How to tackle Slime Biomes : Tutorial nuggets : Oxygen not included 

Back in my day slimelung used to be dangerous

I still thought slimelung would kill your dupes if you wouldnt cure them... didnt knew they changed that...

I saw this hit my feed yesterday and have been excited to watch it. I've got 75 hours played over multiple saves and have never dug out of the starting biome. The advanced mechanics of this game are, to me, pretty daunting. My biggest issue is not knowing what to do, when or in conjunction with what. I love this video as it's short, to the point and walks you through it. Most "tutorials" I have found searching are either old and outdated or they are buried in a 30 minute video (or worse a 4 hour live stream) and you have no idea where to find it and when you do, they typically bounce around multiple times during the process so you never really can follow what the original point was. Kudos to you. I would LOVE to see an entire series of these dealing with the various biomes and then also various advanced mechanics in the game (SPOM, Water Cleaning, Water Cooling/Heating, etc). Anyway, thanks again!

To this point i didnt even know they nerfed it THAT hard. To this point i kept playing around slime lung as it was a nuclear bomb :D I still got huge Vietnam Flashbacks from way back then when Slime Lung entered my base.

Yea thanks to your videos I expand so much faster since slimelung doesnt kill anymore

Love your video's. Would love to see how you tackle the issues in 2022 now that deoderizers require power as well as other challenges in the base game.

Sees thumbnail during first five runs That is a bold statement sir, you should say that to my poor dupes Sees thumbnail during twentieth run Lol man you right

Buddy buds really just rendered slime lung a non threat.

When I started playing this game I was really daunted by the fact that you'd run out of materials because at some point you make polluted water and you have to clean that water or you are losing water and that uses sand and power both of which seemed finite to me but after watching your videos I've realised that while sand is finite it's at the level where you won't run out for a very long time and there is actually an infinite source of water in steam vents. I was also worried that making power from hydrogen by splitting water would result in less power than was used to split the water but that's not the case either although it is in real life. Basically I was worried about mass deleting (sand goes away when you change dirty water into clean water where as it should turn into some sort of mixture of sand + whatever was making the water dirty) and entropy in that you'd run out of resources to create energy but I've come to realise that 1 there is a stupidly large amount of materials and there are also resource taps in the form of vents and space debris so you could use regolith from space instead of sand. Anyway that's just to say I was very wary of this game when I first played it and I always tried to create a very small base when really I should have just watched some videos to understand the mechanics of things rather than assuming they work in a real world way. So thanks

Slimelung used to be super annoying given that you are almost surrounded by slime. But they nerfed it way too much :/ * a nice trick is to plant a buddy bud at at the entrance/exit of the slime biome. Two germs can't occupy the same space so it blocks the slimelung from spreading * I like to place two hand sanitizes there too, so they wash their hands. Yeah, it has to be airborne, but I still don't like them glowing green

Wait until francis hears about the diseases restored mod

Just getting back into the game and I gotta admit, I've been tiptoeing around slime thinking it'd easily wipe out my whole base. Definitely going to expand a lot faster now! Also not sure if it's typically done but I like to dump all my excess CO2 into slime biomes as I dig down, that helps kill off the germs too.

You've been sitting on this one for a little while now. Still think the harder difficulties should add back the more extreme disease effects. Like vomiting for food poisoning, or suffocating in pure oxygen with slimelung, or zombification for the spores

"How to deal with Slimelung:" Deodorizers and pretending it doesn't exist

Wow, so much have changed. I was still under assumption I needed a suit before tearing down a slime area hahaha

Remember when Slime Lung used to be dangerous? Feels like it was ages ago.

There are so many ONI youtubers, yet only this fella give quick (well, as much as possible) concise tutorials about things that stump so many players.

Brand new player here: there really should be better descriptions on the algae terrariums, because it doesn't actually say anywhere that they release polluted oxygen. I only discovered this by trying, because the gas pressure in my base was too high for oxygen diffusers to work properly (which probably means I had enough oxygen already?) Also when did deodorizers start requiring power?

