A dark evil stirs beneath the once peaceful land of Tasos… Deep within the four Great Dungeons, the ancient seals that hold the Titans at bay are gravely weakened and their minions have unleashed terror upon the world.

The Goddesses who forged the seals long ago have made a desperate plea for a band of heroes to come forth and save the people from a terrible fate…

You are one of the heroes tasked with saving the realm of Tasos from the terrifying Titans. Whether you choose to take on your mission solo, or with up to three friends is your decision to make. Do you have what it takes to save Tasos?
