Why Oxygen Not Included Is So Awesome 

Thanks so much for taking the time to make this video and for the thoughtful and kind words. Videos like this really mean a lot to the team. This game has become a real journey for us and we love seeing it grow along with everyone's clever bases, strategies and builds. We're really excited for the new wave of regular updates we actually just kicked off the day as this video. Lots of stuff coming to Oxygen Not Included in 2023. Thanks to everyone who's come along for the ride so far

Oni loop: -You go to a certain number of cycles -Realize a mistake you did -Create a new colony -Survive 5 more cycles than the last one -Realize another mistake -Create a new one and survive just a little more. Each time you play you learn a new thing and perfect others. It really is a wonderful game and everyone should try it. Incredible video as always.

My two most favourite disasters were the chlorine gas leak and the steam leak incidents. The chlorine gas leak was quite simple, I had learned that after a full cycle in chlorine gas, all germs died, so I hooked up my toilets to a tank in an isolated room that'd decontaminate the water before taking it further. However, when moving the gas, I accidentally connected the pipes to my main oxygen delivery network without realizing, so when I turned on the chlorine pumps meant to fill the decontamination chamber, I instead flooded my entire base with chlorine gas. Results were not that good. The steam leak incident was pure comedy, I had set up some electrolyzers, and I learned that if you heated up the water beforehand you could get rid of some thermal energy because they always pumped it out at 70°C. HOWEVER, when I pumped the water through the furnace/battery area, it got so hot that the pipes burst and filled the area with steam. Any dupe that went in to try and fix it got scalding burns, and since I hadn't gotten any medical systems set up I couldn't save them and my colony died. Was a lot of fun. Dwarf Fortress style fun.

I love ONI, it's so great watching as my duplicants pee in our drinking, water having to heat up the water to kill the germs, then watching as everyone suffers from heat stroke because of thermal mismanagement, then resetting after realizing you forgot to provide food.

While watching this video, I went from thinking it looked cool, to thinking it sounded cool, to looking at the store page, to placing it in my cart, then purchasing it and at the end of the video it was installed. what a journey. thank you for this experience.

9:13 is just using gas pipe bridges to demonstrate the priority system the game uses for both liquid and gas pipes. If there’s a junction in the pipe, the game splits all inbound packets in the pipe as evenly as it can between the two sides of the junction. If there’s an input node, the game prioritizes sending all packets into the input node, unless the next segment or machine beyond the node is full. If there’s an output node, the game will not send any packets into it. People often use this in ONI to help filter and direct their liquids and gasses in the desired direction without overly complicating the system or adding more power draw to it, and learning the pipe priority system is actually pretty helpful overall. Also my worst incident in the game was forgetting to triple-reinforce a pressurized water storage facility that happened to be set just above my colony’s main living space. It didn’t really kill the base (because it had side-mounted airlocks and the top was sealed), but it was a _pain_ to fix and get cleaned up in time to prevent the entire containment unit from breaking and spilling all 1200+ tons of collected water everywhere.

Honestly; I wish more people were into these types of games, especially ones from Klei, every game they make they put countless hours in and really make it have a personality. It’s a true labour of love and I cannot state enough how much I love Klei. It started out with DST and now it’s a full blown addiction. The way they also interact with the community is great. They’re so hands on. It really feels as per their comment on this like there’s actual people behind the name Klei. Even if my dupes are dying from freezing, my heart will always be warm when playing a game from Klei

My worst disaster was when I wanted to add more water to the tank I had, but I saw the pipes wrong so the water I had as waste had mixed with the water so for several days the water they used to clean themselves was the same as they used to shit

My favourite dupe moments are all the small interactions; can't pick a single moment. If I would have to choose I would say my most mistreated Dupe brought the funniest interactions. It started in a chlorine filled bedroom that is flooded on a timer with flickering lights and ended with them continuously falling through the void of the world in a loop forever. (it was the patrons wish to have the worst treatment possible for their dupe, so I supported them in that endeavour :D)

Oxygen not included is my most played game in steam, over 600 hours and a 2000 cycles colony that I really feel proud of, and even then, im already looking for the next time I hop in since i made so many little mistakes in that colony I just wanna start a new one and do it all over again, just get a good vacation time and you will be countless hours playing this without even realizing it.

