Story, unmissable. Reach the base at the start of the game.
Story, unmissable. Set up your first outpost. The prologue walks you through placing it — follow the objective marker and confirm the build.
Story, unmissable. Create your first Alter in the Quantum Computer once the prologue unlocks it.
Pet the sheep. There is a sheep you can interact with — walk up to it and use the interact prompt. We have not verified exactly where it appears; if you cannot find it, check a community guide.
Story, unmissable. Finish the Prologue.
Start a production uphold. Once a production line is running you can set it to keep going automatically instead of re-queueing it by hand — do that once from the production screen.
Story. Survive the magnetic storm. Storms are timed events — get everyone inside and make sure the base has the shielding and power the event asks for before the timer runs out.
Upgrade the Quantum Computer. This is the module that creates Alters, so upgrading it is both an achievement and a practical priority — it gates how many and which Alters you can make.
Create your first batch of resources with the Refinery. Build the Refinery module, feed it raw material from your mining outposts, and let one production run finish.
Expand the base for the first time. Base expansion costs resources and is done from the base management view; do it as soon as you can afford it, because module space is the main constraint all game.
Learn this Alter's lesson. Lessons come from spending time with that Alter and seeing its personal conversations through — each one teaches Jan a trait. You need the Alter alive and on the base, and you need to keep talking to it as new dialogue becomes available rather than only assigning it to work.
Build a bridge over the lava river. This is a mapped construction project reached by exploring outward from the base — bring the required materials before you commit to the build.
Story, unmissable. Finish Act 1.
Build this Rapidium Ark. Arks are the main story-gated construction goals, so this unlocks as you push the mission forward: keep Rapidium mining and refining running, expand your workforce with more Alters so the build queue is not bottlenecked on one pair of hands, and make sure you have the module space before the deadline arrives.
Walk into an anomaly 20 times. Anomalies are hazards out on the surface; with the shield active you can enter them repeatedly. Grind this over the course of normal exploration rather than making a special trip.
Story, unmissable. Finish Act 2.

Story, unmissable. Finish Act 3.
Expand the base to maximum capacity. Every expansion tier costs more, so this needs a well-run economy: keep mining outposts supplied, keep the Refinery busy, and put enough Alters on construction to actually spend the material.
Complete this Alter's personal storyline. Each Alter gets its own multi-stage side thread that opens up once it has been created and has settled into the base: talk to it whenever a new conversation prompt appears, follow up on whatever it asks for, and keep its mood high enough that it stays willing to talk. Neglected Alters can stall or abandon their thread, so check the crew screen between shifts and keep visiting the one you are working on.

Build every possible module. This needs a maxed-out base plus the tech and materials for every module type, so treat it as a long-run goal on a save where you are not short on time.

Blow up the base. This is a deliberate destructive ending choice — it will end that save, so do it on a run you are finished with or immediately before reloading a backup.

Leave your Alters to the mercy of others. Another ending-type choice about abandoning your crew. Make a manual save first if you want to see the other outcomes too.

Start production of Phased Rapidium. This is a later-tier material, so you need the tech unlocked and the right production module built and supplied before you can queue it.
Place your first Terraformer. Unlock the tech, gather the build cost, then place it on the surface.

Complete every one of the Scientist Alters' storylines. This means creating those Alters and seeing each of their personal threads all the way through, which needs both the Quantum Computer capacity and enough in-game days to talk to all of them.
Give every Alter at least one personal item. Personal items are handed out from the crew screen — as you create each Alter, make a habit of giving it an item straight away so nobody gets missed.
Start production of Megafluid. A top-tier material: unlock it, build and staff the module that makes it, and queue a run.

Create every possible Alter. Each Alter comes from a different branch of Jan's life and needs the Quantum Computer upgraded plus enough Rapidium, so this is a long-run goal. You also need the base space to house them all.
Finish the Last Variable DLC. You need that DLC installed; it is a separate story arc from the base campaign.

Get an alternative tattoo with Naranath Bhranthan. This comes from a specific interaction rather than a build — take the option when it is offered.
Learn every lesson from your Alters. This stacks on top of all the individual lesson achievements, so it needs every Alter created and every personal conversation chain finished in one run.
Earn every other achievement in The Alters. Expect at least two runs: the ending-choice achievements conflict with each other, and the completionist goals need a save where you have the time and resources to build and talk to everyone.
