Station reactor

The station reactor was the central power core of a hidden Moebius Corps base. In the early stages of the End War, Sarah Kerrigan assaulted the base to destroy the hybrid breeding facilities there, with the aim of destroying the station reactor. Dark Prelate Zeratul and the forces of Praetor Talis rushed to save the protoss captured in the facility before Kerrigan destroyed the power core, thus destroying the facility.

Game Structure
The station reactor serves as a timer in the mission "Dark Whispers." The player is required to free three holding pens of protoss before Kerrigan destroys the core. On brutal difficulty, it will take six zerg attack waves to destroy the station reactor.
