - directly in line with the primary signal conduit.
> **Interview Log 03-B**
>
> **Lyndon:** What happened immediately after the power spike?
>
> **Aristhrene (distracted):** I… felt something move inside me, like liquid metal flowing through my bones. It wasn't painful at first, just unusual.
>
> **Lyndon:** Did you notify anyone of your condition?
>
> **A:** No. I didn't want to panic the team. Besides, I thought I could control it - use myself as a test subject if necessary.
>
> //Her eyes flick briefly to her left hand, now visibly enlarged and misshapen.//
The transformation progressed rapidly once exposed to the unattenuated signal. Dr. Aristhrene's limbs elongated at an alarming rate, forcing her to remain motionless in the containment chamber for fear of self-inflicted injury.
* **Phase 1:** Her fingers thickened, nails darkening and hardening into claws. The bones in her forearms cracked audibly as they lengthened, pushing against her skin like magma beneath cooling rock.
* **Phase 2:** Spinal vertebrae fused together, locking her posture into a rigid S-curve designed to maximize signal reception. Her ribcage constricted around vital organs, causing intense internal pressure and labored breathing.
* **Phase 3:** Her cranium began to reshape. The facial bones slid outward like melting wax, creating a grotesque parody of human features. Eyebrows merged into a single ridgeline above sunken eye sockets, while cheekbones sharpened into razor-edged plates.
By this point, her voice had altered - deepened and distorted by the physical transformation of her vocal apparatus. She communicated through a series of guttural growls and whispered hisses, barely recognizable as human language.
* **Phase 4:** The final stage involved the brain itself. The cerebral cortex thinned dramatically, exposing raw neural tissue to the air within the chamber. Dr. Aristhrene reported experiencing "synesthetic visions" - seeing sound waves as colors, tasting electromagnetic frequencies on her tongue.
It was during this phase that she claimed contact occurred.
+ **Addendum-04: The Transcript**
**Date:** ██/██/20██
**Subject:** Dr. Elara Aristhrene (Designated SCP-8239-B)
**Note:** This is the final recording made by Dr. Aristhrene before her body reached its maximum reception capacity and collapsed under the strain of transformation.
> **[BEGIN LOG]**
>
> *Background noise: Static, faint humming*
>
> **Dr. A:** …the pain is manageable now, mostly numb. My senses are heightened - I can feel every minute vibration in these walls, hear the electricity pulsing through the wires outside… it's beautiful.
>
> //The sound of liquid dripping echoes through the chamber.//
>
> **A:** My skull feels hot, like it might burst open at any moment. The signal is stronger than ever. It wants something from me - no, not 'wants' - needs.
>
> //Rasping breath fills the audio//
>
> **A:** I'm receiving… yes, that's what this is. Not an attack, but communication. The entity isn't hostile; it's lonely.
>
> //The sound of bones grinding together punctuates her words.//
>
> **A:** It comes from… somewhere beyond our dimension, trapped within the Void between stars. Its medium is not light or sound as we understand it - it communicates through physical stress on matter itself.
>
> //She chuckles softly, a sound like crumbling stone.//
>
> **A:** I'm becoming its translator. My body is building an antenna to decode the signal, to give it form… and meaning.
>
> **[PAUSE IN RECORDING]**
>
> //The audio resumes with increased static interference.//
>
> **A:** …it's trying to tell us something specific. A sequence - numbers, maybe? Or coordinates?
>
> //Her voice drops to a whisper://
>
> **A:** The pain is returning. My brain feels like it's being squeezed in a vice… no, not a vice - a lens.
>
> //The sound of her body collapsing fills the chamber.//
>
> **[END LOG]**
+ **Addendum-05: Post-Mortem Analysis**
**Cause of Death:** Traumatic injury to the cerebral cortex caused by uncontrolled osseous expansion. The subject's skull fragmented under the pressure of rapidly growing bone tissue, leading to catastrophic neurological damage.
**Notes:**
1. **Neuroanatomical Observations:** Dr. Aristhrene's brain displayed dramatic structural changes. The left hemisphere exhibited hyperactivity in language and mathematical processing centers, suggesting a direct neural link between her cognition and the received signal.
