Splatoon 3 may be a multiplayer game first and foremost, but the single-player mode, Return of the Mammalians, is another exceptional step forward for the series. As we explain in our Splatoon 3 review, the single-player levels in this game are truly thrilling, and it’s definitely worth diving in if you’re even slightly interested.

Taking a break from the multiplayer doesn’t just offer you some fun puzzle gauntlets, however, as you can also learn more about the world through Splatoon 3’s Alterna Logs. These are text-based lore dumps, explaining the history of the world, how it ended up as it is in-game, and how Alterna came to be.

But how do you unlock Alterna Logs? Well, that’s what we’re here to help you with. We also recount a brief history of Splatoon’s strange world, so if you want to avoid spoilers, don’t read too far down! Anyway, for more exciting Splat content, check out our Splatoon 3 codes, Splatoon 3 app, and Splatoon 3 Salmon Run guides.

What are Splatoon 3 Alterna Logs?

Alterna Logs are scraps of information slowly revealed to you as you progress through Return of the Mammalians, Splatoon 3’s single-player mode. The text is scrambled until you start completing levels.

How do you unlock Splatoon 3 Alterna Logs?

To unlock Alterna Logs, you need to complete the levels in Alterna. There are seven different logs, numbered one to six, with the seventh known as Log.exe. To unlock all of them, you need to do every single level in the single-player mode.

Of course, you don’t need to complete all the levels to get to the end of the game, but if you’re a true lore hound, be sure to clean up that muck and dive down those grates to take on every last challenge.

What do the Splatoon 3 Alterna Logs say?

All the logs recount the end of the human race as we know it and the development of these strange new creatures. You can read them in full below.
