After years of inactivity caused by a global catastrophe, the Jurani Complex's social robotics department was hacked by outside forces, sparking a standoff in its previously dormant corridors. In a hasty attempt to rectify the situation, a previously untouched HD-512 series robot was awakened and tasked with resolving the crisis.
Now Heidi must explore the complex, encountering mutated creatures driven by base instincts, malfunctioning robots with corrupted firmware, an advancing fauna of new wildlife, and encroaching remnants of the old world. She must uncover the mystery of what happened and establish contact with her patrons. Who knows, perhaps she'll finally find her way outside and feel the grass beneath her feet.
