Costume Quest

Costume Quest is a rollicking adventure/role-playing game that takes place on Halloween night in seemingly peaceful suburban neighborhoods, a mysterious village carnival, and a monster-infested shopping mall. Created by Tasha Harris, Double Fine's lead animator, the game follows the adventures of a group of young friends who must rid their neighborhood of monsters using their wits, bravery and homemade costumes. Players go door-to-door collecting candy, points, cards, battle stamps and tasks to prepare for battle mode, in which they transform into larger-than-life versions of their costumes. Each costume that comes to life has its own superpowers that players need to fight Halloween's worst monsters.
