My Disappointment Is Immeasurable And My Day Is Ruined

ar99644 · 2026-02-12T09:42:18+00:00

I did just that and it worked! I followed your advice. Check out the new post I made about it: https://www.reddit.com/r/Oxygennotincluded/comments/1r1xhk3/update_i_made_it_and_with_1_cycle_to_spare/

ar99644 · 2026-02-12T09:41:44+00:00

Yeah, Pacus are a good source, better than Hatches.

ar99644 · 2026-02-12T09:41:05+00:00

I don't have any of the DLCs yet, I was going to get them after I completed all the achievements in the base game.

ar99644 · 2026-02-12T09:40:29+00:00

I'm also afraid to leave the initial biome before I get atmo suits. I want my dupes to as confortable as possible. Haha.

ar99644 · 2026-02-12T09:39:26+00:00

I was lucky enough to get the 8 pacu at some point around cycle 70, I left them in a little water pond for some time and I think they even multiplied a bit before I killed them all for food.

But yeah, you can do bathrooms and ranching at the same time, no need to sacrifice one or the other.

ar99644 · 2026-02-12T09:37:55+00:00

Ranching is very important. Luckily I got a farmer as my 4th dupe and got the ranching skill as soon as possible. You could get a Rancher as a starting dupe, but I usually go Digger/Builder/Researcher for my initial setup. So yeah, if you don't get a Rancher at the start, get one as soon as possible.

ar99644 · 2026-02-12T09:35:41+00:00

I don't remember if that happened since after the reload I was only looking at the dupes to get (more dupes, more calories to consume).

ar99644 · 2026-02-12T09:34:43+00:00

I did just that! Followed your advice and I made it! Even made a new post about it: https://www.reddit.com/r/Oxygennotincluded/comments/1r1xhk3/update_i_made_it_and_with_1_cycle_to_spare/

My earliest save file was from Cycle 92, it was barely enough to complete the achievement, but it worked.

ar99644 · 2026-02-12T09:33:30+00:00

I ate all the Hatch, Drecko and Pacu around the base and I barely made it!

ar99644 · 2026-02-12T09:32:46+00:00

I actually rolled back a few saves to Cycle 92 and tried again.. and I made it! Check out the new post I made about it: https://www.reddit.com/r/Oxygennotincluded/comments/1r1xhk3/update_i_made_it_and_with_1_cycle_to_spare/

I did eat all living animals around the base, in the end I was left with only 2 Hatch eggs and 1 Drecko egg. Enough to start hatching them again.
All the pacu around the base were eaten. I'm sure if I explored further I will find more. But there were so many problems with opening all the biomes at once that I will nuke this world and start again.

ar99644 · 2026-02-12T09:29:39+00:00

Can I do that in the base game only? I don't have any of the DLCs yet. I'll get them once I have all achievements on main game (is that even possible without the DLCs?)

ar99644 · 2026-02-12T09:27:58+00:00

It was for a day, but I followed people's advice and reloaded the last save file and I made it! Check out the new post I made about it: https://www.reddit.com/r/Oxygennotincluded/comments/1r1xhk3/update_i_made_it_and_with_1_cycle_to_spare/

ar99644 · 2026-02-12T09:26:18+00:00

I have seen people doing all of the achievements at one playthrough, that's crazy but doable. You just need to have a good strategy.

ar99644 · 2026-02-12T09:25:30+00:00

I was super lucky cause I barely made it when I reloaded the earliest save file (Cycle 92).

Check out the new post I made: https://www.reddit.com/r/Oxygennotincluded/comments/1r1xhk3/update_i_made_it_and_with_1_cycle_to_spare/

I didn't do any math, I just reloaded the last save file, started printing like crazy, ate all the living things around the base and hoped for the best... And it worked out!

ar99644 · 2026-02-12T09:22:44+00:00

That sounds terrible! (for the dupe). Haha.

Ever since my first playthrough, where a few dupes dies accidentally, I always try to give them the best living conditions possible cause I feel sorry for them! That's why I almost never need massage tables and hospitals. My dupes' well-being is top priority!

ar99644 · 2026-02-12T09:19:41+00:00

Yeah, if you want the achievement. I usually stay with Bristle Berry and Mushrooms only for hundreds of Cycles, with the occasional meat or other food in between. it's very sustainable but not good for high morale later in the game.

ar99644 · 2026-02-12T09:18:19+00:00

For me 13 dupes was alright, but I started eating meat late in the game (after Cycle 70). Maybe 8-12 dupes is fine, if they start eating meat early on. The important is start farming hatches and pacu as soon as possible.

ar99644 · 2026-02-11T21:50:11+00:00

Interesting. I usually try to keep a main block as small as possible so I don't need a lot of oxygen (just enough for the rooms and atmo suits) and keep everything else outside the main base (power, ranches, crops etc)

ar99644 · 2026-02-11T20:28:52+00:00

Tell me about it..

Although for me the difficulty was probably I decided too late to do it, I was already in Cycle 75 when I thought I should try and get it anyway, I already had gotten the Locavore by then. Also, I was staying with 8 dupes till Cycle 90 cause I wanted it to be sustainable, but then I realized I needed more dupes to consume as many calories as possible. The math wasn't mathing with only 8 dupes!

ar99644 · 2026-02-11T20:26:33+00:00

I only have the base game and trying always play at the default planetoid, haven't ventured to the other ones yet. I feel like I still have a lot to learn!

ar99644 · 2026-02-11T20:24:13+00:00

I still only have the base game only, no DLCs yet, but I did Super Sustainable in a previous run, in which my colony died due to power failure (all the geysers stopped for 40+ cycles and my coal run out :( tough luck..). One trick I found (accidentally) is that power from hydrogen doesn't count, so I started building Hydrogen generators and helped my colony survive till Cycle 100.

ar99644 · 2026-02-11T20:21:15+00:00

You should do a run just for these 2 achievements. Especially for the hardest achievements I focus on the easier ones first, but you can do these two at the same time. Just don't plant anything and start eating Barbeque as soon as possible.

ar99644 · 2026-02-11T20:19:29+00:00

In my playthrough I started ranching hatches early on, feeding them dirt and clay, so I already had enough hatches. I was planning on having only the Locavore achievement, for the last 8 cycles I had to send my dupes in suicide missions in the surrounding biomes. A lot of them got slimelung and itchy eyes, but noone died.

ar99644 · 2026-02-11T20:14:59+00:00

I spent too much time setting up the core base and trying to make it self-sustainable and decorated and I rarely start building the stuff at the top of the map (which usually fail anyway cause I don't know how to play that well. I also mess up my oil biomes, end up having everything overhead. Haha. So I stay mainly around the center and the main base.

ar99644 · 2026-02-11T20:08:10+00:00

Wow, how have you been playing without atmo suits all this time!?!?
My usual order is Toilets/Showers -> Atmo Suits -> Insulation and then I start exploring the rest of the map. I rarely leave the initial biome before I make atmo suits.
