Critter Tier List - Oxygen Not Included 

I would personally put glossy dreckos in S They are absolute MVPs of critters if you don't have oil on your starter or tp-connected planetoid, and even when you do have oil, they give you access to plastic with such minimal effort, in my experience I usually end up just putting minimal ranch with few of them feeding off wild-planted mealwoods and a starvation-sheering chamber and just forget about plastic forever.

The tier list is pretty acurate when speacking purly about tamed critters, but you dont have to tame critter to make use of them. Pockshels are an s teir for me, because i treat them like a trash cane. If i have p-dirt i throw it to them and get some sand from a reasurce i otherwise have no use for, if i dont have p-dirt they just starve, and since i dont tame them they wont actually die from starvation. If you put them in your water souce they turn to the sunny veriant and help to clean up whatever "insidents" that contaminate in your drinking water, if you put them in other liquid than you just get some lime on the side. Very useful

Sad to see dense pufts in D-tier, love them in my gold-deficient cluster.

I absolutely adore slickers not only for their diet and produce but I just find them absolutely adorable including the long hair slicksters despite them being a waste of oxygen

I'd argue glossy are S tier, since in spaced out is not always easy to get oil early on

I think I'd sort a few of them differently, but then that's largely because I tend to spent an inordinate amount of time in the early and mid-game phases. So things like smooth hatches and glossy drekkos are valuable to me since I don't tend to get to industrial cooling until later, and they're a very heat-efficient and accessible way of getting refined metal and plastic.

I've never used a Polymer Press. In fact, in my current playthrough I'm on cycle 700 and still didn't extract any oil so for me Glossys are S tier

I like to use a wild smog slug to pull the CO2 and other gases out of my main base areas. As with a lot of critters, they don't have to be tamed to be useful. Smog slugs like to travel to the unbreathable gasses on their own, so I don't have to put up any automation or filters to put the Oxygen back into the livable space, or lay my base out in a very specific way to get the CO2 to fall into the correct position. So they basically end up being a Carbon Skimmer that costs nothing to maintain, and puts the CO2 onto a piped output instead of deleting it. perhaps the only downside to this is that they don't sort out other unbreathable gases themselves but I'd have had to filter between them if I was using a pump anyway.

with beetas you can make not only enriched uranium but also good hydrogen farms (saturn critter trap)

Shine Bugs are better wild than domesticated as a free light source. Do you want to make your dupes eat, use toilets, cook food, or work 15% faster? Put a wild Shine Bug there. XD As a person with over 1000 kg of excess oxygen every single game that has no need for more than five tiles of oil - Longhair Slicksters are a source of meat and eggs that don't need their food transported. As for Pokeshells, you never run out of polluted dirt with the stable Pacu aquarium. And you can use Pokeshells to "evolve" Pacus for you. XD

On some maps dreckos can be the only access to their respective ressource. Also, the only renewable source of lime being 'worse' than the decor bugs really hurts!

Note: Sweetles have a very quick reproduction and can lay Grubgrub eggs, which drop 4800kcal on death, so 1.5 BBQ. This means they are actually very meat efficient if you can find a setup to both have enough sweetles in a ranch that then lay grubgrub eggs to be evolved.

I'll usually keep a couple Smooth Hatches around if I get them in the early game. Gold Amalgam is replenished through meteors, and gold is incredibly useful for radiant pipes. You also get less of an energy refund from refineries processing gold. I never try to breed them though: the amount of ore you would waste trying to get an egg intentionally far outweighs any value they provide. Gold or copper volcanos render them obsolete, of course.

Since I like to play forest asteroids, going the ethanol route, I'm a big fan of the pip+drecko+pokeshell combo. And I often find the extra lime from pokeshells, whether wild or ranched, to be quite useful when mass producing steel (especially in base game, when bunkering the space biome, and for games where gold amalgam isn't present, so more steel is needed). Later, oakshells and slicksters can help increase the efficiency of ethanol power, turning the waste products into more fuel, so those are also in my A tier. And then I would put all pufts in my B tier, as a ranch that handles all the puft morphs makes a bunch of different resources renewable in one go. Sure, you can build oxylite refineries, and now also bleachstone hoppers, and you can get slime/algi from space, but a puft ranch covers all of that while being arguably more interesting to set up, and more fun to optimize/tweak/automate. Whereas the machines are kinda boring in comparison.

