Iron Lung screenshot
Last checked:
Iron Lung takes around one hour to finish, with most players landing between 45 and 90 minutes depending on how carefully they navigate. The game has no side content, so a completionist run adds little more than a second trip through the sea of blood. All figures below apply as of October 2026.
Iron Lung length by playstyle
| Playstyle | Typical time | Notes |
|---|---|---|
| Main story | Roughly 1 hour | Single linear route to all photo coordinates |
| Main plus extras | Around 1.5 hours | Reading every log, replaying after the ending |
| Completionist | Around 1.5 hours | Steam achievements add minimal time |
| Speedrun (any%) | Well under 15 minutes | Memorised coordinates, no detours |
These are averages of the kind collected on HowLongToBeat, not fixed values. Your first run will almost certainly sit at the longer end because you cannot see where you are going.
What fills the hour
You pilot a tiny submarine across an ocean of blood on a dead moon, steering by coordinates and a proximity map rather than a window. The task is to photograph a fixed set of locations and return, and the whole experience is built around that blind navigation. Every photograph you take forces a pause while you check the grainy result, and those pauses are where the runtime goes.
| Segment | Share of a first run | Why it takes that long |
|---|---|---|
| Learning the controls | 10 to 15 minutes | No tutorial beyond the opening briefing |
| Travelling between coordinates | 30 to 45 minutes | Slow submarine, map reading, collisions |
| Taking and reviewing photos | 5 to 10 minutes | Each photo develops before you see it |
| Ending sequence | Under 5 minutes | Scripted and unskippable |
Why runtimes vary so much
The single biggest factor is collisions. Scraping a wall slows the submarine and tends to send you backward, so a cautious route can easily add 20 minutes over a confident one. The second factor is panic. The game relies on dread rather than scripted chases, and plenty of players stop, listen and wait when nothing is actually happening.
Second runs drop sharply. Once you know the rough layout, a replay settles close to 30 minutes, which is why the completionist figure barely exceeds the main story figure.
Good to know
Keep a pen and paper beside you. Writing down the target coordinates and your current heading cuts the runtime more than any in-game trick, because the ship offers no route memory.
Game runtime versus the film runtime
Searches for Iron Lung runtime now split between the 2022 game and Mark Fischbach’s 2026 film adaptation. The two are not comparable in length.
| Version | Format | Runtime | Released |
|---|---|---|---|
| Iron Lung (game) | PC, Switch, PS5, Android, first-person | About 1 hour | 10 March 2022 |
| Iron Lung (film) | Theatrical feature | Around two hours per theatre listings | January 2026 |
The game’s brevity is deliberate. David Szymanski launched it at 5.99 USD on Steam, later raised to 7.99 USD in December 2023, and its rating on store pages reflects a short, dense horror piece rather than a campaign you return to over weeks.
FAQ
Is Iron Lung really only an hour long?
Yes. Most first-time runs finish between 45 and 90 minutes, and no post-game content exists beyond rereading the logs.
Does Iron Lung have multiple endings?
No. There is one ending, so replaying for alternate outcomes does not extend the runtime.
How long does Iron Lung take to 100 percent?
Around 1.5 hours. The Steam achievements line up with normal progress, so a careful single run plus a short replay covers them.
Is Iron Lung on consoles?
Yes. As of October 2026 the game is available on PC through Steam, as well as on Nintendo Switch, PlayStation 5 and Android. The itch.io listing is no longer available.
