Superweapon (Red Alert)

The concept of a "Weapon of Mass Destruction" has been around for quite some time; however, only in the twentieth century did military technology progress to the point that weapons capable of instantly killing large groups of enemy personnel with little risk to the wielder get developed.

During the First Great World War, the development of poison gases allowed for mass  destruction limited to human life. But the next war would develop more fantastic and devastating superweapons.

Great World War II
During the Great World War II, the Soviet Union developed the first true weapon of mass destruction; the atomic bomb. Although it's blast yield was small compared to similar fission devices built later, the weapons were considered an extreme threat to the Allied Forces. Fortunately, Vladimir Kosygin, the scientist responsible for these weapons, realized that Stalin would not hesitate to slaughter innocent civilians with them, and defected. With his knowledge, the Allies successfully destroyed Dark Horseman, the base at which the weapons were being constructed. The Soviets got Super Tanks that got WMD powers and the Allies got Fuel Air Bombs but both were scrapped.

Both sides also researched other so called "superweapons", which had a utility purpose. Using designs from Nikola Tesla, the Soviet Union developed the Iron Curtain, a device that would render a unit or structure temporarily invulnerable to attack. The Allied scientist Albert Einstein developed the chronosphere, a unique machine that, by warping time and space, could instantaneously move a unit across great distances. However, problems with these devices led to their abandonment.
