    Majority of players don't understand how Atmosia works, or how they should play as an atmos tech. I've made this guide so that people can quickly and easily learn what you should do every round, as well as some of the cooler advanced stuff. If you have any questions, or anything you would like me to add, please feel free to ask. Over time I'll add more stuff, I'd rather have the guide up while its only partially completed so that people can learn from whats already here.

    What atmosia does by default: Waste air comes in, gets filtered slowly, fresh air gets pumped out slowly

    What we want it to do: Pump waste gas in quickly, cool it down, filter it quickly, keep a medium pressure of fresh air in the pipes

    Do the following things at the start of EVERY round.

    #1 Go to air output, set the gas pump to 1000 kpa

    #2 Replace the gas pump at waste input to a south-facing volume pump and turn it on (leave it on max)

    #3 Go to each air filter and turn it to max

    #4 Go to the nitrogen, oxygen and air mix gas pumps and turn them all to max (4500 kpa)

    #5 Open up the computers for all of those same gasses, and set the output to 4500 kpa

    #6 Remove the gas pump between the custom mix freezers and waste pipes, and replace it with a horizontal pipe. Change the heater into a freezer (Screwdriver, crowbar, screwdriver the heater chip, put everything back in frame, screwdriver twice, wrench once to turn pipe, screwdriver again) , then turn both freezers on to the lowest temperature possible.

    #7 Go to all of the important rooms/hallways, unlock air alarm with ID, set operating status to contaminated. Afterwards, lock the air alarm with ID. Since this is mostly time consuming and boring, just do the important areas.

    #8 Don’t remove the mix tank to distro gas pump. Its against the server rules. Besides, its more fun this way.

    #1 Go to air output, set the gas pump to 1000 kpa

    - By default atmosia pushes out only 100 kpa of air. To reliably refill rooms that have lost air, you'll need a higher pressure in the air pipes.

    Some people recommend that you put a volume pump on max here, and push the pressure all the way up to 9000kpa. I personally dislike doing this, to the point of swapping it to gas pumps if I see anybody doing it.1000kpa is more than enough for all you need.
    Pros: Low pressure rooms can be refilled quickly
    Pipes when wrenched will send people flying at high speeds
    Hard to flood station with plasma quickly

    Cons: 1000kpa can refill low pressure rooms just as fast
    Unwrenching pipes won't hurt you if you don't hit a wall or window
    If an air alarm is compromised, entire sections of the ship can be overpressurised in under a minute
    Draining distro pipes will take a long time
    No changes to distro configuration can be made without potentially harming yourself

    #2 Replace the gas pump at waste input to a volume pump and turn it on (leave it on max)

    #3 Go to each air filter and turn it to max output

    - These two steps max out the filtering system

    #4 Go to the nitrogen, oxygen and air mix gas pumps and turn them all to max

    #5 Open up the computers for all of those same gasses, and set the output to 4500 kpa

    - The breathable air mix will be mixed faster, before being sent up to the air out pipes.

    #6 Remove the gas pump between the custom mix freezers and waste pipes, and replace it with a horizontal pipe. Turn on the freezer and set it to coolest setting

    - Cooling a gas reduces the pressure of it. Gas and volume pumps can only push through a certain pressure of gas per second. By cooling waste gas, we will allow more waste air to be pushed through the filtering system per second. Extreme heated gas will also be cooled as it comes through, important if there are multiple fires on the station.

    #7 Go to each important accessible room, unlock an air alarm with an ID and change the operating mode to "contaminated". Afterwards, lock the air alarm.

    - Scrubbers by default only send CO2 in a small area back to the waste filtering system. By changing to contaminated mode, it will scrub all kinds of harmful gasses in a larger area. You can also go to scrubber settings and set it all manually, but it takes a lot more clicks.

    #8 Don’t remove custom mix to air output gas pump. Its against the server rules. Besides, its more fun this way.

