This achievement guide contains all achievements in the game, and the goal of this guide is to be as descriptive and clear as possible so you can easily get the achievements. There is an area for specifically demo achievements. There are 4 categories in the guide, and here is what they mean:

Progression Achievements refer to achievements that you can get by just progressing, climbing, and playing the game normally and as intended.

Death Achievements are the achievements you have to die for. Dying but getting revived using a floppy disk will still count for the death achievements.

Item Achievements refer to all of the achievements you have to use items for. These are mostly easy or just incredibly time consuming.

Secrets and Challenges are basically miscellaneous achievements. They contain everything that doesn't fit in the other categories, such as hidden secrets you would have to find or interesting things you have to do.

Enigma refers to the INCREDIBLY complicated, long, secret achievements. These usually require a lot of progress in the game, and require you to do something other than progress the campaign normally. Achievements like these are not in the demo. (maybe I'll come up with a better name for the section later)

Complete the tutorial. The tutorial can be found by pressing play, and clicking the tutorial box next to campaign. The end of the tutorial can be found after swinging on the rope in the Rebar room.
A screenshot taken on the platform that is one swing away from finishing the tutorial.
Reach Pipeworks. Pipeworks is at 600 meters, and can be found after Interlude Lockdown in the campaign. Once you reach Interlude Lockdown, it will indicate it on your screen, and you'll be in a big circular room with giant yellow text on the wall that says "HABITATION." Continue through the room, and then press the button on the wall next to the elevator. After you jump to the other side of the broken elevator shaft, and you've reached Pipeworks!
A group of images taken in Interlude Lockdown.
Reach Habitation Yellow. After climbing Pipeworks far enough in the campaign, you will reach Interlude Ascent at 1200 meters. Don't waste any time here, because the mass is NOT waiting at this part. Go to the elevator, and press the button. You can climb on top of the elevator if you want. The elevator will go up, but the announcements say you need to deactivate three elevator security locks. The elevator will stop, and you have to press all 3 of the buttons, which are never randomly generated, unlike your previous gameplay. Once you press all 3 buttons, make it back to the elevator. The announcements will then say you have to do some airlock thing. There is a big yellow box you will have to make it to. The mass is kind of fast here, but you can do it quick by saving up 4 (or 2 if you're good at the game) rebars of any type for this. Use 2 Rebars to boost to the platform under the yellow box, and 2 Rebars to go back. This method is pretty difficult though, so if you don't want to do that, you'll need to have a Rebar Rope saved. When going on the path that is accessible without items, you'll get to a part where there is a 4 tile platform a Rebar on the wall near some triangular sort of part sticking out in between a 4 tile platform identical to the one you're standing on. Put a Rebar Rope on that part, and swing on it to the identical 4 tile platform on the other side, and keep going from there. When you get in the yellow box, press the button, run back to the elevator, and press the elevator button, or wait for the timer. The elevator will take you to Habitation Yellow. There is no mass here, although there is multiple other hazards. Good luck.

Reach The Abyss. Beat the current campaign for now at 2200 meters. There are (as of now) four main zones, Silos, Pipeworks, Habitation Yellow, and the Abyss. Beat Habitation Yellow to reach the abyss. The end of Habitation Yellow is simple, so don't worry. Habitation Yellow itself is hard. If you are scared of losing progress in Habitation Yellow, get a free floppy on the Forlorn Gateway crane, get a x2 floppy at Forlorn Gateway's checkpoint, watch a walkthrough of the game to get a good understanding of how Habitation Yellow is, and read my creatures and hazards guide if you want.
Evacuate immediately.
Reach The Abyss in Hard Mode. Once you beat the campaign (reach The Abyss normally) you will unlock Hard Mode, along with some other things. Toggle on Hard Mode, and beat the campaign with Hard Mode enabled to get this achievement. WARNING: HARD MODE IS HARD
A turret spotted in Hard Mode Silos.
Reach The Lost Pier. The Lost Pier is very interesting, because you can only get to it in Endless Substructure at 1500 meters. You have to beat the game to unlock Endless Substructure. If you are planning to do this achievement, I also recommend learning a bit about the Sight, Sea, Light achievement.
<- Hover over black box to see image (spoiler)
Why did people use this place as a pier this is not a reliable area
Loop back to Silos in Endless Underworks. This is very easy. Essentially, you're just playing up until Interlude Ascent on Endless Underworks. Underworks contains Silos and Pipeworks, so once you climb far enough to where you would reach Interlude Ascent, you'll get the badge.
A connection between Pipeworks and Silos.
Loop back to Silos in Endless Substructure. This is harder than beating the campaign, because The Mass never stops. Just play Endless Substructure, make it to where The Abyss would be, and you'll get looped back to silos.
A connection between Habitation Yellow and Silos.
You sure this is safe? You get this achievement by getting an Experimental modifier in the Silos Break Room at 300 meters. This achievement used to be broken since release, but got patched on April 23rd 2025.
The experimental research computer.
You feel stronger. You've felt this pain before. There is a checkpoint area in Interlude Lockdown, and at Forlorn Gateway. These checkpoints have computers, and Floppy Disk shops. Get a modifier at the computer in one of these checkpoints, and you will get the achievement.
The modifier computer.
You will get climb 2k meters and any lower achievements by beating the campaign, leaving 5k meters and 10k meters. You need to play any endless mode for these last two. The Mass caps at 2 meters per second, and The Mass moves in Habitation Yellow if you're in endless.
This is you by 10k meters

