In the year 2020, humanity faces a crisis as Earth is attacked by unidentified monsters. Players prepare for the attack by challenging the Labyrinth that appeared. They can choose four options:

Easy Mode, where anyone can survive; Normal Mode, where you must work to survive; Hard Mode, where only 1% could survive; and Solo Mode, the harshest difficulty.

Kang TaeSan, the strongest Easy Mode player cleared the Labyrinth using an unconventional approach and acquired skills others could not: [ Addition, Multiplication, Attack Nullification, Ultimate Judgement...].
