SCP-XXXX
Description: SCP-XXXX is the Stone Mountain Tennis Center1, situated in Stone Mountain, GA, United States.
Its primary anomalous property is the spontaneous dissipation of all sound upon entry, with all preliminary acoustic experiments indicating the equilibration to 0dB through unknown means. Video footages filmed within SCP-XXXX are also affected. Traveling further into SCP-XXXX is SCP-XXXX-1.
SCP-XXXX-1 is a tennis stadium with a seating capacity of 12000. Under the spectator seats, an indeterminate number of human corpses is present (hereby designated as SCP-XXXX-ℇ). Most instances wear attires generally fitting in the late 20th century.
At random periods of time, SCP-XXXX-ℇ reanimates and climbs up onto the seats. Two SCP-XXXX-ℇ instances, dressed in sportswear and with a racket in hand, walk to a hard court situated at the center of SCP-XXXX-1 to play a match of tennis, designated as Event Alpha.
Addendum XXXX-1 (Discovery): A consistent trend of missing person reports arose during the three months prior to SCP-XXXX's decommissioning, prompting Foundation intervention. On 03/09/2006, MTF Delta-5 ("Tennis Hooligans") was deployed, after which all communications were lost. The following is the transcript of the event.
Video Log
MTF Delta-5 ("Tennis Hooligans")
Due to SCP-XXXX's anomalous property, no sound was recorded throughout the entire length of the video. POV is from the Squad Leader of MTF Delta-5.
Squad Leader produces several hand gestures, after which four other operatives nod and proceed to traverse further through SCP-XXXX, weapons ready.
At the entrance of SCP-XXXX-1, a wooden sign reads: "PLEASE RESPECT OUR PLAYERS: DON'T BE NOISY". MTF Delta-5 enters SCP-XXXX-1 during an ongoing Event Alpha. Squad Leader raises his hand to the side of his head and presumably attempts to regain contact with Site Command. Squad Leader faces the other operatives in apparent confusion.
The operatives attempt to reach Site Command but fail. Squad Leader turns to face the interior of SCP-XXXX-1. All SCP-XXXX-ℇ instances turn to stare at MTF Delta-5 at the same time. Most are missing several limbs and other body parts, with the common observation being a large wound on their throats.
Squad Leader gestures to the other operatives, who turn to look at the SCP-XXXX-ℇ instances. No movement for several seconds until an instance stands up slowly.
MTF Delta-5 trains their sights on the SCP-XXXX-ℇ instance. Soon, other instances follow suit. Squad Leader gestures to retreat without sudden movement.
Four seconds later, all SCP-XXXX-ℇ instances run down the seats, falling onto the court. Most recover from the fall and proceed to run towards MTF Delta-5. Squad Leader gestures to engage. Several SCP-XXXX-ℇ instances stagger after being shot, before collapsing. More instances climb over the bodies, eventually overwhelming MTF Delta-5.
Squad Leader glances at the other operatives, who are pinned to the ground by the SCP-XXXX-ℇ instances, proceeding to dislodge their limbs. An SCP-XXXX-ℇ instance uses its fingers to pierce the operatives' throats, before widening the wound with their hands and consuming the internal appendages.
Squad Leader continues to engage. The two players frown at the Squad Leader, and proceed to toss a tennis ball before hitting it with their racket. The tennis balls miss the camera by a few centimeters before producing a heavy thud. A wet gurgle is heard behind the camera and Squad Leader collapses. The camera shudders as the Squad Leader frantically shakes his head. An SCP-XXXX-ℇ instance approaches Squad Leader, opening its mouth to consume the camera. The feed ends.
Shortly after losing contact with MTF Delta-5, a drone was deployed. Captured images show that the entrance of SCP-XXXX-1 is covered with a red liquid. Footprints lead into SCP-XXXX-1, where Event Alpha is ongoing. MTF Delta-5 operatives are seen seated with other SCP-XXXX-ℇ instances, spectating the event with several limbs missing. A hole is seen on the Squad Leader's throat.
Containment Procedures are to be continuously enforced until SCP-XXXX's demolishment.
