Iron Lung

Okay, but imagine you're a deep sea creature who doesn't interact with light. You find a little weird metal bubble. You're observing it, and then suddenly it flashes right in your eye because the shithead human inside takes a picture of you. I think I'd freak out too.

"...So you will be welded inside..." That's not a submarine, that's an iron casket.

13:14 The realization that jack had when he saw the thing in the picture and thought "that almost looks like a huge angler fish" then he took another picture after in the same place and it was just gone and he realized that was an actual living creature watching him was terrifying. at the end also you see that it looks like an angler fish that kills you, and you realize it was stalking you the entire time

While this game is scary, the most terrifying aspect for me is the 'ghost light' they describe in the beginning. I read that if the sun were to suddenly vanish, it would take 8 minutes for us on earth to see that it's gone, as light takes 8 minutes to reach us from the sun. The same would apply to a star that's 100 light years away, or a galaxy that's 10 million light years away. In this universe, if every star vanished, you'd still see them in the sky for a time. Eventually, the last light that every star emitted would reach your eyes, and they'd fade away forever. The stars you'd see truly are ghosts.

I love how despite the game only being in a small cramped space, there is still an entire world building concept. The thought that outside of that ocean planet is nothing but dead stars is amazing background.

And what he didn’t notice, is that whenever the sub was “hit” and it shook, the coordinates would change drastically, as if he had been teleported

The scary thing is that, the eye you see in the picture looks WAY bigger than what attacks you in the end, SO that implies that there is an even BIGGER creature out there 😰

This whole game could honestly be a whole SCP scenario all on its own. It has all the right premises for it.

One detail I didn't fully appreciate about this game at first was the fact that this was the fourth blood ocean they've discovered. Once is an anomaly. FOUR implies a widespread occurance.

“It’s terrifying relying only your instruments” Me, a pilot working on getting my instrument rating: it’s even worse in real life

Another absolutely terrifying part of this game is the lack of a backstory. The game leaves you with more questions than answers. For instance, where does all the blood come from? Based on the seemingly manmade structures, there seemed to have been intelligent life before, and this part of the moon probably wasn't an ocean yet. Was the blood coming from its inhabitants? Is the presence of blood oceans and the apparent wipeout of what seemed to be intelligent life connected to the quiet rapture? What is that strange electrical thing? Is it connected to any of this? What caused the stars in the universe to die? The quiet rapture is, in itself, an extremely horrifying and depressing concept, even more, if nothing, and no one is behind it. The thought that we have nowhere to go after Earth and the solar system dies and there is nothing we can do about it is scary, even more than any deep-sea monster. Take all of that and combine it and you have an unforgettable experience. That is horror.

This game needs a sequel. This game takes the saying “Less is more” to the fullest. Edit: I realize my comment contradicts itself thanks to all you guys. Guess I made an oopsie 💀

"This is terrifying to only rely on your instruments"... That's literally how big submarines navigate. Makes you realise how hard their job is!

When your ships "suddenly stops" you actually get teleported, just look at the coords at 24:06 :D pretty sure u went into one of those portals, also (apparently) there is a lot to find if you go out of your to look for it instead of following the map

This is such a good game. They should make a movie out of it.

This game is a prime example of how crucial the use of terror is in a horror game. For clarification, HORROR is the immediate reaction to extreme stimulus; flinching or shouting at a jumpscare. TERROR is a passive reaction to subtle stimulus; being put on edge by strange sounds or imagery. In this case, the terror is fueled by many things: the restriction of sight through your camera that takes a few seconds to load, the moans implying something's out there, the weird noises at the portal node, the bumps, and of course seeing the beasties, just once, in the camera. All of this works in tandem to invoke a heightened sensitivity to stimulus, so when the jumpscare finally comes, the stimulus is perceived to be more extreme than it really is, making the jumpscare, well, more scary. When done well, it results in a REALLY good horror game, as the scares are always more intense. It's the main reason why this game is so highly praised: it ALL sets you up for that one scare, and it does it right.

As someone who is going to be starting college for marine biology, this made me rethink my career choice

For those who didn't notice, the structures scattered across the trench seem to vaguely resemble the eldritch city of Raleigh based how Lovecraft described it

"What if at one point I take a picture and there's a face there" The way I smiled knowing I just came back from Mark's gameplay 😭😭

The jumpscare at 25:12 with the eye ball is perfectly crafted. This game is something else. Jack's reaction is hilarious
