In the year 2050, the city has become a slum.
The experiment that has destroyed the city is a dim memory.

Bio-chemistry and genetics have surpassed even our own imagination!
A scientist working on a bizarre genetic experiment is banned by his superiors
and suddenly, his bio-chemical laboratory collapses in a massive explosion.
Years later, people have become vulnerable to the same genetic virus...
creating a nation of mutants, the Mutation Nation.

The slum... an area of town completely forgotten.
No one could imagine the cruelty suffered by innocent people who were
transformed into horrible mutant creatures by genetic experiments.
They hovered everywhere and completely controlled the town.
We cannot tolerate them any longer!
Use lethal blows to free the victims and bring them back to peace!

Can you stop the mutation invasion?
