Best Base Locations in Subnautica 2

Building a base in Subnautica 2 is a much more important thing than it was in its prequel, as it’s a core survival system not just for you but also for your teammates. Especially with underwater threats becoming far more aggressive, choosing the right location can make or break your entire run.

A poorly placed base can slow progression, waste resources, and leave you exposed during dangerous encounters. That’s why knowing the perfect base location for each stage of the game matters more than ever, and why this guide breaks down exactly where you should be building as you progress.

Subnautica 2 Base Locations Guide (Early to Late Game)

Base building in Subnautica 2 works best when you treat it as a moving system rather than a single permanent home. As you progress, your needs shift dramatically, and your base should evolve with you instead of holding you back.

One important thing to remember, the game is currently in early access, meaning the map is still limited. Because of this, base recommendations mainly focus on early to mid-game progression, and they shouldn’t be a massive “forever” base. That’s why, for now, it needs to be a “moving system.”

Early stage:

In the early game, you want a base placed in areas where basic materials are everywhere and easy to collect. Why? Because this is the stage where you’re constantly crafting essentials like oxygen upgrades, scanners, and movement tools, so every second spent traveling is a delay. A good early base reduces that downtime by keeping common resources within a short swim in multiple directions. It should feel like a quick resupply station, not a permanent home.

Recommended Location: Near the Lifepod

Mid stage:

By the mid-game, you already have the basics down, but now progression depends on more advanced tools and deeper exploration. This means you’ll be diving further into the ocean, visiting wrecks, and collecting rarer materials like silver, lead, and advanced upgrade components.

Your base now needs to support longer/harsher expeditions and faster turnaround between dives, acting as a central hub for scanning, crafting, and storage.

Recommended Location: Near the Heat Caves

Late Stage

In the late game, survival will most likely shift into deep-ocean exploration, where returning to the surface is no longer a ‘practical’ option. At this point, your base becomes a forward operating station built deep within hostile environments. It’s less about convenience and more about endurance: supporting long dives, high-risk encounters, and continuous progression into unknown territory.

NOTE: The developers have already shared a roadmap indicating upcoming updates, including new biomes, improved co-op systems, and expanded gameplay features.

Key Base Building Tips in Subnautica 2

Before diving into Subnautica 2, it’s important to understand the core principles that make a base truly effective. These tips apply across all stages of the game and will help you avoid common mistakes while improving your overall progression.

1. Prioritize resource access over aesthetics
2. Build centrally between biomes to reduce travel time early on
3. Always ensure safe escape routes in case of predator encounters
4. Expand your base gradually instead of building large structures too early
5. In co-op, design for multiple players to craft and store items simultaneously
6. Prepare for deeper progression zones by planning expansion space early

Following these fundamentals will make your base far more efficient and adaptable as you progress through the game. A strong setup early on can save you hours of backtracking and resource grinding later.
