What if they add tritium, it would be used in nuclear stuff and could be made by shooting neutrons at lithium , also deuterium if you shoot protons(not the deuterium OXIDE because the OXIDE is already in the game) liquid hydrogen for rockets and nitrogen, it could be used to prevent the whole world from burning (just likd real life) yeah oxygen burns so easly...
We can prevent this by changing the names of LN2 and NICE to coolant and solid coolant respectively; there have been many proposed abbreviations for said elements.
