Psychic beacon

The Psychic Beacon is a mind-control device developed by Yuri and used by the Soviet Union during GWWIII.

Great World War III
The Psychic Beacon interferes with the human mind. They make people who are within its range extremely happy, thus making them extremely suggestible. The Soviet Union deployed these devices across the United States in an attempt to convince the American population to join the Soviet cause. At one stage the Soviets even managed to cause the US President to defect by deploying one such device in Washington DC. However, there are some people who are naturally immune to mind control, notably US agent Tanya Adams and Professor Albert Einstein.

Psychic Dominator disaster
A second generation of Psychic Beacons, the Psychic Dominators was later developed by Yuri which was used by Yuri's forces in his campaign to take over the world. This generation of Psychic Beacons allowed total mind control over the target, in effect turning them into mindless slaves.

After the time travel, all Psychic Beacons were hunted down and destroyed by the Allies and the Soviets refused to deploy Mind control technology again after experiences with Yuri. This made sure Psychic Beacons were no longer produced after the Disaster.
