Three horrific harbingers herald the crises to come. As a powerful seer, use your mystic visions to prepare against the ever-worsening perils.

Harbingers builds on the existing Mysticana solo game Nine Perils with new Harbingers, special abilities, escalating challenges across three rounds, and a cooperative mode for 2 players.

Harbingers is an expansion to the Mysticana deck that can be played solo or in a 2-players co-op mode. It is based on the gameplay of Nine Perils and introduces 6 double-sided cards with Harbingers on the front and Visions on the back. Each game uses 3 Harbingers and 3 Visions: Harbingers are placed above the timeline and introduce additional restrictions to some perils, while Visions provide one-time effects that help the player. The game is played over 3 rounds, with an increasing number of Harbingers in play each round. Win all 3 rounds to win the game. In the cooperative mode, players strategize together without revealing their cards and, each turn, choose one player to play.

Mysticana is a Foundation Deck: an 18-card deck that includes multiple core games using just the base cards with even more games added through small expansions. The deck features cards with 6 ranks across 3 suits (elements) which have a rock-paper-scissors hierarchy. While each game might make use of the decks design in different ways, the flexible foundation enables new games to fit in seamlessly alongside previous entries.
