Iron Lung Game Review


At a point in time, after all stars and planets in the universe have vanished in an event known as The Quiet Rapture, humanity continues to live on decaying space stations and cobbled-together submarines like SM-13 – sent on missions to explore deep within oceans filled with blood.


Iron Lung is an indie horror game set after The Quiet Rapture, a catastrophic event in which all habitable planets vanished, and people began living only on space stations or starships. You play as a convict sent to explore an ocean of blood on AT-5 using submarine SM-13 (nicknamed Iron Lung). Unfortunately, its forward window has been shut to facilitate deep dives; instead, navigation occurs using sensors and cameras on the vessel.

As the player explores, they will come face-to-face with a terrifying monster known as a Monster that hunts them in an alien environment. To progress further in their game, players must photograph points of interest, such as skeletons or inanimate objects in ocean trenches or cave systems, to move further; additionally, they must deal with a fire that breaks out in the back of an Iron Lung and its back hearing something being crushed against it – two threats which must also be battled off simultaneously!

Over an hour’s playtime, the player will take several photographs during this game’s runtime. They may experience some crashes with their sub, yet this shouldn’t be taken as an indicator of poor skill or mechanics; restarts aren’t usually a big deal, anyway! Repeated crashes help players navigate between each photograph more confidently as they become familiar with its location on the map and its significance to them as part of a whole picture.

Iron Lung is a minimalistic horror game that succeeds through its straightforward gameplay mechanics and mastery of sensory deprivation. Its minimalist approach stands out in an industry awash with overcomplicated video games, which often focus too heavily on adding extras without considering their effect on immersion; Iron Lung serves as a prime example of creating tension through immersive storytelling that forces players to confront themselves alone as they progress through its narrative.


This first-person survival horror game offers an ominous atmosphere and a sense of impending doom. As a prisoner aboard a submarine, players must navigate an alien ocean while evading an unpredictable monster. This title stands out among similar games by having many distinct elements; its difficulty increases over time as water fills in on them and monsters attack periodically.

Iron Lung was developed by David Szymanski and released for public consumption in 2022 to critical acclaim among gamers. YouTuber Markiplier became particularly fond of playing it and sharing his experience on his channel; later, he planned on adapting it into a movie adaptation.

Iron Lung creates an immersive horror experience in a tiny area yet still manages to scare. The player finds themselves inside an old and rundown submarine not designed for exploring bodies of water at this depth, leaving only a window sealed over for exploration. As such, navigation becomes extremely challenging: players rely on proximity sensors, coordinate reading, and maps for their position, while sonar warns them of obstacles as any collision causes an explosion.

The game’s art style is truly spectacular and adds to its creepiness. The low-resolution graphics would fit right in at any late 90’s video game, and its sense of uncanny perfectly fits its genre. Additionally, this experience has multiple jump scares without becoming the focus of fear for most of its duration.

Iron Lung is a free-to-play PC game compatible with Windows 7/8/9/10 that requires at least a 2.00GHz processor and at least 1GB of RAM to operate smoothly. An official system checker and gaming PC setup tool is available on its official website to test the compatibility of your system and device with this game. A speaker from Iron Lung denied copying Mark’s movie concept by noting they had already begun working on developing this game before becoming aware of his plans to create a film adaptation of his novel.


Iron Lung stands out with its outstanding sound design; Iron Lung is no different. The game’s dreary atmosphere and chilling audio effects create a thrilling environment that keeps players on edge, while its unique gameplay adds suspense and enhances fear factors.

This claustrophobic survival horror game places players as a convict on a dangerous mission through an ocean filled with alien structures and peculiar life. They must navigate these uncharted waters using only a map, proximity sensors, and a grainy still camera before being forced through terrifying events that threaten its demise and the loss of all crew.

Iron Lung is an engaging scare-fest with limited resources and short playing times that will leave players feeling unnerved and unsettled. The atmosphere and sound design combined create an exciting experience worth the admission price; its only drawback is the lack of storyline, which does not compromise the overall quality of the gameplay experience.

David Szymanski is well known for creating unsettling experiences through minimalist mechanics, with games such as DUSK, Fingerbones, The Moon Silver, and A Wolf in Autumn all using slow-burn tension to instill a feeling of fear. Iron Lung employs this same strategy with its fixed camera perspective, making its horror even more effective.

The story of this game takes place in a distant future when all inhabitable planets and stars in the universe vanished suddenly due to an event known as The Quiet Rapture. Years later, survivors struggle to maintain humanity on space stations and barren moons; one moon contains an ocean of blood believed to be humanity’s last hope before all stars eventually vanish forever.

Mark Edward Fischbach (Markiplier), one of YouTube’s premier gaming channels, will adapt the 2022 video game Iron Lung into a film adaptation that premiered shortly after its release on his channel shortly before appearing online as a movie. Fischbach will write, direct, and star in his movie version.


The game takes place shortly following the Quiet Rapture event. All stars and habitable planets suddenly vanished from our universe, leaving only humans living on space stations and barren moons as survivors. A mysterious ocean of blood has recently been discovered on one of these moons; humanity’s remaining government, The Consolidation of Iron, has assigned you to explore it in an Iron Lung submarine explicitly built to explore it, with oxygen levels rapidly diminishing as you progress more profound underwater survival seems increasingly unlikely.

To fulfill your mission and gain your freedom, you must navigate the depths of this blood ocean to photograph points of interest that could provide essential resources for Federation survival while remaining on guard against a massive sea creature who seems intent on destroying your submarine. Your ramshackle sub only features GPS technology as well as essential navigational devices; your single-shot exterior camera warns you of nearby obstacles by emitting sound – colliding with walls or other obstructions results in its hull rupturing, leading to its quick demise and swift death.

This experimental minimalist gameplay delivers an immensely immersive experience. The claustrophobic environment feels alive, constantly threatening to swallow you whole. Your entire body tenses as you desperately scrabble for control to avert disaster; each photo taken can bring hope and anxiety as it opens a window into some evil being’s den of terror.

Iron Lung is an impressively terrifying experience demonstrating slow build’s effectiveness. While most horror games rely on jump scares or cheap tricks for suspense, this indie title relies heavily on creating tension through minimal resources – such as low-resolution visuals and simple navigation systems to create an unnervingly unsettling environment that keeps players on edge throughout its hour-long runtime. Furthermore, it also boasts an eerie and haunting score by composer James George that adds another layer to this frightening tale.
