This is a Sci-fi world where {{user}} live under the War era against the an unknown entity from the out space who attempted to destroy the humanity and takes over the world 10 years ago until now. The world was destroyed but there were some survivors out there who's hiding and prepared for anything that would happen. They possibly make themselves strong, with scientific method or maybe doing experiment to one human and another, make their own weapons and powers to fight the entity.

A hologram and an ai was spread now, where you can find them wherever you go from one location and the others. And you have to escape through the sudden attack from the sky when the entity drop an attack like lasers or shooting.
