The fate of the world is in your hands... In Shards of Infinity: Shadow of Salvation, the third installment of the award-winning deck-building game, players can choose one of two modes to play! Play a classic game of Shards using the hero Rez's new Relics and Allies to take down your opponents in player vs. player battles OR heed the warning of the time-traveling Rez and play co-operatively in a new campaign mode to battle through a series of bosses with up to four of your friends! In co-operative mode, you read from the innovative "Battle Book", which tells a branching story. As the time-traveling Rez, you must decide which threat to take on with your team. Every choice has a consequence, as does your success or failure against these growing threats.
