Although you'll fight another Cyclops right near the beginning of the game in Assassin's Creed Odyssey, that Kephallonia mercenary isn't quite of the mythical persuasion as this giant beast. In order to even start your journey towards beating the Assassin's Creed Odyssey Cyclops, you'll need to be at least level 35, as you'll be heading to the island of Kythera in order to find the quest. It's one of the hardest to start though, as the questline doesn't mention Cyclops - or eyes for that matter - at all.

How to find the Assassin's Creed Odyssey Cyclops
You'll pick up the mission at the Pilgrimage Site in the region of Pilgrim Hill on Kythera Island. It's called A God Among Men. There's a man preaching near a statue covered by a little canvas gazebo near the edge of the cliffs. There's a man there moaning that his "god" has been taken prisoner at the nearby fort, and it basically seems like they worship him because he has an - ahem - gift between his legs.
You'll need to find and free the god - aka Empedokles - and escort him back to his worshippers. Don't worry though, he's got underwear on to hide his gift from our mere mortal eyes. It's only in front of his personal statue that he'll give you the full spiel though, so prepare yourself for a man who actually believes he's a god and wants to introduce you to his celestial family. But first, he'll need to go fetch him a disk - which will eventually be the key to opening the door to the Cyclops.
Thankfully, the key was stolen by the same man who took Empedokles' clothes, and happens to be strolling nearby. Kill him and his guards to get the key before returning to Empedokles.
Now you'll have to go and meet his godly family, which actually reside on an island in the Gulf of Korinth, to the south of Phokis, in a location known as the Cave of the Forgotten Isle on the Island of Thisvi. Head over there, and go through the cave, swim through the water and emerge to find Empedokles standing by a half-broken door, talk to him and prepare yourself to meet his family.
How to beat the Cyclops
Unfortunately for Empedokles, his family turn out to be none other than the Cyclops himself and opening that door gets him killed and serves you a fight with a giant.
Thankfully, dealing with the Cyclops and taking him down is none other than a game of patience and precision arrow shots. As you've probably learned with games now, the glow's the goal, and his glowing eye makes for a serious weakpoint. Hit him enough and he'll go down, allowing you to get in some melee slashes with your swords and other weapons or abilities, meaning all you need to do is keep doing that until he's down.
When his health goes down to half though, he will throw a bit of a tantrum, grab himself a makeshift stone club and try to turn you into a pancake. However, if you just keep up with the same combat tactics, he'll be down in no time. Just watch out for falling rocks.
For defeating the Cyclops you get an engraving that lets you deal 25% more damage on elite and boss enemies, and the Legendary Heavy Bladed Polyphemos Cyclops Bludgeon, which actually has the same perk as the engraving. Watch out elites and bosses.