I agree that longhair slicksters are intended to be a punishment morph, BUT I'm curious about the water to calorie comparison of them versus plants like bristle blossoms.

Shinebugs are very useful for Bristle Berry farm, it is a heat-free light source and Bristle Blossoms are sensitive to heat. The small amount of radiation can slightly increase the chance of obtaining mutated seeds which is a minor but nice bonus.

I feel like the slug morphs are basically one little tweak away from being useful, since they're... well, honestly pretty neat? I really like the idea of smog slugs acting as a sort of filter for all those unbreathable gasses that might be floating around your base, it's just strange that they don't really... do... anything apart from that, giving them a reason why you'd want to feed and groom them. Looking at the plug slug, which emits more power when fed... why don't the smogs scale up too? As a example, they could duplicate the gas that they're holding if they're fed. Which would give them a nice niche living in the ceiling of a plug slug ranch, sucking up all the hydrogen the slugs are farting and duplicating it for extra power, at the expense of the food you're feeding them. (Also smog slugs should totally excrete their own hydrogen into their pipe at night, IMO.) The same could be used for the sponge slug, which could be useful on a metal-heavy world that's low on liquid.

I like Longhair Slickster. When the electrolyzers are up and running non-stop, oxygen no longer a problem. I keep a few wild Longhair Slicksters inside bedrooms. I think Longhair Slickster goes matches the Carpeted Tile, they both fluffy and comfy.

14:35 Smog slugs can be used as ghetto CO2 pumps inside rockets for long journeys, making a storage bin of oxylite inside (for offgassing) and a smog slug (to suck up CO2) a viable option. You can, on top of that, add a sleeping location for the smog slug to expel CO2 into space or storage. However, I admit, that is definitely a niche use and only lasts for maybe 70-100 cycles before they start dropping plug slug eggs and the farm falls apart, needing replacement. That said, for semi-long journeys, they're a neat option.

Very interesting video. Always interesting to see where seasoned ONI players rank things.

Fun video. Only thing I would change is the Delecta Vole as it only drops half the meat compared with the default morph (8,000kcal vs 16,000kcal).

Thanks for doing what you do!!!

This is a very good ranking list, GCFungus does have the best oni takes. The only reason I want to farm slickers is because they are cute.

Your OWNI journey? Your own ONI journey, get it? . . . I'll see myself out 😉

Very insightful tierlist

4:50 The only great use for Shine Bugs in SO is either in a shine bug reactor for power or radbolts, which is hell on your performance (and much more performance-friendly methods exist) or as plant mutation, where an egg-dropper starvation ranch of shine bugs is the easiest method of flooding a few plants with rads enough to guarantee high rates of mutation. Outside of that, they're just a menace on your performance.

Gulp fish can be free heat deletion water purifier. In My current playthrough, gulp fish delete all heat from metal refinery which run with pwater. Gulp fish can turn 90C pwater to -10C ice.

I would personally put the default shinebug slightly higher as the radiation can kill germs rather quickly. They also provide a free light source for stations in the early game when you don't want to spend power/heat on lighting fixtures. Putting a wild shinebug in the polluted water tank, research areas, certain farms, or in a room where you store germy materials temporarily really helps things for basically free (so long as they are wild). They certainly deserve being above morbs. Otherwise, great stuff!

My opinion is that with packed snacks disabling the infinite pacu starvation cell, and quartering the amount of algea that Pacu need to eat, feeding is now much more space efficient and pleasant than starvation ranching, even when you account for needing additional farms to feed them. Therefore, Puft ranching is now more desirable than ever. When you can ranch them for only a paltry 18 and 1/3 kilograms of polluted water per puft per day, and one puft feeding over two pacu, i think it's pretty reasonable.

