Octotrooper Hideout

Octotrooper Hideout is the first mission in single-player mode, Octo Valley.

Octo Valley
The player must speak to Cap'n Cuttlefish in Inkopolis to access Octo Valley. The kettle for this mission is to the left of Cap'n Cuttlefish along the path on the first corner.

Mechanics
Octotrooper Hideout is the first mission in Octovalley and introduces the player to several new mechanics that will be used throughout Octo Valley.
 * Launchpads are introduced as soon as the player enters the first mission and are used to navigate between the different checkpoints of the mission.
 * Vaultgreen introduced in this level and typically contain launchpads, but they can also contain mechanics such as inkrailgreen. Vaults need to be unlocked with keys, which are found in the nearby vicinity. In the mission Octotrooper Hideout, two vaults can be found. The first is located at Checkpoint 6 and is being guarded by an Octotrooper. The second vault is found at Checkpoint 6 and at first it appears to be unguarded, but as soon as you approach it with the key 2 Octotroopers and a Twintacle Octotrooper will appear.
 * Keygreen like vaults are introduced in this level and are used to unlock vaults. Most keys are either hidden or guarded by various Octarian enemies. 2 keys can be found within Octotrooper hideout. The first is located toward the back of Checkpoint 6 and the second key is located at the far right of the Final Checkpoint.

Beginning
First, hit the launchpad immediately in front.

You will face three Octotroopers: one on top of a box and two guarding behind. The brown boxes do not contain anything, but the reddish ones with a white label on contain Power Eggs.

After defeating the troopers, grab all the power eggs around. Power eggs can be obtained by walking close to them or shooting them.

There is a hidden power egg box behind the ramp.

Swim up the ramp by covering it with ink and transforming into squid form.

Checkpoint 1
The trooper in front has front-facing armour. In order to defeat it, you must shoot it it the back.
 * Swim around and shoot from behind, or
 * Distract the trooper with a Splat Bomb (or other sub) so it faces the bomb and exposes its rear to you, then shoot it.

After defeating, grab the power eggs and smash the boxes. Launch!

Checkpoint 2
You are faced with an arena and three troopers on top of boxes. From your staring point, make a trail by shooting out from the shelter.

You can use a Splat Bomb to distract the troopers, but they will not see you as you swim through the ink.

Get behind or to the side of the troops for an easy win. Note that when one dies, the others will be alerted, so act fast!

Clean up the field by grabbing all eggs surrounding the arena and destroying the red boxes, then launch.

Checkpoint 3
Fill in the trail already left for you, then swim down to a barricade to collect one power egg. Remember you can shoot to the other side to get the other power egg.

Like with Checkpoint 1, you need to distract the trooper with a bomb so they turn around, then shoot their back. Killing the trooper reveals the launchpad.

Checkpoint 4
Make a trail down to the first barricade, then shoot out to get the other two power eggs from the barricade.

As with the previous Checkpoint, use a bomb to distract the two troopers, then shoot them in the back.

Defeating both reveals the launchpad.

There are no other collectibles, so launch!

Checkpoint 5
There are six troopers circling three pillars (two each). You can:
 * Swim around a side
 * Destroy the centre boxes

Hide behind the first pillar if you get hurt. Then burst the remaining.

On top of the third, tallest pillar is the Sunken Scroll for the mission.

After getting the scroll, launch.

Checkpoint 6
Trail down to the end of the walkway, grabbing the three eggs and smashing the box containing the armor.

When collected, smash the box to the left and splatter the trooper circling the vault behind.

Cover as much of the ramp to your right as you can, then swim up and spatter the trooper standing guard on the right. Collect the egg on the way up.

At the top of the ramp is four troopers guarding the key. Remember the troops lose where you are when you dive into ink. Use Bombs to distract or simply shoot them all after destroying the boxes. There are two power egg boxes on the far right.

After splatting them, grab the key by covering the ramp with ink and swimming up.

Go back to the vault with the key and approach it to unlock it. It reveals a launchpad.

Final Checkpoint
There are two troopers circling the Zapfish. One has front-armour, the other does not. Fire down the ramp towards them, collecting the three power eggs on the way.

As before, distract the one with armour with bombs. After splatting both, destroy all boxes around. The stack of three (two red on top of brown) has the key.

When you approach the vault, three more troopers spawn in. Use a bomb or simply splat them. Unlock the vault and launch using the unlocked launchpad.

You are thrown to the top of the tower. Destroy the shield by firing at the Zapfish and then touch it to complete the mission!

Sunken Scroll
"Since time immemorial, a rare type of electric catfish known as the Zapfish has been prized by Inkling society as a source of energy. In fact, the entire city of Inkopolis is powered by a single 100-year-old Great Zapfish!"

- Sunken Scroll green

Location: Octotrooper Hideout's Sunken Scroll can be found on top of a pillar after Checkpoint 5. It is located inside a crate, and discusses Inkopolis' power source, Zapfish. It also depicts an image of the Great Zapfish, which has been captured by the Octarians.
