Version 4.0.0 (Splatoon 2)

Version 4.0.0 is an update to Splatoon 2 that was released on 2018-09-14 at July 27, 2024.

Splatfest
Two new modes for Splatfest battles, Normal and Pro, replaced the previous Solo and Team modes.

Splatfest Battle (Normal)
Normal mode can be played solo or as a team of up to 4 friends. Playing with fewer than four friends will add the appropriate number of other players to the team. Selecting "Continue" or "Change gear and continue!" allows players to continue onto the next battle with the same team.

Points for turf inked by individual players are added to the points earned by the team for winning a battle, resulting in a value known as "clout," and the side with the most clout at the end of a Splatfest is the winner. Clout is not added for battles between the same side.

If a team is on a winning streak, the game will try to match them against other teams on a winning streak. When there are multiple teams with the same number of consecutive wins, teams will be matched with a team as close to their skill level as possible.

When weapons, gear, or general styles of four players in a team meet certain conditions, a nickname and a synergy bonus will be given to the team. A synergy bonus can reward more Splatfest points or clout for victories.

Splatfest Battle (Pro)
Pro mode is similar to the previously available Solo mode. Players battle solo, increase their Splatfest Power by winning, and are matched against other players with a similar Splatfest Power. A Splatfest Top 100 list continues to be made available on SplatNet 2, ranking players with the highest Splatfest Power.

Players receive clout equal to the opposing team's approximate Splatfest Power. The side with the most clout when the Splatfest concludes wins. Clout is not added for battles between the same side.

Other changes
The final Splatfest results are decided based on three factors: votes, clout from Normal mode players, and clout from Pro mode players.

10x Battles and 100x Battles will now occur randomly, earning players on the winning team a boost of clout for their side. They occur for both Normal and Pro divisions. When a friend wins a 10x Battle, or if anyone wins a 100x Battle, that information will be displayed on the Lobby screen or the signboard in Inkopolis Square. The amount of Splatfest Power does not increase in these battles.

Continuing to earn experience even after a Splatfest Tee is at max level will earn players a random ability chunk each time they pass a certain point threshold.

Weapons
The first Kensa Collection, a line of weapons designed by Toni Kensa, was released with the update. The weapons became available an hour after the update. It includes the, , , and.

Music
One new track was added to be played during Salmon Run battles: Frantic Aspic by ω-3. The track plays when players use a certain combination of supplied weapons during a regular enemy wave.

Trivia

 * In one of the promotional pictures for the Kensa Splat Dualies, an Octoling boy is seen with no shoes on their feet. This lead some players to believe that an option for the players to be barefoot would become available in Version 4.0, but so far, nothing has been announced or added.
 * It probably is because there are only three shoes produced by Toni Kensa, all of which are worn in the other three promotional pictures. Toni Kensa ads seen on Starfish Mainstage feature barefoot Inklings, so it may not be anything big.
