Soul Hunters is a card game, where you are tasked into collecting souls with the use of the title characters (soul hunters), which are divided into six different alignments (factions). By focusing on a single alignment, you receive a bonus on your influence, which is used to lure souls. You can collect negative or positive influence, depending on which characters you use, with either "side of the coin" being equally powerful but in a different ways.
The game mechanics makes it really easy to learn, since the cards pretty much explain themselves, but it also gives you a chance to use tactics and cunning to win.
