50 cycle with 50 dupes without losing a single dupe. Now that something really Great and Exciting. I can't believe how you survive without losing single dupe. I never felt that excited while watching any ONI gameplay.

13:30 there is a crown next to each skill showing how many dupes and especially which dupe has got the skill. So from the start you could've seen that 3 dupes had hard digging, 1 had grilling, 1 had masterworks, 1 had mechatronics engineering and 2 dupes had plumbing.

Would love to see a critter dependent challenge series using every unique morph to maintain essentials such as refinement,power, morale, clean water ect.

even after seeing I still can't believe you managed to make it to cycle 50 without a single death! the first cycle was definetly the most intense with the almost instantaneous lack of oxygen Great video!

Looks like you're going to need to level up to 100 for 100! Good Luck!

A more competitive version of this challenge: Play normally, but you must adopt a dupe every time the Printing Pod is active (You cannot skip, and cannot take non-dupe items). The first time a dupe dies, it's game over.

Glad i didn't die in the first 30 seconds in cycle one. Loved this challenge.

What a novel concept for a challenge! The ability to survive the start will depend heavily on the starting conditions. I've always known that the optimum number of dups for survival is one.

I think the largest amount of dupes I've ever had was about 28, and that was my first colony. Since then I've stuck with 16 very specialised dupes and that runs a lot more efficiently, also makes it easier to deal with morale and oxygen needs. Long story short, 50 dupes would be far too much for me to even deal with, let alone my computer.

Normally not a fan on one off videos like this. But this was fun! I was so ready for that sound of a dupe dying being over lapped 10x times :D but never happened!

my ONI gameplay is held back by by my obsessive tendency to not waste any materials (e.g. rock crusher for metals, deleting fluids, etc.), no matter how insignificant. i think this chaotic challenge is just what i need to push myself outside my comfort zone and relax my self-imposed rules.

This game is like a commentary on how to get the most out of humans while dealing them the absolute least possible in return. The Dupes were thriving in this environment and were happy about it. Brilliant video btw.

ahahaha amazing video! Happy to have been a part of the colony! 50 50 was too easy, now let's try 50 100 💇

Good morning Echo! This was a fun challenge to watch. It was hot and heavy in the beginning, but I'm impressed they all lived. My shameless vote is "Pippy-Fifty" for the mascot. Keep up the good work and thanks for another great video!

As soon as I saw that Pip I immediately thought "oh no, he's about to cook it isn't he?" and then you reached 50 cycles. So my idea for a name would have been "lucky"

The little crown on the right of each skills tells you wich dupes already have it

10:13 that little white icon on some skills tells you how many duplicants have that skills. In this game you have 3 dupes with Hard Digging, 1 with Masterworks, 1 with Grilling and 1 with Mechatronics Eng.. If you move your cursor on that icon it will show you list of duplicants that have that skill.

Dupes can breath really little oxygen when they mostly hold their breath. In ideal circumstances, then can even survive off their own poop, though they will be much less productive. Their food can't be rationed like that though, but they do come with a natural reserve of 4000 kcal which is enough for a full cycle of mealwood. They are quite resilient.

The hilarious part is that in digging out all that space to look for muckroot so no one starves to death, you're decreasing total air pressure and making it less breathable lol

this was a very interesting video from an economic development standpoint, a normal run labour is one of the scarce resources so we try to automate as much as possible, in your case labour is the more abundant one so we use it to create the other missing resources as fast as possible rather efficiently as possible.

"breathing polluted air is not great." which just makes me remember your colony that had them breathing polluted oxygen for ages.

I love this challenge! Never thought you can do such short runs with ONI! :)

What an awesome video! ONI is one of those games that doesnt do too well for gameplay videos, but you managed to keep me at the edge of my seat the entire time lol. What an epic vid

Since you do weird challenges, perhaps you will do one Francis John refused. "Only Ranching". Once you can ranch a resource, you can only get it by ranching. So if you have a flux slug, then you can only use flux slugs. If you get a ore processing hatch, you can only process ore with hatches.

