The release date announcement was accompanied by a new trailer for the game, which is viewable below.
It features over three minutes of footage of Splatoon 3’s online 4-v-4 Turf War battles.

The online mode will include a mix of new and returning stages, where teams are challenged to cover the most ground in their ink.
The latest footage features a new stage, Eeltail Alley, and a new weapon called the Stringer, which is a bow that shoots ink sideways and vertically.
In addition to Turf War, Splatoon 3 includes a new single-player campaign and a fresh version of the Salmon Run mode.
Nintendo said in February that Splatoon 3 would be released this summer.
The game is now available to pre-order at selected retailers with a suggested retail price of $59.99 / £49.99.
Nintendo released Splatoon 2‘s final significant update, version 5.0, in July 2019 after two years of post-launch support.
Earlier this week, Nintendo brought forward the Xenoblade Chronicles 3 release date to July.
Monolith Soft’s RPG was previously scheduled to arrive in September, a slot which will now be filled by Splatoon 3.