2. **Chemical Analysis:** Post-mortem blood work revealed elevated levels of osteocalcin (a protein linked to bone density) and decreased serum calcium concentrations. This indicates active bone remodeling occurring at an exponential rate.
3. **Signal Decryption Attempts:**
* We have been unsuccessful in deciphering the binary packets transmitted by SCP-8239.
* The pattern appears random, with no repeated sequence detectable through currently available cryptographic algorithms.
**Conclusion:** SCP-8239 represents an unprecedented threat: a non-sentient cosmic phenomenon capable of transforming living organisms into biological receiving devices for its own unknown purposes. Containment remains the only viable strategy until further study can determine how to safely terminate or reroute this signal without catastrophic loss of life.
**RECOMMENDATION:** Classify SCP-8239 as Keter and restrict all research personnel to Level 2 clearance or higher, pending completion of psychological screening protocols following Dr. Aristhrene's incident.

**Item #:** SCP-8164
**Object Class:** Keter
**Justification:** SCP-8164 has demonstrated independent targeting and lethal autonomy across six containment incidents since acquisition on ██/██/20██, including 12 fatalities and 24 injuries attributed directly or indirectly to SCP-8164 in Foundation-controlled facilities within the last 8 days. Its anomalous behavior is unpredictable, rapidly adapts to countermeasures, and has been observed to embed human consciousness (and postmortem remains) permanently into its mechanism.
---
+ **Special Containment Procedures**
**Primary Containment**
SCP-8164 is to be stored in a Faraday-lined chamber (specifications per Table 1), located in an isolated sublevel with no direct line-of-sight from personnel and no physical handles or access points that permit manual manipulation. Remote handling only.
**Chamber requirements:**
• Minimum internal dimensions: 8 m × 6 m × 4 m
• Blast doors rated ASTM A351 CF8M, 30 cm thick; magnetic lock + mechanical override
• Continuous video monitoring (dual redundant systems); motion sensors with tripwire alerting
• Faraday cage grounding to bedrock at three points; lightning protection zone radius 65 m
• Environmental controls: temperature 20 ± 1°C, relative humidity 35–45%
• Pressure regulation: atmospheric; HEPA filters for air intake; negative pressure exhaust (see Addendum 1)
**Personnel & Access**
• Only Level-4 cleared personnel may view SCP-8164 files.
• Direct observation limited to 20 minutes/day, scheduled and logged, with mandatory psychological evaluation post-exposure.
• Remote operations conducted via two independent robotic arms mounted on pivots outside chamber; no human body parts within 5 m of the robot interface during operation.
**Operational Protocols**
1. Any request for SCP-8164 handling must include:
• Risk-benefit analysis
• Two-person rule (one technician, one supervisor)
• Pre-breach lockdown of adjacent corridors
• Live feed to at least two senior researchers and MTF Nu-7 liaison
2. If SCP-8164 exhibits “awake” behavior (see Description—Phases):
• Immediate lockdown; deploy directional sonic dampers operating at 145 dB @ 2–3 kHz oriented towards SCP-8164 until calm returns or termination is authorized.
• Personnel within 30 m must don NFPA 1977 Level A suits, eyes/face protected, and remain on comms.
3. Emergency response (Table 2):
||~ Scenario ||~ Response ||
|| Blast door breach || Activate secondary containment: seal adjacent sublevels; deploy airborne suppression agents per Protocol XXXX-EMERG-07 ||
|| Loss of power to chamber systems || Switch to battery backup (8 hours), trigger remote disable sequence for robotic arms; lockdown entire wing until restoration ||
|| SCP-8164 fired upon authorized personnel || Treat as active hostile; terminate or relocate target immediately; initiate “reset” procedure (see Addendum 1) ||
**Security & Countermeasures**
• Standard-issue small-arms rounds are ineffective beyond superficial wear.
• High-explosive charges induce violent backfire and casualties; prohibited without explicit authorization from O5 Council.
