As a writer who’s spent 15 years dissecting virtual worlds, I can say Subnautica is a masterpiece. Unknown Worlds’ 2018 gem strands you on an alien ocean planet, 4546B, where survival means scavenging, crafting, and facing leviathans that jolt your pulse.
Its blend of exploration, tension, and awe is tough to beat. If you’re hunting games like Subnautica to chase that high, I’ve got ten titles from the past decade that deliver—each tested thoroughly, from base-building marathons to panic-fueled escapes.
I’ve expanded the overviews to give you the full picture of their worlds, mechanics, and vibes, plus a comparison table, pro tips, and 2025 insights to make this the ultimate resource for games like Subnautica.
Why Subnautica Sets the Bar
Subnautica drops you into a vibrant abyss where every biome tells a story. You gather resources, manage oxygen, and build seabases while unraveling an alien mystery. The survival loop is tight—never a chore—and the deeper you dive, the weirder it gets.
My first run-in with a Reaper Leviathan was chaos: bubbles, roars, and a mad dash to safety. Games like Subnautica need to match that mix of dread, discovery, and freedom.
Let’s dive into ten that come close.

Use this to pick your next dive. Detailed breakdowns below.
1. Subnautica: Below Zero
Subnautica: Below Zero (2021), Unknown Worlds’ sequel, trades Subnautica’s tropical reefs for the icy waters of planet 4546B’s arctic sector. You play Robin Ayou, a xenobiologist investigating her sister’s death amid corporate secrets.
Gameplay mirrors the original’s survival-crafting core: gather resources like quartz and lithium, craft tools, and build bases to withstand subzero temps. The world blends underwater biomes—think glowing Twisty Bridges and treacherous Crystal Caves—with land-based tundras and ice caves.
New mechanics, like managing body heat and piloting a Seatruck (a modular submarine), add depth. The story’s more structured, delivered via voice-acted logs and alien artifacts, guiding you to encounters with horrors like the Shadow Leviathan. Progression feels tighter than Subnautica’s sprawl, with a 20-30 hour campaign that balances exploration and narrative.
The atmosphere? Equal parts serene and suffocating—I’d swim through shimmering kelp, then freeze as an Ice Worm erupted nearby.
Why It Feels Like Subnautica:-
It’s Subnautica with a parka. Base-building’s as addictive—I engineered a multi-room outpost with moonpools to rival 4546B’s best. The story leans harder into plot than the original, but the survival loop’s just as gripping. X fans in 2025 call it “cozier yet scarier” (Jan post).
Standout Moment:-
The Crystal Caves’ glow hypnotized me—until a leviathan’s roar snapped me back. It’s Subnautica’s beauty-and-beast dance, iced over.
2. No Man’s Sky
Hello Games’ No Man’s Sky (2016, overhauled through 2025) is a galaxy-sized sandbox where you’re a traveler hopping between procedurally generated planets.
You mine resources (copper, oxygen), trade with aliens, and upgrade ships to explore 18 quintillion worlds. Survival means managing hazard protection against storms or toxic air, while base-building lets you craft outposts from simple domes to sprawling colonies.
The game’s evolved with underwater biomes, exocraft vehicles, and VR support, making it a heavyweight in games like Subnautica. Story threads—like the Atlas Path—offer loose guidance, but the real draw is freedom: land on a desert moon, dive into an ocean trench, or dogfight pirates in orbit.
Planets vary wildly, from barren rocks to jungles teeming with six-legged fauna. My 100+ hours revealed a cycle of discovery and tinkering—every session felt like charting Subnautica’s reefs, just across stars. The 2025 “Worlds Part II” update added richer aquatic zones, per X buzz.
Why It Feels Like Subnautica:-
You’re a lone explorer in alien wilds, scanning lifeforms and building bases. It’s less tense but matches Subnautica’s sandbox joy. X posts praise its “Subnautica-like freedom, just infinite” (Feb 2025).
Standout Moment:-
My cliffside base on a crimson planet, watching floating islands, felt like Subnautica’s seabase dreams.
3. The Long Dark
Hinterland Studio’s The Long Dark (2017) strands you as Will Mackenzie, a pilot crashed in Canada’s wilderness after a geomagnetic storm kills tech. This first-person survival sim demands you scavenge food, fuel, and tools to survive blizzards, wolves, and starvation.