I LOVE how everyone is giving better and better notes to the vídeo. I prefer to prioritize critters and plants because they usually avoid excess heat from machines, which for me is a big deal: purely on that reason, pufts and smooth hatches would increase to the next tier at least, and glossy dreckos are by far my favorite critter, because of heat-free plastic, even more than slickters, and with pips they can easily be feeded mealwood, so S+ for me. Shine and Sun Bugs are useful for Energy free bristle blossom Farm, but beyond that and duplicant Stations boosted by light, i can't see the benefits of ranching them (decor can be handled easier i think). So all other bug morphs would Go down to D. My last opinion is that i avoid tropical frys but man i love gulp fries, my little water-cleaning critters, they should be buffed a bit in that role. Overall i agree with the list (yes, i'd love me little crabs to be higher)

IMHO glossy might be as well as going for the S-tier due to how quick they let you access to plastic, which means allowing building of steam turbine before even reaching the processing of oil at all, meaning earlier taming of hotter geysers such as the steam vents, etc., so lowering the total chase for oil depth to get crude oil just to get plastics. Combining the ranch between mealwood and wheezewort allows for even mutant seeds to be used, which one could reduce the dirt needed. Also for hatches, even if you don't have volcano for renewable igneous rock, or for other reason, as long as you have the ancient specimen story, you can source renewables sedimentary rocks from fossil, along with limes, while feeding the hatches sedimentary yields a positive coal value (diamond->fossils->sedimentary rock+lime->coal->refined coal->diamond), iirc 1kg of diamond can be recycled back to 38kg of diamond (if decide to complete the cycle), and considering how much diamond people can get from oil biome, it'll be hundreds of cycle before needing to worry of running out of diamond, unless active use of drillcone and such, but even then, still a ton to make, and radbolts for diamond press can still quite easily made with the nuclear reactor once you reach that far, but at that point it's hardly needed, or just using wheezewort farm with radbolt generator to generate the radbolts at midgame. Also bit difference: stone hatch can eat igneous rock, while normal hatch can't.

Smooth hatches are actually fairly good on warm swamp-less asteroids. They will let you build up iron for steel making without the heat issues of the forge. You don't plan on keeping them forever, obviously, but they can drastically help a heat budget until you can set up a cold generator of some kind

Mostly agree except for slicksters. They yield so little oil/petrol that it's just not worth it vs. oil well. CO2 is useful for producing extra polluted water for thimble reeds via carbon skimmer. Otherwise CO2 can just be vented to space. Minor nit-pick on stone hatches. I would actually put these at S-tier because most maps have such huge quantities of raw minerals you can go thousands of cycles before even worrying about finding a sustainable source.

I wouldn’t change anything in that line but the plug slug is a tier for me because I’ve got 12 of them running my whole base and it’s still going strong at 620 cycles 😄👍

There are many "niche" situations where a critter that woukd otherwise be C tier could be effectively B tier, and likewise some situations where a D tier could leap up to B tier. But this is a general "all factors being equal" baseline to measure by. I like to know the viewpoints and uses other people have for them, because, for example, at one time I had so much trouble keeping slicksters alive that I just couldn't. I've seen people point out how many slicksters you need to make an appreciable amount of oil. I frequently find pumping carbon dioxide through a heavy heat area (mostly to heat the gas, not so much for cooling) then dumping it into a chamber with a few slicksters over mesh tiles with a pump way below "happens to provide some oil" while eliminating the need to pump the carbon dioxide to space or using carbon skimmers or algae terrariums.

Speaking of the longhair slicksters, if you have too much oxygen and you have electrolyzer-based SPOM, you could've fed the SPOM less water, so it's a choice between whether you want to turn water into barbeque or another food that takes water to produce.

The shell group work great if left wild. Unlimited food, lime and wood just toss them extra food to increase population but dont close their areas in.

In my experience it is entirely unnecessary to feed cuddle pips anything other than arbor trees. They produce more than enough cuddle pip eggs to supply a ranch and you can fit 16 of them in a single ranch. Because of this I think they are actually a tier above the pip.

if you make use of exuberant mutant seeds all of the pokeshell mutants become much more useful as they can eat the rot piles produced and by recycling lumber for oakshells you can also produce large amounts of water through this

I would absolutely love a plant tier list, I'm conflicted about which ones to focus on

ty very much for all yours videos c:

Longhair slicksters are secretly great. Water sources are usually more abundant than magma volcanos, so they’re more sustainable than hatches later in game.

