Ambrosia Sky landed on Steam this month with a pitch nobody expected: PowerWash Simulator, but on an asteroid colony overrun by luminous alien fungus. Soft Rains built a slower kind of sci-fi immersive sim, one where the ambient dread of a dead colony sits next to the small joys of clearing a contaminated corridor. Reviews call it Metroid Prime crossed with a cleaning game, and the mix works because the fiction gives every scrub a reason. If Ambrosia Sky pulled you in but you’re already through Act Two, here are seven Ambrosia Sky alternatives that keep the same atmospheric, ship-hallway pacing on desktop.

Why Ambrosia Sky sticks
The fiction earns the cleaning. Ambrosia Sky asks you to harvest fungal strains rather than scrub grime, so every completed sample tells you something new about what killed the colony. Environmental storytelling carries most of the plot, and the pace stays measured because the game trusts the reader to notice a scorched wall or an open airlock. Even players who bounced off the immersive-sim label agreed the moment-to-moment traversal has a quiet gravity most modern shooters miss.
Systems reward exploration, not combat. Fire, electricity, and chemistry all interact with the fungus, and finding a shortcut through a locked bay usually means noticing a leaked canister you can ignite. Combat exists but feels intentional, closer to a defensive tool than a power fantasy. That is unusual in a genre that keeps drifting toward action, and it is why players who loved Prey found something familiar here.
The soundscape sells the isolation. Cracked ventilation, distant hum, the click of your reclaimer, and long silences between them. Ambrosia Sky trusts silence in a way that makes the alien noises land harder when they arrive. If you want a game that respects headphones and slow evenings, this is the one.
The alternatives
Prey (2017)
Prey is the closest structural match to Ambrosia Sky on desktop. Talos I is an orbital station overrun by shape-shifting Typhon, and Arkane’s design gives you a dozen answers to every locked room. GLOO cannon, mimic vision, hacking, or the recycler charge, none of them wrong. If the fungus in Ambrosia Sky felt like a system to study rather than a boss to shoot, Prey extends that idea across a full station.
Where it falls short: Combat is stiffer than the exploration deserves, and late-game encounter pacing dips. Skip the Mooncrash DLC if you dislike roguelike runs.
Pricing: Paid ($30, often deeply discounted).
Platforms: Windows.
Download: Steam
Bottom line: Pick this if you loved poking Ambrosia Sky’s systems and want a bigger station to unravel.
Signalis
Signalis trades polygons for a lo-fi PS1 aesthetic and a tighter grip on horror. You wake on a frozen mining colony as a Replika android searching for someone lost decades ago. Puzzle-heavy exploration, limited inventory, tape-based save rooms, everything a survival-horror fan expects, wrapped in one of the most striking art directions in the genre.
Where it falls short: Combat is deliberately clunky, meant to make you avoid fights. Puzzles occasionally require rereading a note two rooms back.
Pricing: Paid ($20).
Platforms: Windows, macOS.
Download: Steam
Bottom line: For the players who wanted more dread and less cleaning; the sci-fi loneliness lands the same way.
Alien: Isolation
Alien: Isolation is still the benchmark for stalker-AI horror ten years on. Sevastopol station has one enemy that matters, and it learns your patterns. If Ambrosia Sky’s quiet corridors made you nervous, Isolation will teach you what real corridor tension feels like.
Where it falls short: The run time is long for a horror game; some players tap out around hour twelve. Save points are punishingly spaced.
Pricing: Paid ($40, discounted often).
Platforms: Windows, macOS, Linux.
Download: Steam
Bottom line: The one to pick if you want the atmosphere dialled to eleven and the cleaning gameplay traded for pure survival.
SOMA
SOMA is Frictional Games’ underwater sci-fi story about identity and machines. Combat barely exists; you avoid, hide, and read. The ambient sadness reviewers keep attaching to Ambrosia Sky was arguably invented in SOMA, and it still hits harder than most modern narrative games.
