50 dupes for 50 cycles Challenge | Oxygen Not Included 

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!

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

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.

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.

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.

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.

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

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.

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.

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

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

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

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

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.

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!

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.

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.

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

People who can't last 50 with 3: ☠️☠️☠️ That one person who can do it with 50: 😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁

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.

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

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

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.

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.

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

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

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.

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

this was nice to watch

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

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

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

This was a lot of fun to watch! ❤

Brilliant challenge and very entertaining video!

Incredible challenge! 😄

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.

Damn dude, that was impressive

Insane, I’m shocked that it went decently alright

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

great intense challenge

I'm going to try this :)

Great videos they're well edited

Now this is high quality content

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.

Would like to have more challenges like this,please.

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.

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

Would love to see more cycles of this

I really like these new challenges lol

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!

This video made me subscribe! :D

This was a fun episode

Hah, love the intro!

What a cool challenge!

I would love to see a pt 2 of this challenge

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

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

Keep going to 100 :)

Any ideas for similar challenges in the future?

8:25 crying echo upgrade lol

Would love to see how you continued!

1:27 funniest moment in the entire video.

50 hacth Challenge Love this

I like that, I will try it in my game

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

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

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

All of them survived? Thats crazy^^

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

Yay another video :)

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

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

That was stressful XD

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.

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 😀

I've never felt so stressed out by a RU-vid video before lol

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

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

Very, very impressive.

Wow all 50 lived that’s awsome

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

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 never saw so much digging on cycle 1

the mario sound affect did scare me😂 came outta nowhere

Wow that was surprisingly enjoyable. Next attempt 100 dupes right from the start? :D

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

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.

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

Your A Legend

fun challenge!

what a challenge

would be awesome to see how long you could keep it going ;)
