Graywalkers: Purgatory is a turn-based strategy with role-playing elements in a post-apocalyptic setting, where Heaven and Hell are intertwined with Earth as a result of a global Rupture. You play as the prophesied leader of the 36 righteous, now called the gray walkers. You and the other Greywalkers walk a path between heaven and hell, darkness and light, each charged with protecting humanity in their own way. Your goal — Find 35 other gray walkers and recruit them to unite Purgatory and lead the fight to free the world from the supernatural invaders that have taken over the rest of the world.
