Subnautica Walkthrough

4. Story walkthrough (PC)

We'll be using the developer tool in the game. You need to activate it by pressing F3, then allowing your mouse to move around by pressing F8. Then disable the disable console option. Commands can be entered by pressing ENTER and then typing the command, pressing ENTER again afterwards.
Keep in mind that the commands that you have to type in are case and space sensitive!

With that out of the way lets fire up the game

Start a game in freedom mode. Start by hitting 'Escape' as you see the cutscene, this should skip some unnecessary steps and paused the game so let's get to it by opening the developer menu with F3, then F8 to allow the mouse to move freely, then unchecking the 'disable console' option at the top. Now to enter commands, press ENTER, then type the command and ENTER again.

Enter the following commands: explodeship, nocost, nodamage, oxygen, fastbuild, fasthatch, unlockdoors, infect 50, item builder, item precursorioncrystal 2, item precursorkey_purple, unlock all, fixleaks, and item cutefishegg

Now facing the ladder on the left of you will be a fabricator use that to build the Mobile vehicle bay (Second option under the third menu Deployables) and Hatching enzymes (First menu Resources, Second menu Advanced materials, sixth option) Open the developer menu and enter the command goto wreck1, swim to surface, as you are you will get a prompt to use your mouse to build the mobile vehicle bay so do that (you can only build it when you have the item in your hand). Don't worry, as it'll float to the surface.

Hop onto the Mobile Vehicle Bay and Build Prawn Suit, Cyclops and Seamoth. Build Neptune Launch Platform. Once completed swim to it and climb the ladder to find another interface to build the four stages of the rocket.

Swim down to the ocean floor under you and build (with the habitat builder equipped) the Multipurpose room (First tab, third option, second row), build Hatch to enter (First tab, first option, third row), go inside and build Alien containment (Third tab, first option, second row), build hatch on side of alien containment, climb in and open your PDA with 'TAB'. Drop the egg inside, wait for cuddlefish to hatch and pick it up, go outside and let cuddlefish go by opening up your PDA and dropping it from your inventory.

Time for the location based achievements. If you've read the tips you'll know some of these are very random so follow any instructions or suggestions I give and explore a bit if you feel more comfortable do a little extra to be on the safe side. I didn't originally intend to handhold here as it's really not needed but I've included a few screenshots of entrances or what you're looking for. BE SURE THAT YOU CHECK THE NAME OF THE PDA'S YOU PICK UP. There are multiple PDA in every base, and thus you might pick up ones you don't need. Also, when it gets dark remember to use the 'day' command.

Command: goto base1 - Find the open door on the side of the long tube section, enter and turn right to pick up a PDA titled Degasi Voice Log #2 - Storm! Upon spawning, go outside past the desk, then to the hatch in the tube section. In the corridor, it is the PDA on the right.

Base 1


Command: goto base2 - go through broke off hatch section (right-hand side on the other side from where you spawn), turn left in the room and head down the corridor at the intersection head up the ladder, at the top of the ladder head left to pick up a PDA titled Bart Torgal's Log #2 - Stalker Teeth in the windowed dome structure.

Base 2


Command: goto base3 - enter the third story open hatch (center of the base on the other side from where you spawn), there is no light and it's pretty dark so once in you'll likely hit an aquarium in the middle of the room you want to go to the opposite end that you entered and find the ladder down, swim down to this room to pick up a PDA titled Degasi Voice Log #8 - Risk Taking on the desk to your right. It can be a bit tricky to go down the ladder, just stick at it.

Base 3


Command: goto LostRiverBase - Wait for the base to load and swim inside to trigger some dialogue from your PDA about the walls being reinforced.

Command: goto LavaCastleBase - Seems to be random. You're trying to get another dialogue to pop. It has popped with one load up for me once. One speed run it popped the second time around and on another account, I swam into the base, ran all around it, then exited the other entrance and swam up and over the top back to where I started. It popped when I almost got to the door I started at. Another run, I swam around above the base on a reload for about ten seconds before it popped. I'd recommend waiting for the base to load and then swimming above it a little when teleporting here to see if it'll pop for you the first time here otherwise you may have to reload your save and teleport here again later on.

Command: goto aquarium - Wait for it to load enough for a speech to start.
Command: goto incubator - Under you should be a little stone pillar of sorts.

Incubator

(If you haven't already, item precursorioncrystal 2 to give yourself 2 ion crystals) Place an Ion crystal in the stone pillar to power up the incubator. Walk forward to the popped up interface that's now in front of the eggs and place your hatching enzyme into it. Turn back around and swim up what looks like large stairs/ramp until you hit an archway. At the archway, you'll wait for a cutscene of sorts where the sand around it gets blown away you'll see it clear sand away from a pillar like the one you just used place your other ion crystal in here and enter the portal that appears. Now, wait till you see little orange bubbles pop up around you as the creatures pass by you, interact with one.

Cure


Command: goto gun - insert the purple precursor key into the stone pillar, in order to open the door. Afterwards, enter the structure and follow the corridor for half a minute to reach a terminal. Interact with this terminal to get an audio cue.

Command: goto gunterminal - interact with the terminal to shut down the defenses of the area. The terminal has to disappear. If it doesn't try again or teleport again to this location and try again.

Command: goto wreck1 - (Don't launch the rocket until you're told to do so!) swim to your Neptune platform and climb up, walk around to the gantry and activate the elevator, enter rocket, activate auxiliary power unit, communications array and hydraulic systems by flipping their respective switches on this level. Climb ladder, boot up primary CPU at its terminal, activate life support systems at its terminal, prepare time capsule by typing anything in the message box, taking a screenshot, selecting the image with your mouse and then choosing select at the bottom and by leaving an item in the box by moving one over from your inventory and then exit with TAB (you will know you've done it right if it says "Time Capsule Ready"). Then turn to the chair...

STOP

Here is where we're going to pull up the pause menu and save. If you read the tips you'll know to wait till the icon in the top left disappears then exit to the main menu.

Reload your save. During the loading screen (expect 2 minutes or so) you will see some random achievements popping at various times (you won't see all of them pop up and which ones do varies). When it's completely loaded we should be at 15/17 and only have the last two left to do.

If you still have a couple of achievements left, you can retry the steps up above or load up other teleport locations with similar names and wait until they load and move around. I usually just repeated whatever locations teleport I was missing, saved and reloaded and they'd pop. If you're having any trouble, shoot me a PM or comment on the forum walkthrough and I'll try to help you out with what to do.
