The Splatoon 3 event announced as a Raiders promotional tie-in was a Splatfest.
Nintendo announced a special Splatoon Raiders-themed Splatfest for Splatoon 3 as part of the game’s marketing campaign. The event was scheduled for July 10–12, 2026, shortly before Raiders launched for Nintendo Switch 2 on July 23.
Splatfests are competitive, limited-time events in which players choose among themed teams and compete in Turf War matches. They are a defining social feature of Splatoon, so using one to promote a new spin-off connects Raiders to the established multiplayer community.
The other choices describe different Splatoon features or activities. SplatNet is Nintendo’s companion service and app ecosystem, while Big Run is a special Salmon Run event. Eggstra Work is also a Salmon Run-related challenge, not the name of the Raiders collaboration. The promotion was therefore specifically a Splatfest, not a new mode or online service.
