File:Q2.png The Reactor is the main hub of the Strogg power plant - it houses the reactor core and connects with its supporting facilities. The area features huge skyscraper-like machines, large pools of coolant liquid, as well as a master switch, which can expose the reactor core. The map undergoes several major changes as the player progresses through the hub. First, the coolant liquid disappears, leaving exposed overheated machinery visible. In the final stage, parts of the level are flooded with toxic waste and the whole area becomes unstable, with periodic explosions and tremors.
