Splatoon 2‘s Octo Expansion, which includes the ability to play as Octolings, doesn’t release until this summer. However, hackers have managed to make the Octolings playable early. A couple of YouTube videos were released that demonstrates the Octolings in multiplayer matches. Not all of the content is in place. For example, sound effects are missing. Nevertheless, both male and female Octolings were showcased in the videos. The videos can be seen down below.
