Mastermind (Yuri's Revenge)

The Mastermind is a Yuri mind control vehicle in Command & Conquer: Red Alert 2: Yuri's Revenge.

Background
Yuri's specialists wanted to create a powerful tank-like weapon system to achieve some sort of parity with Allied Prism tanks and Soviet Apocalypse tanks. Since Yuri's speciality was mind control, the result was a massive bio-engineered brain mounted on an armoured tank-like chassis able to rapidly mind-control all enemy units near it. The brain was designed to continuously mind control all enemy units within range so as to cause mayhem in large enemy formations before or during an attack. One fatal flaw in the design however, due to the contingency of war, new more powerful cyborg-electronic circuit systems are not ready in time for the Dominator Disaster War, forcing Yuri's engineers to make do with an adaptation of the design used on psychic towers which are too weak to fully realise the potential of a brain this powerful. As a result, whilst the Mastermind is theoretically able to control more units than the psychic towers, it cannot do so without sending its electronics into overdrive, leading them to overheat and eventually burn out, frying the brain and destroying the vehicle.

The Mastermind was erased after the Soviets meddled with the space time continuum.

In-game
The Mastermind is particularly deadly when deployed in the middle of enemy forces where they can cause mayhem in the enemy ranks. This ability makes it potentially devastating to an otherwise unstoppable armoured column before they make their mark on the battlefield. One major weakness with this weapon system however, is its lack of self-defensive armament. This makes it completely helpless against units immune to psychic control such as Terror drones, Robot tanks and air units when airborne. As mentioned above however, its greatest weakness is that it is prone to burning out when it has too many units under its control. This led to the tactic of rushing the Mastermind with many cheap and fast units such as conscripts, flak tracks or IFVs. Paratrooper conscripts are ideal for this task as they are both free and plentiful. Yuri's Masterminds can control up to 3 units each without going into overdrive.

Trivia

 * According to the concept art for the Mastermind, the scaling of the vehicle shows that the brain is twice the size of a tank.
 * It is possible to lengthen a Mastermind's lifespan indefinitely even when it has mind controlled too many units by means of IFVs with Engineers inside them to repair it. Note that the Mastermind needs to be completely surrounded by these IFVs, leaving either party vulnerable to enemies immune to mind control (e.g. Terror Drones and Robot Tanks).
 * It was considered to return in Red Alert 3 as a Soviet hover tank, but did not pass the concept stage.
