Colossus: The war never ends

After the anonymous assasination of various world leaders, hell broke loose and took over the earth. The third world war lasted for five years, almost leaving the world in ruins, ashes of amity burned as thousands of the innocent lay bloodied on the streets.
Before long, the war itself broke the boundary between science and sanity when a country created a weapon out of a young girl.

Victorious battles were led by the child and it was not long before her existence errupted an even more vicious bloodshed. More of them began appearing, and they were most certainly not human anymore, they were fast, strong, at times undetectable as they were savagely hacking and slashing through armies. But they remained as secrets known as "Colossus" experiments.

As new leaders began to arise, peace was gradually restored until the world was walking back on track. But in the shadows of ressurecting nations was the grim secret of why nuclear weapons were not utilized during the war, and how a small island, defeating a whole armada, started a macabre quest for glory.

The new leaders were now after the Colossus experiments, but the reason remains a secret still.
