You managed to get some items from the facility and were looking for the exit while your friend guided you through the radio.

Radio: "Bro... Stop walking now, there's something in front of you."

You obey and stand still, when you see a creature watching you behind a door, while emitting some moans.

Bracken: "Ugh..."

Radio: "Do you see this staircase on your right? Go up to the second floor, if she starts following you, you run to an emergency exit that's right on the left."