    - The reason why this is a rule is because its considered metagaming/powergaming. Your character IC doesn't have grounds to suspect the AI/crew will sabotage the air system. Upon actually gaining evidence of a rogue AI, feel free to unwrench this and add manual valves everywhere.
    Many options of the air alarm are confusing or misleading. The wiki doesn't do a great job explaining some things either.

    First off, you need atmosia to be set up properly, or many of the functions will not work optimally. You cant push air into a room if theres no air in the pipes. You also cant suck air out of the room if the pipes are already full. ALWAYS set up atmosia first. Anyway, heres what air alarms do:

    Area atmos alarm:
    Air alarms turn on automatically. The only time you'll use this option is when you want to mess with the CE and atmos techs. You can potentially use it to draw them away from actual breaches, and waste their time.

    Panic syphon:
    Turns on all scrubbers in the room to syphoning, turns off all the vents. Use this when there is a large amount of harmful gas in the air, but make sure to replace the air afterwards.

    Vents control

    Pressure regulator has two settings:
    Internal: Will push air out of the vent until the pressure inside the pipe is at the target pressure you have set
    External: Will check the air outside the pipe, and push out air until it has hit the target pressure you have set

    On/off and target pressure need not be explained

    If you need to refill a room quickly, set the vent to internal and target pressure 0. It will push all of the air out of the pipe. Only leave it on for around five seconds, unless you want to kill people.

    Scrubbers control
    Mode: Can be set to filter or syphon.
    Range: Normal or expanded. Just keep it always on expanded, normal is pointless.
    Filters: By default will only filter Co2. Keep in mind that BZ gas when filtered will go to the mix tank, unless you have set up a canister filter.

    Operating mode

    Filtering: Default setting, takes out Co2 in a small zone. Vents set to 100 external. Mostly useless.
    Contaminated: Sets scrubbers to filter all harmful gasses at an extended range. Should be treated as the better default option.
    Draught: Will syphon in a small area while vents are set to double default output
    Refill: Vents set to triple default output
    Cycle: Panic siphon, but it switches back to filtering when the pressure gets below 5kpa
    Syphon: Syphons gas in a small area. Vents turned off.
    Panic syphon: Syphons gas in an expanded area. Vents turned off.
    Off: (insert witty comment here about how its obvious)

    Filtering, draught, refill, syphon and off are all essentially useless. If you want to argue that off isn't useless, keep in mind you can set a vent or scrubber to filter/vent a tiny amount of gas and the animation for it being turned on will stay the same.

    Alarm thresholds
    Pretty obvious stuff here. There isn't a lot of leniency given, 150kpa is actually safe for people but will set air alarms to red. Sometimes you can change the alarm threshold if theres a room around that pressure and you cant be bothered sitting there syphoning for a few minutes, as it achieves nothing.

    You can also change it entirely so plasma is deemed as safe for plasmaman rooms.
    As AI:

    If the air pipes are full, empty them first by turning off the air to distro pump, and turning on the distro to waste pump. Start filling up the mix tank while you wait for the pipes to empty out.

    Turn on any gas outlet pumps that you want (Connected to yellow piping)

    Turn on gas pump leading to gas mix tank

    Turn off mix to filter pump

    Turn on mix to distro pump

    Turn off waste in pump

    Once you're done, bolt down all atmos airlocks and electrify them. Don't forget to bolt the airlocks in bottom right corner to space as well. Finally, remember that you can close the atmos shutters to prevent any access aside from via maintenance.

    As traitor:

    Basically do the same but you can replace gas pumps with volume pumps. You can also remove waste piping in maint, so gasses will stop being filtered once waste pipes fill up.

    If you don't want to fill up the mix tank, its pretty easy to alter the piping arrangement.

    Other tricks:
    Instead of turning pumps or filters off, set them to 1. It'll still do nothing, but it'll appear to be turned on and working unless people actually take the time to check it.

