Tactical combat game, where you choose one or two characters, who fight each other (it's also possible with a multi-player variant, where some players can cooperate to win). The winner is the one who succeeds in getting the opponents "Condition Points" down to zero.
The combat rules are unusual, well thought-out and interesting. Instead of throwing a die, you choose a number 1-6 (depending of the attack type, the range might be lower) on the die and the defense is a certain number of guesses to find out what the opponent attacks with. Number of attacks depends on the active combat card (defense cards gives more guesses, but lower attack damage). The higher value, the higher becomes the damage, but if you always chooses the highest value, it's soon penetrated!
You play the game by choosing the cards and their order from your characters card deck and you have to out-guess your opponent.
