Here is a basic layout of the expo. We are basically still at the entrance, but we won't be able to get out going towards the entrance. We need to head deeper inside and escape to the back. However there will still be civilians in danger inside the expo. Aeron is going try to save as many as possible while trying to escape from the back as well.
Outside the circle is all parking Inside the circle is the amusement park area Then you have the expo that is the square.
