The Earth's Chosen Savior

The Earth has a message for all of its inhabitants: the world is ending in 42 days, and monsters will bring about the apocalypse. Game studio employee Jeong-U Park is selected by the Earth as someone who can save the planet, but he must first survive in a world where people are now killing each other for power. He also must compete with other saviors to retain his planet-saving abilities. As doomsday approaches, can Jeong-U become the savior the world needs?