My base, every vertical ladder to go up and down has a fire pole on one side and mesh tile with deodorizer on the other side. Now the DLC requires electricity for deodorizers so best to use a unique electric grid for them as they consume 5w each allowing 200 on normal wires and 400 on conductive wires.

Spamming deodorizers also has a nice side benefit... clay! Later in the game, you'll want lots of it for ceramics. It costs you a little duplicant labor to refill the deodorizers, but it's worth it IMHO.

Thank you so much for this, you've just earned a new Sub! Gonna check out your other vids soon! This might sound odd, but I really appreciate that you talk clearly, succinctly, and fast without being too fast.

Slime lung should be dangerous. Add some thrill to the game.

Now, I make them go into slime biome without atmo suit but they are equip with TONS of sand (and deodorizer)

I never cared about slimeling, if one of my dupes got it I just prevented them from going into carbon dioxide heavy areas/big excavations by removing them from door permissions. That way they couldn't suffocate to death in just 10 seconds with their reduced oxygen capacity/be basically useless since they're always running around for air.

More, I need more! I'm still trying to figure out what to do after the initial biome, once my colony is stable

Ha I'm on cycle 58 and starting to tackle Slime. Great timing!

Wow I’m trying this everybody I’ve seen on RU-vid make this so complicated Thanks man

It would be nice to revisit this one, with the yucky lungs debuff this is no longer accurate. Not that Slimelung is dangerous now, but dupes with yucky lungs use way more oxygen for a bit and that can be risky.

Slime can be converted into water, and food (mushroom farm). It does have some uses. Letting it convert into polluted oxygen also gives you easy polluted oxygen to run through deoderizers. The de-oderizers will give you a lot of clay, which means you have a lot of materials for ceramic, which is the best insulation in the game at the moment. (not sure what they have done with abyssalite)

whenever i encounter something i dont know, i always just do it first to see what happens

I remember when slimeling used to be a death sentence!

I don't know if it helps that much but I think buddy buds can be used kind of like blockades

First time i opened a slime biome, it wiped me. Think it's a bit easy now! haha, I wouldn't have even dared without exosuits until Francis told me to just go for it.

rip old slimelung, I had one or two a cycle contracting slimelung in a current save and since i’d breach the caustic biome a while back and I had enough doctors, it was barely any lost time

Any advice on tackling slime lung from below? The whole top third of my biome has it and I’m afraid of it raining down into my water source all the way at the bottom.

Depends on your game settings. Default settings it's highly survivable. Also, polluted oxygen is awesome...for clay. You need it for ceramics and if I could build every tile with that I would. Unfortunately you run out.

Thank you so much for this. I have been carefully tiptoe-ing around slime biomes, frustrated that I was boxed in and couldn't go anywhere, because I just picked the game back up after a long absence and when I stopped playing slimelung was a terrifying thing that you would never, ever touch because it would end your run in no time and there's nothing you could do to stop it. I'll admit, I'm not sure I like the change. It makes the game feel less lethal. On the other hand, I feel more confident that I can handle it and move forward to something like mid-game.

What to do with de infected slime items?

I know this vid is old. But I really hope they fix this. I play on default settings. And I don't leave my biome until after insulating. And medical room setup. Then build airlock setup with sinks for the purpose of entering swamp biome. Including storage submerged in 3 tiles of water..And setup deodorizers. I have oxygen mask dock on my side of the airlock. Therefore to be completely safe to go in this biome. I don't even go into any other biome until atmo suit. Even though I know it's unnecessary. Something more like this sort of precaution should be default basic settings. In the current design medical stuff and oxygen mask is just meaningless and unused.

slime used to be a real opponent .. they made it a joke.. i dont even bother cleaning it anymore. made the ore scrubber garbage. It used to be deadly

I heard radiation lamps can kill the slimelung before the slime gets digged

Bruh i just so scared of slimelung THAT I FLIPIN RESEARCH ATMO SUIT BEFORE I TOUCHS IT Edit: i got fiber from sand stone near slime lung to make atmo suit

Early game not much but late game stress % going stroink

3 year old video and since I just now started getting into this game I was wondering if the information in this video was still "basically" correct, does anyone know?