Absolutely AMAZING. I HAVE to try this! Thanks Echo!

Mush bars, the humblest of foods when you are in a pinch for something, anything to eat. 🙂

You can use Pneumatic Doors as airflow tiles. Put them sideways in the floor or ceiling and lock them so the dupes can't use them. Since you can place buildings on top of them, they're not a drawback.

I bought this game, this video was the final push that I needed to want to grab it. Love it so far, already past 100 cycles. Really enjoying it.

I'm still working out how to keep 3 dupes alive for 3 cycles. I learned a lot about priorities in this fun vid.

A note about digging oxylite. If I remember correctly, you lose about 50% of the tile's mass by digging, so it produces at the same rate but overall you get 50% less oxygen out of it.

Can we take this to 100 cycles? If you can survive props to you!

I love these wild challenges, they're my favorite thing to watch these days.

boy, that was fun HAHAHA amazing how all 50 dupes got to cycle 50!

While I commend you for this magnificent challenge, I have to deduct a point for breaking my number one rule. Don't leave a ledge over water. Unless I am intentionally funneling water, I avoid water contamination at all costs.

Congrats! I wasn't sure if you would make it. Very enjoyable video.

Wow, And ending with all 50! I'm impressed... I know I'd lose at least 15-20 in the first 10 cycles, LOL! Definitely going to give it a try though. XD Tyfs! Best of wishes to you and yours.

I think something that people tend to underestimate/misunderstand about the game mechanics the most is how difficult it is to kill a duplicant via suffocation. They must be totally incapable of reaching a single tile of any pressure of breathable atmosphere. As long as it is a breathable atmosphere of oxygen or polluted oxygen a duplicant will enter the "catching breath" effect which allows them to recover a portion of their breath gauge without actually consuming any of the mass of the breathable tile. Over time you will still be losing mass and they will of course be losing a lot of their active time to running for air when holding their breath gets too low, but because of this grace period buff you have a minute safety net so long as the dupes can reach the uppermost tiles of a colony where the low density air will inevitably collect. I've done the 50/50 challenge myself and found it relatively easy to be honest. The most important thing to do probably would be to start the game paused and immediately create a handful of schedules to offset bathroom breaks and divide your colony into groups. 5 schedules ended up just fine for me with 10 on each schedule.

1:27 funniest moment in the entire video.

It's kind of astounding that the colony was actually somewhat sustainable

Surprisingly, no one died wow. Also name for the pip should be emergency BBQ

I love ONI challenges. This was the first video I've ever seen of yours. Please continue videos or series like this. You have my subscription.

8:25 crying echo upgrade lol

My wife laughed when she saw my dupe was moved for snoring 😅

27:10 ... Call the Pip "Cent" .............. Like 50 Cent, got it? haha ..... lol

Amazing video, really interesting concept! Name for the pip: FiFi (For FiftyFifty)

Any ideas for similar challenges in the future?

nice run Echo, Meals on Wheels for the pet name :)

@13:27 - Least useful?! I'm the mos-..... yeah, that is pretty useless. YOU'RE WELCOME.

Now do this on radioactive planetoid. With no iron, no algae, no slime, only lumber and pips + mealwood :D. Now thats hardcore.

A fun fact is that dupes can be kept breathing on their own outhouse poop. It's not enough to avoid low oxygen debuff, but enough to keep them alive. I call it "a shitty solution" to oxygen.

Damn dude, that was impressive

Wow, just wow. I guess that's to be expected if you're a veteran ONI player :D (Meanwhile I'm here at cycle 150 barely keeping 15 dupes alive

Keep going to 100 :)

I can't believe no one died. But we won't talk about their living conditions. !DWU

That video was amazing I know I’m late but I just subscribed and can’t believe you don’t have more subscribers you deserve so much more.

I cant believe no dupe died O_O I fully expected them to die from their own stupidity

Next challenge: 75 dupes to cycle 75.

