Ion Cubes are among the most valuable resources in the game. They are used to:

Found deep within alien facilities like the Quarantine Enforcement Platform and the Primary Containment Facility, Ion Cubes represent progression, danger, and discovery.

Nothing says “end-game explorer” like carrying Ion tech.
