What remote islands are explored in Splatoon Raiders?

The remote islands explored in Splatoon Raiders are the Spirhalite Islands.

The archipelago is a new setting for the Splatoon series, separate from familiar locations such as Inkopolis, the Splatlands, and Octo Valley. The Mechanic and Deep Cut travel through these isolated islands while searching for treasure, salvage, and clues about the region’s history.

The islands give Raiders a different atmosphere from the urban hubs and battle arenas of the mainline games. Its environments include varied terrain and hazards, and the adventure is structured around entering island areas, gathering resources, defeating enemies, and returning with materials that can improve equipment.

Players sometimes confuse the Spirhalite Islands with Octo Valley because both are important single-player locations in Splatoon. Octo Valley is associated with Splatoon 1’s campaign, while the Spirhalite Islands are the distinctive new destination introduced for Raiders.
