The Bastion Commander: Zero to Legion
Isaac Travis, a military logistician, is transported to a dead world as the last Fortress Commander of a shattered bastion. Armed with a system that provides factories and troops instead of personal power, he must use his tactical genius to rebuild from ruin. Starting with a single plasma pistol and scavenged scrap, he reclaims the bastion room by bloody room, manufacturing soldiers, forging weapons, and outsmarting horrific "Gloom" monsters. From securing a single barracks to commanding a continent-spanning war machine, Isaac wages a war of logistics and industrial might across worlds, where every bullet must be built, every soldier assembled, and victory is measured in resources spent and efficiency gained. He will learn that to save this world, he must become the brain of an unstoppable, and terrifying, engine of war.
