Nintendo announced Splatoon Raiders in 2025. The reveal took place on June 10, 2025, when Nintendo introduced the spin-off for Nintendo Switch 2.
The announcement was notable because Raiders was presented as the first Splatoon spin-off. Instead of continuing directly with a numbered sequel, Nintendo shifted the focus to a new mechanic protagonist, the Deep Cut trio and the unexplored Spirhalite Islands.
The year can be confused with 2026 because the game’s release schedule belongs to a later period. Announcement year and release year are separate facts: a game may be revealed well before it launches. Likewise, Splatoon 3 was released in 2022, but that earlier date does not apply to Raiders.
The June 2025 reveal also included information about a Splatoon 3 update for Switch 2. That shared presentation context helps explain why some summaries mention both games, but it does not change Raiders’ announcement year.
