Apocalypse Core Books in Order

When the World Core destroys civilization and rebuilds it as a deadly game, a survivor relies on martial arts and an unusual Chi ability. He gathers allies while learning the rules of a world designed for combat.

The World Core's next trials pit a team of survivors against dangerous plants, mutated rivals, and a ticking clock. Their leader must exploit his unusual Chi skill to strengthen the group before the challenges overwhelm them.

A survivor and his companions face new trials that could grant extraordinary Chi power. A final tournament against the world's strongest remaining competitors awaits, and even winning may carry a price none of them expects.
