MARCUS FENIX. WAR HERO. LOYAL SON. TRAITOR. Ten years after Emergence Day, as the Locust Horde advances on humanity’s last defended area—Ephyra—in a bloody war that has seen billions die, Marcus Fenix does the unthinkable: he defies orders and abandons his post during a critical battle in a bid to rescue his father, weapons scientist Adam Fenix. But Adam is buried in the rubble during a ferocious assault on the Fenix mansion, and Ephyra falls to the enemy. Marcus, grieving for a father everyone believes is dead, is court-martialed for dereliction of duty and sentenced to forty years in the Coalition of Ordered Government's brutal maximum security prison, known simply as the Slab.
