Urban Paranoia is a game which blurs the line between players and pedestrians as a way to provide fun for everyone.
Urban Paranoia uses a combination of large numbers of players and an play environment dense with non-players to blur the line between participants and non-participants. Players wear a small (8.5" x 5.5") piece of paper on their back which is the only indication that they are playing. They then seek to identify other players, and if that player is on an opposing team, take note of their number which they text in to score. The game turns upon the tension of not knowing if any of the people around you are playing or not, and upon the fact that opposing players score almost exclusively when you can't see them.
The game fosters a sense of low-level paranoia as players try to identify who is in the game and who is simply a pedestrian without being so obvious about it that they give away their own status. As players are only ever vulnerable from behind the game tends to generate a near-constant need to check over your shoulder. Just in case.
For the show the game will consist of allowing attendees to join the game by allowing them to get numbers. They will then be able to play as they walk the show floor, looking for players among the rest of the crowd.
