This StarCraft 2 unit guide will cover the Terran Tech Reactor add-on building. The Terran Tech Reactor is new in StarCraft 2: Wings of Liberty, along with the Reactor and Tech-Lab serving as universal add-on buildings to increase the capabilities of the Barracks, Factory and Starport. The Tech Reactor combines the functionality of both the Tech Lab and Reactor into a single add-on, that when the benefits are considered, is quite possibly the best upgrade in the campaign, where it is available, unlike in melee where it cannot be constructed. The Tech Lab allows all units normally unlocked by the Tech Reactor to be built at the attached facility, while also allowing all units to be produced 2 at a time, and expanding the total queue of the production facility to 10 slots.
The Terran Tech Reactor is unlocked in the StarCraft 2: Wings of Liberty campaign by using 25 Protoss research points to unlock it in the Hyperion laboratory. Finishing the Prophecy missions as soon as possible will fast track players to owning the Tech Reactor, and utilizing its functionality in more missions. Choosing this upgrade will lock-out the ability to choose the Orbital Strike upgrade.