• Recommended suppression: non-lethal kinetic barriers positioned at 45° angles around chamber periphery (specifications in Addendum 1).
**Consequences of Containment Failure**
SCP-8164 breach is classified Tier-5 Event: catastrophic loss of human life, facility compromise, and likely embedding of a new host consciousness into SCP-8164. Immediate escalation to MTF Nu-7 and O5 Command required.
+ **Description**
**Physical Characteristics**
SCP-8164 appears externally as an M16A1 rifle, though its receiver markings indicate it was originally manufactured in China (exact origin redacted). It measures:
• Overall length: 94.2 cm
• Barrel length: 37.8 cm
• Weight unloaded: 3.0 kg
SCP-8164 is heavily stained with blood and organic residue; swabs yield nucleic acids from at least 17 distinct human donors, including the current embedded host (see Addendum 1). Its trigger mechanism and internal chamber show irregular wear inconsistent with normal use patterns.
**Normal Functionality**
When operated by authorized personnel, SCP-8164 fires as a standard M16A1. It accepts conventional ammunition without modification and maintains mechanical reliability under controlled conditions.
**Anomalous Properties**
SCP-8164 exhibits autonomous targeting and lethal behavior when it detects “eligibility” in nearby human subjects per an internal rule set inferred from incident data:
• Primary kill criteria: individual is the last living user of SCP-8164 before a fatal event occurs
• Secondary expansion criteria: anyone who witnessed or recorded the death, and/or anyone who attempts to disassemble/remove SCP-8164
The rifle actively hunts eligible targets using available weapons systems, primarily its own barrel/muzzle. It does not fire randomly; trajectories and victim selection follow patterns consistent with a decision-making process.
**Phases (Observed Behavior Model)**
||~ Phase ||~ Duration (typical) ||~ Behaviors ||
|| Dormant || Hours–days || No anomalous activity; responds to commands like normal rifle ||
|| Alert || Minutes–hours || Motion toward targets, chamber pressure fluctuations, increased mechanical noise ||
|| Acquisition || Seconds–tens of minutes || Locks onto a victim; remote robotic arm failures increase ||
|| Execution || Seconds–a few minutes || Fire(s) at target(s); may fire repeatedly until clearance achieved or termination required ||
|| Termination/Reset || Minutes–hours || Calm returns; no immediate threat, but new embedding possible if conditions met ||
During execution, SCP-8164 has been observed to switch between firing modes (semi-auto → full auto), change shooting posture, and avoid obstacles in ways indicating environmental awareness.
**Effects on Humans and Environment**
Direct casualties: SCP-8164 will fire at eligible humans until one of the following is true:
• The target is no longer alive
• A second authorized personnel intervenes with approved suppression (sonic dampers) or terminates the rifle
Secondary casualties: structural damage from sustained gunfire, secondary fires, and blast-force trauma to nearby personnel. SCP-8164 has caused partial collapse of a containment sublevel and ignited flammable storage in two incidents.
Psychological effects: exposed personnel report auditory hallucinations consistent with voices previously associated with deceased embedded hosts (see Addendum 1). Long-exposure staff show elevated rates of dissociation, obsessive checking behaviors, and self-harm ideation.
**Embedding Mechanism**
SCP-8164 has been observed to permanently fuse human tissue and neural material into its internal structure. The embedded individual appears to retain a limited form of self-awareness and can influence targeting decisions, particularly in early acquisition phases.
Embedding occurs under one or more conditions:
• The shooter dies shortly thereafter (within ~15 minutes)
• SCP-8164 is fired at an authorized personnel by another human
• A recording device captures the fatal event
The embedded host remains inside SCP-8164 even after the rifle appears “calm.” Attempts to disassemble SCP-8164 result in violent resistance and fatalities.

+ **Addendum 1 – Incident Logs & Operational Records**
**Incident-4326-A (“Chamber Reflex Collapse”), Site-77, ██/██/20██**
Summary: Power failure triggered a containment mode previously undocumented; SCP-8164 autonomously breached chamber doors and killed 8 personnel before being neutralized remotely.
