Reactor
The Reactor is a late game upgrade based building. It shares some similarities with the Lab, but one of its upgrades, Plutonium Extraction, expands a unit instead of increasing their stats by allowing the Missile Silo with its deadly Nukes to be constructed. The Reactor itself is vulnerable and slow to upgrade, but carries a lot of potential with nuclear energy.
Production
The Reactor can initiate the Plutonium Extraction and Titanium Refining upgrades.
Obtaining
The Reactor is built by the Private after the Hangar has been built.
