Eurogamer’s announcement of Star Trek: Shadow Frontier from the Bloober Team revived a question that gets asked every year: what are the best sci-fi horror games on PC right now? The genre lives in the gap between System Shock and Alien: Isolation, and 2025 finally added Signalis-class indies to the catalog. We ran seven of the most-recommended titles through fresh playthroughs, ranking on sustained dread, set-piece restraint, save-system fairness, and how well each one holds up on modern hardware.
What to look for in a sci-fi horror game
- Combat vs evasion. Dead Space and System Shock let you fight back. Alien: Isolation and SOMA mostly don’t.
- Story payoff. SOMA and Signalis trade jump scares for thematic dread; both end on big ideas.
- Performance on modern GPUs. All seven run on modern PCs; only the older two need community patches for ultra-wide displays.
- Steam Deck friendliness. All seven have Verified or Playable status; SOMA and Signalis are the cleanest fits.
- Length. Signalis is six hours; Prey can stretch past 30. Plan your evening accordingly.

The 7 best sci-fi horror games for desktop in 2026
1. Dead Space — Best modern remake
Dead Space (the 2023 EA Motive remake) is the genre’s most polished current entry. The USG Ishimura is rebuilt as a single uninterrupted starship, Isaac speaks now, and the necromorph dismemberment system finally feels like it should have a decade ago. The Plasma Cutter still kills things and the sound design still wins awards.
Where it falls short: Hardcore fans of the 2008 original have legitimate beefs with some pacing changes. Some encounters scripted in the original are now ambient, which dilutes a couple of standout moments. Mouse-aim feels twitchy until you tune sensitivity.
Pricing:
- Free: no
- Paid: $59.99 base, often $20 on sale
- Platforms: Windows
Download: Dead Space on Steam
Bottom line: Start here if you’ve never played the series or you haven’t replayed it since 2008.
2. Alien: Isolation — Best for pure dread
Alien: Isolation is still the gold standard for adaptive AI horror. The Xenomorph learns from your tactics, hides in vents, and refuses to follow scripted patterns. Sevastopol station’s design rewards exploration and punishes carelessness. Creative Assembly’s commitment to the 1979 film’s aesthetic is unmatched.
Where it falls short: Length is brutal at 18 to 22 hours; second-half pacing drags. The Working Joes synthetics can feel cheap in tight corridors. Some chapters force pure stealth in a way that conflicts with the open-ended start.
Pricing:
- Free: no
- Paid: $39.99 base, often $7 on sale; Season Pass adds standalone DLC
- Platforms: Windows, macOS, Linux
Download: Alien: Isolation on Steam
Bottom line: The genre’s peak for tension. Set aside three or four sessions; it’s not a weekend game.
3. SOMA — Best story-first horror
SOMA is Frictional Games’ philosophical horror about identity, consciousness, and the question of what makes a person. PATHOS-II, the underwater research station, is one of the best-realized settings in the genre. The 2017 Safe Mode update lets you experience the story without combat encounters if you want.
Where it falls short: Some monster chases feel obligatory and break the meditative pace. The ending lands hard but only on a first playthrough. Save points are sparse in some chapters.
Pricing:
- Free: no
- Paid: $29.99 base, often $6 on sale
- Platforms: Windows, macOS, Linux
Download: SOMA on Steam
Bottom line: Best pick when you want existential dread that sticks with you for weeks.
4. Prey — Best immersive sim horror
Prey (Arkane’s 2017 sci-fi horror, not the 2006 shooter) puts you on Talos I station against shape-shifting Typhon. Build paths range from melee-heavy to psychic-powers to silent stealth, and the station permits backtracking in a way that rewards remembering what you saw earlier. The Mooncrash DLC adds a roguelike survival mode on top.
Where it falls short: First-hour pacing is slow; some players bounce before the systems open up. The Mimic enemy is a great gimmick that wears thin in act three. Bethesda’s launch had performance issues that took patches to settle.
Pricing:
- Free: no
- Paid: $29.99 base, often $7 on sale; Mooncrash DLC is $19.99
- Platforms: Windows
Download: Prey on Steam
Bottom line: Pick this when you want sci-fi horror that respects your problem-solving more than your reflexes.
