Subnautica: Below Zero Blueprints: Data Boxes and Fragments

18 data boxes sit at fixed spots and each unlocks one blueprint. Other blueprints unlock by scanning fragments, and the scanner rules in the files say how many pieces each one needs.

All 18 data boxes

13 different blueprints; 4 of them are in more than one box. Each row opens the box on the map.

Fragment scans: 43 blueprints

Scan a fragment with the scanner until the number of pieces in the second column is reached and the blueprint unlocks. The last column counts the fixed placements of that fragment in the game files; the files place 340 fragment markers in all, for 30 of these 43 fragment types.

Only the fixed placements are in the files as positions. The rest of the pieces a blueprint needs are random per new game: the game rolls them from its spawn tables, so no list of their spots exists. For the chance of a resource in an area see the resource chances; fixed fragments are on the map.

The Light stick fragment needs 1 piece and the files place many copies of it; the Architect Component rows share one marker name in the files, so their counts are one pool.

Single-scan unlocks: 81 more

Scanning these once unlocks the blueprint named. Taken from the scanner rules in the files.

About these unlock rules

Data boxes are fixed objects in the world; their blueprint and position come straight from the placements in the game files. Fragment rules (pieces needed, scan time, blueprint) come from the scanner table in the files. The recipes themselves are on the crafting page.

NOT VERIFIED: which blueprints you start the game with is not part of the data read for this page. Depths are metres below or above sea level as stored for each marker.
