18 Best Survival Horror Video Games Of All Time

3. P.T.

It may be a tech demo - a cancelled one at that - and it may all be over in under an hour, but I defy anyone who's played the mighty, potential-filled P.T. to deny its effectiveness at being outright terrifying.

Set in a repeating L-shaped corridor where a number of subtle environmental clues, potential enemies or clues as to what's happening change, P.T. is on its way to becoming a bonafide gaming legend. Being Konami cancelled Silent Hills and removed it from the PlayStation Store in the end, this Hideo Kojima/Guillermo del Toro collaboration can only live on in the hard drives of those who downloaded and kept it at the time.

As such, its various unlockable details and bone-chilling scares can only be experienced if you really do your research, helping add to the mysticism of this once-beautiful project that shall never be.
