Subnautica is one of the best survival games ever made, and it still has no Android port. The co-op mode announced for Subnautica 2 has renewed interest in underwater exploration games, but that sequel is also PC and console only. If you own an Android phone and want the same loop of diving, resource gathering, building, and avoiding things that want to eat you, you need to look elsewhere.
This article covers seven Subnautica alternatives that actually run on Android. Some match the oceanic atmosphere closely; others swap the ocean for open wilderness or a voxel world but keep the same core mechanics. All seven are available on Google Play as of May 2026.

Why Subnautica fans go looking for alternatives
Subnautica is the type of game Android players can only experience through video or cloud gaming. Three specific gaps drive the search:
No mobile port exists. Unknown Worlds has never shipped a mobile version. The game’s rendering requirements and control scheme do not translate easily to touch, so this gap is unlikely to close soon.
Subnautica 2 is co-op, but still PC-only. The Eurogamer coverage of Subnautica 2’s multiplayer mode in 2025 generated interest, but the game targets PC first. Android players hoping the co-op hype would bring a mobile version are still waiting.
Cloud gaming works, but not offline. Xbox Game Pass Ultimate lets you stream Subnautica through the cloud on Android, but that requires a solid internet connection and a monthly subscription. Players who want something they can actually install and play offline are out of luck with the original game.
The alternatives below fill these three gaps differently. Some are free, some are paid. Some work offline. One has genuine co-op. The right pick depends on what drew you to Subnautica in the first place.
The 7 best Subnautica alternatives for Android
Ocean Survival -- Best for the closest Android approximation of Subnautica
Ocean Survival drops you into an ocean with nothing. You gather wood and debris floating on the surface, build a raft, dive below to collect sand and stone, and eventually construct an underwater shelter with working lights, furniture, and storage. The crafting tree is deep enough that most players spend their first few sessions just figuring out the tech progression. Compared to Subnautica vs Ocean Survival, the mobile game lacks the story depth and alien biome variety, but the core loop of resource gathering, building, and managing oxygen underwater translates surprisingly well to touch controls.
Where it falls short: the free version runs frequent interstitial ads after deaths and loading screens. The ocean world is smaller than Subnautica’s alien planet, and there is no equivalent to Subnautica’s narrative drive.
Pricing:
- Free with ads
- No paid tier to remove ads permanently via in-app purchase at last check (only single-purchase item options)
- vs Subnautica: Free entry, but ad-supported
Bottom line: The best starting point if you want to feel what Subnautica is like on Android without spending anything.
Raft Survival: Ocean Nomad -- Best for co-op survival on the water
Raft Survival: Ocean Nomad puts you on a small floating platform in the middle of an endless ocean. You hook debris drifting past, expand your raft, build a water purifier, crop garden, and cooking station, then use a sail to navigate to islands and underwater wreck sites. The co-op mode supports up to four players on the same raft, which is as close to Subnautica 2’s co-op premise as anything available on Android right now. The shark that periodically attacks your raft planks provides the same low-level threat that Subnautica’s leviathans do.
Where it falls short: the free version is aggressive with banner ads and IAP prompts for resource packs. Underwater content is limited compared to Subnautica; most gameplay happens above the surface.
Pricing:
- Free with ads and in-app purchases
- Premium resource packs from $1.99
- vs Subnautica: Free but monetized; Subnautica is a one-time purchase
Bottom line: The best pick if you want Subnautica-style co-op survival and do not mind a free-to-play monetization model.
ARK: Survival Evolved -- Best for players who want the deepest survival experience
ARK: Survival Evolved is the closest thing on Android to a full survival sandbox with the scope of a PC game. You wake on an island with nothing, punch trees, build a shelter, and eventually tame over 100 creatures including dinosaurs. The mobile version carries most of the content from the PC release: tribe mechanics, boss fights, breeding, and a map large enough to take weeks to fully explore. ARK vs Subnautica is a different atmosphere (jungle, ice, desert biomes versus ocean), but the player-driven discovery and escalating tech progression feel similar.
Where it falls short: ARK demands significant storage (over 2GB) and a mid-range or better device to run smoothly. The original PC version’s performance problems carry over to mobile, and the paid “Primal Pass” subscription unlocks premium servers.
Pricing:
- Base game: free to download
- Primal Pass subscription: $4.99/month for premium servers and cosmetics
- vs Subnautica: Comparable investment if you subscribe; free to try without the pass
Bottom line: The best choice if you want a full-scale survival game with long-term progression and do not mind paying for a subscription to access the best servers.
Ocean Survival 3D -- Best for low-end devices
Ocean Survival 3D covers the same ocean survival basics as its larger cousins: gather driftwood, build a raft, hunt fish, manage hunger and thirst, and explore islands. The graphics are simpler than Ocean Survival or ARK, which is a feature on older Android hardware. Ocean Survival 3D vs the original Ocean Survival is a question of performance priority; the 3D variant runs on devices with 2GB RAM where the first game starts to struggle.
Where it falls short: the crafting tree is shallower than competing titles, and underwater content amounts to brief diving sessions rather than a full exploration system.
