How to Craft an Air Tank
Craft Air Tank at the Fabricator
You can craft the Standard Air Tank at the Fabricator inside your base or Lifepod. The Air Tank blueprint is unlocked by default, so you only need to gather the required materials to craft it.
Materials Needed to Craft the Air Tank
| Material | Amount |
| Titanium | 2 |
| Rubber | 1 |
| Silver | 2 |

Titanium is a common material used to craft tools and equipment. You can find Titanium near the Lifepod.
How to Get Rubber
Rubber can be crafted at the Fabricator using 2 Lucifer Rotsacs.
How to Get Lucifer Rotsac
Lucifer Rotsac is easy to spot because it glows bright orange. It can also be found near the Lifepod inside a Cradle Shootroot.
How to Get Silver
| Silver Coordinates | -339407, 411237, -4410 |

Silver is a bit harder to find since it appears further from the Lifepod. Some can be found inside caves. The coordinates for one such area are listed above.
| Note! | You can check your current coordinates by pausing the game and checking the bottom-right of the screen. |

How to Unlock Air Tank Upgrades
Find Blueprints in Data Boxes
To upgrade your Air Tank, you first need to find the blueprint for the High Capacity O₂ Tank. This blueprint is typically found in Data Boxes located in wrecks or abandoned Seabases. Once you have the blueprint, you can craft the upgrade at a Modification Station.
