Are you in?

You lean into the box, and hear a very faint electronic beeping sound, similar to a countdown. You run back into the apartment and head to the fire escape. You open the window and jump out onto the escape. As your feet land outside the window on the escape, a huge explosion blows out the windows and sends you flying over the railing and down to the street below. You barely escaped certain death... and luckily you're on the second floor so the fall wasn't too great. As you stand and dust yourself off, you glance up and catch a glimpse of a shadowy figure at the corner staring at you. He notices you looking, and quickly corners the building, out of sight.
