75 Dupe Challenge Part 1 - Oxygen Not Included 

“You might see this as a bucket of pee, but I see it as a bucket of oxygen” god i love these kinds of runs due to the sheer chaos in the beginning

I still think you should run these challenges with a printing pod mod that disables dupes and only offers resources. While it might be a tiny bit easier that way, it is also more interesting, as you have a better chance to last till cycle 75.

You went and named each and every dupe? What a mad man, I salute you.

Huh, I did not expect this to last into another episode. Look at you keeping dupes alive, well done! XD Fun stuff, tyfs! Hope you and the fam are having a wonderful week.

Here's a couple of suggestions. Duplicate time efficiency, food and oxygen are your three priorities. Put in a power spine and put all the hamster wheels together. This will reduce travel time. Put only the minimum number of hamster wheels on the power grid to keep up with consumed energy. This will keep the duplicants on the wheel all day and reduce more travel time and use less dupes. Get hydroponic tiles down right away and plumbed in. Any new seeds can be planted into those. Get into ranching next because 249 bog buckets would be needed to keep dupes alive otherwise. Ranch everything and anything. You also need 10 grills to cook all the bog buckets. Only 6 micro mushers are needed to feed all the dupes. I've taken into account that 1/4 of the population might consume more calories.

How dare you not give me a Camille? 😤

Your series make me want to re-download this absolutely amazing game. I've been playing since just about the beginning of when ONI came out, and it just gets better every year.

I was trying this with 25 dupes and it was going amazing until cycle 40 when Max got pissed off and punched a wall. That wall happened to be the wall to the infinite CO2 containment cube, releasing a kiloton of CO2 into the base and rapidly outpressurizing the vents and oxygen production machines, i couldnt dig fast enough to diffuse the CO2 and EVERYONE DIED

9:49 adding the numbers to point out each building is an excellent little editing touch that makes a big difference in viewer clarity. well done, editing echo!

Good morning Echo! Loves these challenges you come up with. I got a good feeling you can make it to 75 cycles. Keep up the great work!

One other thing that this challenge requires - minimizing the height of the rooms. Meaning only 2 and 3 tile high rooms. This saves dupe travel time a bit, which for this challenge snowballs quite quickly.

chuckling at the 3 dupes named thyghostridder at 7:01 😂 love these videos :)

Hey there Echs, if you really need food for the 75 dupes, spindly grubfruit (or tended grubfruit if possible, better morale AND the food dropped by the plant at harvest is wayyy more than spindly) is the solution. All you need now is a pip, which sadly I don't think you can get one fast enough. Luma experimented with other x dupes/x cycle challenges, and pretty much all of them over 50 resulted in deaths after 30-40 cycles

I love these kinds of thing! Keep it up!

I don't know if it's still a thing but dupes used to breath less o2 when they had to hold their breath. I haven't played in a few months but I used to use it to my advantage.

I subscribed the day I found your channel and have been binging ONI videos! 😁 this one is fun if chaotic!

Absolutely love these videos, they are so good and i just end up watching them through and i can usually multitask but i cant bc im alot more intrested in watching theres this is amazing cant wait to see how far this goes!

For food with the goal of 75 cycles I'd try to start an automated pacu farm. Dupes can start with mechatronics engineering so if you gun for the research you could reasonably set up multiple pacu breeders that start their free food output by cycle 30. 15 breeders would provide 10 pacu every cycle. You'd need about 1k pacu to feed your dupes entirely off of free cooked seafood so with 15 breeders you'd have 1% of all future food needs per cycle. Just remember that it takes about 20 cycles for a pacu egg to hatch and die of starvation so each breeder will take 20 cycles to start producing its food.

These runs are pure chaos and I love it

Yay! Kiddo and I watch your mini base series to chill at bedtime. He's gonna be so happy there's another series now too!

An idea on oxygen generations, is to make "offgassing layers": - Make layers, 2 empty tiles between layers - Add a block on both ends, so water can stay on there 1 tile high - on one end, also add a Bottle Emptier (make the layer above smaller to fit it). Alternate the sides of the bottle emptier for easier fitting - Fill the level with polluted water, up to the endstops height - as one end is not pathable (1 tile height), Dupes will not path through them. While surface area for polluted water to offgas is maximized. - once done, fill the next level - bonus points if you can make it so one levels overflow will fill the level directly below. You should get 1 offgassing layer every 3 tiles height. And it easily stacks.

“Mouthbreathing hungryboys” is the best possible description of myself

Glutton for punishment. I love it! Keep up the great content

Mmm, I do love a challenge. And making a colony with 75 dups day 1... tickling my fancy lol

I love you're challenges, please do more of those with more "modifiers", like more dupes, science tree completed, i dunno, but would be fun! :D

YAS LETS GOO ITS SO AMAZING

Echo not having a dupe in a medical bed is a surprise.

