. I have followed this game since its 2022 launch, and the reception has only grown stronger over time.

The premise is simple and effective. You pilot a cramped one-man submarine nicknamed the Iron Lung through an ocean of blood on a barren moon, using only a map, proximity sensors, sound, and a grainy external camera to find your way. Destructoid called it “the perfect short-form horror experience” in a 9/10 review, and Vice described it as one of the most terrifying games its reviewer had ever played.

Iron Lung
launched on Windows on
March 10, 2022
, then reached
Nintendo Switch
on December 19, 2022,
PlayStation 5
on October 15, 2025, and Android on December 12, 2025. David Szymanski, the solo developer behind
DUSK
,
The Moon Sliver
, and
Squirrel Stapler

, built the game after a visit to a Loch Ness museum. It sits comfortably alongside his other short horror experiments.

The game is intentionally short, built to be finished in a single sitting of about an hour. A free Iron Lung Mode update from October 2023 replaces in-game textures with Markiplier’s face, a nod to the film that followed. The

Iron Lung
price rose from
to
in December 2023, though the sale price still regularly dips lower. It is also part of a 9-game Szymanski bundle on
Steam

for anyone who wants his full catalog.

low. That discount shows up in most major seasonal sales, so waiting for the next one is a reasonable bet if you do not mind a short delay. If you would rather skip the wait entirely, the Snakzy method below gets you a copy without spending anything.

Historically,
is as low as
Iron Lung
has gone since its price increase, so this is close to the best deal
Steam
has ever offered on it. Szymanski’s other games follow a similar pattern of steep seasonal discounts during the
Steam
Summer and Winter sales, so expect this title to follow suit. None of that matters much if you take the
Snakzy
route, since the entire point of that method is that the
Steam

price becomes irrelevant once your coins cover it.

Iron Lung System Requirements

Iron Lung is one of the lightest games on Steam, built to run on almost any PC from the last decade. You will not need a dedicated graphics card to play it, and the install takes up barely any drive space compared to most modern titles.

without trouble, since the minimalist visual style keeps the engine load light throughout every dive. This is one of the rare horror games where hardware is never the reason to skip it, so a budget machine plays it exactly the same as a high-end rig.

Iron Lung Mechanics

The core loop puts you inside a single cramped room aboard the Iron Lung submarine, piloting entirely blind. You punch coordinates into a console, watch a set of proximity sensors for anything too close, and creep toward marked locations scattered across an incomplete map of the blood ocean.

Your objective at each marked point is to snap a photograph with an external still camera. Those grainy snapshots are the only glimpse you get of what is actually outside the sub, and each one escalates the dread a little further. There is no combat, no difficulty setting, and no new game plus. The free Iron Lung Mode update is the one official modifier, replacing in-world textures with Markiplier’s face.

The design tension comes from total sensory deprivation set against the need to keep moving forward. Leaks spring, alarms blare, and there is always the possibility that something enormous is circling just outside your hull. Every system in the sub, from the sonar ping to the depth gauge, exists to make you second-guess what you cannot see.

Compare this to Szymanski’s fast-paced DUSK, and you see his range as a designer. This is horror built through restraint rather than action, exactly what Vice praised in its review. There is no combat to fall back on when tension spikes, so the only real tool you have is patience.

Iron Lung Top Features

Blind navigation.

You never see outside directly. You steer using the map, sound, and proximity sensors alone, and your imagination fills in the rest.

Grainy camera photography.

A primitive external still camera is your only window to the ocean, delivering some of horror gaming’s most infamous jump reveals.

Oppressive sound design.

An original soundtrack inspired by Aubrey Hodges’ Doom 64 work keeps the pressure suffocating from start to finish.

One-sitting dread.

Iron Lung is designed to be finished in under an hour, a complete horror arc with no filler.

Iron Lung Mode.

A free official mode swaps in-game textures for Markiplier’s face, a nod to the 2026 film.
