The Allbright System - A Sci-Fi Progression LitRPG Story

Thea dreams of joining the United Human Federation marines, a childhood ambition forged when soldiers rescued her from Lumiosia’s Undercity. But escape requires credits, and the only path she knows is the arcade—repairing old machines by day, dominating simulators by night. When the monthly ladder reset arrives, a new challenge materializes without warning, its origins unknown and its stakes unimaginable. Suddenly thrust into a galactic conflict governed by the enigmatic Allbright System, Thea discovers war is no longer fought with mere ships and rifles. Each faction receives a unique System trait, twisting the rules of combat in unpredictable ways. For a gutter rat with nothing but grit and a stolen marine’s legacy, survival means outplaying empires that have waged war for millennia. The galaxy’s fate hinges on a single question: can an undercity girl master a System designed to break her?
