Halloween is the perfect excuse to intentionally freak yourself out, but you might want to leave the lights on for these games.

Although the gaming world has contributed immensely to the horror genre, some titles stand out as "particularly scary." Here are 5 video games that definitely earn that title.

1. Slender: The Eight Pages

Highly regarded as one of the games that made Slender Man so popular (and terrifying), Slender: The Eight Pages contains just the right mix of atmospheric unease and actual danger to keep your heart continually pounding.

2. Amnesia: The Dark Descent

Exploring a dimly lit castle in the 1800's would be terrifying enough, especially without a gruesome monster chasing you. Plus, the protagonist (you) suffers from amnesia, leaving the plot scattered about in notes you've written previously. As you hunt your past, something else hunts you.

3. SCP Containment Breach

This game takes place in a lab designed to study a rather peculiar life form that can only move when it is not being looked at. SCP (Secure. Contain. Protect.) Containment Breach features a careful balance of avoiding the monster while also trying to keep a watchful eye on it.

4. Alien: Isolation

For fans of the Alien franchise and/or sci-fi/horror games, Alien: Isolation is a must. Playing as Amanda Ripley (daughter of famous Alien character Ellen Ripley), players must survive through a mission gone awry. Alien: Isolation features a great mix of problem solving, fighting, and of course, frantically hiding from the franchise's most infamous villain.

5. Five Nights at Freddy's

This list would not be complete without mentioning one of the most famous horror games in recent history. Five Nights at Freddy's focuses on you, a night security guard for a Chuck E Cheese's look-alike. While watching the empty building could be creepy on its own, the animatronics are also allowed to free-roam at night. Of course, if they catch you, you're done for. As the nights progress, the plot thickens, and the terror rises.