I've never looked at mud and said "it's glorious food and water" until now

i see a new echo video.... i have to like and watch instantly :D

Hi Echo! Not my main account, but just wanted to say I enjoy watching your videos. I've been playing this game since close to it's start, and I'm still struggling to learn proper energy and labor distribution. It's better now but always a learning experience. That said, I was wondering if you're ever planning on doing a video about Shove Vole ranching. More specifically, Delecta Vole ranching. I know it's not the most sustainable until maybe late-game, but I just can't get Delecta Voles happy enough to start producing Tonic Roots; that's despite the food they eat is right and the right temperature. Again, just wondering if that's in your plans anytime soon. Either way, it's a joy to watch you play challenges and make tutorials on various aspects of the game!

love ur ideas and your videos a lot

Love your content! Is there such thing as a chaos mod?

If you find magma, drop polluted water on it to make sand.

I'm proud to lead the stress charge!

You can spawn dupes by holding alt or ctrl and hitting F2, no need for debug mode, I have accidentally done it a few times trying to get the automation overlay up while having fat fingers and no dialling wand

Hey Echo. I have a challenge for you! The "All Facts, No Printer" Challenge! Start a new game, now roll for the Spaced Out scenario with the most frozen friends you can find. Spoiler; After an hour, the most I could roll is 3 frozen friends among the 7/8 planetoid variants. Now the moment you load into the game, disable the printing pod. NO PRINTING ALLOWED. Now, colonize all asteroids with your limited crew. With the hermit story quest, expect to only have 7 dups work with by endgame! Should be a challenging experience. Let me know if find a seed with 4 frozen friends, I don't have anymore patience beyond rolling 3! I have a notepad of seeds if you want~.

The fact that it says “Part 1” makes me think you have a “Part 2 plus”.

oh great Im afraid of the dark now

5:08 75 dupes sick 😂

Insantiy.

THIS IS HELL!! A glorious dumpster fire!!!🔥🔥😆😆😆😆😆🔥🔥

Explore everything. 😉

Chaos!

I'd definitely would be using the flower pot food plant exploit to grow the Bog Buckets, as long as I can get a Pip in the early game. Might have to teleport to the second asteroid and hope it has a forest biome with Pips and Pip eggs to bring back to the main asteroid

Yo lets go another challenge

Another challenge similar to this could be you start with 1 dupe and add 1 every cycle

Ahh yes 😊 i always knew grilling was spelled c o o k.... 😂

I'm confused, I just bought ONI a month ago and don't have a lot of those buildings. Are you using Spaced Out?

have ALL mesh doors set to open. Disallow eating of mush bar until fried

have you considered doing the opposite? like a mini-series challenge with not 50 or 75 dupes, but just one. not a survival challenge, but to see how much a single dupe could manage, and maybe end it with say, getting to space, or if you're committed, the temporal tear. just an idea, though chances are there'd need to be a lot of cuts since projects would take a lot longer.

Thx!!!

Hey, I'm here twice! Yay! I'm as surprised as you that it's cycle 21 and still going... if anyone can do it, Echo can!

Uggghhhh posted 2 hours ago and part 2 in a week?! WHYYYYYYYYY?!?!

A great hall can +6 morale and is really cheap to get by to alleviate some dupe stress. But 75 of them needs like 5 lol.

You have a lot of dirt, just boil the pWater. Of course, you'll have to get plastic and such to do that. But, with the CO2 skimmer, and a CO2 vent, you have an endless supply of dirt, along with that pWater vent. Of course, most of that would be later game... and you'd have to find it first. But boiling Pwater using that minor volcano would be perfect... Of course, you should be food sustainable long before then I would hope.

So far so good. My guess is cycle 75! 🎉

23:00 64000 kcal is less than 1 cycle worth of food

Ah yes, Pee Water Included

Lol there are two ghostriders

what's bad with abyssalite breaks? i heard they suck but idk why

9:16 with 75 dups have idle dups is SO BAD...you should q up 10-15 dup wheels...5-10 more o2 makers..and 10-20 more massage tables..+ set it HUGE HUGE digging plans the whole map..and it is really late now but still needs to be done you should lay out HUGE food plots of everything...i mean at this point you should Q up like 200 planter boxes...AND like 10-20 grills and mush bar makers.

Which cycle you can survive till? The cycle that stutters your machine down!

Duping Dupes.

I could not eaven survive cycle 30 with 30 dupes and you are doing 75.

2LegitCity tried your 50 Dupe Challenge, if it says you anything. Lets see how far this one here gets

HUH !!!! you can just see the geysers from the starmap????

The pivot to mushrooms and blossoms will be real soon

This dude sounds like AI reading script

I dare you to try 750 Cycles >:D

oh :( my bog jellies

I beat the 3 dupe 3 cycle challenge.

Ctrl + F4, no need to restart the game to exit the debug mode.

How do you spawn dupes?

Overpopulation does not sound like a good , sustainable strategy ....
