One of the most unique horror games I've played. Masterful story, build up, atmosphere, and (some) jumpscares. It is short, it has kinda boring controls, and, specially, expensive. But buy it on a sale, you wont be disappointed.

Pros: - Although the entire gameplay takes place inside a 1x1 submarine and the player can only see the outside world through images, the atmosphere in the game is both fantastic and spooky and there is always a feeling of creepiness and discomfort. - An interesting way of movement where the player relies on the map and coordinates without even seeing where he is - Jump scares are rare and amazingly well timed. Cons: - The game is still a little too short for the reason that the plot and the world in which the player is placed is great for the further development of the story - The tutorial is not the best, and it took me a while to figure out how to move as best as possible Rating: 8.5/10

“Diving into the depths of the ocean, I felt like I was entering a realm of nightmares, where terrifying creatures lurked in the shadows.” This and many more quotes from Death in the Water 2 fit perfectly with Iron Lung. In this short horror game, you are alone in a tiny submarine and must explore the depths and mysteries of a Blood Ocean. And this is where the game's great strength comes to the fore. Its atmosphere. Iron Lung offers an oppressive, threatening and dense atmosphere. Just you alone, in this iron coffin with your fears, your paranoia, your isolation and what lurks out there in the dark abyss. The whole thing is underpinned by the sounds of the submarine, the deep sea and the photos you take during your exploration. An experience not to be missed.

Intro There are a lot of horror games in gaming world. From popular ones like Slender: The Arrival or Outlast to small ones. But what happens if we will mix space, water world and horror gimmicks that some people will have thalassophobia. Polish programer, Dawid Szymański, decided to do it. He created an small indie game called Iron Lung, a game that went viral on its arrival. But let's ask, is it really worth such praise? Let's find out. Story In the space far far away, there is a planet filled with bloody ocean. For unknown reason, many submarines and people have dissapeared without a trace. We are playing as a driver of SM-11 and our mission is to uncover the what happened there and bring evidence to the world. The story sounds simple enough but there is not much to talk about it. The story is quite vage and it's not said straight to the player. I am fully aware that after recent update, we can type one console some stuff to get the information that is related to the story but you have to know commands to it. I am not complaining that the story is kept in secret but it leads to many questions. Who is the specifc SCP, who sent us, which sector we are, what was the story of this planet, what caused it to be filled with ocean of blood? Questions are coming and we don't have any answers. Gameplay What made me convinced to play this game, was the gameplay. The gameplay is simple but done very nicely. We have on the map the location of nodes that we have to reach them on specific coordination. After reaching it, we have to make a photo of each one of them. But reaching them is not easy. You are using only arrows on the submarine control which are up and down. Up allows us to move forward, and down to reverse. We change direction by changing the angle. And this is important because the photos have to be made from the specific angle. We also have a radar that indicates when something is close to us. What is more interesting, is that you don't see a damn thing. You have to use your coordination skills to find where you are and how to go and be aware of your surroundings. The gameplay is simple but actually effective and it made me to enjoy the game from it. Atmosphere The atmosphere of this game is also nicely made. It's pure silent but sometimes we can hear some noises which makes us a bit tense. The music is also creepy and uneasy, but unfortunately there is not much of it. But this builds the atmosphere of you, swimming on dead bloody ocean and having you on guard on wide open space where you don't know what can attack you. Conclusion Iron Lung is quite a unique game. As a game for a couple hours, is worth to play. The controls are nicely done and the atmosphere is done well. However, the lack of straight story is a big disadvantage of it. This is a good game for one seating but not worth to come back. So, is this game worth to praise? Yes, but not that much as I hoped. Great that at least was inspirational because Mark Fischback, AKA Markiplier makes his own movie based of it so, that could build its popularity. But still, I recommend to play it. The price for such indie game is very fair and if you like independent indie games and horror stuff, it's worth to try.

100 % in 1,5 hours, didn't refund because this developer deserves every penny. The graphics make the atmosphere of the game phenomenal. Only negative is that I cannot relive this the first time ever again.
