Horror games worth playing with friends

Being scared on your own is one thing. Being scared while someone screams down voice chat and abandons you in a corridor is a different game entirely. These are the co-op horror games players actually rated well, rather than the ones that got streamed hard for a week and then went quiet.

The 3D catalog: game boxes on wooden shelves, with the cat sitting at the counter next to its greeting.

The catalog in 3D

The same catalog has a room you can walk around in. The cat behind the counter is the AI Catbot, and they pick real games from it when you tell them what you feel like playing. Nothing is for sale, here or in there. They work from the whole catalog, not just this list.

Look around the 3D catalog

Lethal Company cover

A frantic, team-driven scramble through eerie moons where humor and dread collide as you race against a quota while scavenging for scrap.

Players say: Players say the game delivers hilarious and memorable co-op experiences that balance horror with comedy. It gets repetitive over time, and public lobbies are a gamble, but the regular updates and mod support keep it fresh. Solo play is challenging but rewarding.

Cube Escape: Paradox cover

4.8 of 5 from 11,984 players · free · Windows, macOS

A tense and atmospheric puzzle escape game that feels like a surreal, mind-bending detective mystery.

Players say: Players praise the creative puzzles and unique short film integration. Some find the logic inconsistent, with a few puzzles feeling like trial-and-error. The game is short and free for chapter one, but chapter two is paid.

TraumaCore Violence cover

4.9 of 5 from 162 players · Windows

A hyper-fast, snappy 2D fighter that feels like a frantic, surreal descent through darkly psychedelic combat.

Players say: Players praise the fast and fluid combat with a lot of depth, calling it the standout feature. The game is short but has good replay value, and its story and artstyle also get positive mentions.

Cryptid Farm cover

4.9 of 5 from 190 players · Windows

A tense farming sim where you tend crops while trying to survive mysterious and surreal horrors with friends.

Left 4 Dead cover

4.8 of 5 from 67,469 players

A frantic co-op survival shooter where teamwork is essential against relentless zombie hordes and special mutants.

Players say: Players call Left 4 Dead a classic cooperative zombie shooter that holds up well, though its content feels sparse compared to the sequel and the single-player bot AI is frustrating. The AI Director keeps each run unpredictable, making it a game players return to with friends.

Fursan al-Aqsa: The Knights of the Al-Aqsa Mosque cover

Fursan al-Aqsa: The Knights of the Al-Aqsa Mosque (2022)

4.8 of 5 from 1,017 players

A realistic, tense first-person shooter where tactical stealth and team coordination define the slow-paced war experience.

Players say: Players applaud the game as a fun throwback shooter with Max Payne-style action, though most reviews focus on its political stance rather than gameplay. Some note difficulty spikes with drones and tanks in the remake.

R.E.P.O. cover

R.E.P.O. (2025)

4.8 of 5 from 410,092 players · Windows

A tense, physics-driven co-op horror where you quietly haul fragile loot through haunted ruins, balancing slapstick chaos with the threat of instant death.

Players say: Players say the co-op horror is a blast with friends, mixing hilarious physics-based chaos with genuine tension. The game gets noticeably harder around level 10, and while updates are frequent, it still lacks official Chinese localization.

B.A.N.K. cover

B.A.N.K. (2025)

4.9 of 5 from 66 players · Windows

A chaotic cooperative simulator where humorous absurdity mingles with unsettling horror as you serve bizarre clients under pressure.

Players say: Players split on B.A.N.K. The core is a Papers, Please-like bank sim with a dose of horror, offering co-op and some funny moments, but many find the single-player loop repetitive and the negotiation system shallow. The game is short, around 5-6 hours, and reviewers note it feels rough around the edges, with some bugs in multiplayer.

DEATH IN UNISON cover

DEATH IN UNISON (2024)

4.8 of 5 from 750 players · Windows

You and a partner rely solely on walkie-talkies to navigate a twisted prison full of supernaturally dangerous criminals, making every moment a test of coordinated survival.

Players say: Players recommend the co-op horror game, comparing it to FNAF and praising its challenging but fair enemies and interesting story. However, they consistently report performance issues like poor optimization, long boot times, and problems when tabbing out, even on capable hardware.

