Atmospherics is the heart of Stationeers \u2014 and the thing that kills most new players. This guide covers the fundamentals of building a sealed, breathable, survivable base: the gases you’ll deal with, sealing rooms, making breathable air, managing pressure and temperature, the core gear, and the common ways crews suffocate.<\/p>\n\n

The gases in Stationeers<\/h2>\n
\n
Gas<\/th>Symbol<\/th>Role<\/th><\/tr><\/thead>
Oxygen<\/strong><\/td>O\u2082<\/td>Breathing & fuel oxidiser (fire risk pure)<\/td><\/tr>\n
Nitrogen<\/strong><\/td>N\u2082<\/td>Inert filler for breathable mix<\/td><\/tr>\n
Carbon Dioxide<\/strong><\/td>CO\u2082<\/td>Exhaled waste \u2014 must be scrubbed<\/td><\/tr>\n
Volatiles<\/strong><\/td>CH\u2084+<\/td>Fuel for smelting, power, chemistry<\/td><\/tr>\n
Nitrous Oxide<\/strong><\/td>N\u2082O<\/td>Powerful oxidiser; harmful to breathe<\/td><\/tr>\n

Breathable air is roughly 75% N\u2082 \/ 25% O\u2082; you need at least ~16 kPa of O\u2082 to remove your helmet safely.<\/figcaption><\/figure>\n\n

Seal the room first<\/h2>\n

Atmosphere leaks through any gap. A breathable room needs fully sealed walls, floors and ceiling, plus an airlock<\/strong> \u2014 two doors with a buffer between them so you don’t vent the whole room every time you step outside. If pressure won’t hold when you fill the room, you have a leak somewhere \u2014 check walls, frames and any unfinished tiles.<\/p>\n\n

What makes air breathable<\/h2>\n

Your crew needs oxygen at a survivable pressure<\/strong> (roughly 50\u2013100 kPa of breathable mix, with at least ~16 kPa O\u2082) and a comfortable temperature. Too little pressure and they can’t breathe; pure oxygen is a fire and health risk<\/strong>, which is why most players run a 75\/25 nitrogen\/oxygen mix rather than pure O\u2082. You also have to remove the CO₂<\/strong> your crew exhales, or it builds up and poisons them.<\/p>\n\n
