Here's a guide of all the preludes, if you need any help!
1. Talk to the woman at the start.
2. Face the lady in front of the camera (Rita), and click her to start.
3. Next you have to get a tape from the shelves behind you, and click on the screen with the crow, then go back to Rita.
4. Next you'll have to select a monitor to speak with Maya, then go back to Rita.
5. Next, check in with the two guys on your right lounging around, then go back to Rita.
6. Next, check in with the weather guys directly behind you. Then, go back to Rita.
7. Next, talk to the crow. You have to wait until a caller stops talking, then go back to Rita.
8. You'll lose power, and need to wait for someone to come into the room. Talk to them.
9. Select Rita, then click the monitor when you hear static.
