Turf War (Octo Expansion)

Turf War is the final boss of the Octo Expansion.

Gameplay
The player has 3 minutes to shoot the Hyperbombs Marina drops onto the NILS Statue and stop Commander Tartar from destroying Inkopolis.

The map of the stage is displayed on the screen during the batlle as opposed to being viewed when pressing, and rotates around depending on where the player is compared to the usual maps that have a fixed view.

Trivia

 * The start of the final boss battle displays a screen similar to the start of a multiplayer match (complete with a minor-key version of the Splatfest match start theme), with Turf War being the mode, "Defend Inkopolis from ultimate doom!" being the objective and the NILS Statue being the stage.
 * If the player fails to activate all the bombs before the time runs out or falls into the water, the game continues off to show the aftermath where the NILS Statue destroys Inkopolis with characters reacting to it. The image of Inkopolis getting covered by the goo in from the laser is viewed from the same angle as the start-up screen.
 * This is the first time in the Splatoon series, where the consequences of the player failing a final boss are shown.
 * When Pearl fires off the Killer Wail to counter the laser from Commander Tartar, a screen displaying the turf percentages pops up, identical to the prompt that appears at the end of a Turf War, where Pearl wins by 888.8%.
