Above The Earth is a superhero game designed around resource management mechanics. It’s flexible enough to handle street-level superheroes and cosmic powers, all in the same fight. "You have a hundred six sided dice; when you run out, you run out."
User Summary:
From a starting pool of one hundred six-sided dice, players spend dice to perform heroic actions and lose dice when they incur damage. Rolls are successful if the total of the dice rolled exceeds a target difficulty value. Any dice that roll a 1 are returned to the player's pool.
