The game is set in a dark fantasy world and has three factions to which you can pledge loyalty and undying devotion. The devs describe War of Omens a hybrid between deck-building games like Dominion and traditional collectible card games like Magic: The Gathering. Players will purchase cards during play that will then be shuffled into their inventory for future rotation. There are also resources to collect and use during the course of a match.
Fifth Column is asking for $30,000 in funding to finish the title. As added incentive to donate, all those who chip in $10 or more will be given an early access beta key. You can get a look at how a battle works after the break.
