Unknown Device

Unknown Device is a mysterious Ancient artifact that can't be crafted manually.

You find it in the secret chamber in Dark Cavern mission (on the first Garden planet). Reaching it will require a Spider Microsphere or Precursor Microsphere.

It can be either crafted into Atom Smasher (warning: very costly) or extracted (warning: it takes a very long time: with Extraction Lab, 49 minutes with Extraction Lab MKII, 11 minutes with Quantum Extractor).