Slimelung was a disaster back in the day, we have it pretty easy now. It was the death of many colonies before I figured out how to beat it, then I took a break and when I came back slimelung had been nerfed. Now, much like crucifixion, Slimelung's a doddle. I love this game but honestly the dedication and attention Klei has given ONI is the best value out there. It's changed so dramatically and continues to do so. They have decided to release no additional DLC but rather focus their continued efforts on adding content to the base game for some time. Even if they stopped today it would be incredible but with their stated dedication to free future development it's up there among the greatest games of its kind.

There was this one time where I am so desperate for algae that I had to open up the slime biome where the polluted oxygen is. I made several ways to make it so that polluted oxygen wouldn’t a problem. Then an unlucky thing happened called not having sand which means I could not filter out the polluted oxygen. This made me refocus on it til I realized I am so low in coal and I have no other way to generate power. And then all things broke lose since without power, nothing is possible and everyone got sick and hungry then they starved to death. Nice.

I was into a 1500 cycle spaced out game, and I was a bit careless in choosing too many dupes. I had such a large food backup that I didn't realize until like a hundred cycles later, and then I was like "WHERE IS MY FOOD??" I panicked and had to send over food from another planet while yellow alerting everything to get more food up and running.

Sharing the most amusing way I've lost a colony, now that would be telling. Let's just say that it's usually because you ran out of some resource or other that you thought you had sufficient of and now things just start to spiral out of control as you either try and find more of said resource or try and bring a new system online sooner than you were ready for to replace said resource with something else and now the race is on before you run out of either food or air or both. I can highly recommend this game. It is my most played game on steam at over 1200 hours and to indicate just how hooked I am on this game, my 2nd most played game is under 400 hours.

I was tame the golden volcano. it was vacuum. a duplicant dropped the slime in. The slime emitted polluted oxygen and instantly it was 500 degrees everywhere. -_-

10:00 that’s a really important point with games like these: multiple layers of complexity the player can pick and choose from. I just like to have a colony of happy dupes on the starting easy planetoid, maybe some space stuff, nothing crazy complicated. But other people may want to melt steel or some other craziness.

I loved when i conected all of my base energy suplies and things that needed energy, it's was soo cool see all the wires break down and the oxigen going down :)

Every game Klei makes is incredible, and this game is my favorite. So much thought and love is put into every little detail. Brilliant.

As a mechanical engineer, this is the most engineering game Ive ever played with the simplified thermodynamics that have great implications and the constant small problem solving

I ALWAYS come back to this game every few months. I am rusty, so I lose 3 or 4 times going oh yeah, I forgot about that. Then the 5th or 6th time I finally get back to where I was and am learning something new again. It's super fun. Also, managing a base of toddlers and baby proofing is the best description ever. You have to essentially map out the base and tell them when and how to build it so that they don't: freeze, stress out, burn to death in lava, die to no oxygen, get each other sick which slows down production too much so they die that way too, and so on all while making sure they don't mine the ladders they need to get back out of the water.

I really like this game. But I find it very difficult to learn to optimize stuff, because lots of game rules a really arbitrary and different than what you expect. Like needing multiple rooms/machines/logic for transporting eggs just to keep the numbers of critters in an ranch stable at 8. Or heat energy being randomly generated/deleted in machines, phase transitions or when placing blocks.

i just started going deep in ONI and low and behold you release this video

ONI is my favorite game of all time, and I love seeing people talk about it! Thank you for making this video, I hope it brings new people into the game!

This video is now one of my favorites. No seriously, i love that you explained why my favorite game is so awesome. Rimworld, Factorio and Oxygen Not Included are the best trio possible.

This really is a great game! I appreciate you pointing out that it’s perfectly OK to just casually play as initially I found myself trying to make the “best” everything which quickly became overwhelming. Once I just played for the sake of fun the game really took off for me.

