Urbex is the exploration of old abandoned buildings and man-made structures. Sometimes this involves trespassing leading to possible arrest and even jail time. It's also extremely dangerous in that buildings are often unsafe containing chemicals, looters or electrical hazards. Your best friend, Stinger, asked you to help him explore an abandoned factory. Being intrigued by these old buildings you agreed to join him. The key to the entrance door is somewhere hidden behind a rock. Find it and use it to enter the factory. Stinger should be somewhere inside the factory.
