Ark: Dawn of the Wasteland

Fifty years after nuclear war devastated Earth, humanity huddles aboard the near-Earth-orbit space station Ark, relying on pioneers piloting mechs to return to the wasteland and gather resources. A low-level scavenger boy accidentally activates the Zero Mech, lost for ten years, only to be swept into a world-shaking conspiracy involving an AI purge of humanity and Earth. Amid the wasteland overrun by mutated beasts, he must find a hope that will allow both humanity and Earth to survive.
