Project P.T. is a new interactive horror game from 7780s Studio. It was announced during Sony press briefing and a demo is available if you dare trying it. Update 2: P.T. stands for Playable Teaser and is indeed a teaser for a new Silent Hill by Hideo Kojima and Guillermo del Toro, starring Norman Reedus.