No sci-fi flair—just raw nature across regions like Mystery Lake’s forests or Coastal Highway’s icy shores. Gameplay hinges on managing warmth, hunger, thirst, and fatigue, with dynamic weather turning a sunny hike into a whiteout death trap. You’ll hunt rabbits, fish through ice, or risk frostbite for a rifle.
Unlike Subnautica’s bases, you fortify existing cabins, but crafting (e.g., bows, hides) feels just as vital. The episodic story mode weaves a quiet tragedy, while sandbox survival offers 100+ hours of solitude.
My runs were grueling—I’d limp to shelter, half-frozen, cursing a wolf’s howl. In 2025, X players still call it “punishingly real.”
Why It Feels Like Subnautica:-
Isolation’s king. Every resource run’s as tense as an oxygen dive. It’s No Man’s Sky’s grit without the stars, raw like Subnautica’s early game.
Standout Moment:-
Killing a deer at dawn, starving, rivaled Subnautica’s clutch harvests.
4. Astroneer
System Era Softworks’ Astroneer (2019) is a vibrant space adventure where you’re an astronaut colonizing seven distinct planets, from lush Sylva to arid Calidor.
You gather resources (resin, ammonium), craft vehicles, and terraform landscapes with a deformable terrain tool. Gameplay’s a crafting-exploration loop: mine quartz for power, build a rover, then link bases with printers and labs.
Oxygen tethers anchor you to bases, mimicking Subnautica’s dive limits, but the vibe’s playful—no leviathans, just cave hazards like gas pods. Progression unlocks tech (drills, rockets) over 30-50 hours, with endgame goals like core activation adding purpose.
Co-op shines, letting you share Subnautica-style builds with friends. I’d spend hours sculpting neon-lit bases, lost in the flow. X in 2025 loves its “zen Subnautica vibes” for chill explorers.
Why It Feels Like Subnautica:-
Base-building’s a joy, with modular setups rivaling Subnautica’s moonpools. It’s No Man’s Sky’s cousin, less vast but cozier.
Standout Moment:-
My rover fleet crossed a glowing canyon, pure Subnautica Seamoth energy.
5. Outer Wilds
Mobius Digital’s Outer Wilds (2019) is a time-looping mystery where you’re a Hearthian astronaut exploring a handcrafted solar system. Every 22 minutes, the sun goes supernova, resetting your progress—but knowledge carries over.
You jetpack across planets like brittle Timber Hearth, waterlogged Giant’s Deep, or crumbling Brittle Hollow, piecing together Nomai ruins to solve an ancient puzzle. No crafting or survival, just pure discovery: fly a scout probe, decode glyphs, or dodge anglerfish in foggy voids.
The world’s compact—five planets, a few moons—but dense with secrets, unfolding over 15-25 hours. Atmosphere’s a mix of cozy campfires and cosmic dread, with a banjo soundtrack that haunts.
My runs felt like Subnautica’s deep dives, chasing “what’s next?” X fans in 2025 still avoid spoilers, praising its “Subnautica-tier wonder.”
Why It Feels Like Subnautica:-
Planets are biomes, each a story like Subnautica’s reefs. It’s Astroneer’s heart with Subnautica’s brain.
Standout Moment:-
A black hole jump echoed Subnautica’s portal thrills—mind blown.
6. Raft
Redbeet Interactive’s Raft (2022) casts you as a survivor on a tiny raft in a flooded Earth, scavenging debris to survive. You hook floating barrels for wood and plastic, craft nets and purifiers, and dive into reefs for copper or clay.
The world’s a vast ocean dotted with islands—abandoned rigs, coral atolls, sunken domes—each hiding story fragments about a lost civilization. Sharks nibble your raft, forcing repairs, while crafting expands it into multi-story bases with farms and engines.
Progression spans 20-40 hours, from jury-rigged floats to high-tech yachts, with bosses like rhinos adding spikes of danger. Co-op’s a blast, turning dives into team ops.
My sessions were Subnautica déjà vu—every coral dive or island raid felt like 4546B’s shallows. X in 2025 calls it “Subnautica’s multiplayer twin.”
Why It Feels Like Subnautica:-
Ocean survival’s the core. Building a raft empire mirrors Subnautica’s seabases—pure DIY joy.
Standout Moment:-
My raft grew into a fortress, rivaling Subnautica’s grandest hubs.
