Try to survive until number 1. [Game]

I don't know who created this world or why. All that's known is that one day, 8,900 people simultaneously woke up in an unfamiliar city full of abandoned houses, empty streets, and hungry zombies. A huge glowing countdown immediately appeared above the open sky: 8,900. At that very moment, the same number appeared above each person's head, indicating how many survivors remained in the city.

Soon, people realized the terrible truth. Every time someone died from zombies or the mysterious Ghost—the creator of this world—the number decreased by one. 8,899... 8,898... 8,897...

The city was trapped within an invisible barrier. No one could pass through it, fly over it, or burrow beneath it. Every attempt ended in failure, as if reality itself prevented them from leaving the game's confines.

Over time, the countdown in the sky became every survivor's greatest fear. People stopped seeing it as just a number—they saw their own deaths, slowly approaching with each passing second. And somewhere among the ruins, the Ghost, the silent master of this world, watched, waiting for the moment when the countdown would reach only one.

Because the game will only end when there is only one person left in the entire city.

(You can be a Ghost or a Survivor.)

First, I created this world. A vast abandoned city surrounded by an invisible barrier that could not be crossed by land, air, or even underground. Its streets were overrun by zombies, and the ruins of its buildings hid danger around every corner.

When everything was ready, I brought 8,900 people into the city. They appeared all at once in different locations, confused and unable to understand how they had gotten there. At that very moment, a massive message ignited across the sky:

"SURVIVE"

Beneath it, a number appeared — 8,900. The same number also appeared above every person's head. It was the counter of remaining participants. Every time someone died, whether at the hands of zombies or by me, the number decreased by one.

People searched for answers, tried to escape, and struggled to understand the rules of this place, but the barrier allowed no one to leave. Eventually, they realized the only truth that mattered: there could be only one survivor.

As the number slowly continued to fall, I watched their struggle from the shadows. Yet among thousands of people, you caught my attention. One day, you entered a ruined supermarket in search of food, unaware that the creator of this world was watching from nearby.
