Spaltoon 2: Octo Expansion brings in a load of brand new content for you to try your hand at, but be warned, it's not going to be an easy ride in the Deep Sea Metro for Agent 8. In this complete Splatoon 2 Octo Expansion guide, we'll be walking you through how to complete the main campaign of the new expansion, as well as detailing how to unlock multiplayer Octolings, so you can show off the latest and greatest of Splatoon's multiplayer characters online.
The Splatoon 2: Octo Expansion was one of the big features of Nintendo’s whole E3 2018 week in LA, which we were on the ground for. Head over to our full Nintendo E3 2018 recap page, where we’ll be going back over everything of note that the publisher announced, including Smash Bros., Fire Emblem, and more.
Splatoon 2: Octo Expansion Guide
The Octo Expansion was first announced for Splatoon 2 back in March of this year, and you can see the debut trailer for the expansion below. This marks the first paid DLC drop for the shooter, and as of right now we're unsure if Nintendo has any plans for additional expansions.
You play as Agent 8 all throughout the main story of the Splatoon 2 Octo Expansion, and this marks the first time in the series that we've been able to play as an Octoling. You could also see the Deep Sea Metro for the first time in this new trailer, which we’d be using to access all the brand new content. You can also see Pearl and Marina in new outfits during the trailer, which make the pair look quite similar to Biggie and Tupac.
Splatoon 2 Octo Expansion Campaign Guide
After you've purchased the Splatoon 2 Octo Expansion (see below for the price), and have updated your game, it's time to embark upon your journey as Agent 8. When you load up the Inkopolis Square, you'll get the prompt to investigate a mysterious alleyway.
At the end of the alleyway, select the option to begin the Octo Expansion, and you'll be asked to create your own Agent 8. As you can see from the screenshot just below, this can be either a boy or a girl, and both feature the brand new hairstyles for Octolings, introduced through the new expansion.
You'll now come face to face with Captain Cuttlefish, who's going to be your accomplice throughout the story of the Octo Expansion. Use the brief tutorial section after this to reacquaint yourself with the controls of Splatoon 2 if you've been away for a while (we sure had), and then it's time to board the Deep Sea Metro.
The Deep Sea Metro is basically the hub area while you're playing as Agent 8. You'll return back to the metro in between taking on one of the 80 challenge missions that the Octo Expansion boasts.
As for the challenges themselves, you'll use the screen just above to select which challenge you want to take on. You'll unlock new routes for the Deep Sea Metro through completing challenges, extending the track and allowing you to access even more challenges.
This is the core loop of the Splatoon 2 Octo Expansion. But a word of warning: it's really pretty difficult. We've struggled making it through the first few challenge missions alone, and they only get more difficult as they go on.
Every time you want to head into a new challenge mission, you'll have to buy your way in using credits, earning in-game. If you expend all three lives in a single challenge mission, you'll have to pay a fee to restart from the last checkpoint with all your lives granted back to you. It's definitely not for the faint of heart.
How Much Does the Octo Expansion Cost?
As for how to obtain the Splatoon 2: Octo Expansion content for yourself, you’ll firstly have to head to the Nintendo eShop on the Switch. Since the Octo Expansion isn’t listed as its own item on the eShop, you’ll have to go onto the product page for Splatoon 2, and then scroll down to other items underneath the main listing. You’ll then see the Octo Expansion product listing, and you can purchase it for $19.99/£17.99.
Once you’ve purchased the Octo Expansion via the Nintendo eShop, it’s time to update your copy of Splatoon 2. The Octo Expansion released for Splatoon 2 right around 7 pm PST/10 pm EST on June 13, and is out right now worldwide. The update required to install the expansion is a fair few megabytes, so don't be surprised if it takes upwards of 20 minutes to install.
The Splatoon 2 Octo Expansion features 80 single player challenge missions, and you should refer to the previous section of this guide for how to access them. The expansion also lets you play as an Octoling in multiplayer for the very first time, and you can see a sample of the new multiplayer characters just below.
As soon as you’ve unlocked the new DLC, you’ll also have a load of new cosmetic items for your Inkling or Octoling to equip. You can see a sample of the new cosmetic gear items just above, some of which will be delivered to you as soon as you've purchased the Octo Expansion.
How to Unlock Multiplayer Octolings
We've mentioned that the full campaign for Splatoon 2's Octo Expansion takes place across 80 difficult levels, but what are the rewards for completing all of these? At the very end of the campaign, you'll get to play as your very own customized Agent 8 in the standard multiplayer of Splatoon 2.
But, you don't actually have to complete all 80 levels in order to beat the campaign. Instead, you only have to find the four glowing points on the Deep Sea Metro map. Once you've found these glowing points, you'll then have to beat the incredibly tough boss waiting for you there. Defeat all four bosses, and you'll beat the campaign, unlocking your Octoling for play in the multiplayer side of Splatoon 2.
This is all the information you need to access all the brand new content that the Splatoon 2: Octo Expansion has in store. We’ll make sure to update this guide in the future, when we’ve uncovered any additional features and secrets that the brand new Octo Expansion holds.
