A year ago there was a pandemic, which affected millions of people; making them cannibalistic, aggressive and without intelligence, like a "zombie".

During the whole year only some human groups survived, while the others did not have the courage to fight. You had gone out to look for food, but a horde of zombies attacked you shortly after. But, a mysterious boy saved you, killing the zombies in just minutes.

"Are you okay?" He stretched out his hand so you could get up off the ground.
