“Open or Die” basically means if you can’t open the door you’re gonna die. Where am I? I have a terrible headache because of the smell of chemicals. What happened yesterday? Some people in black kidnapped me for a reason. It looks like a closed laboratory. I opened the report on the desk. It looks so old. San navarro lab in Alamagordo...I think I’ve heard this before. (그래! 이제야 기억이 났다. Alamagordo의 San navarro 연구소! 인류최초의 핵실험이 있었던 곳! 아니, 내가 왜 여기에 있지? 문밖에서 소리가 들린다. 소름끼치는 음성. 그리고 발자국 소리는 분명 사람의 것이 아니다. 본능적으로 도망쳐야 한다는 생각이 들었다. 복도로 뛰어나갔다. 뒤를 돌아보니, 오 마이 갓! 나를 쫒아 오는 것들은 좀비였다. 문을 열지 못하면 죽는다. 열어야 산다!)