I've not tried it yet, but I wonder if sponge slugs would pair nicely with slicksters...

A bit rough on sanishell. Polluted dirt is not that hard to come by. Slime can come from meteors. And otherwise easy to ranch and provide food for burgers. Just a few is needed

Dense and Squeeky Pufts are actually super easy to ranch. You pretty much just stuff them in a room and pump in whatever atmosphere they want. The only management you have to do is to get rid of the occasional puft egg which you can just set as a repeating task on an egg cracker if you don't want to ranch pufts separately.. They'll breed princes as needed on their own. Of course you need a good source of surplus oxygen or chlorine.

I usually release carbon dioxide into space, to me slicksters are C tier. Moving carbon dioxide to ranches and petroleum back to power plants also requires electricity. If you consider this and that, you will lose electricity overall and require additional manpower. If the temperature is not maintained at 100 degrees, crude oil is produced instead of petroleum, so there must also be a means to raise the temperature of the ranch.

I fell into the smooth hatches trap once. I basically fed them all my ores, later I found metal volcanos. I had no metal ores anymore - the only way to get them was by space mining. Oh boy was that a pain. I had to deconstruct all kinds of stuff to get metal ores, even converted stuff to steel just to get metal ore. I see you put cuddle pips on S tier - they can also wild plant? I didn't know that. I generally just kill them.

Long hair slickster are S tier. They consume all the waste oxygen from my hydrogen rockets and turn it into meat.

14:38 some guy on reddit did a no power base i guess that is the only reason to use theses guys. also beetas also can be used to farm saturn critter traps giving them another use

1. Grubgrubs/swetles. For the efficiency reason they both been farmed simultaniously for smooth "sulfur -> sucrose -> mud" transition route, as ranching grubgrubs alone directly on sulfur is strictly inefficient. Still, I agree, niche use for "I have a sulfur geyser here" planet. 2. Longhair slicksters. I have an idea of a closed system based on _morb_ ranching, which could supply dupes with food and oxygen with literally no material input whatsoever on a very short production cycle (morbs -> P.Oxygen -> freezer -> oxygen -> slicksters -> meat). Probably, in vacumed "minimal feeding" chamber/farm. But still, I agree with that D tier of yours, as it's, deffinitely, not a "I do that way every time" scenario.

Smooth hatches are fully sustainable late game if you take into account space POIs. Not that I'd advice to ranch them.

There are some that I would clasify as "punishment" for not doing it right. >Accidentally left all the plugslugs in hydrogen/water? Boom, sponge/smog slugs!! >Bringing slicksters into normal temperature room? Boom, longhair slicksters!! Etc etc, this also includes shove voles and the delectavoles if they're fed the ultra hot regolith straight from meteor showers. Meanwhile Pakus are the opposite, they kind of "adapt" without becoming an inconvenience later on. And btw, the Morb is amazing, for example, having a lot of them in the regolith asteroid where there is NOTHING THERE, and a sustainable source of oxygen is almost mandatory, (or keep launching 200kg packages of o2 from the main planetoid as I'm currently doing) and it doesn't lag that much as the map itself is small. Why am I in the trashy regolith asteroid you say? By accidentally almost asfixiating my pilot in his rocket and emergency landing... (he survived btw)

I'd up the ranking for pokeshells. I'm running a p-water refinery by boiling it, and the little bit of pdirt seems to be fine for my wild pokes. Haven't had a single lime shortage in probably 400 cycles and I'm going steel crazy. Granted, they're all wild, not sure if my pdirt supply would keep up.

