It is the fantasy product of scp Foundation. It is made of concrete and steel, and contains traces of Krylon brand paintings. SCP- 173 is mobile and hostile, but it can't move under direct vision. The line of sight with SCP- 173 must not be interrupted at any time, and the personnel in the container must give instructions before blinking.

By the way, scp has many fantasy products. You can type a scp-xxx (three digits) at will.

If you are looking for a game, it is SCP- 173 SCP-087 scp432.