I like to make a few storage bins in the remaining water of the first slime biome I excavate set them to only accept slime and put the priority on 9 until they contain all the slime. Because all the slime is localised the dupes sort it out in very short order. Then I destroy the storage again. And for my money the greatest problem (these days) with any kind of gas other than oxygen in your base is that it causes oxygen to disperse more slowly. The oxygen can't disperse as quickly because it has to get around moving squares of the other gas. O2 and CO2 alone are fine, but add a third gas and it becomes extremely chaotic. Just cleaning out polluted oxygen will often cause corners of your base that have lower levels of oxygen to become properly ventilated within a few cycles as long as the CO2 has somewhere to go.

Slimelung can also be dangerous if your base is fairly overrun with CO2 or another unbreathable gas, since dupes can have trouble getting basic tasks (like going to the bathroom) done in the time before their breath runs low and they run off to breath... In some cases this can get them stuck in an infinite loop and they can (ironically) starve to death.

Me playing max difficulty. Respect the slime.

Thanks for the tutorial but i will describe slimelung more like anoying than dangerous.

kinda miss when slimelung could kill your whole colony when there where super dangerous things like that

Is it just me, or do my dig queue symbols disappear after a few minutes after I start a save?

You players shud be way more carefull :) well entire base is green ....... to late for me ...

I wonder how slime lung uses to feel

would you still recommend this method now that deoderizers require power?

Laughs in Rime

This is a bit dated, but I don’t know what you mean by normal and hard difficulty, did they remove hard mode in an update? Because all I see is normal and easy

I remember slimelung being a larger problem... It seems that changed...

Missed the key step of starting from the TOP in my most recent base. My biome is WAY bigger than this one - I'm going to see if I can dig around it up to the top and work my way down again.

i'm starting to think Francis works in real life as an auctioneer

Is this strategy still viable? I'm doing exactly as instructed but the deodorizers are not keeping the slimelung out of the base. Also, slime biome is pure oxygen but the slimelung is not going away.

My Slime biomes are huge, and I'm contained on all 4 sides by them. Any suggestion on clearing those? Because the biome you show seems quite small, allowing all the slime to just fall into polluted water but my biomes are simply too large to do so.

If you don't want to destroy the whole map, you can consider adding a bit of chlorine into your breathable atmosphere, it will kill germs (works for liquid too if you get liquid chlorine)

cheers for the vid Francis.

Has this changed cause My slimelung isnt dying in oxygen

I played oni areally long time ago, when it killed your dupes time, i left it and now im back again and i was scared of slimelung just to find out it was nerfed and it doesnt kill the dupes anymore, im a little dissapointed but its ok

so deodorizers need power now, that sucks....

you forgot to connect these deodorizer with electric wire lol

John, to this day, whenever i play, i never touch the slime until i have atmosuit docks with sinks nearby and chlorine room where i dump all of my slime. am i overkilling this game?

How to deal with the germ on solid slime when picked up to use for mushroom farm? dupe will spread all the germ on ladder.

Wow ive been afraid to do this due to slimelung. I will now conquer slime without fear (or atmo suits)

Just to ask, I have full oxygen (no polluted etc) in my base, and in a little nick I have Slimelung, and it won't ever die in my oxygen, it just keeps regenerating?