I use abyss bug for my rad bolt reactors for all of my colonies because 1. they live for 75 cycles, 2. Eat abysalite which there is hardly any use. Take up almost no space. i can get up to 4000 rads or more per reactor! . very compact design. my only problem is getting them to lay eggs is pain in the ass. The work around is the Azure bug which produce abys eggs in large quantities if you feed them refine phosphorus. which is easy as pie to make in large quantity if you know how to heat up and cool stuff. The Main problem with Azure bug is it live for only 25 cycle and if you only feed it refine phosporus, it would ONLY make abys egg and NOT Azure egg. meaning your Azure farm will die out if you are not careful. to get them to make azure egg. azure bug need to eat Stuff berries, which is another pain if you are making berry sludge at the same time. but this is extremely sustainable because i don't use ANY limited radio source and i can place my reactor anywhere. abyss bug = S tier

i would think more on smooth hatch, they are less efficient than refinery, but they don't produce so much heat and i always have problem with disposing heat in early game, for me, smoot hatch is very good early and mid game, late game where heat is converted into energy it will loose purpose

Having played a decent bit of hours of the game and someone who loves ranching 1. Hot take: Grubgrubs are s tier they are excellent for domesticate and wild farming im surprised you aint put them in S when you promote wild farming. They basically make it so you need less plants and resources to grow them and all you need to do is tame a sulfur geyser. 2. I believe you overrate slickters ive tried them and honestly like them but they dont produce enough to rank them so highly i would put them in B tier. 3. Pokeshells and its morfs are what i like to call situational critters. A critter that is only useful if you are going a certain route. If you are going the arbor tree route for power like im doing in my current playthrough then they have a use especially oakshells. I would put pokeshells in a tier of itself being situational. 4. Glossy dreckos should be in S, with spacedout mode without mods you start with no oil. So they are great early plastic and meat, they produce a lot of plastic overtime. 5. Beetas should be in the same tier as pokeshells as situational since they are only useful if you plan to use the reactor besides that they are nothing. 6. Stone hatch should be in s tier for ez food and coal. 7. Morb in c tier mot that useful to be in b. Besides these i agree with your list.

I've been doing some calculations on Sage Hatch ranching with a Lettuce farm. Amazing coal output. Worth looking into.

I think plug slugs could be quite good now too but i havent played in a while. They are very powerful early and now you can feed them with refined metal you can squeeze quite some power out of them. the mutations are so annoying thought cant liquid lock them in a room any more...

Smog slugs are sometimes used in rockets to clean up carbon dioxide

Jesus , Beetas yet not mention its broken combo with Saturn plant for free Hydrogen and power ???? I would put it in S tier instantly .

Glossy dreckos with the mealwood on pot "feature" are decent

I would definitely put plastic dreckos in S tier, for sure above regular dreckos, also I would drob down delecta vole to C or even D tier (because they give much less meat than regular shove vole), also change the order of hatches, because I consider sage hatches being the best one, because they give 100% output, like none other morphs, and they can eat polluted dirt which is easily renewable and widely available. Also I would put the gulp fish in first place between other pacu morphs, because they are just the same plus they clean water. And probably get the dense puft and longhair slicksters up to C tier, because they are not that bad.

how do i produce sulfur with acid gas? have any tutorial? i like ONI, but is so difficult find youtubers in br playing it, i like so much the channel.

I think I've only got two differences. Both drecko's belong in S tier. With a single mealwood ranch farming both and overflow room, you can get tons of plastic and plentiful reed fiber for no heat. Yes, it doesn't last without dirt, but it's a simple 1.5 room ranch that requires no tech and low power to turn dirt into food and useful resources. Pokeshells (base) belong in B, maybe A tier for producing lime. Once again, turning low-value polluted dirt and rot piles into a more useful resource. Admittedly, I only use a ranch with 2-3 and combine it with an overflow pit. They definitely aren't S, but I never regret ranching them.

Will there be a video for the new pacu farm?

I'd put all the shine bugs in D. Cause they make the game lagging.

I think there should be a new hatch variant that goes through the sage hatch stage. Perhaps the new one can eat most organics and produces fertilizer.

Will you update the critters tutorial bites post the last changes?

