Looking for the best multiplayer indie horror games on Steam in 2026? From chaotic co-op adventures to terrifying multiplayer encounters, these are Thrill Talkz’s top 10 picks.
Horror doesn’t always have to be experienced alone. Some of the best indie horror games become even more terrifying when playing with friends.
Multiplayer horror games just hit differently. Whether you’re working with a group of survivors or a deranged band of killers, communication, teamwork, and camaraderie can mean the difference between winning and losing.
Top 10 Multiplayer Indie Horror Games on Steam in 2026
1. R.E.P.O.
R.E.P.O. has quickly become one of the most popular co-op horror games on Steam. Developed by Swedish studio semiwork, the game combines physics-based gameplay with terrifying creatures and chaotic teamwork.
Players explore dangerous environments while searching for valuable objects to extract. The catch is that almost everything has physical weight, making even simple objects surprisingly difficult to transport.
Proximity voice chat makes communication particularly important. It only takes one player to panic, which can quickly spread through the entire team when a monster appears.
The combination of horror, comedy, physics, and unexpected encounters makes R.E.P.O. one of the most hilarious and addictive multiplayer indie horror experiences available.
2. Lethal Company
Zeekerss’ Lethal Company puts players in the role of employees collecting scrap from abandoned moons. Meeting the Company’s profit quota becomes increasingly difficult as players face dangerous creatures and navigate environmental hazards.
The game thrives on unpredictability. You can spend several minutes peacefully searching an abandoned facility before everything suddenly falls apart.
Communication also becomes essential when players split up. One person can guide teammates from the ship while others venture into hostile locations searching for valuable scrap.
Its blend of exploration, survival horror, and dark comedy has made Lethal Company one of the defining multiplayer indie horror games of recent years.
3. Phasmophobia
UK indie developer Kinetic Games are the brains behind Phasmophobia – a game where players transform into paranormal investigators tasked with identifying different types of ghosts.
Players must gather evidence using specialised equipment. This creates a slower experience where observation and communication matter more than combat.
The tension increases when the ghost becomes aggressive. Suddenly, the equipment that helped identify the entity becomes secondary to finding somewhere safe to hide.
For gamers who prefer slow-building atmospheric horror over frantic action, Phasmophobia remains one of the strongest multiplayer choices on Steam.
4. The Outlast Trials
The Outlast Trials brings the disturbing world of Red Barrel’s Outlast into a multiplayer survival-horror experience. Players take part in horrific experiments while attempting to complete objectives and escape.
Unlike traditional co-op games, working together doesn’t make the experience feel safe. Players must traverse creepy areas while avoiding enemies and handling finite resources.
The game’s grotesque environments and psychological themes create an oppressive atmosphere. Playing with friends can also make the experience extremely entertaining when stress kicks in. For more games that put psychological tension at the heart of horror, explore our guide to the Best Psychological Indie Horror Games on Steam in 2026.
For fans of extreme survival horror, The Outlast Trials offers one of the most polished multiplayer experiences in the genre.
5. Content Warning
Content Warning takes a more unusual approach to multiplayer horror. Players dive into the Old World to record terrifying encounters in an attempt to become famous online. This game was developed by a team of five independent developers known by their aliases: Wilnyl, Philip, thePetHen, Skog, and Zorro.
The result of their efforts is a chaotic blend of horror and comedy. One moment you’re creeping through the darkness; the next, your friends are screaming, panicking, and running for their lives.
The game’s physics and proximity-based chat make every expedition unpredictable and unique. It’s a delicate balance of risk versus reward – capturing quality footage becomes almost as important as surviving the creatures you meet.
For players who love multiplayer horror with a lighter tone, Content Warning offers something which stands out from traditional survival horror.
6. Escape the Backrooms
Escape the Backrooms brings the internet’s famous liminal horror concept into a multiplayer survival experience thanks to independent developer, Fancy Games (also known as Fancydev or Fancy).
Players must walk alien environments inspired by the Backrooms lore while solving puzzles and avoiding hostile entities. The unfamiliar surroundings create an unsettling sense of isolation despite playing alongside friends.
Getting separated from your group can make the experience particularly tense. Additionally, surroundings quickly become threatening when you realise something may be following you.
For fans of liminal spaces and atmospheric indie horror, Escape the Backrooms turns empty corridors into a waking nightmare. With eerie environments, unpredictable entities, and danger lurking around every corner, sticking close to your friends quickly becomes the best chance of making it out alive.

7. DEVOUR
DEVOUR throws up to four players into a series of supernatural survival scenarios. Developed by London-based indie studio Straight Back Games, each map presents a different possessed enemy that players must overcome while completing objectives.
The gameplay revolves around cooperation and resource management. Players must gather the key ritual items while avoiding increasingly aggressive cultists.
Things become progressively more chaotic as the session continues. What begins as a manageable objective can quickly turn into a desperate attempt to keep everyone alive.
DEVOUR is a great choice for players who enjoy fast-paced spooks and supernatural horror with friends.
8. SCP: Secret Laboratory
SCP: Secret Laboratory takes multiplayer horror in a completely different direction. Developed by Northwood Studios, players enter an underground SCP facility during a catastrophic containment breach.
Different players take on different roles, including scientists, security personnel, Class-D subjects, and SCP entities. Each role has different objectives, creating surprise scenarios throughout every match. Furthermore, the game’s reliance on player interactions makes every session different.
For fans of unpredictable multiplayer horror, SCP: Secret Laboratory offers an experience that traditional co-op games cannot easily replicate. It’s also completely free to play, making it a natural addition to our guide to the Best Free Indie Horror Games on Steam in 2026.

9. Murky Divers
Murky Divers takes multiplayer horror beneath the waves, throwing players into the depths to explore abandoned facilities and recover valuable research.
Developed by French indie studio Embers, players venture into the darkness from their submarine, searching wrecked locations while managing limited oxygen and watching for weird creatures lurking in the water. Communication becomes crucial when the team splits up to complete objectives.
The underwater setting gives the game a distinctive sense of claustrophobia. Murky water (hence the title!), tight corridors, and limited visibility make it difficult to know what’s in store beyond your flashlight.
For anyone craving something different from haunted houses and abandoned buildings, Murky Divers offers a tense and refreshingly deep take on multiplayer indie horror.
10. Pacify
Pacify throws players into haunted locations where they must investigate paranormal activity and complete rituals while avoiding terrifying entities. Developed by Shawn Hitchcock (creator of indie classic Emily Wants to Play), each scenario introduces a different supernatural threat, with players working together to uncover what happened and find a way to escape.
The gameplay revolves around collecting items, solving objectives, and managing increasingly aggressive enemies. What starts as a relatively controlled investigation can turn into chaos as the entity becomes faster and more dangerous.
Playing with friends adds another layer of tension. Splitting up can help complete objectives faster, but wandering away from the group leaves you vulnerable when the haunting takes a turn for the worse.
Pacify remains a straightforward multiplayer horror experience that’s easy to jump into with friends. If you prefer horror that delivers its scares without demanding a lengthy commitment, check out our guide to the Best Short Indie Horror Games Under 2 Hours.
