Understanding Scanner And Blueprint Completion
Unlock essential equipment by systematically scanning fragments
This is an original reference for the first Subnautica. Your current depth rating, oxygen, available tools and navigation route determine when an objective is practical. Follow actual in-game PDA and Fabricator information for any values that vary by version.
How to use this information
Understand that technology must be unlocked by scanning the right objects, not just picking up salvage.
What to avoid
Do not repeat aimless visits to the same wreck without tracking what you have already scanned.
Step-by-step guide
Craft a Scanner as an early priority
Craft a Scanner as an early priority is a concrete milestone in this survival route, not a command to rush to the next depth. Start with Scanner. A handheld tool used to catalog organisms and collect blueprint data from fragments. Make this early; scan fragments systematically instead of hoarding random technology parts. The most common failure here is specific: Many blueprints require multiple fragments and cannot be unlocked by a single glance. Before leaving your staging point, review the equipment in your PDA, verify the depth of the objective and note which corridor you will take back. If you have not unlocked the required technology, scan fragments in known terrain and do a separate supply trip rather than risking all resources at once. The next connection is Wreck Exploration: Scattered Aurora wreck segments that contain fragments, PDA entries and supplies. Scan externally first, then enter with illumination, cutting tools and a planned exit. Those two topics form a useful checkpoint: finish the present task, repair any worn equipment, refill oxygen or cells, and update Beacons before you continue. Remember the related limitation: Squeezing through several sealed rooms without path markers risks getting lost. On this original-Subnautica route, a sensible plan is more valuable than a fixed set of unverified coordinates. Use this chapter as a decision path for your own save rather than assuming all fragments and resources have been found already.
Learn fragment and databank behavior
Learn fragment and databank behavior is a concrete milestone in this survival route, not a command to rush to the next depth. Start with Wreck Exploration. Scattered Aurora wreck segments that contain fragments, PDA entries and supplies. Scan externally first, then enter with illumination, cutting tools and a planned exit. The most common failure here is specific: Squeezing through several sealed rooms without path markers risks getting lost. Before leaving your staging point, review the equipment in your PDA, verify the depth of the objective and note which corridor you will take back. If you have not unlocked the required technology, scan fragments in known terrain and do a separate supply trip rather than risking all resources at once. The next connection is Grassy Plateaus: Broad red-grass areas with scattered wreckage and fragments for early equipment. Explore wreck outskirts with the Scanner and mark useful entrances with a Beacon. Those two topics form a useful checkpoint: finish the present task, repair any worn equipment, refill oxygen or cells, and update Beacons before you continue. Remember the related limitation: Sand Sharks and deeper trenches make blind descents risky. On this original-Subnautica route, a sensible plan is more valuable than a fixed set of unverified coordinates. Use this chapter as a decision path for your own save rather than assuming all fragments and resources have been found already.
Search accessible wreck outskirts
Search accessible wreck outskirts is a concrete milestone in this survival route, not a command to rush to the next depth. Start with Grassy Plateaus. Broad red-grass areas with scattered wreckage and fragments for early equipment. Explore wreck outskirts with the Scanner and mark useful entrances with a Beacon. The most common failure here is specific: Sand Sharks and deeper trenches make blind descents risky. Before leaving your staging point, review the equipment in your PDA, verify the depth of the objective and note which corridor you will take back. If you have not unlocked the required technology, scan fragments in known terrain and do a separate supply trip rather than risking all resources at once. The next connection is Mobile Vehicle Bay: A floating construction platform required to fabricate major vehicles. Deploy it in suitable open water near your staging base after scanning its fragments. Those two topics form a useful checkpoint: finish the present task, repair any worn equipment, refill oxygen or cells, and update Beacons before you continue. Remember the related limitation: It is not a vehicle you can drive or a permanent storage station. On this original-Subnautica route, a sensible plan is more valuable than a fixed set of unverified coordinates. Use this chapter as a decision path for your own save rather than assuming all fragments and resources have been found already.
Unlock vehicles and upgrade stations
Unlock vehicles and upgrade stations is a concrete milestone in this survival route, not a command to rush to the next depth. Start with Mobile Vehicle Bay. A floating construction platform required to fabricate major vehicles. Deploy it in suitable open water near your staging base after scanning its fragments. The most common failure here is specific: It is not a vehicle you can drive or a permanent storage station. Before leaving your staging point, review the equipment in your PDA, verify the depth of the objective and note which corridor you will take back. If you have not unlocked the required technology, scan fragments in known terrain and do a separate supply trip rather than risking all resources at once. The next connection is Early Blueprint Route: Use the Scanner on fragments to unlock necessary vehicle, tool and base technology. Explore Kelp Forest and Grassy Plateaus outskirts before pushing into deep zones. Those two topics form a useful checkpoint: finish the present task, repair any worn equipment, refill oxygen or cells, and update Beacons before you continue. Remember the related limitation: Collecting random salvage will not replace scanning actual fragments. On this original-Subnautica route, a sensible plan is more valuable than a fixed set of unverified coordinates. Use this chapter as a decision path for your own save rather than assuming all fragments and resources have been found already.
Organize unfinished blueprints in the PDA
Organize unfinished blueprints in the PDA is a concrete milestone in this survival route, not a command to rush to the next depth. Start with Early Blueprint Route. Use the Scanner on fragments to unlock necessary vehicle, tool and base technology. Explore Kelp Forest and Grassy Plateaus outskirts before pushing into deep zones. The most common failure here is specific: Collecting random salvage will not replace scanning actual fragments. Before leaving your staging point, review the equipment in your PDA, verify the depth of the objective and note which corridor you will take back.
