Doki Doki Literature Club (DDLC) is a free-to-play horror game, despite how adorable it looks. Its deceptive looks are part of what makes this game scary, since visual novel games tend to be exclusively dating sims, but not DDLC.

This anime-style game is layered with secrets and terror, even within the game files themselves. At various points throughout the story, new files will appear. These would be things such as cryptic messages, creepy images, references and foreshadowing.

At the end of the game, in order to defeat the game's main antagonist, the player is required to go into the files and literally delete the character. The story cannot progress otherwise.

It's a unique way to utilise game files, and also introduce new fears to perceptive players: more than likely, the fear of their own computer.

When Alien: Isolation came out, it was immediately revolutionary for its enemy A.I., which remains among the best in gaming. So, of course, this brings an entirely new air of excitement to what the recently-announced sequel might bring.

The Xenomorph A.I. seems complex, but it's actually quite simple. It's run by two entities, one that knows where the player is at all times, and one that doesn't know.

The entity that doesn't know is the one searching and managing the Xenomorph's actions; meanwhile, the entity that knows is feeding hints about the player's location. Not to mention, the Xenomorph learns from the player's actions in and out of combat.

Players have to learn to outsmart the Xenomorph's mechanics, living up to the Ripley family name. An adapting A.I. forces players to counter-adapt, combined with the looming fear of being hunted, it's a terrifying experience overall.

The radio in Silent Hill is a series staple, originating from the first game back in 1999, to the point where other horror games don't really replicate it.

The radio is broken, and mostly silent, except when players wander near a monster. Then, it'll start crackling, ringing, or glitching depending on the game — either way, it's alerting the player an enemy is nearby.

10 Scariest Games Set in Space, Ranked

The vastness of space is terrifying yet enthralling. Here are some games that are living proof of this.

Of course, it doesn't stop there. The series incorporates several different scares regarding the radio, either in cutscenes or in actual gameplay.

The recent release of the Silent Hill 2 Remake also introduced a new trophy, Radio Silence. This is awarded to players who go through the entire game without using the radio (which is done by immediately turning it off upon getting it). Diminishing the only alarm system players have brings out entirely new terror on its own.

Haunting Ground is a cult-classic survival horror game released by Capcom in 2005. The game follows the protagonist Fiona and a white German Shepherd named Hewie trying to escape the terrifying Belli Castle.

This PS2 horror game introduced him not only as a companion to the story, but a companion in the gameplay as well.

Fiona is able to give Hewie commands, and he'll follow through with each one as best as he can. Afterwards, she'll be able to provide praise or scold him, which he will learn from and adapt to.

He will help with searching rooms, dealing damage and even guarding Fiona. As long as players put in the effort to train their dog, he'll be the very best boy.

The first rule in any survival horror game tends to focus on one key thing: shoot the enemy in the head. This is a constant in the horror genre to where it's expected, a safety net to know that the enemy is dead and will stay as such.

Dead Space subverted many players' expectations by ripping that safety net advice away. Cutting off the head doesn't do anything to the Necromorphs, the monsters on the ship.

If anything, they start running and flailing around like a chicken with their head cut off, causing more damage and destruction. In order to survive, players have to cut off their limbs.

This sci-fi horror game completely flipped players' expectations, enough to where veteran and beginner players will be challenged.

Siren (also called Forbidden Siren in other parts of the world, specifically in the PAL Region) is a tough and terrifying game from the PlayStation 2 era.

While the combat itself is challenging, other elements of the gameplay are particularly unique. One mechanic in particular is the Sight Jacking ability.

10 Underrated Indie Horror Gems

As Halloween draws closer, it's a great time to explore underrated horror gems, including games. Here are some indie games that could use more love.

Sight Jacking allows the player to see through another character's eyes, which will reveal hidden details and clues that would otherwise not be found. This also assists in plotting the path ahead, which is crucial for surviving the game's world.

It's a unique perspective, no pun intended, into Siren's world and into the genre of horror as a whole.

The fear of going insane is a concept explored in many psychological horror games, but none have explored it quite like Eternal Darkness: Sanity's Requiem.

This game is notorious for its fourth wall breaks, messing with the player directly rather than the protagonist, Alex. However, it was also the first game to feature a Sanity Meter.

The Sanity Meter is directly influenced by what Alex witnesses and has to deal with, and if this meter gets too full, she'll begin to hallucinate. These hallucinations vary, but are all horrifying depending on how filled the meter is.

Other games, such as the Amnesia series, have incorporated the concept of a Sanity Meter into their games, directly influenced by what Eternal Darkness had done years ago.

The biggest surprise of Alan Wake is how it tackles the concept of darkness and light, most specifically regarding the use of the flashlight. This Microsoft-exclusive horror game asks a simple question: what's a better way to get rid of darkness than pure light?

Throughout the game, the titular protagonist, Alan, must shine his flashlight onto enemies before he can attack them. By dispelling the darkness that consumes them, it allows them to be vulnerable to damage. Otherwise, bullets won't hurt them.

With the enemies using literal darkness as a covering shield, the flashlight becomes far more important than just a means of vision.

There isn't a horror fan alive that hasn't heard of Five Nights at Freddy's (FNAF) at this point. This was an indie horror game that exploded exponentially in popularity, especially with the release of the live-action movie.

However, when the game came a decade ago, it introduced a new concept that indie games still try to replicate to this day: managing the in-game security cameras.

10 Best Games Like Silent Hill

Fans of Silent Hill tend to be hungry for more horrifying games similar in style — maybe with the fog not included.

The cameras are connected to the building's power system, which players also have to manage if they want to survive. Prior to this, no game had done anything quite like it before — to the point where series creator Scott Cawthon is continuously praised for his ambition.

By confining the player to an office, the only thing they can manage is their power usage and helplessly watching the cameras, the fear heightens tenfold. The jump scares can get frustrating in harder difficulties (especially in the notorious 20/20/20/20 Mode), but the tension remains all throughout each night.

When players are asked about horror games with unique mechanics, Fatal Frame is almost always mentioned. Known as Project Zero in Europe, this horrifying PS2 ghost story is practically a staple in Japanese horror that leaves players itching for more.

The combat stems from the Camera Obscura, a magical camera that can exorcise restless spirits with each picture. So, this means that in order to defeat the ghosts in this game, players have to face them head-on (who would have thought taking pictures would feel so vulnerable?).

It doesn't stop there, though, because the camera has to take a few moments to recharge between photos. Players have to time their movements and photos carefully, as it could literally mean life or death otherwise.

It became a staple in the Fatal Frame franchise, with new and unspeakable horrors in every snapped picture.