Slime with you: DED Slime with me: SPRED

"Slime lung is weak" "Slime lung is ~~weak~~ pathetic"

Hello Francis! Thank you for this fantastic guide. Even though I have been playing this game for years, I actually learned a lot and changed the way I approach a slime biome. I had a couple questions for you. Could you possibly make a guide for people who play the hardest difficulty, especially the part about carrying the slime around to change it into algae. I have had a lot of troubles carrying slimes with dupes because of the thousands of germs they put on themselves requiring them to use 6-7-8 sinks in a row sometimes. I'm not sure if it would be better to use the shipping / convoys system instead? I also run into a lot of troubles with dupes carrying slime, then go do something else ending up contaminating other materials and eventually these materials full of simelung get into the main base and it becomes very tedious doing a lot of reloading of saved games to get it under control. It would be interesting to see how you set your priorities on dupes to make sure that such things do not happen. It would also be interesting to cover the part about slimelung in other gas such as co2 or H2. I have managed to destroy co2 simply by using carbon skimmers but it seems like the polluted water that the carbon skimmer outputs will have slimelung so it's important to make sure to drop it in a polluted water container outside of the main base. Finally, I know that slimelung is not that dangerous but I like to play the game fully immersed. As a result, I consider slimelung a very serious deal and I also try to avoid using mechanics or building/positioning tricks that do not make sense in real life as much as possible. For example, I don't use the salt water tiles to keep gas inside a room. Instead, I build decompression areas.

I still don't trust slimelung. Therefore i usually dig into a pool from up, place a ladder to the bottom, throw some clean water for stop the polluted water from offgassing and then i just dig from the bottom, so the slime falls into the water pool, then my dupes bring the slime into a storage facility placed into a frozen biome with some crude oil placed around the compactors. The slime is stored here, the cold enviroment makes a quick job of the slimelung and boom, free germ-free slime

ah good old days where deoderizers dont need electricity ...;_;

Well, this is a much better approach than the tentative, tepid, single atmo-suit, avoiding slime dots like the plague....approach that I'm taking. But I'm pretty new.

Dump some clean water on that polluted water to cap its p oxygen production, dunk a compactor into that water and sweep the slime into there. That way you don't have to keep running to refill deodorizers and the oxygen will become 100% pure

Ed Byrne plays ONI!?

From the other side of the spectrum, how do you create polluted oxygen on maps without slime biomes. I am having problems getting clay to make ceramics early game.

looking at a tank of polluted water without a layer of water on top is hard to look at

Two germy videos back to back. You beautiful, beautiful creature. Amazing!

Why not inclosing the water to prevent contact with oxygen + putting slime underwater

as always thank for the video :)

very straight forward thanks!

oh... so deodorizer doesn't cost 5 power...

is slimlung more deadly in 2021 than it was when this was posted in 2019 ?

Deodorizes now need power so, it's a bit more complicated. Also side note people, you need multiple sources of power quickly. I ran out of coal around cycle 120, found a natural gas geyser, built a power station but the geyser went dormant very fast after. I'm trying to recover by rushing to another far away geyser, put my food in a ice biome..dupes really don't like hypothermia when they are getting food. . But it's not looking good. My O2 level is dropping and slime lung is getting into my base from the low low pressure. (I even had to switch to alage piles for O2 production... And 8 isn't cutting it. .. Pressure is 800 and falling. And my dupes are insanely stressed out from low morale (trained in things that aren't faves) not enough + to morale.... And the constant slime lung while trying to get to the 2nd geyser and daily hypothermia is stressing then out. ... I'm debating going back to a very old save from the beginning on this map and correcting my errors...... ... But, idk, trying to salvage this sounds like a challenge.

...but how to deal with Slime (for mushrooms) holding a million germs or more?

Does the advice in this video still hold true for current spaced out build?

Can't you use food poisoning oxygen?

not so weak now that you need power to run deodorizer.

Depending upon the map i start a balm lily farm early and create medical packs, combined with a sick bay it solves any slimelung issues. The main problem with slimelung now is that your dupes will drop things and will become rundown and have trouble holding their breath. Its no longer the “oh shit, oh shit” moment and i kind of miss that.

Thanks!

Buddy Buds help as well

Is your voice sped up along with the gameplay?

Best slimelung vid, thanks!

well... I feel stupid

What's the range of the deodorizers?