The worst moment is the one where u realise that ur basiclly doomed

Love the video! Glad to see ONI getting the spotlight it deserves As for story time Back when the planet surface was a newly added update, I excitedly started a new colony and immediately built a ladder straight up from my base to space. And I mean STRAIGHT. UP. I had a glossy drecko farm so had plenty of plastic to make those fancy plastic ladders, it boosts movement speed quite a bit. Very nice. Well. back then the meteors used to be quite a bit hotter than they are now. I think now the surface rocks are around 200C. IIRC they used to be.. idk. 800C + WELL. as soon as the very first surface tile was dug up, one of those spicy rocks fell straight down my ladder shaft, melted the entire thing on the way down, landed on my base's door, was too hot to pick up, and before I could make and set up a suit system to grab it some dingleberry dupe opened the door the rock fell into my water supply. Colony's first adventure into space: we saw it. briefly. before everyone died from scalding steam.

9:08this is actually important cuz it shows you the behavor of the game where output

I was not expecting to see the Francis John footage at 7:31, haha. Good stuff

I have to say this game really is a gem. I love how there is dozens of ways to solve any problem. Early game, you have your water sieve to remove polluted water and create usable water. Mid game, you may be able to send it into a steam turbine to turn it into steam, purifying it, then extract the extra water you get from it. Also works for salt water and brine as well. This nets you additional resources and does not cost filtration medium- but takes more time to set up and a bit tricker to make use of. So there is a reason why you'd use either one at any given point. That everything more or less is completely viable. Except chlorine, that has no realistic functional purpose that is uniquely better than anything else. Radiation in the dlc, handles and manages germs better than chlorine ever could. thats really the only balance mistake I've seen.

My favorite ONI moment was definitely when all 3 of my starting dupes somehow built a wall ON TOP OF THEIR HEADS while also digging the tiles under it. It resulted with all 3 dangling with their heads in the wall and their arms and legs flailing around. They died. I started over. I love how all the favorite moments are mostly about when things go wrong. It's incredibly satisfying to have everything going smoothly and when your builds work how you want them to work, but the memorable moments are definitely when everything goes to shit. Honorable mention of favorite moments goes to when one of my dupes starved to death NEXT TO MY FRIDGE because they were ugly crying from stress and wouldn't stop for a moment to eat.

it's always a good day when Robo uploads

This game was one of the first I bought on PC and had a few months of enjoyment but it's been a few years now so I think I'll get back into it:)

The first sentence you said in the video already makes me love you

I remember I played this game like it was my final exam and done alot of of maths and planning. Good times.

i agree, my latest (and most fun) playthrough has consisted of all my bad desiciions leading to a big climax where every single operation started failing, not enough food, oxygen was being replaced with CO2 and hydrogen, and my plumbing and ventalation skills had led to a confusing maze of clean and unclean. So i had to resort to sending the newest duplicant to some rando teleporter i found and start anew on another world....

7:30 My notable incident was deffinitely the first time i became self sustaining, where i was doing so well i played for 2700 cycles without launching a single rocket (in the base game no less, so no neighbouring asteroid for me either) and i brought the hot regolith into my asteroid. 1500 tons of 300C regolith in storage bins heated up my entire strip mined asteroid, which heated up my water supply, which killed my berries, and while i still intend to go back and finish that save, man, i am sad it went down like that.

I've just started the game and it has its charms that make it unique from the regular base management games. It is true that a single faulty bladder could ruin the water supply of the entire base

i remember not knowing how the rad lamps works and accidentally flooding a hall with radiation, whoops.

Sit down to eat, what am I gonna watch now... boom, this video.

