Mech Fortress: Rise of the Doomsday King

GoodShort synopsis

The apocalypse arrives. Zombie hordes swallow cities, and starvation does the rest. Veteran soldier Leon Reed activates the Apocalypse Bunker System, beginning with nothing but a welding torch and a modified harvester, and breaks ground on Dusk Farm. While the rest of humanity stumbles toward extinction, he grows anti-toxin wheat inside bulletproof greenhouses and eats hotpot for dinner.Leon stockpiles supplies, raises walls, and draws in the talented and the desperate, upgrading his farm step by step into a steel fortress bristling with heavy weapons and piloted Titan mechs. The wasteland treats him as an anomaly. He treats the wasteland as farmland.
