This Downloadable Content (DLC) for Splatoon 3, released in 2023, expands the game by adding Inkopolis Plaza as an alternate, accessible hub world, requiring the base game to play. Gameplay focuses on accessing existing services like shops and the Tableturf Battle Dojo within this nostalgic setting. Its distinctive feature is hosting unique live concerts by the Squid Sisters during Splatfests, offering atmospheric variety rather than new core shooter mechanics.
This DLC introduces Inkopolis Plaza as a new, accessible hub world. Players can travel to this location via the subway station found in the main game's hub, Splatsville. This offers a distinct atmospheric alternative to the primary city environment.
While the location is new to the current game iteration, it mirrors the layout and services of the original setting. Players gain access to classic storefronts such as Ammo Knights, Cooler Heads, Jelly Fresh, and Shrimp Kicks. It is important to note that the merchandise lineup available at these shops reflects the current inventory found in Splatsville, ensuring continuity with the base game's progression system.
The primary enhancement comes through atmosphere and live events. The Squid Sisters, Callie and Marie, perform concerts within Inkopolis Plaza during the game's recurring Splatfest events. During the first half of these events, they perform "City of Color (2023)," and during the second half, they perform "Tomorrow's Nostalgia Today," both while wearing their original attire from the first installment of the series.
Furthermore, the hub incorporates several elements from the base game into the new setting. The Great Zapfish can be observed atop Inkopolis Tower, and the functionality of the amiibo box remains accessible. Elements like the Grizzco Industries building and a hidden Tableturf Battle Dojo are also integrated into the plaza's layout, accessible behind certain structures.
As a DLC, this content requires the base game to access and utilize its features. It primarily focuses on expanding the social hub and providing cosmetic/atmospheric variety rather than introducing entirely new gameplay mechanics or a separate story campaign. The core shooter and platforming mechanics remain those established in the parent game. This addition serves to enhance the player's daily routine within the game by offering a nostalgic, alternate location for accessing existing services and enjoying unique live performances during special events.
No entirely new core gameplay mechanics are introduced with this specific DLC wave. The focus is on integration and presentation. For instance, the entrance to Octo Valley is blocked off, and the arcade machine is replaced with a terminal that allows remote access to Hotlantis, ensuring that the functionality of the main hub is mirrored or accessible from the new location without altering the fundamental systems of the shooter or battle modes.
