Lots of genres are a bit over-saturated on the App Store, and card games are no exception. Combination card and fighting games, however, are few and far between. Aware of this deficiency, Hothead Games has seen fit to release Kard Combat this week. For the low low price of nothing.
Granted it's still more of a card game than a fighter; players choose from a handful of different mages with a few unique cards in their collection, matches involve planning and strategy as opposed to quick reflexes and so on. The fighting aspects have more to do with the brevity of each match and their one-on-one nature. It utilizes a slightly less complex version of the "line of cards" system some are no doubt familiar with, in which each user lines up their cards while any unopposed summons will do direct damage to the opposing player. Naturally, some cards have special effects that can create some interesting strategies.
Players can try out each of the four types of mages (Holy, Death, Machine and Dominator), as well as the Single Duel and multiplayer modes, for free. Full access to a single mage's campaign will require an in-app purchase of one dollar, while unlocking all four will cost three. And for any players interested in diving straight in to the multiplayer stuff, everything (all cards, etc...) can be unlocked for ten dollars. Bear in mind that the cards can eventually be unlocked through diligent play, and that the ten dollar purchase is only necessary for those who don't want to "waste time" with the singleplayer campaign.
