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.

"We are delighted to work with the creative genius of Tim Schafer and the entire Double Fine studio," said Martin Good, Executive Vice President, THQ Kids, Family, Casual Games, and Global Online Services. "Delivering high-quality content across a variety of digital distribution platforms is an important growth initiative for us, and we are pleased to do so with two titles whose potential appeal could encompass both hardcore and casual players."

Tim Schafer, founder & CEO of Double Fine added, "We wanted to make a big impression with these, our first downloadable games ever. So we are coming out swinging with two great adventures from two of the most creative minds in the company."
