10 Video Games That Were Secretly Horror Franchises

10. Subnautica

For the vast majority of us, swimming is a fun activity, be it paddling in some shallow water or zooming down water slides at speeds our ancestors would never believe possible.

That said, it's instinct to be a little nervous when you look into a deep body of water and realise you've no idea what's at the bottom, because you can't see it. This instinct takes Subnautica from a fun relaxing game where you discover countless strange and beautiful aquatic creatures, to a romp through phobia territory.

This would be bad enough if it weren't for the fact that some of the creatures you encounter really play on a fear of the unknown in dark waters.

When you're grabbed by malicious monsters, it's more or less a jumpscare half of the time, made worse by the fact they are generally the type of tentacled nightmare you fear from our actual ocean's depths, only ten times more deadly and frightening.

And, once you realise this will happen a decent amount, swimming through the depths can quickly take a more more terrifying tone, as you wait to be hunted down once more.
