Battle Bots (2018)

Planet Earth, 2039: The superpowers of the world have destroyed the continents with nuclear warfare. The New Order, a fanatic cult with a pseudo-scientific fixation on large robots that had been previously used to mine the center of the Earth, rule the surviving population with a doctrine of militaristic slavery. An opposition group, The Fighters, live like scavengers and avoid the New Order's death troops while plotting how to overthrow their reign of terror.
