Fragments are broken pieces of advanced technology that can be analyzed by the Scanner to create Blueprints. They are found in and around Wrecks, strewn across many Biomes around the Aurora, and scattered throughout the Degasi Seabases. Depending on the technology being analyzed, a different number of Fragments may be required to acquire the blueprint. Scanning a Fragment for which the player already has a complete blueprint of will convert the Fragment into two pieces of Titanium.

  • In the past, Fragments could be picked up and had to be researched using the Fragment Analyzer. This system was scrapped with the introduction of the Scanner.
  • By using Console Commands, it is possible to spawn in fragments which when dropped, will become a black cube.
