KYIV, Ukraine — "Quest" is a massive scavenger hunt that blends urban exploration with online cooperation and logic puzzles. Typically, players search vast areas for hidden codes that they then input into their smartphones. Finding a sufficient percentage of the codes hidden in each "level" unlocks the next location, sending the teams scrambling back to their cars. All-night season-finale games, like the ones shown here, begin in the early evening and finish the next morning, often traversing hundreds of kilometers in the process.
A player searches an abandoned missile silo for hidden codes while "Chumbawumba" thunders from a speaker and a purple strobe light provides illumination during the final stage of a game titled “10 Years of Cereberal Coitus” (10 лет церебрального коитуса) in the early morning hours of September 6, 2015, in Zhitomyr Oblast, Ukraine. The partially-flooded silo contained R-12 (SS-4) ballistic missiles during the Cold War. The game was organized to celebrate the 10-year anniversary of the organizing team, Peugeot Pride.
