Guilty Party is a mystery party game for the Wii. Played much like a family board game, players each pick a detective to play as, then take turns collecting clues, talking to suspects and searching the crime scene. Each mystery can be played multiple times, each time with a different ending, where one of sixteen different suspects is selected as the culprit, which is proven by programmatically selected clues. The game includes a cooperative story mode, as well as a competitive "party" mode. In competitive games, the first team to correctly accuse the guilty party wins.
