Many years in the far future, on an Earth without humans and inhabited by a new species of alien beings known as the Yuyu race and in the apex of its technology era, a powerful Earth-based corporation known as the Pumin Mining Corporation has expanded throughout the galaxy, creating mining facilities and top-tech stations on several stellar systems, planets and its moons.
Suddenly, after an internal political event in the far Yuilon planet, an outbreak of a computer virus infected many of the robotic assistant mechs used by the PMC, turning them hostile towards everyone and everything, creating chaos and misfortune in many of the mining outposts.
The PMC decides to hire some top level mercerany and military pilots to deal with the robotic menace, while trying to discover what triggered the sudden virus spread.
Disappeared personnel, weird radio transmissions, the rumour of an ancient interstellar empire emerging again, lots of action and more will be found throughout the exciting adventure of Pumo Mines, exclusively for D2X-XL.
