The aftermath of the Great War scarred the world
with a terrible legacy: the Lost Tech.

Caches of powerful war machines buried beneath the earth,
forgotten after the end of the conflict.

Because of the terrible history of these weapons,
the Kingdom of Artemisia refuses to seek out or use them.
However, one commander, Major Nathan Gries, begins to believe
that the only way to keep the world safe from the Lost Tech is
to locate and secure them, to prevent them from falling into enemy hands.

Then one day, he receives an emergency message:

"Emergency transmission from the White Fangs.
An unknown signal has been detected
beneath the Northridge Alps--"

Faced with Lost Tech, Major Nathan Gries,
Lord General Isoroku Tsukumo,
and Wolfram, leader of the White Fangs,
will face a new test.