Pricing:
- Free with ads
- vs Subnautica: No cost, no depth comparable to the PC game
Bottom line: A sensible pick for players with older phones who want ocean survival without spending money or straining their hardware.
Raft Survival Ark Simulator -- Best for the combined raft and island loop
Raft Survival Ark Simulator blends two mechanics: you start on a raft, sail to islands, explore them on foot, and bring resources back to expand your floating base. The island exploration sections involve simple dungeons and wildlife encounters that break up the repetitive resource-hooking that can wear thin in pure raft games. The raft-building system allows for multi-story platforms with enclosed rooms, which gives a sense of base progression similar to Subnautica’s base-building.
Where it falls short: graphics are noticeably below ARK and even Ocean Survival. Threat systems are simple, and the game leans toward casual play rather than the tense resource management that defines Subnautica.
Pricing:
- Free with ads and IAP
- vs Subnautica: Free with a lighter experience
Bottom line: Good for players who want variety in their survival loop without committing to a heavier game like ARK.
Survivalcraft 2 -- Best offline survival sandbox
Survivalcraft 2 is a paid, no-ads survival sandbox that runs completely offline. You spawn on a procedurally generated island, chop down trees, mine stone, build shelters, and face a day/night cycle that brings wolves and other animals out after dark. The game’s physics engine is one of the most capable on Android, supporting complex electrical wiring, movable parts, and furniture placement that Subnautica’s base-building fans will appreciate. Survivalcraft 2 vs Subnautica is a land-versus-sea swap, but both reward players who take their time exploring every corner of the world.
Where it falls short: it costs money upfront and the community is smaller than Minecraft’s, so there is less community content to extend the game. The underwater areas, while present, are not the focus.
Pricing:
- Paid: approximately $3.99 (one-time)
- No in-app purchases, no ads
- vs Subnautica: Cheaper one-time purchase with no ongoing costs
Bottom line: The best pick for players who want a proper offline sandbox with no monetization strings attached, and do not mind swapping ocean for wilderness.
Last Day on Earth: Survival -- Best for players who want base raiding and PvE
Last Day on Earth: Survival sets you in a post-apocalyptic world overrun by zombies. You gather materials, build and reinforce a base, craft weapons, and push out to clear enemy locations and bunkers. The base-building loop shares DNA with Subnautica: you keep upgrading your home structure, unlock deeper crafting tiers, and face increasingly difficult enemies when you venture out. Multiplayer raids and clan systems add a social layer that single-player survival games lack. Last Day on Earth vs Subnautica is a thematic opposite, but the escalating progression and constant resource pressure feel familiar.
Where it falls short: the free-to-play model is aggressive. Energy systems limit how long you can play in a session without waiting or spending. The atmosphere skews toward grim post-apocalypse rather than Subnautica’s awe-driven alien exploration.
Pricing:
- Free with energy timers and in-app purchases
- Premium cosmetics and resource packs from $1.99
- vs Subnautica: Free to start; costs accumulate if you engage with IAP
Bottom line: Good for players who want survival with a combat-heavy, base-defense focus and enjoy multiplayer elements.
Minecraft -- Best for players who want unlimited world depth
Minecraft needs little introduction, but it earns its place on this list because its survival mode delivers the same “figure it out yourself” discovery loop that defines Subnautica. The ocean biomes in Minecraft are substantial: shipwrecks, ocean monuments with Elder Guardians, coral reefs, and underwater ruins give dedicated explorers weeks of content. Community-made ocean survival maps and datapacks take it further. Minecraft vs Subnautica is a fair comparison for players who loved the freedom of exploration and base-building more than the alien storyline.
Where it falls short: the base game costs money, and the touch controls take adjustment. The survival threat level is lower than Subnautica’s by default unless you increase difficulty or use specific maps.
Pricing:
- Paid: approximately $6.99 (one-time on Google Play)
- Marketplace content available as additional purchases
- vs Subnautica: Similar price point, dramatically wider content library
Bottom line: The right pick if you want a survival sandbox you will never fully exhaust, with a community large enough that someone has already built the oceanic experience you want.
How to choose the right Subnautica alternative
Pick Ocean Survival if what you want is an underwater base-building loop on Android right now. It is free, it runs on most phones, and the core mechanics are closer to Subnautica than anything else on this list.
Pick Raft Survival: Ocean Nomad if the co-op angle is your priority. It is the only game here with genuine multiplayer survival on water, and the Subnautica 2 co-op coverage makes this the most timely choice.
Pick ARK: Survival Evolved if you want a survival game you will still be playing six months from now. The content library is vast, the taming mechanics are unique, and the game has been updated for years. Budget for the Primal Pass if you want to play on populated servers.
Pick Survivalcraft 2 if you need offline-only play without any monetization. It is the cleanest premium option on this list.
Pick Minecraft if you want the survival sandbox with the deepest community. The ocean biomes give you a Subnautica-adjacent experience, and the wider world keeps the game interesting far longer than any niche ocean survival app.
Stay on cloud gaming with Xbox Game Pass if you specifically want Subnautica’s alien atmosphere and narrative. The mobile alternatives deliver survival mechanics but none of them replicate the Planet 4546B world. Streaming the actual game through Game Pass on Android is still an option if connectivity is not a constraint.