Plucked from the periphery. Don't forget: it lies. There are two special checkpoints in the game, one in Interlude Lockdown, and one in Forlorn Gates in Habitation Yellow. You can use Floppy Disks in the computers at the checkpoints as a revive system, as well as buy Floppy Disks at both checkpoints. When you have a floppy disk ready, next time you die it will revive you. If you die and get revived with a floppy disk, you get the achievement. As stated in the guide description, you can get any of the other death achievements even if you get revived with a Floppy Disk.
The weird things that appear on your screen once you get revived with a Floppy Disk.
Die to a fan in Air Exchange. Air Exchange is one of the sub-regions in Silos. It indicates you are in Air Exchange by the white text that appears on your screen telling you where you are. Touch a fan, and you'll get the achievement. Starting the campaign makes you start with Deep Storage, so start an Endless game and restart until you start with Air Exchange.
A fan.
Get eaten by a Barnacle. You can find Barnacles very easily by starting a campaign in silos. Barnacles are incredibly abundant in Pipeworks too. Barnacles do not appear in Habitation Yellow. To die to a Barnacle, let its tentacle grab you, and don't break the tentacle, and let go of everything. If it is grabbing you and you are close enough to it, it starts eating you. Then you die and get the achievement. Start Endless Pipeworks if it is available, or campaign, and keep going until you hear or see a Barnacle to get the achievement easily.
A Barnacle.
Get crushed. You will find crush-spike thingies in the Shattered Chambers sub-region of Silos. Wait for it to crush you, and you get the achievement. Start Endless and restart until you get Shattered Chambers. If you know the rooms with the crush thingies, restart until you get one of the rooms in Shattered Chambers that have the crush things.
A couple of crush thingies.
Die to a Bloodbug. Bloodbugs can be found in Silos, but are very common in Pipeworks. Bloodbugs are nearly impossible to die to from being damaged, but if a Bloodbug hits you into the mass, it counts for the achievement. Start Endless Pipeworks, or explore the campaign, and wait until the mass is pretty close, then let the Bloodbug hit you off.
A Bloodbug found in Drainage System.
Die to steam in Pipe Organ. Pipe Organ is one of the sub-regions of Pipeworks, and is the only place you can find steam at. Start Endless Pipeworks if available, or go in a campaign, because Pipe Organ is guaranteed in the campaign. Let the steam push you into the mass, similar to the Bloodbug achievement, and you'll get a new achievement, and hopefully not a new hatred. (pls give me hilarous awards)
Steam boiling me to death.
[CENSORED] Die to Vern AKA Teeth AKA Mr. Teeth. You can find this entity at the start of Habitation Yellow. Go into Habitation Yellow, and progress until you reach the Service Shaft. You will meet him very soon. He is hungry.
An unfortunate player being harassed by Vern AKA Teeth AKA Mr. Teeth.
You let go. Die to the vent thing. The vent thing is a monster that looks like a hand, a White Knuckle if you will, and appears in the Delta Labs sub-region of Habitation Yellow. If you look at it, it'll run away, so don't look at it, wait for it to grab you, and let it pull you into the mouth thingy it resides at. This achievement used to be broken since release, but got patched on April 23rd 2025.
I'm venting my thing right now

Place 100 navigational tools. This includes pitons, auto pitons, Rebars, and Rope Rebars. You can check progress in the Logbook by adding the total amount of these items used.

