Subnautica earns its devoted fanbase through a rare combination: a vast, hand-crafted alien ocean that rewards curiosity with genuine wonder and genuine dread in equal measure. Its genius is the layered depth gating — every new vehicle or oxygen upgrade opens a darker, stranger biome, making progression feel like peeling back the unknown rather than grinding numbers. The isolation, the bioluminescent beauty, and the careful environmental storytelling through PDA logs give it an atmosphere few games have matched.
When players ask for "games like Subnautica," they're really after one or more of three feelings: the survival-crafting loop in a hostile alien environment, the awe of exploring a strange, living ecosystem that clearly doesn't care whether you survive, or the slow-burn sci-fi mystery delivered through exploration rather than cutscenes. The best recommendations target whichever of those three hooks grabbed you hardest.

97%Below Zero is a standalone companion game set on the same alien ocean planet, adding a colder arctic biome, new creatures, deeper story, and new crafting trees while keeping the exact same survival-exploration DNA.
90%No Man's Sky is the closest large-budget match: first-person sci-fi survival crafting across procedurally generated alien worlds, with underwater biomes, base-building, and a story that unfolds through environmental exploration. The scale and freedom mirror Subnautica closely.
88%Outer Wilds puts you in a hand-crafted alien solar system that rewards pure curiosity and environmental storytelling, with no combat and a strong emphasis on awe and dread. Like Subnautica, progress is gated entirely by knowledge discovered through exploration rather than levelled stats.
82%Stranded Deep strands you on a Pacific island with only ocean between you and survival — you craft rafts, dive coral reefs for resources, hunt sharks, and build shelters. The first-person ocean survival loop is the closest single-player match to Subnautica on land.
80%Minecraft shares Subnautica's core survival-crafting loop: gather resources, craft tools, build bases, and push into increasingly dangerous biomes. The ocean update even adds underwater temples, deep trenches, and bioluminescent squid.
80%Astroneer replaces the alien ocean with alien planets but keeps the first-person exploration, resource extraction, base-building, and escalating equipment progression in a visually striking sci-fi setting. The sense of wonder at discovering new terrain is near-identical.
78%SOMA is set almost entirely in an underwater sci-fi research facility, sharing Subnautica's themes of isolation, alien biology, and existential dread. It trades crafting for a story-driven horror-puzzle experience with genuinely unsettling atmosphere.
75%Raft puts you on a small floating platform surrounded by endless ocean, gathering debris to expand your raft, crafting survival tools, and diving to ocean floors where sharks circle. The oceanic survival loop with incremental crafting progression closely echoes Subnautica.
72%Abzu is a wordless underwater exploration game with the same sense of alien ocean wonder, vivid bioluminescent coral reefs, and awe-inspiring megafauna encounters. The pace is gentle and meditative rather than tense.
65%💎 GemDave the Diver alternates between daytime free-diving sessions to hunt and discover sea creatures and nighttime sushi-restaurant management. The underwater world grows stranger and more exotic as you descend, echoing Subnautica's sense of layered ocean mystery.
62%Don't Starve drops you in a hostile alien-feeling wilderness and demands you craft, forage, and build shelter to survive ever-escalating threats — the same core anxiety loop as Subnautica on land. Its stark art style and unforgiving ecology create a similar sense of a world indifferent to your survival.
62%Green Hell is a hyper-realistic first-person jungle survival game with deep crafting, base-building, and an environmental story told through audio logs — structurally similar to Subnautica but far more punishing and land-locked.
58%BioShock shares the underwater sci-fi setting — Rapture is a crumbling art-deco city on the ocean floor — and the same sense of eerie beauty hiding mortal danger. The atmospheric environmental storytelling and isolation echo Subnautica's mood.
50%💎 GemManeater is an underwater open-world RPG where you navigate an ocean ecosystem, avoid apex predators, and unlock new zones by growing stronger — structurally mirroring Subnautica's layered depth gating. The oceanic environments range from sunlit shallows to crushing dark trenches.
45%💎 GemThe Swapper takes place on an abandoned space-station with a strong atmosphere of eerie isolation and a slow-burn sci-fi mystery delivered through environmental logs — tonal cousins to Subnautica's PDA entries. Its puzzle-exploration loop rewards patience and curiosity.

The key ingredients are exploration as the primary loop, a world that withholds its secrets behind physical or mechanical depth, and an atmosphere that makes you feel small and alone in something vast and alive. Most open-world survival games check the survival and crafting boxes but lose the wonder — which is why Outer Wilds and SOMA land so high despite having no crafting at all. They nail the feeling of being an undersized creature in an uncaring alien ecosystem, communicating story purely through the environment.
On the crafting-survival side, Minecraft and the off-list No Man's Sky are the closest mechanical fits — both share the resource-gather → tool-craft → new area unlocked loop. But Subnautica's narrow first-person focus on a single, hand-built world gives it a coherence and tension that procedural generation rarely replicates. If that crafted quality matters most to you, Stranded Deep or Subnautica: Below Zero are the honest next steps.
SOMA is the strongest pick for players who need deep ocean specifically — its Pathos-II facility sits on a real ocean floor, flooded corridors and all, and the monster-avoidance gameplay translates Subnautica's fear of large creatures into something genuinely terrifying. Abzu goes the opposite direction, offering a wordless, peaceful celebration of the same bioluminescent ocean majesty without a single survival threat — ideal after a stressful playthrough of the Crater. Dave the Diver is a left-field gem that captures the pleasure of descending into stranger, deeper water each day while wrapping it in a charming restaurant-management loop.
For players who want the ocean as a sandbox to inhabit rather than just visit, Maneater flips the predator dynamic (you are the apex creature this time) and structures its open underwater world in zone-gated tiers that feel recognizably Subnautica-adjacent, even if the tone is far more action-oriented.
Outer Wilds is the unanimous recommendation here — its mystery unfolds entirely through player-driven exploration, rewards patience and note-taking in exactly the way Subnautica's PDA does, and produces the same sense of standing on the edge of something ancient and indifferent. The absence of crafting or inventory management means nothing is between you and pure discovery. Off-list, Astroneer offers the closest equivalent with crafting restored: a first-person sci-fi exploration game on alien worlds that shares Subnautica's visual wonder and base-building loop, just without the water.