Where it falls short: Stealth is basic, and the monster encounters are more frustrating than scary if you get spotted. Safe Mode disables enemy damage if you want the story unimpeded.
Pricing: Paid ($30).
Platforms: Windows, macOS, Linux.
Download: Steam
Bottom line: Best if you cared more about the melancholy of a dead colony than the systems clearing it.
PowerWash Simulator
PowerWash Simulator is the other half of Ambrosia Sky’s DNA, distilled. No enemies, no story stakes, just the meditative loop of watching a surface go from filthy to spotless. Local co-op and drop-in multiplayer make it easy to loop friends into a nightly cleaning ritual.
Where it falls short: No plot, no combat, no exploration. If Ambrosia Sky’s fiction was what pulled you in, this one will feel like the tool without the workshop.
Pricing: Paid ($25).
Platforms: Windows, macOS.
Download: Steam
Bottom line: For nights when you want the cleaning without the horror, this is the direct swap.
Void Bastards
Void Bastards turns Ambrosia Sky’s station raids into a comic-book roguelike. Every ship layout is procedural, every survivor you play is a disposable prisoner, and the loop is loot, escape, upgrade, repeat. The art style is a British 2000AD tribute, sharp and readable even when the screen fills with enemies.
Where it falls short: The roguelike loop can grind if you dislike restarting from base each mission. Combat is fine, never great.
Pricing: Paid ($30).
Platforms: Windows, macOS, Linux.
Download: Steam
Bottom line: Pick this for the tightest raid-and-return loop, wrapped in a distinctive comic-book presentation.
Dead Space (2023)
Dead Space was rebuilt from the ground up by Motive, and it is the most conventional pick here. Corridor sci-fi horror, dismemberment as a combat mechanic, and a dread-soaked Ishimura that owes an ancestor to every dead colony in the genre. If Ambrosia Sky felt too slow at points, Dead Space is a sharper, louder answer.
Where it falls short: Very jump-scare heavy compared to Ambrosia Sky’s slower dread. Requires beefier hardware than most on this list.
Pricing: Paid ($70).
Platforms: Windows.
Download: Steam
Bottom line: For the nights you want the sci-fi setting turned into a proper action-horror ride.
How to choose
Pick Prey if you loved the system-poking and want another station to unravel. Pick Signalis or SOMA if you cared more about the story and the ambient loneliness than the cleaning loop. Pick Alien: Isolation if the corridors made you nervous and you want that dialled up. Pick PowerWash Simulator if you want the meditative cleaning without the fiction. Pick Void Bastards if you want the raid-and-return loop turned into a proper roguelike. Pick Dead Space if you want the sci-fi horror turned into an action set-piece machine. Stay on Ambrosia Sky if what you loved is the exact mix of fungal harvesting and quiet exploration, because none of these do that specific blend.
FAQ
Is Ambrosia Sky finished with Act Two?
Yes. Ambrosia Sky launched as Act One in November 2025, and Act Two arrived as a free expansion in August 2026. Reviewers describe Act Two as the ending the story needed, and the base game now covers the full arc without a further paid DLC on the roadmap.
Is Ambrosia Sky a real immersive sim?
Sort of. Systems exist for fire, electricity, and chemistry, and they interact in interesting ways, but many players feel it sits closer to a linear adventure with immersive-sim flavour than a true Prey-style sandbox. If you want the deep systems, Prey is the honest recommendation.
Which of these runs on macOS?
Signalis, SOMA, PowerWash Simulator, Void Bastards, and Alien: Isolation all have native macOS builds on Steam. Prey and Dead Space are Windows-only.
Is there anything similar coming in 2026?
Cronos: The New Dawn from Bloober Team has a similar Eastern-European sci-fi horror pitch and lands later this year. Keep an eye on Scorn’s follow-up work if the biomechanical body-horror in Ambrosia Sky’s fungus resonated.
What’s the cheapest way to try the genre?
Void Bastards and Signalis both go on sale under $10 several times a year. Both give you a strong feel for the slower, exploration-first sci-fi vibe without a full-price commitment.
