Hadean Tactics is a strategy game that combines the deckbuilder and autobattler genres, with roguelike elements. The player takes control of a hero with a unique deck and goes through the underworld using a procedurally-generated map that can be explored at will, with the amount of rooms visited amping the difficulty of the game.
During battles, the player can move their units and use cards to determine their actions in an automatic battle that can be paused at any time. Go against monsters, from the lowest of minions up to the mightiest of bosses, and defeat the lord of the underworld himself.
On each run, the player can encounter different cards, hire different units, and find different relics, all of which makes each run of Hadean Tactics a unique experience.
