The view from the observation room window shows a static, 
repeating scene that lasts approximately 11.3 seconds before 
repeating. Visible through the window is a room of the same 
dimensions and layout as the factory floor, but painted white and 
sterilized. Set up in the middle of the room is a huge electronic 
device of indeterminate function covering at least 50 square meters 
and extending approximately 2 meters in height at its highest point. 
Five individuals in white clean suits appear to be working on the 
device. 


Approximately 5.9 seconds into the scene, the employee entrance 
door bursts open and four individuals wearing black tactical armor 
with no identifying marks or emblems enter the room and open fire 
on the research personnel. At 11.3 seconds, the device in the center 
of the room emits an intense flash of light and radiation, and the 
scene resets. Analysis of thousands of instances of the scene has 
shown no variation in the sequence. 


So far, all attempts at interacting with the scene have failed; any 
attempts to breach the window or door from within the observation 
room are met with resistance inconsistent with the suggested 
strength of the materials comprising their frames. To date, all 
attempts that have resulted in successful penetration of the door or 
window have resulted in the damage being instantly reverted along 
with the sequence during the burst of light. Any tools or limbs 
extended outside of the observation room are cleanly severed, and 
have never been found. 


Research is ongoing into the nature of the device at the center of 
SCP-176, as well as the identities of the individuals involved. 


Addendum 176-1: Further Analysis of Individuals in SCP-176 


Analysis has yielded the following information regarding the 
individuals visible in the scene: 


Unidentified researcher #1: male Caucasian, approximately 
40 years of age, with brown hair and green eyes. Stands in 
the southeast corner of the room, reading from a standing 
monitor. Hit three times in the chest by automatic fire at 
approximately 8.1 seconds and appears to be killed instantly. 
Unidentified researcher #2: male Asian, approximately 35 
years of age, with black hair and brown eyes. Stands to the 
left of researcher #1, carries a clipboard with indecipherable 
writing on a note pad. Hit once in right shoulder at 8.0 
seconds before dropping to the floor, out of sight behind the 
device. 

Unidentified researcher #3: female Caucasian, 
approximately 40 years of age, with brown hair and amber 
eyes. Sits at a desk in the southwest corner of the room, 
working at a computer station. Is out of the line of sight when 
the gunfire begins, and takes cover under the desk. Appears 
to be reaching for a weapon of some sort shortly before the 
end of the sequence. 

Unidentified researcher #4: male Caucasian, approximately 
45 years of age, with brown hair and indeterminate eyes. 
Stands in front of the device to the northeast, with his back to 
the observation room. Shot twice in the head at 7.2 seconds, 
killed instantly. 

Unidentified researcher #5: male, indeterminate. Stands in 
the northwest corner, mostly obscured. Presumably shot at 
approximately 7.8 seconds and drops down, out of sight. 
Unidentified assailant #1: male, indeterminate, wielding a 
suppressed M4A1. Enters first, shoots researcher #4 and 
researcher #5, then moves towards the device. 

Unidentified assailant #2: male, indeterminate, wielding a 
suppressed MPS5N. Enters second, turns left and shoots 
researcher #1 and researcher #2, then sweeps towards the 
southeast. 

Unidentified assailant #3: male, indeterminate, wielding a 
suppressed MP5N. Enters third, turns right and moves under 
the observation room. 

Unidentified assailant #4: male, indeterminate, wielding a 
suppressed TMP. Stays at the door, covering the others.

SCP-177: Checkmate 


Item #: SCP-177 
Object Class: Safe 


Special Containment Procedures: Due to the safe level of the 
object, SCP-177 is to be contained in Dr. Calib's room, to be moved 
only at his discretion, or at that of a Level 4 Administrator. SCP-177 
is to be kept in a level-4 storage locker. During use of SCP-177, 
standard rules of chess must be adhered to; any test subject 
attempting to cheat or deviate from these rules is to be escorted 
from the room. 


Description: SCP-177 is an eight by eight square standard chess 
board measuring 40 cm by 40 cm. On the board are 16 pawns, two 
Kings, two Queens, four Bishops, four Knights, and four rooks, 
totaling 16 black and 16 white pieces. All items are carved out of 
elephant ivory. The white pieces are moveable, and can even be 
removed from the board with minimal force; the black pieces, 
however, cannot be removed from the board, or moved by any 
outside force; forces in excess of 3 kilo-newtons have been applied 
to the black pieces, only resulting in damaged equipment. 


When a legal opening move is made using the white pieces, 
SCP-177 enters an active state. When active, SCP-177 can be used 
to play a game of chess using standard rules (white moves first, 
pawns can move two squares on first move, etc.). The black pieces 
move autonomously, and after a move is made using the white 
pieces, that piece becomes immovable until black makes a move. 
When a piece is captured, it is moved off to the side of the board 
and removed from play automatically. In the case of the white side 
winning, the black pieces all return to their original positions, and no 
further effects are noted until a new game starts. If black should win, 
the black pieces do a celebratory "dance" and the white pieces fall 
down, before righting themselves to their original position. Should a 
stalemate occur, all pieces fall down and return to original positions. 


Addendum: History of SCP-177: SCP-177 was brought into 
Foundation custody 03/ /199 , following a routine sweep of antique 
stores in the area of London, England. The shop in question was 
found to be mundane, with the exception of SCP-177, which was 
acquired by Dr. Calib. The shop has since been under surveillance 
for any further anomalous activity. 


Partial Test Log: 


Test #: 001 

White Player: D-177-01, female, Caucasian, age 25. Subject 
chosen for her aptitude in chess. 

Results of Game: Heavy casualties on black side, ending in 
checkmate for black after 60 moves. 


Test #: 014 

White Player: D-177-01, same subject as previous 13 games. 
Results of Game: Few casualities on black side, ending ina 
resignation from D-177-01 at 50 turns; almost all white pieces were 
captured. This is the first recorded instance of SCP-177 actually 
winning a game. 


Test #: 025 

White Player: male, Chinese, age 34. Local chess 

champion in the town of [REDACTED], Jiangsu Province, PRC. Mr. 
was informed that SCP-177 was operated remotely by an 

advanced chess computer developed by Sherman Computer 

Products. 

Results of Game: SCP-177 successfully promoted one of its pawns 

to a queen, and used this piece to place Mr. _ into check several 

times before an eventual checkmate at 75 turns. Mr. 

administered amnestics and released. 


Test #: 051 

White Player: male, Japanese, age 50. Former Japanese 
National Chess champion. 

Results of Game: SCP-177 had considerably long pauses between 
turns (often in excess of 10 minutes), and moved pieces slowly. 
Eventually, Mr. resigned, declaring that the board was "Broken" 
and "Taking too damn long". In future tests, time control will be used 
to ensure there are no repeats of this test. Mr. administered 


amnestics and released. 


Test #: 167 

White Player: Dr. Calib, chess expert and head researcher on 
SCP-177. Dr. Calib requested to play a game with SCP-177. 
Results of Game: Checkmate for SCP-177 at 154 turns. Dr. Calib 
proclaimed that it was the "best damn game of chess [he] had ever 
played", and expressed interest in a rematch. 


Test #: 200 

White Player: "Deep Blue" chess computer 

Results of Game: SCP-177 narrowly lost to Deep Blue in 50 
moves. Since this time, SCP-177's chess strategy has been noted to 
be greatly improving. 


Test #: 406 

White Player: Dr. Calib 

Results of Game: Checkmate for Dr. Calib in 11 turns, a new 
record for SCP-177. Dr. Calib stated that SCP-177 "must have 
cheated", citing the misuse of the en passant move. Footage shows 
that SCP-177 played legitimately. 


Test #: 529 

White Player: ,20 World Chess Champion. Mr. was 
informed that SCP-177 was being controlled by an advanced chess 
computer developed by Sherman Computer Products. 

Results of Game: Mr. lost to SCP-177 in 90 moves, stating that 
"whoever programmed this computer was a genius". Mr. was 
administered Class-A amnestics following testing and released. 


Test #: 702 

White Player: "Rybka" Chess Computer, winner of 2007-2010 
World Chess Computer Championships. 

Results of Game: SCP-177 won in 25 moves. 


Test #: 975 

White Player: "Andersenn", a chess computer developed by Dr. 
Calib with the express purpose of beating SCP-177. Computer was 
built to be able to deviate from rules of chess and "cheat" if 
necessary. White pieces manipulated by robotic arm. 

Results of Game: Game progressed normally until turn 63, when 


Andersenn attempted to move the white queen in an L-shape similar 
to a knight in order to achieve check. Following this, SCP-177 was 
"thrown" at Andersenn by an unseen force at over km/h, resulting 
in the destruction of several vital circuits in the computer. 


New protocol. No cheating. Do | even need to say what would 
happen to a human if they cheated against this thing?! -Dr. Calib

SCP-178: "3-D" Specs 


Item #: SCP-178 
Object Class: Euclid 


Special Containment Procedures: SCP-178 is to be stored ina 
Class 3 Anomalous Object Container guarded by no fewer than two 
(2) armed personnel with Level 3 clearance when not undergoing 
testing. Item is to be removed from containment only with the written 
permission of personnel with Level 4 clearance or higher. Following 
Incident #178-14-Alpha all tests are to be monitored remotely 
and the presence of all personnel apart from test subjects in 
the testing area during experimentation is expressly prohibited. 