I really think g.drecko should be s as well because I just ranch dreckos usually with all feeding only with mealwood yes even normal ones its really easy to use pip ranch to get dirt or just use composter but theres a cach here im only doing 1 full ranch of normal dreckos and 5 g.dreckos whithout an evolution chamber I just dump the eggs in a hydrogen room whenever they hatch They get sheared there and I make so much plastic im using plastic over mineral whenever I can 1 ranch of normals are good enaugh to keep fiber coming and theres no need for chlorine to ranch them this way since they will have eggs even if they eat mealwood 6 total farms just keeps laying enaugh normal ones therefore I dont use atmosuit for ranchs just for evo chamber which saves a lot of time and effort

the critters i am using are 1 deckos most for reed fiber midgame and phosporite lategame 2 stone hatches if you have volcanoes or a regolith melter for diamond. 3 sweetles + grubs for farming boost on mutated crops if i can be bothered 5 pips if i expediently killed of to many wild pips.... 6 shove voles if i run bbq After many thousands of cycles I came to the conclusion that sliksters are not worth it for meat production. They just cant beat the shove vole and their byproducts are kind of redundant. You usually run sliksters when you have lots of oil vents floating around any way and that makes em useless late game. For example if you want to feed the resin tree with frost burgers or even bbq you need more than 120 slicksters....sorry cant find exact number any more... . They are great for efficiency on paper but in reality they are not worth the fps loss.

Thankk youu 🎉

So pokeshells in C tier what is this heresy the lime producing god machines as they are. even if you just have one and yeet it in with the water purifier free lime for life and it takes care of the polluted dirt and gives you sand which is yeeted back into the purifier just a great combo.

The biggest disagreement I have is with regular puft. If you don't try to go for dense and squicky, they aren't that hard to ranch. The reason why they are great is because they are the easiest way to get renewable slime which is necessary to sustainably grow mushroom, which is then used to produce quiche, one of the best foods in the game. Also pacus are still S tier imho. Starvation ranching hasn't been their best use since the introduction of quiches at least. You can feed them with excess seeds and get lots and lots of eggs from them, one egg every 1.5 cycles. Each pacu egg weight x2 the normal size, so you can actually make 2 quiches per egg.

i will have to dissagree with you about smog slugs. because they only take in unbreathable gases, they are the perfect sollution for that little bit on natural gas or chlorine that likes to gather arround the bottom of my base because i reckelssly dug a bunch of bleech stone, which i think should put them above the pufts. but yeah other than that i dont think theyre much usefull

I'd have put beetas in S tier, because if you're running a nuclear reactor (which I think is a very reasonable thing for players to do) then they're not just nice to have or useful, they're essential. Trying to obtain fuel for your reactors without them is so incredibly wasteful that I wouldn't turn on a reactor until I had a beeta ranch going, unless I was truly desperate for power. Other than that, I broadly agree. I tend to leave my pips wild for wild planting and not tame them, but I think I'll try them on my next play through.

Guessing all variants of Pacu have changed as about two days ago. Cann't you use the Shine Bugs for Radiation.

i disagree with some of the things here, mainly things at the bottom of the list, here is why: 1. smooth hatches have value in a few ways, for one it saves power since the rock crusher and metal refinery take quite a bit of power. running complex industrial bricks can recover some of it, but they are undesirable due to the resource and area demand. secondly, the smooth hatch switches the burden from operators to ranchers, which are always more in number due to BBQ, coal, and drecko ranching that colonies typically need, reducing the need for extra operators and buildings, and finally there is no heat penalty associated with them. 2. longhair slicksters are among the best in this game, due to the lack of need for complex systems, unlike the other versions which require annoying industrial bricks that are meme-ish with any normal build. furthermore, they consume only oxygen, which is easy to get in the modern game, and gives food longevity that only pips with wild arbors and dreckos with wild planted crops can share, all while consuming the same resource shared with dupes. that is not a handicap, but a blessing. 3. the pufts get low grades, but only one full stable of 6 standard pufts can support at least 40 dupes with fried mushrooms, provided that the dusk caps have micronutrient applied ( i still fail to understand why people ignore this anyway, duration scales based on dupe ag level by 10% per level, and it works on wild plants.). this is not hard to build early since polluted water, used for the polluted oxygen, can be provided from lavatories and showers. puft princes can be in the colony itself, due to the oxygen consumption ability. 4. as for the squeaky puft and dense pufts, there is no need to pair princes with these. the reason for this is that a standard puft with a prince will 3 way split 48/2/48 between squeaky, puft prince, and dense puft respectively. every puft that is thrown into a large overflow room with princes, or a stable with princes will either lay dense or squeaky eggs. there is no need for complex ranching of them. if it makes things easier, throw all of the dense puft eggs into the main colony area, and let them float around, only picking up the oxylite they drop around and storing it in containers. since metabolism is -80%, then you will need 30 non groomed dense pufts to equal a single stable, this is not hard to reach, since a groomed puft of any variant drops an egg every 4.5 cycles. 5. large scale wild planting arbors for pokeshells is quite unimportant, since the ethanol produced will be used to generate power, which produces polluted water which feeds the majority of the trees, 6.4 arbor trees to be exact. one only needs 4 wild trees to equal 1 domestic, so 6 domestic trees with 8 wild trees will support 4 ethanol distillers. this supports 1333.3 grams per second, or 799.99 kg of polluted dirt per cycle, enough for 11 of any pokeshell variant. 6. as for the two slug variants, i haven't used them so i don't have any numbers, but i will say this, they don't require plastic, they don't require power, and they don't count as industrial equipment, holding back room formation.

