Splatoon 3: Expansion Pass: Wave 2: Side Order teaser trailer
A teaser trailer revealing Side Order was shown in the latter half of the trailer shown in the February 2023 Nintendo Direct. The teaser trailer opens with a slow pan across a dull, stark white version of Inkopolis Square from, slowly focusing on Agent 8, who is wearing new gear. This altered version of Inkopolis Square features presumed dead or bleached coral; Deca Tower has been replaced with the Spire of Order. A swarm of fish-like objects "swim" around Agent 8 towards the end of the clip shown.

Throughout the trailer, various cryptic static images and short video clips briefly flicker on-screen; the images primarily depict Agent 8 in strange bright white locations, as well as Off the Hook, while the clips seemingly depict biological components such as cells, blood, and organs.

A dull, slightly out-of-tune music box melody with steady electronic percussion accompanies the teaser trailer, which slowly grows more intense; towards the end, someone can be heard speaking.

Side Order trailer
A second Side Order trailer which focused on gameplay was shown in the September 2023 Nintendo Direct. The trailer opens with Agent 8 in an updated version of the dull, stark white version of Inkopolis Square alongside the Pearl Drone, a drone resembling Pearl, as the same out-of-tune music box melody featured in the first trailer plays.

Agent 8 is shown descending into an unknown Floor via a grappling attachment on the Pearl Drone. The Pearl drone, Agent 8's equipment and a new type of unknown fish-like enemy are revealed, then gameplay footage of Agent 8 in combat with the enemies is shown. The new enemies appear to spawn en masse from a black orb-shaped mechanism.

Cutscene footage of Agent 8 and Pearl encountering Acht in an elevator is then shown; within it, Acht introduces themself as an old friend of Marina's. The Floor Selection and Palette screens are shown, then Agent 8 enters the Exposed Winding Floor. Gameplay footage of several different unknown Floors is shown in quick succession, then the trailer abruptly cuts to a clip of Agent 8's octopus ghost entering a crystalized shell resembling their form, seemingly spawning into a Floor. After a cut to black, Agent 8 is shown running in slow motion alongside the Pearl Drone towards a very large six-tiered mechanical contraption; each of its tiers has separate types of protruding components and spins independently of the others. After another cut to black, the mode's title is shown with glitch and black coral effects.

Throughout the trailer various scenes depict the Spire of Order's Floors seemingly spontaneously generating with a Matrix-style code effect. Many Floors shown appear to have blocky, black holes in their walls reminiscent of a greeble effect. Additionally, Armor pickups and an unknown can-shaped pickup bearing Marina's poster design can be spotted within certain Floors.

Agent 8's ink color is significantly paler compared to the previous trailer; their ink color tint appears to change between clips, seemingly being affected by different color chips. Their gear appears at various stage of upgrade throughout the trailer; the seemingly well-upgraded version includes thin, bright, hologram-like extensions on their Dualies, as well as an eyepiece similar to the See-an-Enemy HUD.

The trailer opens with the same musical box tune heard in the teaser trailer, then cuts to a slow-paced electronic glitch song with prominent industrial percussion. Midway, the song swaps for a more intense electronic song, then at the end into a different slow, echoed song.

Story
The mode takes place in "what has become of" Inkopolis Square, the main hub of, in "what would've happened" if Team Order had beaten Team Chaos.

Agent 8 has been unexpectedly transported to the Order Sector, a mysterious world that is build out of its own unique rules. Agent 8 wakes up to find what appears to be Inkopolis Square, suddenly drained of color and uninhabited. They are challenged to ascend the Spire of Order, a tower that changes floor structure each time it's entered, which has mysteriously replaced Deca Tower. Pearl, having been transformed into a drone called the Pearl Drone, accompanies Agent 8 and assists them in combat.

The mode's missions take place in the Spire of Order's many different Floors, where an unknown species of creatures that resemble robotic fish serve as enemies. Clearing Floors rewards the player with enhanced abilities and tokens of an unknown purpose.

Acht, also known as Dedf1sh, has "wandered into" the Order Sector, and appears to travel between Floors alongside Agent 8 inside an elevator within the Spire of Order.
