Now Ive played a lot of horror games in my short life on this planet so far and have never really been frightened by them. I amnesia was one of very few that actually was scary, its no more than a joke to me now coz a while back I found the most frighteningly horrible bone melting horror game out their, a little project called SCP - Containment Breach. Anyone who spends a lot of time on /x/ will be well aware of http://www.scp-wiki.net And some of the scp series. But you dont really need to know anything.
Just download and and "enjoy"