The items that count towards Pathfinder.
Place 100 pitons. Pitons are rather common, and you don't even have to hammer in the piton to count towards the achievement. Auto pitons also count towards the achievement. You can grind this easily by starting a campaign, using the piton on the floor, and restarting. You can check progress in the Logbook.
Exactly 100 pitons.
Throw 100 Rebar Rods. This is basically the same as construction worker, except with Rebar. Any type of Rebar counts, which makes this easier. You can grind this easily by starting a campaign, using the Rebar on the floor, and restarting. You can check progress in the Logbook.
Exactly 100 Rebar. I would've put in the picture with 100 thrown Rebar, but this looks prettier.
You Monster. Smash a grub. Smashing grub allows you to grab onto anything for a short period of time. You can find grub easily by finding them at secret locations. Grub is very abundant at secret locations, and if you want to know where secret locations are, I recommend this channel. They have uploaded multiple videos with secret rooms (among some other content) and most, if not all of the secret areas have grub in them. If you find a better resource for secret rooms, tell me. When you use 2 grub you unlock grub in the vending machines, which is pretty helpful for the Endangered achievement below.
Stupid baby screaming on the floor.
Commit 50 crimes. Yep... you have to smash 50 total grub. Buy them at vending machines for 7 roaches, or find them at secret spots. The only extra advice I can give that isn't in the information for the Criminal achievement, is if you have a grub and want to use it, put it in a pocket, and if you're about to die, use it out of panic. DO NOT underestimate how safe you are. There has been at least 3 times where I don't use it immediately when I'm about to die, and then I die without using it, and possible achievement progress goes down the drain. You can check progress in the Logbook, by looking at the "Crimes Committed" counter.
A considerably large amount of grub.
Carry a grub in one hand up 500 meters. This is very difficult. Conserving stamina with one hand is undoubtedly hard. I recommend doing this achievement early in campaign or endless. Also, if you use any modifier computer, the grub goes out of your hand. I learnt this the hard way. You can use vending machines, but don't go on a modifier computer. There are many rooms in Deep Storage that have an easy early grub location. Whenever I manage to get a screenshot of those locations, I will add the grub screenshots here.
Grub Location 1. This room can be found once you have a certain silos unlock in the logbook, I am unaware of which one though.

Grub Location 2. You can find this in the room with the big cylinder in the center.
PHD and everything. Launch yourself using Explosive Rebar. Explosive Rebar can be found in some secret rooms, easy to access spots, or rarely right in front of you at the floor in one of the Pipeworks Drainage System rooms. Use the Explosive Rebar at your feet, and you get launched really high for the achievement. Getting launched by the Red Roach also works.
Flew away so hard I can see the spritesheet...
Surprisingly useful. Launch yourself using a Flare Gun. You find the Flare Gun at the checkpoint in Forlorn Gate in Habitation Yellow, including a box under the Flare Gun with ammo. Use the Flare Gun midair to launch yourself, towards somewhere, and you get the badge. This feature is helpful in the Service Shaft.
Climbgirl aggressively throwing herself in the air by shooting a flare gun downwards.
Bank 50 Roaches for Middle Class, 100 for High Paying Job, and 500 for Too Big to Fail. This is very grindy. You can bank roaches by picking them up, and using them at the roach hole in any vending machine, or the Modifier computer and Floppy Disk shop at the special checkpoints. You can only pick up gold roaches and platinum roaches. Gold roaches are golden and shiny, and are worth 1 roach when you bank it at a vending machine. Platinum roaches are platinum and very shiny and sparkly, and are worth 5 roaches when you bank it at a vending machine. Platinum roaches are rare at the start, but are very common later in the game. You don't have to take my advice, but this is what I feel is the most useful strategy you should do immediately. For the rest of the time you play this game, focus on roaches. Drop things in your inventory if you need space, just focus only on roaches. One time I had like 15 roaches in my inventory, including some platinum ones, but I had almost no items, yet I was able to bank it all and get a lot of money. Focusing on roaches can really help in the long run. You can check progress in the Logbook. Something VERY important you need to know, is that the achievement only counts current roaches banked. It does not count the full total. I feel like the best grinding method is to put a bunch of revives into Habitation Yellows computer, go to haunted pier and explore every nook and cranny to get a bunch of roaches, revive, and repeat. You can get a free T2 disk in Interlude Ascent when you have to do an airlock mechanism thing, there is a platform somewhere behind the elevator and on top of a shipping crate on that platform is a T2 floppy disk, and you can get a T1 floppy disk from Lookout Duty, right after Interlude Ascent in Forlorn Gateway. And then you can buy the t2 disk at Forlorn Gateway as like an investment. This works because roaches respawn when you revive.
500 roaches banked.

