The Control Room is where the Hunger Games are operated by the Gamemakers. From here they monitor each tribute's status and location, and decide who to focus on for the cameras. They can alter the arena environment by changing the time of day as it appears to the tributes, adding muttations, starting fires, etc. In the film version of The Hunger Games the Control Room is seen just before and at various points during the 74th Hunger Games, most commonly when Head Gamemaker Seneca Crane directs his subordinates.
