โ€œOpen or Dieโ€ basically means if you canโ€™t open the door youโ€™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 Iโ€™ve heard this before.
