It's pretty easy to miss Splatoon's creepiest moments. Had someone not pointed it out to me, I never would have noticed!
For the most part, Splatoon is a bright, happy game. But YouTuber Siertes has discovered that, if you happen to linger too long on boss levels, you can hear some surprisingly hellish sounds inside of Splatoon:
I booted my own copy up, and found that these ambient sounds happen as early as the first boss level. It's possible that these sounds happen throughout every boss battle, but we're not able to make them out thanks to the music + our focus on trying to defeat the enemy. Some people note that they have heard these sounds before the boss battles actually start too.
What I'm wondering is: what exactly is it that we're listening to, here? The metal sounds seem easily explainable. You're underground. It could be, I don't know, pipes or something. But what about the strange moans around the :15 second mark? It sounds like someone, or someTHING is dying. Uh...
People have theories, all of which tie to the lore. The story, as you may recall, involves stealing back sources of energy called "Zapfish" from a species called "Octarians". The Octarian's civilisation isn't doing so hot as result, especially when you consider that their home is falling apart.
"Well this was you pretty much stealing an entire underground civilisation's last source of power," Viking the Shambling noted in the YouTube comments. "Thats falling floating platforms, a train derailing, and near total genocide happening. Splatoon's fucked up."
Who knows if these theories are right. I'll tell you one thing though: the sounds are damned eerie.
