Assassin's Creed Odyssey is out now on all platforms, and it's the series' largest game to date. The overall map in Odyssey is over twice the size of the one in Assassin's Creed Origins, and it's filled with a branching main storyline and hundreds of side quests. Simply playing through the game's campaign only scratches the surface of how much you can do.

For our Assassin's Creed Odyssey review, editor Alessandro Fillari completed the game's main story in just over 50 hours. And that's without hitting every single island and side mission available. There's a broad array of optional content to tackle outside the main campaign, including additional islands to explore and mythological creatures to slay.

Assassin's Creed Odyssey also has nine different endings. Not every ending is dependent solely on late-game decisions either, so you won't be able to save near the story's end to quickly see what you missed. For some of the endings, you'll need to make key choices early on--even as early as the game's opening two hours--and then make dialogue decisions or take certain actions throughout the campaign. You'll have to play through the entire game numerous times just to see everything, so if you're looking to see all the game has to offer, Assassin's Creed Odyssey will probably take you hundreds of hours to fully complete. That's not counting the two episodic post-launch expansions--Legacy of the First Blade and The Fate of Atlantis--that continue Kassandra and Alexios' story.

In our review, Alessandro gave Odyssey an 8/10, and described the game's ambition as "admirable" while also complimenting "its rich attention to detail" and "multi-faceted narrative with strong protagonists at the lead." Unfortunately, its massive campaign was occasionally "tiresome" so going for all nine of Odyssey's endings will be a daunting, time-consuming task. With no Assassin's Creed game scheduled for 2019, it's clear Ubisoft wants you to be playing Odyssey for a very long time.

Assassin's Creed Odyssey launched today, October 5, for Xbox One, PS4, and PC.
