As you continue down the tunnel, you notice the walls and ceiling becoming increasingly slick with moisture. The stench of decay grows stronger, and you have to cover your nose and mouth to avoid retching. Suddenly, you reach an intersection where the tunnel splits into three different paths. The first path leads to a dead end, with a pile of rubble blocking any further passage. The second path is partially flooded, with murky water up to your ankles. The third path appears to be clear, but you can hear strange noises coming from further down. The hairs on the back of your neck stand on end, and you realize that danger may be lurking ahead.
