Story Background
In year ×× of the Space Calendar, the explosion of a supernova was observed, accompanied by a large number of iron cells (corrosion cells) that flew in.
These iron cells eroded the hards on the ground, causing them to go berserk one after another.
As the city's functions gradually paralyzed, industrial hards began to attack people.
Finally, an anomaly occurred in the city's central computer, causing even military hards to start going berserk.
Humanity came close to extinction.
The Violent Soldier
It was decided that the Violent Soldier, created by the secret bio-weapon development project (the Violent Project), would launch.
While defeating the hards that have gone berserk, the Violent Soldier set out on a journey to explore the mystery, heading toward the exploded supernova.
Stage 1: Mecha City Zone
The great explosion of a supernova brought about the advancement of corrosive cells, leading to the destruction of even highly developed civilizations.
A world dominated by new creatures born from the repeated fusion of remaining mechanical units and Iron Cells spreads out, with humanoids blocking the path.
Stage 2: Gas Cloud Zone
Iron Cells have multiplied extensively in the atmosphere, creating a thick gas cloud that fills the area.
A giant biological battleship appears in this Gas Cloud Zone.
Stage 3: Scale Zone
As you advance through countless writhing fibers, creatures with hard shells appear one after another in the Scale Zone.
Stage 4: Cosmo Zone
A meteor shower was detected as the next threat arriving after the Iron Cells.
We immediately fly off into space to destroy everything in the Cosmo Zone before it reaches the planet Earth.
Stage 5: Mega Zone
The enemy's main fleet has initiated a total attack.
You must skillfully dodge the enemy's bullets attacking from four directions to get through.
The objective is to clear the Mega Zone, which is composed of a pipe maze.
Stage 6: Bio Zone
Having pinpointed the location where the enemy's main fleet was lurking, the soldier immediately headed for the final battle.
The form of the enemy seen there was a giant ship functioning of its own will.
We will break into the Bio Zone with the battleship and destroy the enemy's central section.
