The Roadmap to Victory in Oxygen Not Included (Base Game)

As requested, here's a text version that breaks down the steps and an estimated, EARLIEST cycle you can get there safely. It's totally fine to get there later than the cycles listed, or to do some of these in a different order depending on the map you're playing on and how quickly you are taking duplicants. Just keep in mind that deviating from the walkthrough steps will change the shape of the run, since resources will be spent much differently than what is implied with this order/timing. Keep in mind that these are just estimates!