    Unwrenching waste air pipes will cause scrubbers to only filter gas until the pipes fill up.
    #1 Small amount of harmful gas in the air

    - If you’ve set up atmosia and the air alarms properly, this problem will fix itself. If not, go set those things up instead of grabbing a portable air scrubber.

    #2 Large amount of harmful gas in the air

    Panic syphon the air from the room, refill it with clean air and return scrubbers to contaminated once the harmful gasses are minimised. You don’t need to syphon all of the harmful gas, scrubbers can do the last few percent.

    #3 Entire station is filled with harmful gas, including air pipes

    First up, send all the air in the pipes to the waste system. Make sure the filtering system is actually working. Then its the same deal as before, just you'll have to go room by room. Take all of the portable air scrubbers out of atmosia, and get people to drag them around. Its a waste of time for you to do that yourself usually.

    #4 Malf AI, and borgs wanting to kill everyone

    If you see a borg come into atmos for no apparent reason, run the other direction.

    If you manage to escape, and you are sure there is fuckery about, don't try to re-enter atmosia until after the malf AI and borgs are dealt with. The doors will be electrified, harmful gasses and possible fires will be waiting for you, along with borgs who will go out of their way to make you fail.

    Deal with the fallout once everything is under wraps. Alternatively if things don't get under wraps, use portable air scrubbers, air canisters, internals and welding of vents to keep you and others alive temporarily. Fire suits are essential for longer term survival, as plasma flooding and fires are usually the go-to combination for Malf AI.

    #5 Theres a small fire

    Put it out with an extinguisher, syphon the hot air, replace with room temp air.

    #6 Theres a large fire

    Same as a small fire, just deal with it piece by piece.


    Use a firesuit, backpack extinguisher and internals to put out the fire. Syphon the hot air, replace with cool air.

    Keep in mind that the atmos hardsuit is also heat resistant.

    #8 Theres shadowlings running around maintenance kidnapping people

    Make a ton of flamethrowers with 3000 kpa plasma tanks in them, and start handing them out to security and heads. Go around replacing lights if you need to. Don’t wander into maint without a lot of lights on you, not just PDA light. Use the permafire plasmaman trick to make yourself a walking lantern. If you’re going solo, stick to thin maintenance tunnels to blast them in. Even if you get glared, as long as you get one shot off on them beforehand they will either go down or be extremely hurt.

    You can actually hunt them down by yourself in the correct maint corridors, but leave the task to security instead. Admins generally wont be happy with you making plasma fires that are not absolutely necessary.

    Alternatively, use a backpack plasma tank bomb to deal with the issue remotely.

    #9 Theres gang members/revolutionaries

    Get implanted, then run around with a nitrous oxide flamethrower. Goal is to knock people out with the gas, tie them up, get them implanted. Security hud glasses are a great help when identifying who is implanted and who is not.

    #10 Theres a changeling

    Be ready to use the incinerator if the crematorium mysteriously becomes unusable.

    #11 Theres a hostile wizard

    Be scared of it teleporting into atmos to brutally murder you. Cry because theres not a huge amount you can do.

    #12 Theres a strange man in atmos

    RUN. FUCKING RUN. Call security on them and don’t touch atmos until they are gone. The only reason anyone ever goes to atmospherics is because they are an antag and they want you dead, or they want to mess with Atmosia.
    For clarity, I mean any of the tanks you can hold in your hands. The larger tanks that cannot be carried and only can be dragged are called canisters.

    Step 1: Collect tanks

    You can find these at atmos spawn, in the machine, or use portable ones found in your internals box, in the atmos lockers or at atmos spawn.

    Step 2: Pump a canister full of gas

    If you want a really full canister, place a gas filter that’s filtering into a connect with the canister attached.

    Step 3: Pump gas into an air pump

    Wrench down two connectors with a volume pump inbetween. Turn on the pump. Connect the canister to the side the volume pump is pumping from, connect the air pump to the other.

