Subnautica: Below Zero: Where to find Ion Cubes

Ion Cubes are a type of synthetic crystal that contain massive amounts of energy in Subnautica: Below Zero.

Created by the Architects, their energy is equivalent to a small nuclear detonation when they are considered to be in a stable state. The Architects were highly advanced beings, said to have inhabited Planet 4546B a thousand years prior.

There are several Ion Cubes available in Subnautica: Below Zero. Each plays an important part in crafting and upgrading specific items. The glowing green cube is easily identifiable for those searching.
