What is Monster Mystery?

A free-to-play, third-person survival game for three to ten players, set at night. Explorers gather supplies and repair generators to reveal the Hidden, then kill them to win; the Hidden shifts into monster form to kill every Explorer. Lanterns need refueling at fireplaces, which require boards to stay lit.
