Item #: SCP-XXXX

Object Class: Safe

Special Containment Procedures: SCP-XXXX is to be stored on a USB flash drive, kept in a standard Safe-class storage locker at Site-64 at all times. A computer running any Source Engine game is to be made available on-site for testing by personnel of Level 3-XXXX security clearance or above. All compiled .bsp files produced as a result of SCP-XXXX testing are to be stored on a seperate USB flash drive, available by request from Dr. ████. Following the results of Test Series XXXX-C, testing on SCP-XXXX has been suspended until further notice.

Description: SCP-XXXX consists of a single ███kb Valve Map File1, last modified ██/██/200█, named "compgridA.vmf". When opened in the Hammer editor2, the contents of SCP-XXXX consist of the following:

  • A 1024x1024 HU3 floorspace consisting of 256 square tiles, each tile measuring 64x64 HU, all tiles alternately textured gray and silver (similar to a chess or checkers board)
  • Four walls and a ceiling, all textured orange
  • 1x info_player_start (a standard entity used to denote the starting position of the player character)
  • 5x light_spot (a standard entity used to generate conical lighting within the 3D game space)
  • 1x logic_auto (a standard entity that fires a user-specified input/output chain as soon as the compiled map loads)
  • 4x logic_██████ (superficially similar to logic_auto, but with several major differences; entity is not recognised within any Source engine game's software development kit)
  • [REDACTED]

For a full analysis of SCP-XXXX's components, as well as compile logs and a full transcription of the input and output chains specified in the logic entities, please refer to Document XXXX-S10.

SCP-XXXX can be compiled and loaded as a Binary Space Partitioning file, or .bsp, in any compatible Source engine game. If SCP-XXXX is unaltered, or if any component apart from the texturing of the floorspace is modified, the .bsp will compile and run normally. However, SCP-XXXX's anomalous properties manifest when the pattern of gray and silver textures on the floor is modified before compiling. The compiled .bsp will instead display a new floor pattern; testing has lent credence to the theory that these new patterns are direct communicative responses to those specified beforehand in the Hammer editor.

It should be noted that compiled .bsp files display no other anomalous properties, apart from the aforementioned discrepancy between the uncompiled and compiled floor patterns. For this reason, designation of compiled .bsps as instances of SCP-XXXX-X has been deemed unnecessary.

SCP-XXXX was acquired on 03/19/2011 after Jared █████, a user on the █████████ gaming forum, made several posts describing his recent download of a "talking map". Foundation agents embedded in the forum's moderator team initially suspected that Mr. █████ was describing a rogue instance of SCP-████, but communications with the user later suggested the presence of a different anomaly. Agents stationed near Mr. █████'s home in Amersham, England, were able to seize his hard drive under the pretext of a police raid. Both interrogation of Mr. █████ and ongoing analysis of his hard drive have failed to ascertain SCP-XXXX's origin.

As of 6/04/2011, three series of tests on SCP-XXXX have been undertaken by Foundation staff; logs for all three series are presented below.
