The Alterna Space Center is the final level in Splatoon 3's Hero Mode. It can only be accessed after beating all three Deep Cut boss battles (Frye in Cozy & Safe Factory, Shiver in Landfill Dreamland, and Big Man in Happiness Research Lab); once these requirements are met, the stage can be accessed by returning to the Squid Sisters Camp on Future Utopia Island and assembling the three treasure pieces together to create a giant power saw that the Captain uses to cut away all the Fuzzy Ooze that's blocking the way to the building.
Stages[]
Unlike the other six sectors of Alterna, the Alterna Space Center consists of just one very lengthy stage that is broken up into several smaller chunks. The first time the level is entered, the entire level must be beaten in one go; quitting the level means that the player has to start again from the beginning. However, if you revisit the level after having already beaten it or parts of it, you can skip certain sections using the Skip option found in the pause menu.
Each section in the Alterna Space Center takes place within a specific part of the facility, each one containing its own set of challenges to overcome. Between each stage is a short hazard-free, unskippable area where you can recuperate while making your way to the next section.

Trivia[]
- Whenever you reach a new section in the Alterna Space Center, a transitional screen appears showing a map of the whole facility, along with an arrow showing where you are. This is likely a reference to the Wily Castles in the Mega Man games, which feature similar transitional screens when moving on to a new stage.