Obscure cover

Obscure (2014)

4.8 of 5 from 3,201 players · Windows

You play as a group of high school students trying to survive a night of terror in a creepy school, with a classic survival-horror feel that leans on tension and cooperation rather than fast-paced action.

Players say: Players praise Obscure as a short, co-op survival horror that captures the feel of 2000s teen horror movies and classic PS2-era games. Many note the fixed camera angles and clunky controls, but say the cooperative tension and nostalgic atmosphere make it worth playing, especially with a friend.

Killing Floor cover

Killing Floor (2009)

4.8 of 5 from 68,770 players

Frantically surviving with friends against waves of grotesque creatures, where dark humour and teamwork keep the tension from becoming overwhelming.

Players say: Players call Killing Floor the best of the series for its grimy atmosphere and satisfying Zed Time bullet-time, but warn that finding matches is tough and the multiplayer setup is a slog. Opinions split on difficulty: some love the challenge while others find it punishing, especially Fleshpounds on higher waves.

Shipwrecked 64 cover

Shipwrecked 64 (2024)

4.8 of 5 from 2,619 players · Windows

An unsettling psychological horror that feels like a nostalgic kids' game twisted into something deeply wrong.

Players say: Players praise the early hours as a genuinely creepy and well-crafted ARG with a strong retro 64 aesthetic, but many warn the later layers become a tedious grind of chase sequences and obscure puzzles that quickly require a guide.

Don't Starve Together cover

Don't Starve Together (2016)

4.8 of 5 from 538,924 players · Windows, macOS, Linux

A grim cooperative struggle against a hostile, bizarre world where every resource and alliance matters to stave off starvation and madness.

Players say: Players say the game has an extremely steep learning curve with no tutorial, forcing beginners to rely on external wikis. Dying repeatedly to hunger, cold, darkness, or monsters is the core loop. The game shines in co-op, but losing a long world to a misclick or forgetting to pause can feel devastating. Players split on whether the difficulty is rewarding or off-putting.

Nekomew's Nightmares cover

Nekomew's Nightmares (2022)

4.9 of 5 from 53 players · Windows

A rhythm-action game where you dodge cartoonish monsters to a beat, blending cute visuals with spooky themes and cooperative play.

Players say: Players praise this rhythm horror game for balancing jump scares with forgiving miss timers. Many say it has a deep story about Nekomew's past traumas and compared its difficulty range from easy to hardcore, especially in guide‑less challenge mode. Some note occasional bugs, and a few call it short.

Granny: Chapter Two cover

Granny: Chapter Two (2019)

4.8 of 5 from 2,087 players · Windows

A tense game of silent cat-and-mouse where you creep through a dark house, hiding from two relentless pursuers while solving puzzles to escape.

Players say: Players say it improves on the first game with two antagonists and more features. It runs well on low-end PCs and has mod support on Game Jolt. Some find it buggy, and opinions split on how scary it is.

Escape From Mandrillia: Local Asymmetric VR vs PC cover

Escape From Mandrillia: Local Asymmetric VR vs PC (2022)

4.8 of 5 from 192 players · Windows

A tense game of cat-and-mouse where one player sneaks and fights as an outmatched robot while others hunt as aggressive alien monkeys.

Blood Typers cover

4.8 of 5 from 1,042 players · Windows

A frantic typing-based survival horror where you frantically type commands to fight, manage items, and escape a procedurally warping nightmare.

Players say: Players call it a smart mix of survival horror and typing practice, comparing it to Resident Evil and The Typing of the Dead. It rewards tactical target choice in co-op and has procedurally generated maps, though it does not support controllers and horde mode can overwhelm. Several players wish they had friends to play with.

Species: Unknown cover

Species: Unknown (2025)

4.7 of 5 from 10,029 players · Windows

You explore an abandoned spaceship as a mercenary hunted by an unknown entity, creating a tense atmosphere of survival and danger.

Players say: Players praise the co-op horror experience, calling it a fun blend of Alien Isolation and Phasmophobia. There is broad agreement that the game is currently limited to a single map, though multiple creature types and mission modes add variety. Some players report a frustrating EOS error that requires troubleshooting.

Transmissions: Element 120 cover

Transmissions: Element 120 (2016)
