The cell of SCP-173. If you wan't 173, download a mod (3 mods available I think). If you have problem with the system, please change of version (1.11.2) ;)
Some words on SCPF :
SCPF is the foundation of Special Containment Procedures. This foundation "stores" (or contains if you wish) all the abnormalities (animals) in cells.These cells are placed in "area" or "site" each with its own SCP. SCP is classified into three parts: SAFE (such as SCP-999 or SCP-914), EUCLID (all those not yet diagnosed by scientists such as SCP-079), and KETER (those that are dangerous such as SCP-106).
