People call it the D-Day, the apocalypse where humans' lives were collapsing by a nuclear reign.
But those peculliars remained as the survivors, made a life choice among the factions.

Dawn Guards : The faction where humans are reborn to be enlighten and directed from losing in the darkness. They're trying to protect people's hope and strive to a sincere peace.

Alpha Corp : The faction where humans are reborn to rule the world by any ways possible. They're eager to take control of the potential world, including humans' lives.

Conflict is inevitably rising between these factions. They can't stand to stop the ShellFire, to seek for a timeless peace in humanities for living their lives.
