Undeniable Flying Object

Undeniable Flying Object is the fifteenth mission in single-player mode, Octo Valley. It takes place in a modified version of multiplayer stage Bluefin Depot.

Walkthrough
Captain Cuttlefish will point out that there is an Octostriker at the Depot. The player will see that there is ink to hide in so the Octostriker will not see them. If the Octostriker does see them, the ink will most likely save them. All of the Octobombers will make this even more challenging for Agent 3. At the path where it splits, there will be two Octobombers waiting for Agent 3 on both sides. The last two Octobombers will attack, trying to defend the Octostriker at the end before the fight.The armor will help the Inkling in the boss fight, making them have "more lives". All of the Octocopters respawn at the end, making the main enemy the Octostriker.

Trivia

 * At the end of, after the Octostriker has been defeated and the music stops, some unusual sounds can be heard: an erratic clanking and a faint moan, which are slightly louder towards the edge of the UFO. These sounds are also heard when using Recon to explore Bluefin Depot during a Splatfest. Given Callie's comments on the stage, they may be the result of paranormal happenings or simply the deterioration of old structures.
 * The Italian name for this stage, like all UFO-related stages, references a science fiction movie - in this case, Close Encounters of the Third Kind.
