Titan Souls is a open world, 2D, top-down action-adventure, where the player has only one arrow and can only take one hit. The goal is to defeat the nineteen giant monsters called the Titans, which can, just like the player, only take one hit but only have one way to be defeated. During the fight, the player has to figure out how the respective boss behaves and by that find a way to defeat that boss. (wikipedia.org).