Insane, I’m shocked that it went decently alright

I am scared and panic when mu dupes are a little wet or a little stressed. I dunno how u do it, but I have a lot to learn haha loved the challenge!

Hey Echo, if you get a chance, you should check out Brothgar's old video over getting fast polluted oxygen with bottled polluted water. I usually build a system similar to his where a duplicant will pump some up, and try to run a bottle over only to have the door shut with a motion sensor, and drop the bottle out of range. Then use a water vent and liquid valve set to 0.1, and as it drips over the bottle, it tricks the bottle to putting out quite a bit of polluted oxygen. You can also use a liquid reservoir, and deconstruct when full to accomplish it without bottling, though it is slower over all than the previously mentioned method.

I've never felt so stressed out by a KZfaq video before lol

Spotted Waldo, I mean Echo, at 8:25 in the Advanced Power Regulation research box

I'm going to try this :)

great intense challenge

Maybe been mentioned, but looking at the skill tree, you can mouse over the "crown" to get a TT on who has the skills. This comment is based on @Echo finding 2 dupes starting out with hard digging, while the skills said there were three 😀

this was nice to watch

the mario sound affect did scare me😂 came outta nowhere

I guess I would start the challenge by intentionally drowning like 30 dupes so the other 20 can survive.

Every digging task destroys half of the dug material. If you dig 500kg of oxylite, 250kg will drop on the ground. Apparently the most effective way to collect resources is to melt them and then get them to precipitate into items instead of blocks, as the 50% destruction rate of digging is avoided that way. Fox Oxylite however, probably just let it sublimate.

I know this is an old video but uh, why no composters? It fixes the dirt problem really fast with that many dupes! Each outhouse usage produces what? 5 more grams of pdirt then the dirt you put in right?

Maybe the lit workspace buff would help a bit with those mushers?

50 hacth Challenge Love this

I would love to see a pt 2 of this challenge

I think algae should be a resource that can be produced, like if you leave an algae block touching polluted or fresh water and dirt, or just water, and it has a little light maybe, then it spreads/gets more dense, or a new, water planter box could be a thing, basically just a big jug of water. Also if algae is exposed I think it should naturally scrub Co2 from tiles nearby and turn it into oxygen, most of the plants should, if they're meant to be like earth plants and meant to use Co2. It would make those runs where you get unlucky with algae generation just a bit more viable

15:25 HEAR THE NOISE HE MADE 🤣🤣🤣🤣🤣

i can’t even get to cycle 50 with the normal amount of starting dupes without a few deaths

Honestly a great idea from a smaller creator, nice to see

okay but Hassan has to be in every colony 😂

Fantastic challenge. Really enjoyed this video - the jeopardy was real!

And know up to the 100 day and beyond there. Haha good play

MRE= meals ready to eat That's sounds like a great name 👌🏻

Dam this is the most interesting thing I ever see on youtube can you make more video to see how far you can play till the colonizer die

Hidden echo at 8:25! Don’t be so sad echo! 😂

Dupes are hardier than people give them credit for Also you definitely gotta name the pip Shameless Plug

Incredible. I love your content.

oh dam i didnt understand its over after 50 cycles :''( i want to see the futur of this colony ^^

I never saw so much digging on cycle 1

I like that, I will try it in my game

Would like to have more challenges like this,please.

I saw that Echo :D

I got surprised by This challenge and I also wanted to try as well! Thank you for your interesting video From Japan

Name the pet EMERGENCY MEAL >:) Note: I do not condone killing the fluffy wall-climbing dog for food :(

Pet should be name Emergency Ration. XD

12:12 you actually do have hard-digging dupes. There's no red icon at the dig command. Likely one of your many dupes started with some of the digging-skills.

Can't believe I didn't make it into the colony. Well done though, may give this a go.

I was in the video! I wasn't any duplicate though, I was the oxygenite at the beginning in the top left

Huh, not Dead yet. Thats we-ooo there we go…

Incredible challenge! 😄

Well you obviously made it this far, how much further can it go? How good can the quality of life get? Lets do 100 cycles
