Nintendo announces that Splatoween returns in Splatoon 3, starting on 31 October. The Halloween-themed event lets players join one of three teams—Wizard, Knight, or Ninja—and earn participation and event-related progress through match play.
Multiple outlets describe the event as another yearly Splatfest-style celebration. Nintendo Life frames it as a recurring “spooky showdown” with the theme “What would you be in a fantasy world?” Players choose sides in advance for the event weekend, which runs around 31 October.
The outlets also emphasize that the teams face off during the event through Splatoween-specific competitive modes. My Nintendo News highlights that Tricolor Turf War matches feature the three-team selection, with each faction presented amid Halloween decorations. While both sources agree on the dates and team options, they differ slightly in wording and emphasis—one focuses on the selectable teams and Tricolor Turf War, while the other highlights the overarching fantasy theme.
