SCP Invalidation is a first-person independent survival horror game developed by Joonas (Regalis) Rikkonen, and its creation is based on SCPWiki. The game tells the story of D-934 1 (a D-level researcher, originally a fifth-level researcher, was downgraded by the Foundation's cross-level research because of one of the proposals of SCP-00 1), which was forced to escape from the facility for survival when the facility could not accommodate it.
