This guide will let you know how to get Sulphurine in No Man’s Sky.
Sulphurine is just as simple to find as any other gas, as you can only find it on certain types of planets. The planet types you’re going to be looking for are scorched/fiery or desert/abandoned planets. On these planets, you can harvest sulphurine.
Once you find the planet type that you’re looking for, you can gather sulphurine in two ways. The first way you can do it is by finding gas hotspots with sulphurine as the resource and placing a gas extractor near it to gather the sulphurine.
The other way you can get sulphurine is by placing down an atmosphere harvester which will also gather sulphurine when it’s fueled.
