10 Awesome Video Game Villains You Never See

In the case of Lisa from PT, it's less about the terror players are able to see, and more about the sinister presence they don't.

The playable teaser for the doomed Silent Hills, the game is one of the most terrifying psychological experiences any gamer can ask for.

In P.T., players take control of an unnamed protagonist who wakes up in a house that had been the scene of a familicide. Lisa is the wife of the murderer and consistently appears haunting players in the never-ending loop of corridors in the house.

However, thanks to the discovery of a specific camera hack, this half-rotten corpse is given a seriously sinister extra dimension. The camera hack is used to unsettle players by having Lisa's noises appear to be right behind their ears; what players might not have realised is that all throughout the game, Lisa is stood right behind them wherever they go.

P.T. has gained something of a mythical status on the back of its cancellation and pulling from the PlayStation Store and for the terrors Lisa supplies. The revelation that she is always present, watching and following without being seen, only makes gives this terrifying title another layer of chills.
