8 June 2019
The final Splatfest has been announced — Chaos vs. Order! It will be held in all regions for 72 hours from 18 July 2019 to 21 July 2019. Four new headgear items based on this Splatfest theme will be available. The Nintendo Switch News Channel will be updated in late June with instructions on obtaining the gear. All 23 previous Shifty Station layouts will appear, and a new Shifty Station layout will premiere in the last 24 hours of the Splatfest!
In addition, version 5.0.0 will be released after the Splatfest. This update will add a "Turf War (Splatfest)" option to Private Battles, allowing players to experience all Shifty Station layouts as well as the Splatfest (night-time) versions of each normal stage!
