Nintendo Europe released the official 2026 Halloween illustration for the Splatoon series on October 30, sending holiday greetings to the Inkling and Octoling characters. The company also recommended weekend gameplay content for Splatoon: Side Order and Splatoon 3. The illustration continues the series' traditional holiday campaign style, showcasing Inkling and Octoling characters in Halloween costumes.
During the event, players can take on hordes of Salmonids in Splatoon: Side Order or join the Splatoween festivities in Splatoon 3. The currently announced details do not include specific times, rules, teams, or rewards for the celebration. Splatoween is an annual Halloween tradition in Splatoon 3, typically featuring themed team battles and limited-time decorations.
Splatoon 3 has previously released the "Order" expansion content and the major version 11.0.0 update. However, this announcement primarily focuses on the Halloween festival illustration and does not reveal any new version updates, additional characters, paid content, or standalone rewards.
