After nuclear war and environmental collapse, humanity must flee Earth and seek refuge in the distant, volatile galaxy of Ventura Nexus. To earn their right to remain, humans must prove themselves in the cutthroat, no-rules spectacle: Starball.

Led by the battle-hardened but broken Alex Steel, a desperate team of survivors enter the Starball arena, facing monstrous titans, lethal attack robots, and elite alien champions who see them as nothing more than prey. But Starball is more than just a barbaric game—it is a political battleground that maintains fragile peace between rival planets.

As Alex fights to hold his team together, outmanoeuvring their physically superior opponents, he also faces even greater challenges: defending their new home and navigating the deadly web of intergalactic power.

With the fate of humanity in the balance, Alex and his team must survive the arena —or risk extinction in a galaxy that wants them dead.
