Through its cell-phone-guided scavenger hunts, MetroDemic injects 90-minute thriller-scenario into downtown areas. Groups of up to four players can step into the role of heroes anytime via their cell phones, striving to save the city from a deadly outbreak. After the mission begins, players must navigate “outbreak” sites around local sites. As they solve puzzles, find clues, and correctly answer trivia questions, they'll save more and more lives.
