Splatoon is most well-known for its colorful multiplayer modes and gameplay, but it is a series that has always included a single player campaign as well. If you want to, you can play through the entire story whenever you don’t feel like going against real players in multiplayer. How long does the Splatoon 3 Hero Mode campaign last, though? Here is a list of all the campaign levels in Splatoon 3.

How long does Splatoon 3’s Return of the Mammalians single player take to beat?

In general, Splatoon 3: Return of the Mammalians should take you somewhere between five and six hours to beat. It is not a particularly long campaign to beat and the game allows you to skip levels with the right number of Power Eggs. If you are rushing and skipping through the game, you could potentially finish it closer to the four-hour mark.
