20 Most Terrifying Enemies In Video Game History

4. Lisa - P.T.

When you get right down to it, this whole demo/teaser is basically just one big greatest hits reel of vignettes that exists only to rob you of sleep for the rest of your days.

If the continually looping house isn't enough to upset your equilibrium and violently murder your sanity, each iteration piles on more and more layers of spookiness in ways both subtle and obvious. The lights flicker out, sounds of questionable origin travel through the hallways; before you can even come to grips with the situation there's a deformed fetus in the sink.

And that's just foreplay, the main event hasn't even started yet.

As the increasingly horrific stream of news continues spilling out of the radio, the mention of a man's brutal murder of his wife becomes especially relevant as you suddenly realize her ghost is in the house with you. Everywhere you turn, she's there - peeking through doorways, floating outside of windows, peering down from balconies; it's impossible to predict her movements, but she makes it no secret she's after you.

Silent Hills may be no more, but Lisa will haunt gamers for generations.
