Orestes must fulfil his destiny by trial in the Labyrinth beneath the palace and find the solution to the puzzle, or perish in the attempt.

The inter-connecting chambers were created by the gods to punish errant mortals and hidden in 16 special rooms are objects known as Euclidian shapes, geometric designs based on triangles, circles and squares; six of which, when positioned correctly in the Guardian's chamber reveal the exit and success. This chamber however is home of the Demi-Gods who use their power of illusion to prevent discovery of the shapes-Orestes must be wary of this deceit! To assist our Hero in his search the Gods have revealed the solution to Electra imprisoned beneath the palace, "Find Electra", Orestes is told, "She will lead you to the shapes you need", but without the help of Electra, Orestes must determine which shapes from which rooms must be taken to the Guardian's chamber.

Terrifying illusionary creatures by the Demi-Gods will try to sap Orestes' strength.. .he is advised by Zeus "Whenever you feel weak go at once to the Guardian's chamber where your strength will be restored" — If the creatures can be killed their power will temporarily be lost. "Use this fact to your advantage" advises Apollo.

Finally Orestes is warned that Clytaemnestra has learned of his task from a soothsayer. She has entered the catacombs to kill Electra, making Orestes task all the more difficult since he must protect his sister-without her he may never solve the puzzle!

Orestes enters the darkness from where no human has ever returned. . .
