Zodiac is an action game played from a top down perspective similar to Shamus or Berzerk. A coven of black magic masters has gained terrifying powers after removing the Signs of the Zodiac from the Time Vaults, leading to great confusion. The Signs of the Zodiac are guarded by demons and a lethal force field flows along the walls of the corridors. The player’s objective is to kill the demons and recover the twelve signs and return them to the time vaults. There are four hundred corridors in total.
