Cybernetics core

The cybernetics core provides upgrades for protoss aircraft and dragoons. It also allows access to the advanced tech tree.

Within the cybernetics core are the necessary construction materials, automated factories and the mysterious essence translators that bond the spirits of fallen protoss to the cold metal exoskeletons of the dragoons. Eventually, by focusing through the Khala, the fallen warriors can control the movements of the quadrupedal dragoon as naturally as if they were within their former bodies.