5. System Shock — Best classic remake
System Shock (the 2023 Nightdive remake) rebuilt the 1994 original from the ground up. Citadel Station is still the genre’s most influential setting; SHODAN is still its best villain. The remake keeps the original’s bleak inventory grid and labyrinth maps while modernizing controls.
Where it falls short: Map design assumes you take notes; modern players used to waypoints will struggle. Combat is functional but rarely thrilling. Some puzzle solutions require the audio logs you’re tempted to skip.
Pricing:
- Free: no
- Paid: $39.99 base, often $20 on sale
- Platforms: Windows, macOS, Linux
Download: System Shock on Steam
Bottom line: Play this when you want to see the game that taught Dead Space and Prey what sci-fi horror was.
6. Signalis — Best retro survival horror
Signalis is rose-engine’s 2022 indie that fuses classic Resident Evil-style survival horror with Ghost in the Shell anime aesthetics. The six-hour campaign is tightly designed, the inventory limits feel like a fair puzzle, and the multiple endings reward note-taking and replays.
Where it falls short: Combat is intentionally clunky; tank-style controls split opinion. The story leans on the player to do interpretive work; some hate that. The ending tree requires guides to fully unpack.
Pricing:
- Free: no
- Paid: $19.99 base, $10 on sale
- Platforms: Windows, macOS, Linux
Download: Signalis on Steam
Bottom line: Best short sci-fi horror campaign on PC and one of the most distinctive indies in years.
7. Observation — Best calm narrative horror
Observation is No Code’s slow-burn space horror where you play the AI on a research station, watching the crew through cameras and granting access to compartments. There’s no combat, no enemies; the horror is structural — what happened to this station and what is the player actually doing here.
Where it falls short: Puzzles are simple by genre standards. Camera-switching navigation is awkward at first. Several jump scares feel out of place in an otherwise restrained game.
Pricing:
- Free: no
- Paid: $24.99 base, $6 on sale
- Platforms: Windows, macOS
Download: Observation on Steam
Bottom line: Best pick when you want sci-fi horror without combat and you can stomach a slow burn.
How to pick the right one
If you want one weekend pick, Dead Space (2023) is the cleanest entry: modern remake, tight pacing, and the genre’s foundational gameplay. If you want the most sustained scare per hour, Alien: Isolation, but block the time. If you want story over jump scares, SOMA is the strongest argument for sci-fi horror as a serious medium. If you want a sprawling immersive sim with horror tension layered in, Prey. If you want the genre’s grandparent in modern shape, System Shock. If you have one short evening, Signalis at six hours hits the hardest per minute. If you want calm horror without combat, Observation.
Skip the genre this round if you don’t have a good headset or speakers; every game on this list lives or dies on sound design, and even Dead Space loses half its impact through tinny laptop speakers.
FAQ
What is the scariest sci-fi horror game?
Alien: Isolation tops most lists for sustained dread because the Xenomorph genuinely cannot be predicted. SOMA scares people differently — less about jump scares, more about ideas — and tends to stick with players longer.
Is there a Dead Space 2 remake?
EA paused the Dead Space remake series after the 2023 release of the first game. There is no announced Dead Space 2 remake as of 2026. The 2011 original Dead Space 2 still works on modern PCs with community patches.
What’s the best sci-fi horror game on Steam Deck?
SOMA, Signalis, and Observation all run beautifully on Deck. Dead Space (2023) is Playable but pushes the hardware. Alien: Isolation runs well after a few setting tweaks for ultra-wide screens.
Is Star Trek: Shadow Frontier out?
Bloober Team announced Star Trek: Shadow Frontier at Summer Game Fest 2026 with a 2027 target window. It isn’t playable yet. The Star Trek games on Steam right now are older titles that don’t fit the horror genre.
What sci-fi horror games are coming in 2026?
The most-watched 2026 releases include Star Trek: Shadow Frontier (Bloober Team, sci-fi horror, 2027 target) and a few indie follow-ups to Signalis. Most of the year’s biggest horror releases have been folk-horror leaning rather than sci-fi.
