Here is the game overview provided by Bandai Namco:
“I’m with you. Alone, but never really alone. Pilot your armoured vehicle with your partner Magus as you scramble for limited resources in this PvPvE third-person shooter. No experience is the same. In this ever-changing landscape, you must develop a close relationship with your Magus to survive in this unforgiving wasteland. The two of you, alone, on a one-of-a-kind journey.”
The story tells the tale of Alba Kuze (voiced by Yuya Hirose), a Drifter, who scavenges earth’s resources such as AO Crystals by piloting All-Weather Mechanical Bipeds called Bowie Rabbit with the help of Magus named ADA (voiced by Yui Ishikawa), a humanoid robot equipped with AI throughout his mission.
