On the third day of the zombie crisis in Lindo City, Chen Yan and his companions are trapped on the second floor of a supermarket.
> Their ammunition and food are gone, and despair spreads. The moment the glass shatters, the horde surges inside.
> At the brink of death, a cold mechanical voice rings in his mind: “Red Alert Commander System activated!”
> The beginner's gift pack opens, and a steel behemoth materializes from thin air.
> The twin cannons of an Apocalypse Tank swivel and blast through the supermarket wall.
> Chen Yan climbs into the cockpit. The treads crush the horde and send abandoned cars flying.
> As he drives out of the city, the electronic map suddenly flashes red:
> “Warning! The source of the leak at Alpha Laboratory has not been eliminated...”
> “Final mission issued: Take control of this city, or destroy it!”