I agree totally, I never knew what I was doing until like 100 hours, I have already 997 hours and i still love the game, specially the DLC, I remember my biggest mistake was using jetpacks and atmosuits for the same area, then the dupes would drop the jetpacks in the atmosuit room, then they couldn't go through, my oil pump valve exploded and filled the entire area with natural gas, then spent the next 200 cycles pumping it out :DD

can't wait for the dwarf fortress video

one of my earlier colonies i was digging down and you know how there is a certain range where yo can see well i dug through abbysolite into a volcano chamber with out realizing next thing i know the ladder my miner was standing on melted plunging them into the magma resulting in them boiling alive learnt from that mistake never dig through abbysolite without seeing whats on the other side

9:09 it's not about the gases themselves, rather it is about priority of input-output of gas bridge (and water bridge, they are the same). Normally you use bridge to create a crossing between 2 lines. But since ONI is a pretty wild game, these bridges can be used as splitters and mergers (with added priority system), as shown in the picture. The system is finnicky, you need a constant flow of stuff in some cases, but still pretty useful to have. Also the key to creating self-sustaining base is breaking the laws of thermodynamics - you can destroy heat with aquatuner-steam turbine combo. Devs basically acknowledged that, but without that neat little trick every base eventually succumb to heat death, so they don't touch it

You think a duplicant peeing in your water supply is the worst it can happen? I had a flatulent duplicant somehow bypass an exosuit checkpoint, go into a vacuumed out magma biome that was right next to some very important buildings with zero insulation (relying on the vacuum seal), and just casually farting in there. He burned to death on his own fart and then the next 100 cycles were a mad dash from trying to insulate what is left of my base after the heat transfer burned more than half of that. I learned a very important lesson that day - NEVER pick flatulent dupes on the volcanea map!

My favorite disaster was in early access when a binge eater got so stressed out that she decimated my food supply and caused the entire colony to starve to death because harvest had *just* happened and I was several cycles out from the next yield. That was when I decided that I can accept any stress response except binge eaters and that in general I needed to manage my stress better. The "no sweat" difficulty mode has since made this a general non-issue.

I always restart factorio when I haven't play a save for months lol

This game has been in my whishlist for a while... Thanks to this video I'm gonna buy it right now!

9:13 this is the pipe priority system. You can use this to manage the order of inputs/outputs of a pipe.

Considering how far you made it. I must be extremely smooth brain lol.

ive been playing this since it came out on and off, and i recently got back to playing this again. I started a new world, loaded in and started to build up my base up and was utilzing the little spark slugs to charge my batteries at night. So as i expaned my base i made rooms for the fellas and as i went to the next level up i noticed some neutronium right above the rooms so i thought its probably just a Co2 vent or something no biggy right?? nope as i dug the tiles around it, it turned out to be a volcano that was 20 tiles from the starting spot. So i started analyzing it and 3/4 of the way through during the night it erupted before i could move the rooms and killed all my Little jerry's except for one who was severely burned and died soon after. Awsome Game would rate 10/10! i started 4 new games in 2 days its still just as fun everytime.

Drakensang Online? I remember that game from long ago!

My first colony was about to suffocate to death so I started a second one. Now basically a profesor of applied not suffocating I spammed a shit ton of algea terrariums. They made so much oxygen everyones eardrums bursted.

Greatest thing i've ever played.. over 2000 hours and still nothing comes close to this, still learning new things, i guess i have the slow learner trait. :)

I was an old player before the spaced out update. Was doing initially somewhat well before it came out. Then the base broke. Tbf, I was running low on oxygen and my industrial brick isn’t exactly efficient.

noticed the most replayed section of the video is right after the sponsor talk lol

Had an almost perfect ventilation system set up I had been pumping all the bad stuff to a huge hole I had dug out were I out all the bad stuff I accidentally pumped it into my base filling their sleeping quarters with mainly chlorine gas

I have more than 500 hours on this game and I didn’t touch any of the end game content so far. There is A LOT to learn in this game yet it makes so easy to dive in and so fucking enjoyable the learning process. Probably I spent more than half of that 500 hours in sandbox mode, trying some random stuff and hella enjoying it. I just can’t get enough of this game.