    Step 4: Pump gas into the gas tanks

    Put a gas tank in the air pump. Set the air pump to max, air in. Turn it on, then switch it off when its done. Take the tank out and repeat for however many tanks you want.

    Optional: Cool the gas first

    If you cool the gas using a freezer before pumping it into gas tanks, you’ll have more moles of gas to work with. This can be great for plasma based uses, but a bit redundant for portable air tanks, as you’re unlikely to run out with an uncooled mix anyway. Even if you do run out, refilling is easy.

    Alternatively, if you just want to fill a tank with air mix, you can use the air pumps/connectors outside atmos. Unfortunately at the moment air mix in internals tanks doesn't seem to work as well as pure oxygen, so its only really useful for pneumatic cannons.
    When I use this, people don’t ask me to stop using a flamethrower. People ask me to stop making plasma fires. I used it one round as a traitor, and afterwards a borg and AI were both checking atmosia to work out how I pumped that much plasma into medbay. Even though I died, that alone made it worth.

    Step 1: Make the flamethrower.

    You can find igniters in tool storage, secure tech storage, or science. You can make metal rods out of the plates that spawn in atmos. Welders are pretty much everywhere, but mainly in tool storage or the lockers in atmos.

    Step 2: Pump a canister with lots of plasma

    Use a gas filter to push obscene amounts of plasma into a connector with a canister attached. Don’t worry, it won’t ever explode.

    Step 3: Make 3000 kpa plasma tanks

    Use the air pump method I explained earlier

    Step 4: Set up flamethrower

    Connect plasma tank to flamethrower. Set output to 1000. It won’t push out more than that at once, so don’t bother setting it to 3000 kpa. Set the flamethrower to "lit". If the welder was low on fuel it might not actually light. Once its lit, it'll stay lit pretty much indefinitely. Chuck it in your bag for now.

    Step 5: Protection is key

    Try to wear a firesuit or atmos hardsuit for flame protection while you’re using this thing. If you stand in the heat for long enough you’ll overheat and die anyway, but at least you don’t have to be too afraid this way.

    Congrats, you’ve made the strongest weapon available to atmospherics. Use it on a private server of yoggstation code so you get an idea of exactly how much fire this makes, just so you don’t mess up on the server too badly.

    Also, keep in mind you can put any gas you want into the flamethrower. Nitrous oxide or BZ are the obvious choices, but theres possibly much better options out there.

    Lastly, I recommend you test this out in a private server or somewhere it won't damage anyone or any equipment. The fire WILL be larger than you are expecting, and you will be forced to run the opposite direction after firing.
    The incinerator is pretty useless. It will generate around 100k-120k power for you. If you’ve played engineer, you’ll know this is really low. On top of that, it’ll burn through all the plasma and oxygen in atmosia in about 20 minutes when its set up properly.

    Unless the engine and two solars have been sabotaged, you won’t ever realistically need the incinerator for power. You CAN however use it as a ghetto toxins lab, or for disposing of bodies. This all being said, it’s a good learning tool for a bunch of different atmospherics mechanics.

    To set it up:

    #1 Replace plasma and oxygen gas pumps with volume pumps.

    #2 Replace the manifold just past the plasma pump with a gas mixer. Set it to max, and set the ratio to a burn mix of 66% plasma / 33% oxygen. (Node 2 will be plasma in this case)

    #3 Replace the mix to mix tank gas pump with a volume pump, and repeat for the mix tank to incinerator gas pump.

    (Optional) Place a line of H/E pipes in space between the mix tank and incinerator walls. This is monstrously more effective than using a freezer.

    #4 Replace all relevant gas pumps in incinerator room to volume pumps

    #5 Open vents in incinerator chamber to remove all normal air, notably the nitrogen. Close the vents after all air has been removed.

    #6 Turn on all volume pumps, turn on the igniter, turn on the turbine at the computer. Monitor charge at SMES, and set up accordingly.

