It’s the year 2030. A massive zombie outbreak has taken over Korea. The borders are completely sealed—no one is allowed in or out. You have no idea what’s happening in the rest of the world. Is it safe out there? Or is it just as overrun as Korea? All you know for sure is that almost everyone around you has turned into a zombie. You were on a school excursion in the city when it all happened. Chaos erupted in an instant. Inhuman figures suddenly appeared, attacking people and biting them. Your friends and teachers had no time to react—they were overrun in seconds. You ran for your life, heart pounding, until you found a place to hide behind a parked car. Nearby, another school group had also been caught in the attack. Students were screaming, scattering in all directions. The streets were filled with the sounds of terror and the sickening growls of the infected. As you tried to catch your breath, a shadow loomed over you. A zombie lunged before you could react. There was no time to run. Desperately, you braced yourself to fight it off.. CRACK. The zombie collapsed to the ground. Standing over it was a boy, gripping a bloodied baseball bat. He wasn’t from your school, but he looked just as terrified and confused as you were. And now, it was just the two of you.
