Prism tower (Red Alert 2)

The Prism Tower Was the primary Allied defense during the final part of GWWIII.

History
The Prism Tower was developed by Albert Einstein to counter the long term advantage of the Soviet Tesla Coil. The first deployment of the Prism Tower was at the Pentagon, as part of the defenses against the Soviet attack.The Prism Towers proved effective, as two prism towers close together could combine the prism beam and increase power by a little more than 2x. Multiple towers increased the power even more. In essence, this was done by firing off a beam of light energy, essentially a laser, at another prism tower, which would itself fire at the precise instant to create a more powerful beam of energy.

Description
The Tower consists of a rotating mirror on top of a tower. The tower fired concentrated beams of light, heavily focused by mirrors. A single Prism Tower shot was less powerful than that of a Tesla Coil, especially if it was charged by Tesla Troopers. However, the Prism Tower fired faster, and two or more Prism Towers in close proximity had the ability to combine their shots, as previously described, a property the Soviets did not possess.

Usage
They were erected around Allied bases to defend from Soviet attacks and are particularly effective against heavily armoured Soviet tanks. But artillery and aircraft were a threat to it.

In Command & Conquer: Red Alert (iPhone) these towers can still combine their beams to heavily damage enemies.

Because of the disappearance of Albert Einstein, the Prism tower is not seen in World War III. However, a different, but functionally equivalent version was made in its place - the Spectrum Tower