    The incinerator calculates its own power output by the number of moles of gas multiplied by the temperature. We want to cool the gas before it enters the chamber to drive the amount of moles up. It’ll reach insane temperatures regardless once it’s on fire.

    Although, keep in mind you don’t actually have to set gas on fire to generate power. Pump any gas you want into the chamber and you’ll end up with around 55k power charge, based on the amount of moles of gas present.
    Screwdriver an igniter and you can then attach a signaller/mousetrap/proximity sensor/etc to it. You can then attach this to a plasma tank. If that plasma tank is filled to 3000kpa, you can achieve pretty large plasma fires. Or, even better, you stuffed an entire bag with 3000kpa plasma tank bombs. Keep in mind again, you can fill the plasma tanks with any gas you want and it’ll still work, but you’ll need an igniter in the assembly still. Oxygen tanks won’t work for the bombs, it has to be a plasma tank.

    Some practical uses:

    Attach a proximity sensor and signaller together

    Attach igniter/signaller assembly to tanks inside of a bag

    Activate the proxy sensor/signaller, drop the bag on top of it

    Voila, you have a proximity plasma bomb

    Attach igniter/mousetrap combos to the plasma tanks

    Drop them all in a bag, wear it on your back

    Put on a firesuit

    Get caught by security doing something dumb

    Get dragged back to the brig in cuffs, thrown in a cell

    Wait for them to search through your stuff and burn themselves (and probably you too regardless of the firesuit) to death

    Fill mix tank with plasma

    Replace gas pumps down in front of plasma tank and air mix to distro with manual valves

    If anyone asks, claim you’re setting up incinerator

    Attach igniter/signaller combos onto plasma tanks

    Place throughout the station in lockers

    Ignite, claim it’s a rogue AI and that you fixed atmosia so he can’t leak any more plasma (LOLOLOLOL)
    Craftable, requires:

    2x pipe

    8x package wrapping

    4x metal sheets

    One wrench or welder to construct

    At first, this doesn’t seem like a weapon as much as it seems annoying. However, with a few adjustments it’s pretty deadly. Atmos techs have the easiest time out of all of the jobs getting all the parts, and they fit pretty easily in backpacks. If you’re a traitor with a single target, consider using this as a weapon over a flamethrower.


    Use a 3000 kpa oxygen tank

    Wrench it to setting 2

    Add 7 broken glass shards

    A shot of glass shards deals about 75 brute damage, but also will embed three glass shards into the body of your victim and cause them to bleed. You can hold one in each hand and shoot each one extremely quickly if using hotkeys. With this method, you’ll end up doing 150 brute damage in under a second. The only problem of course is if you miss you’re boned, and pneumatic cannons aren’t too conspicuous.

    If you somehow get access to chemistry, make beakers of fluorosulfuric acid and load them into the cannon. This will down anyone in one shot instead, but is hard to actually obtain for an atmos tech.

    If anyone knows atmos, it's cubetastic. Good ol' xenon and other names I haven't internalised. If atmos are doing weird experimental things (like a cooling loop around the ENTIRE station) I always assume it's him, and so far i'm 100% right.

    This is a great guide and I don't see any reason not to approve it. When I get my lazy arse out of bed i'll sort it

    Its a good guide but I liked the old way of just telling people what stuff was and letting them earn the knowledge of plasma flooding on their own.

    Am I wrong to feel this way about teaching people major destruction techniques? Well probably- who knows?

    Only reason plasma flooding is taught here is because it was suggested. Reason being it'll be funny if it ends up getting someone banned for griefing with it.

    Other names I've got saved at the moment are Richard Hall and Joseph Russell. Oh, and I plan to actually finish that cooling loop around entire station to incinerator challenge at some point. It'll probably have to be on a private server though, hard to actually pull off in a single round on the server without help and/or extreme luck.
