 Item Number SCP-173 Object Class Euclid Special Containment Procedures Item SCP-173 is to be kept in a locked container at all times. When personnel must enter SCP-173's container, no fewer than three may enter at any time and the door is to be relocked behind them. At all times, two personnel must maintain direct eye contact with SCP-173 until all personnel have vacated and relocked the container. Description Moved to Site-1993, Origin is as of yet unknown. It is constructed from concrete and rebar with traces of Krylon Brand spray paint. SCP-173 is animate and extremely hostile. The object cannot move while within direct line of sight. Line of sight must not be broken at any time with SCP-173. Personnel assigned to enter the container are instructed to alert one another before blinking. Object is reported to attack by snapping the neck at the base of the skull or by strangulation. In the event of an attack, personnel are to observe class 4 hazardous object containment procedures. Personnel reports sounds of scraping stone originating from within the container when no one is present inside. This is considered normal and any change in this behavior should be reported to the acting HMCL supervisor on duty. The reddish brown substance on the floor is a combination of feces and blood. Origin of these materials is unknown. The enclosure must be cleaned on a bi-weekly basis. What the f**k are you looking at? John Avery, personally known as D5933, shouted at the other D-class in the cell. SCP-173, what the f**k are you looking at? came to reply. This worried John as he was staring intently at SCP-173 and the other D-class was standing behind John facing the other direction. Then John heard the worst sound any human being has ever heard, a sneeze coming from six inches behind his head. For a second John remembered an episode of Mythbusters he had seen before being arrested. Before coming here, were they tested to see if someone could sneeze with his eyes open. He never saw the end. There was a sick, wet thud, a horrible ripping sound and a scream that ended too quickly. F**k! John managed to get out. SCP-173, Addendum 1. Some data expunged, SCP-173, appeared to multiply, producing two identical copies. Two D-class personnel were killed. It is unknown how this process occurred. Each instance of SCP-173, now labeled SCP-173-1 and SCP-173-2, is to be moved to individual cells each following original containment procedures, SCP-173 Addendum 2. When data expunged, a second multiplication event occurred, SCP-173-1-4, are to be each contained as per original containment procedures, objects reclassed as Keter, SCP-173-3. Security breach occurred on data expunged. Assuming a simple geometric regression, at least 61 copies of SCP-173 are as of now unaccounted 4. It is unknown how they replicated so fast, or how they replicate at all. Video evidence of the containment breach shows multiple instances of SCP-173 working in unison across multiple cells to achieve the breach. Most of the instances still in captivity appear to have formed a rear guard, blocking Foundation agents from pursuing other instances. It is theorized that SCP-173 has a Hive Intelligence, where intelligence scales with the number of nearby copies. See revised security procedures for containing SCP-173 copies. Revised Special Containment Procedures. All copies of SCP-173 are to be contained in form-fitting metal containers, and sent using SCP-173-2 to the now abandoned Foundation facility on the Moon. They are to be fitted with tracking colors that will detect if any of them leave the Moon. SCP-173 Addendum 4. SCP-173 has caused a breach in secrecy for the SCP Foundation. Estimates at this time are roughly 500,000 civilian deaths across North America in the last 48 hours due to SCP-173, and hundreds of thousands of sightings and pieces of video evidence. Computer television news programs have obtained video of SCP-173, and are providing instructions for avoiding instant death. Dr. Bright is in charge of the containment. SCP-173 Addendum 5. SCP-173 has besieged and destroyed four Foundation facilities near simultaneously in the last 24 hours. Each instance shows the characteristic strength exhibited in the original, and thousands working in unison are capable of ripping open concrete bunkers and compromising foot-thick steel doors. Research is ongoing to find a way to combat this threat. Personal log of Dr. Bright. Date expunged. I've been killed 37 times in the last week. They can smell me somehow, regardless of what body I'm in. The majority decision of the remaining O5s is that this is an XK, and they're gonna deal with the problem. Or the Russians are. They're evacuating this base, which means there won't be a single Foundation scientist anywhere in the new world. They say they're gonna try to evacuate the surviving civilians, but I doubt it. There can't be more than a couple hundred people in all of North America. The only good news is that about 150 of the bastards teamed up and ripped SCP-682 apart. Brought a smile to my face. Revised Special Containment Procedures. Containment Zone X1, formerly North and South America, is to be denied access. Following saturation nuclear bombing on date expunged, number of SCP-173 instances has been reduced. All available Foundation resources are to be redirected to monitoring the ocean to ensure the integrity of Containment Zone X1. Foundation adjuncts from national navies are to perform around-the-clock patrols and sonar sweeps. Detected instances are to be contained and removed to SCP-173 for transport to the lunar containment site. SCP-173, Addendum 6. Right-sighting of SCP-173 in... Wales, the United Kingdom. Nuclear bombardment authorized and executed. No survivors. End of file.