7. Abzu
Giant Squid’s Abzu (2016) is an underwater poem where you’re a nameless diver gliding through oceans, from sunlit reefs to abyssal ruins. There’s no survival—just exploration across linear chapters, each a dazzling biome of fish schools, kelp towers, and ancient tech.
You interact with sea life (ride a manta, wake a whale) and solve light puzzles to restore ecosystems, unfolding a wordless tale over 3-5 hours. Controls are fluid—think Subnautica’s swimming, but weightless—paired with a soaring Austin Wintory score.
It’s meditative, not tense; no oxygen bars or predators, just wonder. I’d linger in currents, awed by visuals that rival Subnautica’s best. X artists in 2025 share Abzu shots, calling it “Subnautica’s chill pill.”
Why It Feels Like Subnautica:-
It’s Subnautica’s beauty without stakes. Reefs feel like 4546B’s safe zones, pure eye candy.
Standout Moment:-
Riding a whale through a glowing trench was Subnautica’s peace distilled.
8. Firewatch
Campo Santo’s Firewatch (2016) is a first-person narrative where you’re Henry, a 1980s fire lookout in Wyoming’s Shoshone Forest. You explore trails, climb cliffs, and talk via radio with your supervisor, Delilah, unraveling a mystery about missing hikers.
There’s no crafting—just a map, compass, and your wits—across a 4-6 hour story. The world’s a vivid painting: golden meadows, windy canyons, and eerie caves that feel alive.
Gameplay’s light (find items, report clues), but the dialogue and atmosphere carry it—every rustle or shadow spikes your pulse. It’s grounded, not alien, yet its isolation mirrors Subnautica’s lone dives.
I’d trek at dusk, half-expecting a leviathan in the pines. X in 2025 lauds its “Subnautica-like loneliness, earthbound.”
Why It Feels Like Subnautica:-
Solitude’s the star. Forests are as immersive as reefs, with stories in every nook.
Standout Moment:-
A shadowy figure at dusk echoed Subnautica’s deep-sea chills.
9. The Forest
Endnight Games’ The Forest (2018) crashes you on a lush island after a plane wreck, tasked with rescuing your son from cannibals. This survival-horror blends crafting, building, and exploration: chop trees for forts, hunt deer for food, and raid caves for gear like flares or a katana.
The world’s dense—rainforests, lakes, snowy peaks—crawling with mutants who stalk you at night. Base-building’s robust, from treehouses to spiked walls, rivaling Subnautica’s outposts. Survival means managing hunger, cold, and sanity, with a 15-30 hour story plus endless sandbox mode.
Caves are the kicker—claustrophobic, creepy, and packed with lore. My nights were tense, axe ready, like Subnautica’s leviathan hunts. X in 2025 shares epic Forest builds, some Subnautica-worthy.
Why It Feels Like Subnautica:-
DIY forts and constant threats echo Subnautica’s survival. It’s Raft’s grit, darker.
Standout Moment:-
My fortress repelled a mutant swarm, tense as Subnautica’s alarms.
10. Returnal
Housemarque’s Returnal (2021) is a third-person roguelike where you’re Selene, a pilot looping on Atropos, an alien planet. Each death resets you, but upgrades (like faster dashes) persist.
You shoot through biomes—ruined citadels, crimson swamps, snowy wastes—packed with hostile fauna and bullet-hell chaos. Exploration’s key: find logs, glyphs, or xeno-tech to unravel Selene’s past and Atropos’ secrets, over 20-40 hours. Weapons evolve (shotguns, acid launchers), and haptics make every hit visceral.
It’s less crafting than Subnautica, more action, but the alien vibe and lore scans hit home. I’d sprint through fog, heart racing like a Subnautica dive. X in 2025 calls its PS5 version “Subnautica’s intensity, amped.”
Why It Feels Like Subnautica:-
Biomes shift like 4546B’s depths, with PDAs as audio logs. It’s The Forest’s edge in space.
Standout Moment:-
A swamp run with glowing parasites screamed Subnautica’s Blood Kelp.
How These Games Connect in 2025
These ten weave Subnautica’s DNA: Below Zero and Raft own aquatic survival, No Man’s Sky and Astroneer scale exploration to stars. The Long Dark and The Forest match stakes, Outer Wilds and Firewatch stories. Abzu borrows art, Returnal alien weirdness.
In 2025, VR and co-op surge—No Man’s Sky’s oceans and Raft’s multiplayer shine—but Subnautica’s solo awe reigns. I’d bounce between them, each feeding my 4546B fix.