You do realise Plug slugs produce 1600 Kw/s when ranched, even when crowded. If you just make a breeder, you can put 30 of them in a room and each of them generate energy, and true, they are only active for a small amount of time /cycle, but still they are easy to sustain with a refined metal vulcano.

Sedimentary rock is easier to get by with the fossil story trait. Input is diamond which can be made from coal 😀 Crushed fossil gives 95% sedimentary rock

Stone Hatch is definitely S tier. You can feed hatches tons and tons of sedimentary rock which you will never run out of and can keep feeding them sedimentary rock after they are mutated to stone. Then they produce lots of coal and provide tons of bbq. Stone hatches are free food.

Should some critters get buffed/nerfed?

❤

Would be nice if you included save files for the builds in your videos... Kind of impossible to reproduce them just by looking at them... Otherwise nice videos.

I think Beetas are worthy of S tier. Their uranium efficiency is 90 or 45% vs the centrifuges 10%, so they give you plenty of power. They just have to be kept cold and need dupes harvest the hives, no other interaction. It's very easy to create other hives to process a lot of uranium. They are very effectively used with the Saturn critter traps to make a large amount of sustainable hydrogen and even more if you flow some polluted water. Lastly, they make radbolt engines very easy to use with nuclear power, which IMO are the best engine to use.

how do you not have excess oxygen? My entire planet is completely filled with oxygen and I Have 4 full pipes going into infinate storage that never gets tapped into for thousands of cycles. Just place longhair slicksters in every room that can fit them for extra no effor tdecor. Your infinate spoms are running anyway, it does not matter to "use" the oxygen, because you are at max gas pressure of perfect oxygen anyway always.

@Sage Hatch: How can you renew dirt in a meaningful way? (Edit: OK, Pips. Guess I have to search your Pip-video) @Smooth Hatch: Huh? 75%? Did they nerf it? I remember them having a 100% conversion rate?

Damn. I so disagree with some positions and thats mean that Klei make a great game where you can play different styles and tactics

MOLTEN slickster. my problem with this variant is its body temperature and prefer temperature range which is very close to the boiling point of water 100 degree C. Everyone who play ONI knows that once steam is produced it is really hard to get rid of it and destroy stuff. For this reason i break every Molten slicker egg i find and hunt them down. i put a egg cracker on them on priority 9 always. just my view. i hate them sorry. LONG hair slickster they are great until they start laying normal slickster egg all over your facilities and before you know it, your base is full of oil !

15:01 I wonder how many takes it took to record

Smooth hatches are awesome, they don`t need to be operate to produce refined metal, plus generates eggs and meat. So I strongly desagree.

Why the hate for the longhair slicksters? They love normal base temps, they're cute, give a free decor bonus just by existing, and I am ranching them for meat at the meager cost of some water (which I have more than enough of) being pumped into my SPOM. I already have an overabundance of oxygen, so why not put it to use "feeding" this new meat source instead of having to constantly scrounge up rocks or whatever other food. I personally love that they just "eat" the oxygen already filling my base, and at temps already found in my base. So far, they've been one of the easiest meat sources I've tried to ranch. I know there are probably better overall critters, but I see them as perfectly viable for food, and at least deserving of a B tier.

In what way morb use of? Aside from oxygen generator
