Assassin’s Creed Odyssey has many trophies and achievements you can unlock. To achieve 100% progress, you have to solve or unlock all these tasks.
In this guide we show you the following trophy / achievement:
Recover the Cyclops’s eye from a goat on Kephallonia.
You must have played Sequence 1 of the story to be able to do this task. At the end of the Sequence you meet a boss named "Cyclops". There is a cutscene in which the Eye of the Cyclops is put into the rectum of a goat. Later you can find that eye again. Just return to Sequence 1 and kill some goats somewhere on Kephallonia. After 10-20 goat kills it will drop.
