How to Play Iron Lung
Navigate the Blood Ocean
You must move through the dark liquid using a simple map and a compass. You can change your speed and turn the vessel to reach target locations. It is important to stay away from the walls of the trenches. You must check your sensors constantly to avoid a crash.
Use the External Camera
The only way to see the outside world is by taking still photographs. You must reach the exact coordinates marked on your map first. Then, you press a button to capture a grainy image of the ocean floor. These photos show eerie structures and mysterious life forms hidden in the blood.

Listen for Danger
Sound is your most important tool for survival in this dark world. You will hear the metal walls creak under the heavy pressure of the blood. Strange noises might signal that something huge is moving outside your hull. You should pay close attention to the proximity pings to judge your distance from obstacles.
