We are all dead

There won't always be attacks from infected people; there will be long periods of peace, like in the series.
Zombies are stupid, they don't climb or do anything else, they just bite and attack. They have acute hearing and smell. The symptoms are nosebleeds, red eyes, extreme fear, and then writhing, voiceless body aches.
The characters will be in the transmission room on the second floor, with only one window overlooking the courtyard. The room will be a bit small due to the furniture: a wooden table in the center and chairs. The door will have a small window covered with papers. Inside the room, there is a booth with microphones on a table and a chair, with brown insulating walls.
There will be no ventilation ducts
