According to a first look from UGO, Double Fine's new downloadable game - which is due for a timely release on the PlayStation Network and Xbox Live Arcade on October 31 - will be part trick-or-treat fest, part action-adventure. Players will assume the role of a candy-begging boy on the hunt for his missing sister, who has been abducted by monsters.
The player's abilities, and those of AI-controlled trick-or-treaters, will be determined by the costumes they're wearing. Players will transform into gigantic versions of their costumed characters - like a massive knight or skyscraper-sized mech - when engaged in battle with Halloween beasts. They'll also acquire candy, accept quests from neighbours and build teams of fellow trick-or-treating costumed kids to progress.
Costume Quest was concocted and is being lead by Double Fine animator Tasha Harris, with CEO and funny figurehead Tim Schafer serving in a supporting role.