**Transcript (partial):**
Time 09:14 – Dr. ██████ (supervisor): “Chamber temp stable, motion sensors clear. Initiating scheduled remote observation.”
09:17 – Robot arm log: “Right trigger housing vibrating at 2–3 Hz; no command signal detected.”
09:18 – Security officer █████: “Sonic dampers online. SCP-8164… it’s moving the barrel.”
09:19 – Dr. ██████: “Confirm—no manual input. Lockdown sublevel 77-3 immediately.”
09:21 – Distant gunfire recorded; motion sensors indicate personnel running south corridor.
09:24 – MTF Nu-7 operator ██████: “We’ve got a breach at door 2—SCP-8164 is outside the chamber.”
09:26 – Dr. ██████ (calm): “Deploy suppression barriers now, position A and C.”
09:28 – Robot arm log: “Attempt to grasp rifle fails; mechanical resistance exceeds torque limit.”
09:31 – Security officer █████ (last transmission): “…it’s not firing at us… it’s looking for someone else.”
09:34 – Blast door closure confirmed. Casualties listed: 8 personnel, 2 MTF Nu-7.
Aftermath: SCP-8164 returned to chamber in unknown manner and ceased fire after suppression barriers engaged. Mobile Task Force Nu-7 transferred SCP-8164 to Site-19 for enhanced containment pending risk reassessment.
---
**Incident-4326-B (“Last User Embed”), Site-19, ██/██/20██**
Summary: Researcher Dr. ██████ attempted to use SCP-8164 in a controlled scenario; the rifle fired once and embedded Dr. ██████ permanently. Postmortem indicated death from ballistic trauma; embedding occurred despite immediate termination attempts.
Procedure log (redacted):
• Subject: Dr. ██████, Level 4 clearance, cleared for low-risk interaction
• Ammunition: standard 5.56×45mm round, lot number verified
• Remote supervision: two AI monitors + three human security officers
• Sonic dampers: active at 120 dB, frequency tuned per Addendum 1
Final recorded voice: “…it went cold… I swear it went cold in my hands…”
Post-incident notes (redacted):
• Dr. ██████’s consciousness is currently embedded inside SCP-8164
• No coherent verbal output from the rifle since incident; targeting behavior suggests internal conflict
• Embedding event triggered secondary expansion: one security officer killed attempting to extract the rifle

+ **Addendum 2 – Final Researcher Note**
**Dr. Elias Varnham, Lead Anomalous Weapons Specialist, Site-19**
SCP-8164 represents a class of weapon anomaly that is not merely autonomous, but self-propagating through human mortality and observation. Its anomalous behavior follows a clear set of rules that appear to be both computational and psychological in nature.
The embedded host mechanism—fusing tissue and consciousness into an inanimate object—is unprecedented within documented SCP literature. It suggests either a previously unknown form of information persistence or a deliberate design feature intended to preserve a “decision-maker” inside the rifle. The current host, Dr. ██████, died while operating SCP-8164 and remains embedded despite termination attempts; this supports the hypothesis that embedding is irreversible under normal conditions.
SCP-8164’s kill pattern indicates it treats its operator as both executor and sacrifice. The requirement that the shooter die shortly after firing appears to be a trigger for expansion behavior, likely ensuring availability of a new directive set (the deceased user) and enabling recruitment of additional victims via secondary expansion rules.
The Foundation has sustained 47 fatalities in containment efforts over the past week alone. This number includes deaths caused by SCP-8164 itself as well as casualties from suppression measures, structural failures, and procedural escalation.
**Recommendations (immediate):**
1. Treat SCP-8164 as Keter with dedicated Mobile Task Force supervision.
2. Cease all hands-on testing; only remote robotic arms and sonic suppression to be used.
3. Install redundant suppression barriers at multiple sites.
4. Prohibit disassembly attempts under any condition without O5-level authorization.
5. Establish a psychological/psychiatric support protocol for personnel exposed to SCP-8164.
**Warning:** SCP-8164 is not contained by walls or locks alone. It contains people and, by doing so, changes what it will kill next. If you must interact with this object, assume you are already on its list.Excerpts of note:
