 Item number SCP-176 Object Class Euclid Special Containment Procedures SCP-176 is contained on site under the cover of industrial chemical contamination. Any civilians attempting to enter SCP-176 must be detained. Multiple high-speed cameras are set up within the observation room and linked to continuously running analysis computers. If any deviation is observed in the recorded sequence, all recorded data must be immediately backed up and senior staff notified. Description SCP-176 is an abandoned chemical factory situated near ████████. The building consists of a factory floor and an observation room on the second floor, separated from the main room by one-way mirrors. There are three entrances to the building. A three-bay loading dock, whose doors have been welded shut. A ground floor employee entrance. A second floor observation room entrance, accessible via a metal staircase in the north end of the building. When the main building is entered via the loading dock or employee entrance, no anomalies are observed. Nearly an empty room and severed is used in this repair, with a small amount of metallic debris consistent with a stripped down abandoned factory. The inside staircase leading up to the observation room is missing and inaccessible, and so far every attempt to enter the observation room via the inside of the factory through the accessed door or windows has failed. When the observation room is entered via the second floor outside door, a factory observation room consistent in disuse and disrepair to the rest of the building is found. However, when the factory floor is viewed through the observation room windows, the anomalous property of SCP-176 is visible. 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 of white clean suits appear to be working on the device. Approximately 5.9 seconds into the scene, the employee entrance door burst open, and four individuals wearing black tactical armor with no identifying marks or emblems entered 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 on 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 door or window from within the observation room are met with resistance inconsistent with the suggestive strength of the materials comprised in 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 announces of individuals in SCP-176. This is yielded to following information regarding the individuals visible in the scene. Unidentified Researcher No. 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 No. 2 Male Asian, approximately 35 years of age, with black hair and brown eyes, stands to the left of Researcher No. 1, carries a clipboard of an indecipherable writing on a notepad. Hit once in right shoulder at 8 seconds before dropping to the floor, out of sight behind the device. Unidentified Researcher No. 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 No. 4 Male Caucasian, approximately 45 years of age, with brown hair and indeterminate eyes, stands in front of the device to the northeast with its back to the observation room, shot twice in the head at 7.2 seconds, killed instantly. Unidentified Researcher No. 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 No. 1 Male, indeterminate, wielding a suppressed M4-A1, enters first, shoots Researcher No. 4 and Researcher No. 5, then moves towards the device. Unidentified Assailant No. 2 Male, indeterminate, wielding a suppressed MP5-N, enters second, turns left and shoots Researcher No. 1 and Researcher No. 2, then sweeps towards the southeast. Unidentified Assailant No. 3 Male, indeterminate, wielding a suppressed MP5-N, enters third, turns right and moves under the observation room. Unidentified Assailant No. 4 Male, indeterminate, wielding a suppressed TMP, stays at the door, covering the others.
