Subnautica 2 Best Base Locations

Field Notes

1. 

   Step 1Biome-onlyCommunity note

   Choose a base for loops, not screenshots

   Make the base reduce repeated travel.

   A strong early base sits near Titanium, Copper, Quartz and Silver loops while leaving a simple return line to the lifepod or known landmarks.

   A pretty base that sits far from your current material loop is a tax. Early bases should shorten Titanium, Copper, Quartz and Silver trips. If a location makes those runs clearer, it is probably better than a more dramatic spot that adds travel every time you craft.

   Before building, swim the loop once without placing anything. If the route is still confusing, the base will not fix it.

   Map hint

   Compare base-location markers with Silver and Quartz focused maps before committing.

   Do this

   • Nearby starter resources checked
   • Return route repeated once
   • Storage need confirmed

   Watch for

   • Choosing a scenic spot that makes every craft slower

   Next: Check depth bands before building deeper or farther out.

   Step 2Route noteCommunity note

   Use depth bands before building deep

   Avoid staging deeper than your oxygen or vehicle comfort supports.

   Deep and abyss-adjacent bases can look efficient, but they punish weak oxygen, weak vehicle prep and incomplete cave knowledge.

   A deeper base can be efficient later, but it punishes early saves. If reaching the build site already uses most of your oxygen or vehicle comfort, the base is too early. Depth bands give you a quick reality check before you invest materials.

   Use deep bases as staging points after the route is familiar, not as an attempt to make an unfamiliar route safe.

   Map hint

   Turn on Depth Bands and Caves before considering deep staging locations.

   Do this

   • Depth band checked
   • Vehicle or oxygen comfort confirmed
   • Cave exits understood

   Watch for

   • Building deep because it looks close to late objectives

   Next: Decide whether you need a starter base or a late staging base.

3. 

   Step 3Biome-onlyGuide note

   Separate starter base and late staging base

   Avoid asking one base to solve every route.

   Starter bases should support tools and oxygen. Late staging bases should support Power Plant, Observatory and ruin material routes.

   The first base should make tools, oxygen and starter materials easier. A late staging base should support Power Plant, Observatory, hot caves or ruin material routes. Those are different jobs, and one location rarely does both well.

   Keep the starter base simple. Add the late staging base only when you can name the route it supports.

   Map hint

   Use resource filters for starter bases and story/depth filters for late staging bases.

   Do this

   • Starter job defined
   • Late staging job defined separately
   • Materials not split too early

   Watch for

   • Moving the whole base every time a new signal appears

   Next: Use late route guides before choosing a staging base near story areas.

   Step 4ApproximateGuide note

   Treat abandoned base markers as landmarks

   Use existing base-style markers for orientation, not blind copying.

   Existing base-location markers are useful landmarks, not automatic recommendations. Check nearby resources and exits before copying a location.

   A base-location marker can tell you where players or guide notes pay attention. It does not automatically mean the location is right for your save. Check the resources, depth, cave exits and return route around it before copying the spot.

   If the marker is approximate or pending review, treat it as an area to inspect. Build only after the route proves itself in your current save.

   Map hint

   Open base-location markers, then overlay the resource or route filter that matters to your current stage.

   Do this

   • Marker used as landmark
   • Nearby resources checked
   • Current-save route tested

   Watch for

   • Copying a marker without checking the surrounding loop

   Next: Return to First Hours for starter planning or Power Plant and Observatory for late staging.
