Age of Rust: Machine Distortion

The unknown distortion code not only invades global networks and robots, but also invades human bodies through acid rain and airborne transmission. Dead people will be transformed into rotten zombies; living people's bodies will also be slowly eroded by trace amounts of viruses, and wounds will easily mutate and fester. The world has become a double desperate situation: outside, there are deformed iron skeletons controlled by the mastermind hunting the living people, and in the dark, there are hordes of zombies entrenched underground in the buildings. The steel monsters and walking zombies are mutually exclusive, but together they force the survivors into a desperate situation.
