Iron Lung: Cheat Codes Guide — All Terminal Commands
Want to experiment with Iron Lung beyond the standard claustrophobic horror experience? Following the official Cheats Update, the game now includes a set of built-in terminal commands that let you toggle visual filters, add equipment, and even activate a special guest mode. This guide covers all cheat codes and explains exactly how to enter them through the submarine's on-board computer.
How to Enter Cheat Codes in Iron Lung
All cheats are activated through the computer terminal located at the back of the submarine. There is no external menu or console — you simply type commands directly into the terminal interface.
Step-by-Step Instructions
- Launch Iron Lung and start or load a game.
- Navigate to the back of the submarine where the computer terminal is mounted.
- Interact with the terminal to bring up the text input screen.
- Type the cheat command exactly as shown below.
- Press Enter to activate the effect.
Note: Cheat codes are stackable, meaning you can activate multiple cheats at the same time. If you want to return to the default state, use the clear command listed below.
All Cheat Codes for Iron Lung
The following commands are confirmed working across all platforms. Enter them into the terminal precisely as shown — all commands use lowercase letters only.

| chclear | Clear All Cheats | Deactivates every active cheat and returns the game to its default visual and gameplay state |
| chnoir | Noir Mode | Activates a black-and-white visual filter for a classic horror aesthetic |

How to Combine & Clear Cheats

To remove every active cheat at once, simply type:
chclear
This instantly disables all visual and gameplay modifications without needing to restart the level or reload your save.

Frequently Asked Questions (FAQ)
Where is the terminal located?
The terminal is mounted on the wall at the back of the submarine. Walk to the rear of the vessel and interact with the computer screen to open the input prompt.
Do cheats disable achievements?
Using the built-in terminal cheats does not lock you out of achievements. Since these are official developer commands, you can experiment freely without worrying about your trophy progress.
Can I use cheats on console versions?
Yes. The terminal is accessible on PC, PlayStation, Xbox, and Nintendo Switch. Simply navigate to the back of the sub and type the commands using your controller or keyboard.
Why is my cheat code not working?
Make sure you are typing the command in lowercase exactly as shown. The terminal does not recognize uppercase letters or typos. Also confirm you are entering the code at the computer terminal, not in a menu or pause screen.
Can I stack every cheat at once?
Yes. All seven cheats can be active simultaneously. However, some visual modes may overlap in unexpected ways. If the screen becomes too distorted or you want to start fresh, use chclear to reset.
Are these cheats safe to use?

Is there a way to see the full list of terminal entries?
Beyond cheat codes, the terminal accepts various lore-related keywords such as iron lung, eden, the quiet rapture, and blood oceans. These provide background information but do not modify gameplay.
