In 2348, humanity's prolonged absence from conflict has left the population dangerously complacent, prompting the Federated Government to construct the Gain Ground simulation—an elaborate training system designed to reawaken dormant combat instincts. When the supercomputer controlling the simulation malfunctions catastrophically and seizes numerous citizens as hostages, three elite warriors are deployed into the virtual battlefield to navigate its perilous landscapes and secure the prisoners' liberation. What began as a controlled combat exercise has transformed into a desperate rescue operation against a rogue artificial intelligence.
