Chaos vs. Order

Chaos vs. Order, also known as Final Fest: Splatocalypse, is an ongoing Splatfest event in Splatoon 2. It is being held in all regions for 72 hours from 2019-07-18 to 2019-07-21, and for the first time, all regions begin and end this Splatfest at the same time. It was announced at the Splatoon 2 World Championship 2019 and on social media on 2019-06-08. It was announced in-game on 2019-06-26.

Details
This Splatfest is the final Splatfest held in Splatoon 2. In this Splatfest, a new Shifty Station layout will be introduced, alongside the return of every Shifty Station layout introduced prior. For the first 48 hours, all previous layouts are part of the Splatfest Battle rotation. For the last 24 hours, the new layout will be playable. Also, the chance to encounter a 100x Battle is 100x more likely for this Splatfest.

Four pieces of headgear (two for each team) are now available in a Squid Research Lab Report article on the Nintendo Switch News applet.

A trailer revealed the alignment of characters and weapons, detailed in the table below.

Shifty Station's outcome
Although this is the final Splatfest, Nintendo announced that the Version update for Splatoon 2, which will go live after this Splatfest ends, will introduce Splatfest Battles on Private Battle mode. Every Shifty Station layout, including MC.Princess Diaries, will be available in this mode and the host will be able to choose the team ink colors from a list of all 51 Splatfest color schemes from every region. Every stage, including the regular stages available in the base game, will have a day and night mode.

Music
This Splatfest contained unique battle music tracks that did not play in any other Splatfest. Ink Me Up returned from for the first time, with the Squid Sisters' version of Now or Never! playing if it is chosen, while Shark Bytes makes its debut as a battle theme and there is a unique version of Now or Never! based on Off the Hook's version, but also starring the Squid Sisters.

Trivia

 * In the promotional art, Callie is shown wearing Pearl's crown from the Octo Expansion while Marie wears Marina's headphones.
 * It is widely suspected that the outcome of Chaos vs. Order will affect the plot of a sequel game, similarly to Callie vs. Marie.
 * Every character in the game who leads a major role appears to have chosen a team, including the antagonists (the Octarians, DJ Octavio, the Salmonids and the Telephone).
 * The Telephone is of particular note, as although he was destroyed in the Octo Expansion, he is shown still in one piece in the promotional art.
 * In the announcement dialogue, Pearl mentions Agent 8 and Captain Cuttlefish, making this the only Splatfest to have been confirmed to take place after the Octo Expansion.
 * When the Splatfest was announced in-game, Pearl invoked Article 4 of Splatfest Law, in which the outcome of the Splatfest must take effect in Inkopolis, hinting at a major change in the future.
 * A similar rule stating that what the winning side prefers is now legally better than what the losing team wants has also been referenced during previous Splatfest dialogue, including Cake vs. Ice Cream, Film vs. Book, Chicken vs. Egg, and Front Roll vs. Back Roll (indirectly). However, it has never been referred to as Article 4; all other references have been to "Chapter 3" instead, implying that Article 4 may be a separate part of Splatfest Law altogether.
 * A few lines through the announcement dialogue, the normal background music is temporarily replaced by The Plan.
 * Both Pearl and Marina’s new outfits’ colour schemes are similar to that of their Trick vs. Treat ones, with Pearl’s being mainly black and Marina’s being mainly white/silver.
 * In the days leading up to Splatfest, gold and silver stickers started to show up and quickly spread around the square. All these stickers featured images drawn by the community.
 * Interestingly, an image drawn for Team Order can appear on a Team Chaos and Team Order sticker, and vice versa.

Dialogue
'''Note: The Results dialogue currently provided for all languages appears to be very bare-bones, possibly placeholder text. This is noticeable in Europe's versions, and would seem to indicate Nintendo is aware of data miners collecting the results dialogue before the Splatfests, and will most likely update the Splatfest files after the Splatfest concludes.'''
