Imagine that you are a businessman and you have decided to start a factory in this abandoned area. You go to inspect the site before making the final decision and you realize that the place is extremely polluted and it is not safe to be there for too long. Your car tires have gone flat and just then you notice a truck. Unfortunately, you cannot find the key inside the truck and you cannot drive it away without the key. So now you must start searching the surrounding areas to find the key that you can use to drive the truck and escape from the polluted area.
