Beyond Oxygen
With Beyond Oxygen installed, players can seal an area, pressurize it with liquid oxygen from a vent and build ships and submarines that hold air.
What it does
Beyond Oxygen adds an oxygen system for space and underwater builds. A vent block pressurizes a sealed area once liquid oxygen is pumped into it, and an oxygen bubble generator supplies air wherever no sealed space exists. Liquid oxygen can be filled into tanks from Mekanism or Ad Astra recipes, which are listed in JEI. Oxygen harvesters gather oxygen passively from crops and leaves in a pressurized environment.
The mod also covers temperature. Thermal regulators, cryo suits and a cryo-bed let players survive heat and cold, and the cryo-bed sets a ship-persistent respawn point that still works while a ship travels between planets. Support for Valkyrien Skies allows sealed air pockets on moving ships. Beyond Oxygen requires Mekanism for its built-in recipes and needs power from RF or another FE-compatible source. It is open source under the GNU General Public License v3.0 only.
Beyond Oxygen is published for Forge across six release versions, 1.20.1 – 1.20.6, with 0.12.8 for 1.20.1 as the latest file. A server running it needs every connecting player to have it too. Public source code, an issue tracker and a wiki are linked from the project.
Key features
Sealed air pockets
Sealed areas hold pressurized air once a vent has been supplied with liquid oxygen, which allows enclosed bases and ship interiors.
Oxygen bubble generator
A generator supplies air without needing a sealed space, so it can be placed where the vent cannot work.
Temperature protection
Thermal cryo suits, a thermal regulator and a cryo-bed help players withstand heat and cold on other worlds.
Ship-persistent respawn
The cryo-bed sets a respawn point that stays with a ship, including while it travels to other planets and dimensions.
Functional submarines
Players can build submarines that use the oxygen system to stay underwater for long periods.
Compatibility
