Mech Fortress: Rise of the Doomsday King - Episode 5

A man arrives seeking help to fix his modified harvester designed to fight zombies, but others doubt its durability against heavy enemies. The mechanic inspects it, pointing out weak welding and the risk of cracks under stress, then challenges the man to prove the machine's worth in ten minutes. The man quickly upgrades the harvester with a crash beam and torque adjustments, demonstrating its power by effortlessly slicing through a large rock. Despite his skill, the group remains uncertain about trusting him, leaving his acceptance and the machine's future use unresolved.
