Run upstairs to the upper floors.
From Create Your Own Story
You turned in the direction of the flights going up and sprinted, hiking up your skirt to allow your legs to stretch upward minimal hindrance. You can see the floor numbers as you ascend: two, three...five, ten. Even though you're a good runner, sprinting up over ten flights of stairs is making you exhausted. You stop for a moment to pant for breath, your clothes and skirt sticky with sweat. Far below you, you can hear distant shouting and pursuing footsteps echoing in the staircase.
No time to rest now, you thought to yourself as you push your sore aching body up the stairs. Thirteen, fourteen...sixteen. Finally, you reach the twentieth floor with no more stairs going up and a single, metal door in front of you. This seems to be the top of the building. You turn your head down the flight of stairs and hear the faint, echoing shouting of men getting closer. Apparently they have already took notice of your escape route somehow. You quickly push the door open and rush onto the rooftop. You look around to see that it is mostly bare except for a few potted plants and bulky, metallic generators humming away. There's nowhere to hide.
You hurry over to the edge of the rooftop and leaned over. About three hundred feet down below, you can see small dots of people moving in around on the concrete parking lot.
