Iron Lung (Chinese Version)

Iron Lung is a short horror submarine game from the developer of DUSK, The Moon Sliver, and Squirrel Stapler, and has been adapted into a film by Markiplier, set to release in 2026.

The game takes place entirely inside a claustrophobic one-person submarine called the Iron Lung. Players must feel their way through a sea of blood, photograph key locations, and pray that the monsters lurking underwater don't find you.

The submarine has only one porthole, which must stay closed due to deep-sea pressure, so players can only navigate using an incomplete map, a proximity sensor, sound, and a primitive external camera. This camera can be used to take the photos needed to complete the mission, or to get some blurry, low-resolution glimpses of the outside.

Success requires players to have ample resources and plenty of patience.

Story summary:

Decades ago, all known stars and habitable planets, along with all life on them, mysteriously vanished, leaving behind a universe of empty asteroids and dead moons. The remnants of humanity are only those who happened to be on space stations or starships at the time. As supplies gradually ran out and infrastructure fell into decay, the survivors spent the following years frantically searching for any remaining natural resources. Until now, they have found nothing...

Then, on an otherwise barren moon, people discovered a mysterious anomaly known as the "Blood Sea" (as the name suggests). This was not the first "Blood Sea" found since the universe disappeared, but preliminary scans showed potentially useful anomaly zones in a deep-sea (or rather, "beneath-the-blood-sea") trench that required further investigation.

And you are the unlucky one, assigned to pilot an old submarine cobbled together from rusty space station parts to go investigate.

Find the marked locations, photograph whatever you find there, and try to complete the mission before the submarine collapses around you... or before something lurking in the blood finds you...
