About this project
What does Beyond Oxygen add?

The Hot & Cold Update is here!
Features:
**New Block: The Cryo-Bed!**Sleep anywhere, anytime- The Cryo-Bed is here! An old reliable fridge, retrofitted with advanced cloning technology- Should your original be lost, a clone will surely take its place! Ship-persistent respawn point, that works on Starlance ships- even when travelling to space, planets, and beyond!
New Armor Sets: Thermal and Cryo
Something's got you shivering, or you can't take the heat? Craft a space suit set to suit your needs! That's right, Cold Sweat compatibility!
New Item: Thermal RegulatorNow, the thermal and cryo suits can keep you comfy, but what's going to warm up or cool down your over-engineered space base? That's right, the Thermal Regulator! Craft it, apply it to your oxygen supplier of choice- (Shift right-click it onto a vent or bubble generator), and you're perfectly tepid all of a sudden! Technology.
Description:
This mod adds a (mostly functional) oxygen sealing mechanic, that SOMEHOW! is compatible with Valkyrien Skies. Additionally, it adds the ability to create functional submarines (mostly functional submarines, to be precise)
How To Use:
Fill tanks with Liquid Oxygen(Mekanism) or Oxygen (Ad Astra), use JEI for recipes, pump liquid oxygen into the vent block to PRESSURIZE AN AREA! THE FUTURE IS NOW! The Oxygen Harvester requires crops or leaves in the sealed area, to passively gather oxygen from a pressurized environment- It does require RF or any other FE-compatible source of power. The Cryo-Bed is a dimension- and ship-persistent respawn anchor, that is, it can respawn you in the nether, on your moving VS ship, or in any other dimension. The Oxygen Bubble Generator is much like a vent, but it doesn't require a sealed space to work- Just supply it with oxygen, give it some FE power- and you're good to go.
IMPORTANT: Mekanism is needed for built-in recipes, but it's not required , since CraftTweaker exists.
To make a dimension unbreathable, or to add gear that counts as a spacesuit, add it to the config file. Feel free to use in your modpacks! If you are looking for a config for Starlance use this:
