Once the opening credits and cutscenes have finished, you’ll take control of Adie. After your AI, Allen, says “You’ll have to pull the manual release”, look at the Manual Release on your right and press 
to grab the lever, followed by holding 
to pull the lever.
Once you drop down on the Moon Surface, you’ll unlock:
Using 
, start walking into the direction of the blip on your Comms Device. Stay on the right side a bit, and once you pass through the big rocks for the first time, you’ll see a waving antenna in front of you. Walk over and examine with the Station by pressing .
Continue straight past the Station and keep following your blip. Cross the bridge that's found straight after you pass between two big rocks again. After the bridge, climb the Wall by using . Once you made it up the Cliff, cross the bridge on the right side. After the corner to the left, press to examine the Rock Pile, unlocking:
From the Rock Pile, continue slightly to the right until you see another bridge. When you try to cross it, the bridge will collapse, making Adie fall to a path below. Once you regain control, follow the linear path for a bit until you can squeeze through the opening by using . When you made it through, turn slightly to the left and move forward. You’ll quickly see another Station that you need to interact with, using . As you do so, you’ll unlock:
Continue to the right of the Station and follow the path until you walk under some arch made of rock. Continue until you see a second arch. Once you pass that, you’ll see a ladder, and the next achievement will unlock:
You can interact with the ladder, but it’s not required, so turn right and walk until you see an Exhaust Port. Use to jump over to the Exhaust Port. Once you’re in the tunnels, go right at the first intersection. Go left at the second and use to duck under the Crawl Space. Once prompted, use 
to turn on your flashlight. Look down, and use to enter the Shaft. Hold 
to shuffle forward.
Once you make it down, go right and at the next intersection, go left. Go right at the next one and straight across the next intersection. At the next one (where you’re facing a Vent Fan), go right. Halfway down the path, there will be an interruption of the pipes. Look left here and press to squeeze through the Gap. Continue forward and use to duck under the Crawl Space. Continue left, directly followed by a right, and you’ll see a Broken Fan. Use to examine it. Use again to crawl through. Go forward, look down a bit and examining the Shaft with . Use again to jump down. Move forward and use to enter the Shaft, followed by 
to shuffle forward.
Walk forward towards the green Console in the middle of the room and once you stand in the middle of it, you’ll unlock:
Examine the Console using . Once the conversation is over, use again to run a scan on the Console. After some more conversation, use to move the gyroscope on your Comms Device to a position that will make all bars light up. Do this two more times.
Meet Logic (she’ll be named later on, but I’ll refer to her as Logic as of the start), one of the base's AI. During the conversation, turn around and move towards the door behind you. Open the Floor Panel with and then alternate 
and 
to ratchet the Winch until the door is completely opened. Adie will close the Floor Panel herself. This will unlock:
After your save is loaded, you’ll be at the Console again. Turn around and move towards the door (past the Floor Panel where you used the Winch). Use to examine the Security Panel. After the instructions, use again to use the Security Panel. You’ll need to toggle the buttons so that a pattern appears. Fortunately, Logic will tell you what the pattern is, albeit a little cryptic at first, but she’ll give more hints eventually. For the first Security Panel, you’ll need to illuminate a square of nine lights right in the centre. Use to select a Button and to toggle the Button. See the image below for reference:
Now that the door is open, enter it, and follow the path down some stairs. Enter the Shaft Lift and press the Shaft Lift Button on the left side to move the lift. Once the elevator stops moving, exit on the right side and continue down the path. Press to examine the Power Station Door and enter the Power Station. You’ll be greeted by a different AI, Control. Move down the stairs during the conversation. Although Control can be quite demanding in what he wants you to do, go to the right once you made it down and use to examine the Crates. Move in between the Crates and examine the Open Crate. This will unlock:
Next, leave the crate area, and move to the other side of the room by going down, and then up some stairs. There are more things you can examine here, but we’ll skip them as they are not required. Instead, move to the three Generators at the far side and use to prime them. Pull down on 
three times and repeat the same process for the other two Generators.
After the Turbine fails, move towards the small Lift that goes down to the Turbine area. Use on the Lift Button to call the lift. Enter it, and the Lift will go down automatically.
On either side of the Generator are two levers. Use followed by to release the Turbine Latch. Do this for the other lever as well.
Ride the Lift back up and move towards the magnetic Crane opposite of the Generators. Use to board the crane, and then use to move the crane over the old Turbine. Press and hold to lower the magnet until it latches onto the Turbine. Release and the Turbine will be lifted. Move to the empty spot on the left, hold to lower the Turbine and release to raise the magnet. Now, use the same controls to pick up and pace the new Turbine.
After you regain control of Adie, leave the Power Station the same way you came in. Enter the Shaft Lift and, once you can, press on the Shaft Lift Button to start the Shaft Lift. Leave the lift on the left side and follow the path back up the stairs.
Keep walking forward, past the Console, straight to the door across the room. Logic will kindly illuminate the door for you. Use to use the Security Panel. This time, you’ll need to illuminate a big X on the panel. See the image below for reference:
Enter the door and keep following the path until you reach a big room. There’s plenty to examine here, but we’ll ignore it and continue up the stairs on the right towards the Airlock Door. Use on the Airlock Button to pressurize the Airlock.
After the conversation, and when the door opens, move forward into the Zen Garden. Meet Empathy, the AI that will set up lighting and oxygen for you. Keep right and walk towards the big Lantern in the Garden. After Empathy asks you if you recognize an object, use to examine the Lantern. After this, make sure you’ll interact with the other items in this section as well, being the Metal Object, the Plinth, the Statue, and the Carving. After interacting with all five items (for me it actually unlocked after four items), you’ll unlock:
Next, move towards the flowers left from the stairs. After some conversation, you’ll need to pick a flower that best represents you. I’m not sure if the choice matters for an upcoming achievement, but to be sure, pick the Purple Flower, like I did during my playthrough.
Turn around and move towards the centre of the pergola. Adie will sit down automatically and remove her helmet. When prompted to take a breath, hold and keep holding it, even when Empathy tells you to release. Just keep holding until Adie exhales automatically, and you’ll unlock:
Follow Empathy’s instructions to do two more breaths (hold until she tells you to release). After the breathing exercise, you’ll need to tap to raise yourself up towards the sky. After that, Adie will stand up and you’ll need to use and to balance yourself. When Adie moves to the left, slightly use and when she moves to the right, lightly use .
After this mind cleansing yoga session, move towards the stairs just behind you, next to where you picked the flower, and move up until you reach another Airlock. Use on the Airlock Button to pressurize.
Move to the next area and go into the small room on the left side. Exit out the other side, and use to interact with the first Welders Jetpack you see. This will unlock:
Go back into the little room, and use to examine the Controls. After some conversation, turn around and access the Electrical Panel. Use to select all five buttons, and then do the same on the five breakers. After some more conversation, and meeting a new AI, Pal, the power is rerouted, and you can flip the five breakers and click the five buttons again to restore power to the Controls. Turn around and move over to the Controls and press to use them.
After the pod gets stuck, move to the Welders Jetpacks, and examine the 2nd one (Equipment) with . Press again to use the Equipment. Press 
to use the Welder. Once Pal opens the fuel throttle, use again to see a bigger flame.
After some conversation, Pal will fly you towards the ice. Use to melt the ice and to control the direction. Use small bursts as that will prevent Pal from losing control. After you’ve cleared the first section of ice, you have to do the same with two more sections. Once all the ice is cleared, move back to the Controls and use to make the pod go down to the station. This will unlock:
Go inside the pod, and after some loading screen, you’ll end up on a new level of the base. Exit the pod and more down the hallway. Press to use the next security panel.
For the next achievement, you have to "solve" this security panel without making a mistake. This means you can’t hit a button twice. The symbol you’re after is a backwards Z, taking up the full space of the panel. You must only hit each button once, and it should take no more than 21 clicks to solve this. If you make a mistake, you have a 2nd chance in the 2nd playthrough. Use the below image as reference when solving this Security Panel:
If you made no mistakes, you’ll unlock:
Go through the door, and use on the Airlock Button to pressurize the next Airlock. Move into the next area and go towards the Security Panel on the other side. Use it with . After some AI hissy fit, turn left and go around the wall with the two lights on it. Wait until the next AI, Mom, is configured and after the initial talk press to use the Keypad next to the door. Mom will play the sequence, and you’ll have to repeat it by using to select the button, and to press it. Open and enter the door.
As of now, we’ll interact with everything we can. This seems to be needed for a later achievement. I’ve had some troubles getting this achievement on my first attempt, and there doesn't seem to be a lot of consensus on the requirements, so in order to play it safe, we’ll just interact with everything from now on, until we get that achievement.
Inside the room, examine the Map on the right side. Followed by the Banks and the Missing Bank in the middle, and the console on the left. Use on the console again to hack it. Like in the beginning, use to move the gyroscope on your Comms Device to a position that will make all bars light up. You’ll need to do this four times. Once you hacked the console, you’ll unlock:
Turn around and examine the map again. Turn right and go towards the balcony and use on the trellis that is covered in plants. Use again to start climbing the trellis, followed by to actually climb to the roof.
Look you your left and use to examine the Beam. After some conversation, use again to start walking the beam. Use to move forward. After some steps, you’ll fall down (this can’t be prevented). Turn around, climb the trellis and cross the Beam again. This time, when you lose your balance, use and to balance Adie, like you did during our little yoga class in the Zen Garden. Once you regained balance, move forward until you successfully cross the beam.
Enter the apartment, and use to examine the Floor Feature, the Art, and the Tube Access that is to the right of the Art. Next, move to the hallway and enter the door on your left and examine the Fixture. This will unlock:
Move out of the bathroom and use on the Door Button to open the front door. Go up the stairs and press on the next Keypad. Repeat the pattern and enter the apartment. In this apartment, examine the Tube Access again. Go to the balcony and look up until Adie mentions that she doesn’t see a way up. Leave the apartment the same way you came in.
Go up the stairs, unlock and enter the next apartment. In here, examine the Barrels in the corner of the room, after that, examine the Bed. Next, go to the balcony. Press on the trellis and use to climb up. Once you’re on the next level, ignore Pal’s idea of taking a shortcut.
Instead, move left and open and enter the first apartment on your left. In here, use to examine the Canister (1/19) that lays below the Tube Access, see image below for reference:
Once yet another AI, Jack, is configured. Examine the Canister again. Once again, move your ball on your gyroscope to fill all bars. For these canisters, you’ll only need to do it once. After you hear the recording, you will unlock:
From here on, you can use 
to let Jack input the code for you. Don’t use this option though, instead, input the code yourself!
Leave this apartment and go up the stairs on the left towards the next apartment. Open the door and enter the apartment. Inside, examine the Broken Furnature (typo not mine).
Leave the apartment, go up the stairs and use to examine the Broken Keypad. Next, enter the apartment and hack the Canister (2/19) that is inside the Tube Access:
After the recording finishes, examine the Art and then move to the balcony. Once again, climb up the trellis.
Once you’ve made it to the third floor, turn left and unlock and enter the apartment on your left. Inside, hack Canister (3/19) on the floor and Canister (4/19) inside the Tube Access:
Exit the apartment and go up the stairs on the left.
Unlock and enter the next apartment and inside, examine the Scarf. Next, hack Canister (5/19) on the floor and Canister (6/19) inside the Tube Access:
Before leaving this apartment, enter the bathroom, turn on your flashlight with and once in the bathroom, turn slightly to the right to see Canister (7/19) laying on the floor:
Leave this apartment and go up the stairs on your left. Just before the next apartment, look carefully in the planter to find Canister (8/19):
Continue where you were heading before finding that Canister, and open and enter the next apartment. Inside, examine the Portrait on the furniture and then look on the bed to find, and hack, Canister (9/19) and Canister (10/19):
Although you now know who Everett is, or was, we are not quite finished here. Leave this apartment, go down the stairs opposite of the apartment you just exited, and open and enter the next apartment. Once you go in, Control will turn off the lights, so hit to turn on your flashlight. This will unlock:
Proceed inside the apartment, and you’ll find Canister (11/19) on the floor, and Canister (12/19) in the Tube Access. Hack both of them:
Once done, turn around and examine the Art. Next, leave this apartment and go once more down the stairs and open and enter the last apartment, on your right. Inside this apartment, examine the graffiti on the windows, there are three different windows to examine, the others cannot be examined. Once you’re done with the graffiti, you’ll find Canister (13/19) on the floor, and Canister (14/19) inside the Tube, but a bit higher than where they usually were:
While examining this room and hacking the Canisters, Jack will mention this is the last room, and you’ll unlock:
Leave the last apartment and go down the stairs on the left. Examine the Security Panel next to the big doors. For this last Security Panel, you need to highlight just the corners of the panel:
Enter the doors you just opened, and use on the Elevator Button to call the elevator. Enter the elevator and the screen will go black for a bit, showing a loading animation. Once the image returns, there’s some conversation until the elevator stops and the doors open. Exit the elevator.
Proceed to the other end of the church. At pulpit, go all the way right and examine the Fire Pit, the Bedding and the blue barrels of Food. Turn the camera right and examine the Graffiti. Go back towards the pulpit and examine the damaged Wish Canisters on the floor on the right ride. Look up and examine the Cracks in the window. Next, go to the other side, past the pulpit and examine the Graffiti. Go back to the other side again and use to climb the Debris Pile. Use again to climb the next pile, and once more to climb until you are on the next floor.
Examine the Lightpost here, followed by the Pulpit in the middle. Go back and move behind the pulpit to examine the Camp, the Graffiti, and the Boxes. After a brief conversation, you’ll unlock:
Turn on your flashlight with and squeeze through the Gap using . Walk a bit forward and then look left, and right, to interact with the two Statue Plaques that are there. Move forward and look left and right again for two more Statue Plaques. Look down the path you’re going, and you’ll find Canister (15/19) on the floor:
First, examine it, and then use again to hack it and listen to the recording. After it finishes, continue forward and examine the Barricade. Next, duck under the Crawl Space. In the next area, examine the graffiti on the right, as well as the Air Tanks on the floor.
Before entering the small hallway, you’ll find Canister (16/19) on the left. Hack it:
Continue down the hallway until you reach an airlock. Once your helmet is on, use on the Airlock Button to pressurize the Airlock. Enter the funicular and use on the Controls on the right side. After you find out that the funicular doesn’t work, Control will give you an option to consider. After he’s done talking, it’s time to set up another savepoint for some later achievements.
You’ll be in the funicular again. Turn to the left, and examine the Broken Window in the funicular, as well as the Airlock Hatch in the hallway outside the funicular. Use again with the Airlock Hatch to open it. To unstick it, you’ll need to tap repeatedly.
Use to Enter the Storm. Follow the linear path until you’ll end up at a structure from the funicular tracks. Wait until your conversation with Allen is over, and Mom shows up asking you to reconsider jumping. Follow Mom’s advice, and turn right, dropping down towards a Path.
Follow this linear path, but make sure to keep your eyes out for things to examine. The first option is an Etching on a rock on the right side of the path. Examine it. Continue forwards and once you go through a narrower path, there’s another Etching on a rock on the left side. Examine this as well. Continue the path. When you are at a fork in the road, take either path as they will end up at the same spot again. You’ll walk into a Rock Pile consisting of 5 square rocks stacked on top of each other. Examine the Rock Pile. Once again, continue down the path. Once Mom asks about your parents, Adie should give an honest answer (considering that we bonded with Mom due to all the extra examining we did before). If Adie mentions what happens to her parents, you’ll unlock:
As you continue down the path, you’ll need to climb up a ledge with . A couple steps further, there’s a second ledge to climb up to. Continue the path ahead. Once you are near the end of the path, there’s a ladder structure in front of you. Use to open the Override and to use the Override. If you need help solving this puzzle, see below:
*** Spoiler - click to reveal ***The override needs to be set to the number 50. The switches act as binary toggles with the leftmost one representing 64, followed by 32, 16, 8, 4, 2, and 1. To get to the number 50, you need to toggle the 32, 16, and 2 switch (or OFF | ON | ON | OFF | OFF | ON | OFF)
Once the ladder comes down, you’ll unlock:
Use the ladder with and use to climb up. Once you’re all the way up, turn left and open the Airlock Hatch. Go inside and the screen will fade. Once the image is back, the next room will open automatically.
Go down the hall and go inside the second room on the right. You’ll find Canister (17/19) on the bed:
Examine it, then hack it and listen to the recording. You can examine the bed and the room afterwards, but this is not required. Exit the room and go further down the hall. Enter the last room on your left and use to turn on your flashlight. Inside this room, you’ll find Canister (18/19):
Examine it, hack it, listen to the recording, and leave the room. Finally, go to the end of the hallway and inspect the Relief on the left side. Use and to examine the following sections: Human Figures (bottom), Triangle Symbol (middle), Figure Symbol (top), followed by the Ring Symbol (slightly below the top) that now became examinable. Do a 180 and move to the other Relief. Use to inspect it, followed by using and to examine the following sections: Human Figures (bottom) and the Writing (top). After you regain control of Adie, examine the door. When prompted, use to speak to the door, you’ll need to do this twice. This will unlock:
Go inside the next room and turn right for a quick miscellaneous achievement. Go up the stairs and examine the Theremin. Press to use it, and you’ll unlock:
Press to back out of the Theremin and move down the stairs towards the console in the middle of the room. Put your cursor in the middle so that you can examine the Device. After Jack is done talking, use the Device with . As the recording doesn’t play, you can now hack it. This will be Canister (19/19):
After you listened to the final recording, you’ll unlock:
Next, use the lever on the right side of the Device. This will make a ball come down from the ceiling. Examine the Cavity on the left side of the ball. Return to the Device (DO NOT press the button on the left side), and use the lever on the right side again, then quickly move back to the Cavity and use to climb in. Once you rode to the top, you’ll unlock:
Press to exit the Cavity. Use to jump to the closest platform, and then keep jumping across the platforms until you reach the centre, larger, platform. There’s only one platform you can jump to at a time, so you won’t get lost.
Once on the centre platform, examine the Machine. After that, examine the Generator that is illuminated with green light. Use to use the Generator, followed by three times (or hold it) to prime the Generator. You’ll need to prime three times here. After priming, look around to find the misaligned Energy Beam (the one that’s not firing towards the spiked orbs on the centre platform). Jump from platform to platform towards the misaligned Relay. After some jumps, you’ll end up next to a beam you need to cross. Examine the Beam, and after some conversation, use again to cross the beam while Pal will block the energy for you. Halfway through, use and to balance yourself. Jump down to the platform with the Relay and examine it with . Pres again to use the Relay and use 
to aim for the spiked orb. Once done, you’ll unlock:
Jump across the platform on the other side, back to the centre platform. Move to the green lit Generator, and use to use the Switch next to it. Use to raise it.
Find the next Generator, which is illuminated in blue, and prime it using first, followed by three times per prime. There are three primes needed. Walk around the platform and look around until you see a smoking Relay. Jump from platform to platform using until you reach the Relay. Use to open and use the Override. Once again, you’ll have to put in a number, 113 this time. For help, see below spoiler:
*** Spoiler - click to reveal ***The override needs to be set to the number 113. The switches act as binary toggles with the leftmost one representing 64, followed by 32, 16, 8, 4, 2, and 1. To get to the number 113, you need to toggle the 64, 32, 16, and 1 switch (or ON | ON | ON | OFF | OFF | OFF | ON)
This will unlock:
Jump across the platforms, back to the centre platform. This time, it’s the same way you came from. Go back to the blue lit generator and Examine the Switch next to it, followed by another to use the Switch, and to raise it.
Move to the third and final generator, illuminated in red, and prime the Generator the same way you did with the other two. This last one just works and doesn’t require any extra work. So, move over to the Switch and to use it. As you can’t raise the Switch with , you need to tap repeatedly to finally raise the Switch. Once you succeed, you’ll unlock:
After some conversation with Grace, move around the platform until you see a small lift. Use to ascend, and as you do, some conversation, and afterwards, as the credits start rolling, you’ll unlock the achievement for reaching the Good Ending:
DO NOT SKIP THE CREDITS!
Let them roll out until a cutscene starts, involving your own ships AI, Allen, if all by himself now. Let the scene play until you unlock:
This is the end of the main playthrough where we got most of the story, collectible, and miscellaneous achievements. You should be at 29/35 achievements now. The next pages will describe how to unlock the rest, by going back to the saves we made earlier.
