Thin Air is discontinued as of 2026-03-31.

Check out the continuation projects instead.

Thin Air introduces hardcore air mechanics, making it harder and harder to breath the further you move away from the world's sea level. Both adventuring in caves as well as climbing tall moutains have suddently become quite dangerous if you don't bring a sufficient air supply! And don't even think of travelling to the Nether...

▶️ Below Y=0 and above Y=128, and in the Nether, you slowly lose air

▶️ In the End, there's no air at all

▶️ You can protect yourself with Potions of Free Breathing (which were renamed from Water Breathing), or with Respirators and Air Bladders

▶️ Create little pockets of tepid safety for yourself with Soul Fire, Soul Torches, or Soul Campfires. Or, restore your lungs with a Bottle of Soulfire

▶️ Safety Lanterns change color in your inventory and in the world to tell you the air quality around you. Or dye them for decoration!

▶️ Drowned will choke the air out of you on attacking

▶️ And as a fun bonus, right-click a torch to make it spew particles, perhaps to signal the exit to a cave

⏩ INSTALLATION REQUIRED ON CLIENT & REQUIRED ON SERVER

⏩ REQUIRES PUZZLES LIB TO BE INSTALLED (FABRIC & NEOFORGE)

⏩ REQUIRES FABRIC API TO BE INSTALLED (FABRIC)

⏩ REQUIRES FORGE CONFIG API PORT TO BE INSTALLED (FABRIC)

If available for a mod, configuration is possible directly from in-game using the mod menu (requires Mod Menu by Prospector to be installed on Fabric). Please note that on older Minecraft versions installing Forge Config Screens is also a requirement.

For manual configuration using an external text editor all files are found at .minecraft/config, named as MOD_ID-client.toml, MOD_ID-common.toml, or MOD_ID-server.toml, depending on the type of config. Not all types might exist for a mod, if any at all.

🌟 Thanks a lot to Petra for originally creating this mod as Miner's Lung. Thin Air is a simple port of the original project to modern Minecraft versions.

🌟 Thanks a lot to AlphaMode for porting Miner's Lung to Minecraft 1.19.2, providing the basis for Thin Air.
