Platform Zero

Lim Jinwoo finds himself trapped in a subway station he's never seen before. As monsters begin hunting trapped survivors, Jinwoo meets Suyeon and Sangjoon, and they must fight their way to escape. But during an attack, one of the creatures tears out Jinwoo's eye. But people who are injured by the monsters eventually become monsters themselves. Jinwoo soon realizes that his eye is beginning to change, but if someone leaves the station before transforming into a monster, their body returns to normal outside. Will they make it out alive or will it be too late?
