Oppressive Regime and Surveillance The government of Elysium, represented by the character Secretary Delacourt, utilizes powerful robotic enforcers to maintain order and strictly control who is allowed access to Elysium. Surveillance technology pervades both Elysium and Earth, exemplifying an advanced, oppressive state that employs technology to monitor and pacify the populace.

The Rebel Group

It involves significant action sequences, including the use of helicopters and advanced weaponry, showcasing a fierce confrontation as they aim to disable the defense systems and bring equality to the divided world.