Reminds me a lot of dwarf fortress, but I prefer it over oxygen not included because I think there's more simulation (not only of your play area but the whole world) and I find that interesting in a game. Though with that said I think it's still a nice title. Worth checking out

I ended up creating a problem for myself on my first ever colony. Some background on this, I got the game after getting the dst, dont starve, and oxygen not included bundle on steam. Played the game and immediately got hooked built a lot of stupid stuff on this save. I created what I like to call my potty palace, I created a gigantic area with like 30 upgraded toilets, wash basins, and showers. This put an extreme strain on my resources because of all the piping I needed to do. Ended up screwing the whole piping system up and then polluted my water supply because I pumped my filtered polluted water back into my original water supply leading to tons of problems, but at the same time I was making huge efforts to getting to the surface of my asteroid. It all ended after all most all of my dupes got sick with food poisoning, vomit everywhere (I had like 20 dupes and still was able to feed them all for some reason) at this point I decided it would be a good idea to just send everyone upwards, I then saved and quit the game, never to reload that save again.

I thought the carbon skimmer converts co2 to o2. I have a carbon skimmer in my base that kind of "cleans" the co2 accumulation inside so, to have more o2, i pumped my co2 from the co2 pit into my pit. Not long, my dupes are swimming in co2.

This Reddit diagram you presented shows how do behave gases on different connections. Some of them may be really usefull to simple priorityzation which pipe should be empied first for example when you have two sources of gas and you want one of them to be drained faster. The same way it works with liquids.

I had very much problems with energy in midgame untill I solved this problem with fast ranching as much stone hatches as possible to get more coal than I require.

i was trying to yet steam into space to get rid of themperature, bad for me because i used heavy wire trught the wall and now my base its a a healty 90 degrees :)

You should really try Sheltered. Its a great colony management story generator survival game that's super addicting!

Well, in my latest playthrough, I was making plastics, or at least, that was the plan. The petroleum was sent through a metal refinery making steel first, which heated up the petroleum to some 200+ degrees. I figured the heat would be more manageable once it was made into plastics. I leave it to do something else, and only return after, what, 50 days? There's little plastic, but seems to be an oil spill on the ground. I send someone to mop it up, and don't think much of it. 100 days later, I finally realize that it's not an oil spill, it's naphta, which is what you get when your plastic melts. Turns out, plastic has a melting point of 159 degrees. I used all the naptha to make liquid airlocks. It has no advantages over simply using crude oil, BUT NOW I HAD NAPHTA, AREN'T I JUST LUCKY.

Nisbet. I got my 5 year old niece into this game (she’s a big fan of the outhouses). Wanted to play every day. Wanted to see how they were doing. Wanted more toilets. Then came the day we got an alert, and found Nisbet’s body at the bottom of the reservoir. We had to take a break from gaming for a while after that. She plays again, now. And her #1 priority is making sure any body of liquid has a ladder.

I'm going insane from playing this game yet I still love it, I can't stop

One time my dupe got to space to get a small piece of meat to put on the fridge and a meteor hit him exactly when i was gone to drink water in real life, then i learned to pause and save constantly x=x

I miss the minecraft series back to basics,that’s how i discovered your channel

My favourite disaster has to be, when the dupes build a wall and end up on the wrong side of it, or they dig out the piece of earth they happen to be standing on then plunge down into the magma, I just love those moments, don't you?

Will you play Dwarf Fortress?

Owhh dude. This is my favorite game ever

none of my friends are brave enough to play it, but love watching me play it. They can't believe all the problems I have with pee water and hot air and poop dirt

I came to have some I sight into the game as I havent played much already and then I see its sponsored by a game I completely forgot about and used to love as a kid 😂

in my first spaced out mission I sent a dublicant to the surface of the nearest asteroid, only to realise that there is no oxygen on the surface (obviously....) and he suffocated to death.

My favorite moment was when I built some basic (and I mean *really* basic, how much can you cram into 10-15 days?) base, didn't like how it all looks like and realized couple mistakes. Then my OCD started kicking in and I wanted to start from scratch, and I don't remember why exactly but instead of doing that I just left the game open and running for a while. What I didn't realize, and what then made all my subsequent plays way more relaxed and chill is how resilient your duplicants actually are. With a barebones almost non-existing base those little shits went on to live for 150 more days WITHOUT ANY INPUT AT ALL FROM ME.

The "Starve" caught me off guard

my favorite moment was when I dug out a volcano above my base without noticing and it killing everyone.

