Underneath the town is an old, unused network of sewers. Thanks to the new sewer system, this area has been converted into a new training ground. It is a maze of metal, dirt, and filthy water. "Most" of the rats are gone, but some still run around. The immense echoing also deceives the location of moving creatures and can make you run away from the person you are trying to catch. This training ground is best for water and sound manipulators and teaches you to find the enemy in a maze type area.
