How do you find and beat the Cyclops in Assassin’s Creed Odyssey? This Mythical Beast is one of four creatures in the game, and must be defeated in order to access the finale of one of Odyssey’s major questlines. In order to begin your quest to defeat all of Assassin’s Creed Odyssey’s mythical beasts, you must first complete the main quest United Front, which is part of Story Sequence 7. Upon completing United Front you’ll unlock the side quest A Family’s Legacy. Head to the island of Thera and complete the light reflection puzzle to unlock the hidden city of Atlantis. After discovering Atlantis, you will unlock a new quest line: The Gates of Atlantis. To operate the gate, you will need to gather four different artifacts. Each artifact is in the possession of a mythical beast. In this instance, we’ll be retrieving the artifact from Kythera, which is held by the Cyclops. To begin your hunt for the one-eyed beast, head to Kythera Island and locate the A God Among Men sidequest, which can be found at the Pilgrimage Site on the island’s northwestern coastline. Here you’ll find a gaggle of NPCs arguing about a “god” who has been taken captive in a nearby fort. Accept the quest, and head just down the road to infiltrate the fort and rescue Empedokles.
