Defend the world on a battleground
where time has collapsed!
Despite two galactic wars fought to achieve dominance,
humanity remains divided into seven factions.
In order to continue warfare,
mankind has begun constructing a new artificial battlefield,
the battle territory.
There, the battle to determine who will rule the stars,
known as local warfare, is set to commence.
The seven factions in the Heliosphere send pilots (Stringers)
and combat bio-machines called VA (Vital Armor)
to the battle territory via dimensional transmission.
However, during a final experiment,
mysterious photon beings called "Non-carbides"
appear on Jupiter's moon Callisto,
halting the flow of time in the battle territory.
As the area affected by the time stoppage expands,
the Heliosphere Management Committee (HMC) orders
the seven factions to dispatch their elite units
in order to eliminate the Non-carbides.
A battle to restore time is about to begin──