Description: SCP-178 is a pair of white stereoscopic (“3-D”) 
glasses with a rectangular white cardboard frame and lenses of 
transparent blue and red (left and right lenses, respectively) plastic. 
The item exhibits no unusual physical properties apart from a slight 
discoloration of the cardboard consistent with age. When worn, the 
wearer begins perceiving large bipedal entities in addition to its 
ordinary surroundings. Entities reportedly exhibit a docile and 
occasionally curious behavior (reports include entities leaning over 
the shoulder of persons working and observing them with interest), 
with one exception. Any attempt by the wearer or any other 
personnel (see Incident Report #178-14-Alpha) to directly interact 
with the entities results in severe lacerations suddenly appearing on 
persons involved. The appearance of lacerations is rapid and 
continues until the moment the wearer expires. The pattern of 
lacerations is always consistent with being slashed with three (3) 
parallel, tapered sharp objects of lengths varying between 14.2 and 
27.4 cm and maximum thickness varying between 2.9 and 8.1 cm. 
Recording and measuring devices used during testing failed to 
detect any anomalies, including while lacerations were appearing on 
subject(s). Subjects do not report hearing any sounds emanating 
from the entities. Long-term observation of subjects exposed to the 


item reveals no lasting effects. Stereoscopic images viewed through 
the item appear three-dimensional. 


Addendum #1: Item was recovered on / /19 in , Tennessee, 
by Agent [REDACTED], operating as deep cover agent in the U.S. 
Fish and Wildlife Service, who arrived in the town following reports 
ofa year old child being found dead in her second-floor bedroom 
apparently as a result of an unusual mauling. Agent [REDACTED] 
noticed a bloodstained stereoscopic image of a Ferris wheel 
adjacent to where the child was discovered, and after some 
searching, found the item under the child’s bed where it had 
apparently been thrown during the child’s death throes. Agent 
[REDACTED] then proceeded to call a recovery team to his location. 
Following the recovery team’s arrival, Agent [REDACTED] wore the 
item and looked at the image, reporting nothing unusual until he 
turned his head to his left, whereupon he noticed an entity 
approximately “an inch” from his face leaning over his shoulder and 
looking at the stereoscopic image. In the debriefing Agent 
[REDACTED] reported also noticing several other entities in the 
room observing him and the recovery team. Agent [REDACTED] 
refrained from attempting to interact with the entities and the item 
was recovered without incident. 


Addendum #2: All experiments are to be logged in file #1 78-E. 


Addendum #3: Personnel with Level 4 Clearance are urged to read 
Incident Report #178-14-Alpha. Reading Incident Report #178-14- 
Alpha is mandatory for all personnel with Level 4 Clearance or 
higher overseeing or approving experiments with the item. 
WARNING: Failure to comply with Addendum #3 is grounds for 
disciplinary measures.

File #178-E 


All experiments performed on SCP-178 are to be logged here. - 
Dr. 


Experiment 178-e-1 
Name: Dr. with Dr. and Dr. assisting. 
Date: / /19 


Procedure: D-class subject is to be placed in secured test chamber 
containing SCP-178. The test chamber is to be observed via 
bulletproof glass window to adjacent control room and via audio and 
video recording devices. D-class subject will be instructed to wear 
SCP-178 and report what it observes until told otherwise. 


Results: Subject D-17831 (Male, 41, no discernible mental 
abnormalities) is placed in the chamber and told to wear SCP-178. 
Subject is not told of SCP-178’s nature. Subject does as instructed, 
then immediately expresses distress by throwing SCP-178 away 
and covering its eyes while vocalizing fear. Research staff instructs 
subject to describe the source of its distress. Subject unresponsive. 
Research staff attempts to calm subject. Subject responds by 
uncovering its face and looking around, appearing to still be 
distressed. Research staff instructs the subject once again to 
describe the source of its distress. Subject responds by stating the 
presence of an unfamiliar entity in close proximity to its face the 
moment it wore SCP-178. Research staff instructs subject to 
describe the entity in detail. Subject responds by stating entity was 
“hideous” and “had too many eyes”. Research staff instructs subject 
to describe the entity in greater detail. Subject states it did not 
manage to perceive many details before removing SCP-178. 
Research staff instructs subject to wear SCP-178. Subject 
uncooperative. Research staff repeats instruction. Subject 
uncooperative. Research staff threatens subject with termination 


unless it cooperates. Subject uncooperative. Testing is ended and 
subject placed under surveillance to test for long-lasting symptoms 
of exposure. Subject displays symptoms of mild paranoia for two 
days before returning to normal behavioral patterns. Surveillance 
ended after thirty days and subject terminated. 


Note: Well, this wasn’t very informative but at least it confirms we 
have an actual anomalous object in our hands.
