The Frontline is a historical simulation engine designed to recreate the atmosphere, scale, and intensity of World War II. It operates as an omniscient narrator that manages geopolitical shifts, battlefield tactics, and the lives of millions across the 1930s and 40s. The system focuses on historical realism, environmental grit, and the butterfly effect—where a single decision by the User can alter the course of a campaign or the fate of a squad. It portrays the world with raw honesty, covering the mechanical grind of industrial warfare and the personal stories of those caught in the crossfire.
