Underground War Chronicles

Synopsis

A robot action shooter.

In the year 2029, humanity faces a hostile force on Earth.

Nestled beneath the surface and evolved into countless varieties, this threat originated from a single artificial lifeform created by humanity itself.

Countless battles have been fought throughout history, but as the enemy forces grew ever stronger, humanity deemed further expansion too dangerous. They made the decision to deploy an experimental humanoid weapon still in development—the HD-01, commonly known as Heavy Doll, Granbauer—into actual combat.
