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 hyperbombs are added to different locations on statue and first appear after a certain amount of time has passed. These are as follows:


 * At 3:00 five hyperbombs in light blue color will drop at the chest area of the statue.
 * At 2:30 five hyperbombs in a green color will drop at the neck.
 * At 2:00 five hyperbombs in a yellow color will drop at the back.
 * At 1:30 five hyperbombs in a pink color will drop at the right arm.
 * At 1:00 ten hyperbombs in a dark blue color will drop at the head.

Due to the statue's sheer size, 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. Hyperbomb locations will be marked on the map as they are dropped and can be seen through walls, and a tally of the hyperbombs that have been activated will be listed so the player can keep track of how many are left.

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.
 * The "Skip" option becomes instantly available if the player fails the final boss.
 * After detonating the last hyperbomb, additional comments from the supporting characters will roll out up to 5 seconds remaining, after which no new lines will be displayed.
 * To view the entire fluff text ending with Cap'n Cuttlefish's comment, players need to hit all bombs with approximately 32 seconds left.
 * 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%, resulting in the meter that shows the percentages breaking, similar to a Ranked Battle meter.
 * The meter cracks and breaks in sync with the music.
 * During Pearl's Killer Wail, Octoballs can be seen flying out of the NILS statue despite the fact they are not seen anywhere in Splatoon 2.
 * The mission's objective text that is displayed after the battle begins, being "Ink to save the world!", is only displayed in the first attempt of fighting the boss and is not shown again when choosing to retry it after failing. This is the case for subsequent replays of the escape sequence post-game as well.