So you never really have a moment of calm, you're always on your toes?

I once accidentally poured my entire salt water storage onto the magma biome and had to spend about 400 cycles to cool all the steam down.

When on the badlands my dupe ran into an only carbon dioxide area and nearly suffocated because I forgot about them!

There's one time that I found an air vent, and I was like 'yo, cool. infinite water'. but then my colony went hot. machine starting to breakdown, and boom dupes die tryna fix it and passed out. After that it all went down to hell, and I have to restart. fun tho! Now I know I have to be careful with temp too.

Once when I was planning oni i try make oxygen farm you probably know what I mean this one with convert water to oxygen and hydrogen and you use hydrogen to pover the farm and I was wondering why it doesn't work and then I realised that duplicant didn't set mechanical filter becose I didn't make path

image at 9:15 from reddit, is visual representation how can one use gas bridge to direct gas or prioritize flow through gas pipes

What's the game being shown at 8:08?

Excellent and accessible review. Well written. Speaking voice stradles the average person and the well-rehearsed but not too polished professional (plastic) voice.

Worst disaster was moving the Spom to a better location, cuz heat and cooling... just didn't realize it had 250kg of oxygen per tile ...

what I love restarting in factorio

you cant get enough with this game

My favorite dupe moment is when they have break, give each other balloons and after break with balloons 3 of my ranchers go hug incubators at the same time. It looks so cute! Specially when one of them is a yodeler ❤ it looks like they visit eggs to hug, sing and give away balloons for baby critters ❤ The disaster I had back in the day when I was starting the game was by accident opening up the space and all oxygen got shot out from my base and before I could fix my mistake everyone sufficated 😂 Also back in the day dying was much easier because dupes were more stupid 😂 my casual deaths causing my countless of resets: pissing, slime lung, scalding 😅

Honestly, the only other game I've played that comes close in systems complexity is Stormworks. I love it. I really enjoy the electric and fluid mechanics. That said, I still don't understand how you get into space and all that without having a solid grasp on the details. It is a looooong game. But it's very rewarding and addictive.

Once I've created 10 electrolyzers worth of oxygen production in the middle game, that was horrible mistake that cost me water, power and space for pipes, and at the end I had too much oxygen and everything stopped working with 20kg of atmosphere per tile in my base 😎👍

critical failure2: 1. Routed high-wattage cable through the base not knowing it has a major impact on the decor. 2. a dupe died or 2 or 3 and i didn't notice until 10cycle later (check and number the beds, if they don't come back, they are stuck) 3. a overstress dupe destroyed the main water tank drenching the entire base. (Don't put the Main water tank In the middle of the base) 4. Trying to supply oxygen to the entire map!? ( only supply the base and seal it up tight) 5. trying a fill a vertical stable with chlorine is a nightmare. cannot be done- overpressure)....( just letting the air column settle down and surround the chlorine layer with a room is so much easier. Horizontally) 6. Base overrun with germs! thinking i can Tank the virus ( wear an oxygen mask and use checkpoints) 7. Run out of coal and gas, ......... cannot do shit. gas gazer will not emit gas for another 100 cycles!. 8. classic, starve to death, Good food farming is so freaking hard. 9 put the refine metal pounder on infinite, not knowing it is at 50%! ran out of metal (just make what you need!) 10. wasted days trying to get smooth hatch only to not need them. other lessons: - you don't need all 4 walls, use the natural tiles - when strip mining you don't put up the ladder on every tile, use alternates, they can JUMP, - you don't even need a ladder just don't dig the natural tile - make use of gravity. collect only at the bottom - use material already nearby. - when dealing with airborne germs, use the deodoriser, be liberal. they are freaking cheap. like whole freaking rows of them. making airflow tile to let the oxy pass.

my biggest mistake was messing up the air causing the whole base to heat up like crazy and having no breathable air

ONI is really flexible, I can't even think about using molten steel , magma as coolant for metal refinery 🤣，I can heat the the magma to melt regnloth.

You should try reviewi9ng DFwarf Fortress! Its like the game which started the whole colony simulator genre
