Exposure

Exposure - A Radiating Card Game is a fresh take on the social deduction game genre popularized by Mafia/Werewolf.
In Exposure, you are handed a hidden role where you strive to quarantine the Uncontrolled Radiation - or to see your victims succumb to radiation poisoning.
The game plays over several rounds, with each round consisting of an Exposure phase, a Survey phase, a Quarantining phase, and a Reposition phase.
Exposure features two game modes, play either a classic Versus variant, or a Co-op mode where all players work together to quarantine the Uncontrolled Radiation.
