From the publisher's website:

Mythic Battles Mythic Battles is a strategy game in which breathtaking battles and epic confrontations take place. Thanks to its innovative game system, the Building Board Battle (BBB), which combines principles from miniature games, board games and card games, Mythic Battles will offer you an experience the likes of which you've never had. Before facing your opponents, choose your faction (Athena or Hades - with more factions to be released later) then recruit between 5 and 10 Units. Each of your Units is represented by a stack of cards indicating its combat abilities as well as a token which gives its position on the battlefield. During the confrontation the characteristics of the Units will change depending on the damage they've suffered, until the final blow has been dealt to them. You'll also have a deck of cards to draw from to lead your Units. It'll be up to you to lead them as best you can in order to get the upper hand against your opponent. To win the game, you'll have to be the first to reduce the enemy army down to 3 Units.
