Costume Quest is a rollicking Adventure/Role-Playing game that unfolds on Halloween night across seemingly peaceful suburban neighborhoods, a mysterious village carnival, and a monster-infested shopping mall. Created by Double Fine's lead animator, Tasha Harris, the game follows the adventure of a group of young friends who must rid their neighborhood of monsters using only their wits, their bravery, and their home-made costumes. Players go door-to-door collecting candy, points, cards, battle stamps and quest assignments as they prepare themselves for Combat Mode — where they transform into larger-than-life versions of their costumes. Each costume that comes to life provides its own unique set of superpowers that players will need to battle Halloween's worst monsters.
