When global bombings orchestrated by a terrorist named Nigel shatter civilization, the world transforms into a lethal game governed by red zones, green zones, and predatory monsters. Survivors receive indestructible phones displaying levels, stats, and randomized unique abilities. Yet the system’s darkest rule is its most rewarding: killing a fellow human instantly steals all of their accumulated experience points. When slaughter erupts across his high school auditorium, Lucas—a detached, mature student shaped by tragedy—refuses to panic. Fleeing the carnage to secure food and chef’s knives from the cafeteria, Lucas prepares to make whatever ruthless choices survival demands.
