When the town of Hamelin is saved by a mysterious Piper, but the townspeople don't thank him and he doesn't do much as revenge towards them, Grimm decides to crank the plague up a notch or two! Join the Pied Piper as he wanders through the outskirts of Hamelin, Hamelin's town square, the local docks, the riverfront, the Family Celebration Day festival, and the Piper's mountain hideout. Better pay the Piper; you've put up quite a bill! Source: Wikipedia, "American McGee's Grimm", available under the CC-BY-SA License.
