SCP artifacts pose a significant threat to global security. Various agencies from around the world operate to maintain human independence from extra-terrestrial, extra-dimensional, and extra-universal threat. In the past humankind has been at the whim of these bizarre artifacts and similar phenomena, but we have now reached a point in history where we can begin to control and contain these defiances of natural law.
You are now working for the SCP Foundation. You have no need to understand how or why we operate. What you do need to understand is how vital your mission is.http://scp-wiki.wikidot.com/mainhttp://scp-wiki.wikidot.com/scp-series
Secure. Contain. Protect.
That is all.
[Not a game, but one that could be an excellent source for a horror setting.]
