THE AGE OF COLOSSUS.
The Inquisitor Meteor Shower in 2054, the meteor shower that once predicted to bring the end to Earth, had change the Earth from a civilized world into a world of endless wars and destruction.
The fallen stars from afar carried a mysterious substance only known as the "Titan's Blood", was the core of the endless conflicts. A substance that can affect organisms with special gene sequence named as "Prime Code" and turn them into gigantic mutants known as the Colossus - a weapon of world domination, able to destroy cities and modern military with ease.
Since the substance was being recognized by the world, the extreme ambitions to control the world through brute might had risen around the world. The endless wars begun to scramble for these valuable military assets and races to create a largest army of towering juggernauts. The world is no longer same as before, it's a world of war and destruction. It's the Age of Colossus.
The most influential military organization on Earth that control the entire European continent with the might of their human Colossus and their disciplined Auxiliaries.
A faction that expressed obsession on experimenting the effects of Titan's Blood on other type of organisms and tested their destructiveness on civilians - Their behaviors without any ethics had earned them a notorious nickname name, Beasts of Terror.
Probably the only faction that haven't abandon the technologies and science from the older times, the Fusion faction equips their Colossus with advanced technologies derived form those in older times.
Gangs of free-roaming Colossus that fights for nobody else but themselves. These freelance Colossus groups might not have the best material support from the powers, but they are the most adapted people of the new age who knows most what is the meaning of "natural selection".
Religiously bonded military alliance in Asia which regarded Colossus as deities and avatars of supernatural beings. Their alliance are composed of three Colossus-ruled empires.
Probably an very insane idea... Anyways, I'm not totally taking this idea very seriously -
since I already have a even better project.