Forgot your keys. The easiest achievement in the game. Start the campaign and you'll be put in Silos. There is a door that closes and it connects each room to eachother. If you go above the door, it will start to close. If the door finishes closing on you, you die, but if you go under the door before it closes, you'll be trapped in the room, and you'll get the achievement while also noticing that the mass actually catches up for every room passed.
The door to the first room shuts and soft-locks your run.
Fall 50 meters. This is very easy. If you press F3 on your keyboard, it will show you the ascent you are at which can make this effortless. It doesn't matter if you fall to the floor or get consumed by the mass, as long as its 50 meters in one fall you get the achievement.
Climbgirl falling from a concerning height.
Somebody else has been here. You can either get this by normally progressing very rarely if you get the Silos room that has the art right there in the main climbing route, or you can go in a secret room. If you want to know where secret rooms are, I recommend this channel. They upload videos with secret rooms (along with some other content) and if you go in any of those secret rooms with art on the wall, you'll get the achievement.
The rare art you can find without straying from the main path.
Smash 100 Roaches. You can smash any roach, however, I don't recommend smashing gold or platinum roaches because you can bank those at vending machines to buy things. If you collide with an area a roach is at, you'll smash it.
They don't suspect a THING.
Pet a Strider. Striders are completely harmless and invincible creatures that can be found in Pipeworks Waste Heap. You can climb anywhere on a Strider, except some weird little small dinosaur hands on it or something. If you repeatedly click anywhere that isn't it's legs, such as its shell or mouth, you will get the achievement for petting it, and the Strider reacts a little bit to your kindness. Also, it's name is Henry.
A Strider.
Bounce off a gasbag. Gasbags are blimp-looking floating creatures that appear in the Pipeworks Waste Heap. They fly around slowly, and if you are near them they slowly chase you. If you touch them, they explode and push you away hard and do a tiny bit of damage, but if you jump on top of them, you bounce off of them really high, and get the badge.
A gasbag.
Don't look down. Climb to the very top of the crane holding the elevator at the start of Habitation Yellow. There is also a small room you can find on your way up where you can get some loot at, but the top of the crane is what you're looking for to get the badge and also some loot there too.

Death, Death, Death. One of the most complicated achievements in the entire game. Everything you need to know is in the name and the description.

Go to the Lost Pier, use the Blink Eye two times for it to restock in the vendor. Start the campaign, and die 3 or more times. Refer to below text to see easy places you can find Floppy Disks. After you've died at least three times, bring the Blink Eye to the Haunted Pier. You can find Blink Eyes from vendors all over the Haunted Pier. Once you are at the Haunted Pier, go up to the big radio tower. Once you climb up to the top of it, a rift will appear. Teleport into it with your Blink Eye and you get the achievement. (You can also jump into the rift if you opened the rift using the eye)

You can buy a 2X Floppy Disk at Forlorn Gateway, you can get a free 2X Floppy Disk in Interlude Ascent when you have to do the airlock seal thing and the elevator stops go on the platform behind the elevator sticking out with a Floppy Disk on a shipping crate, and there is a free 1X Floppy Disk at the Lookout Duty achievement. You can also just get the Disk Jockey experimental perk because that's a 3X Floppy Disk.
Some Sight, Sea, Light graffiti on the floor.
What a thrill. The hardest, longest, and most complicated achievement in the game. Keep trying, you'll get it.



THIS ACHIEVEMENT WAS RELEASED AFTER I MADE MY ACHIEVEMENT VIDEO GUIDE, IF YOU WANT TO WATCH THE VIDEO VERSION OF THE LADDER ACHIEVEMENT, WATCH THIS VIDEO

To get this achievement, you need to have the Blink Eye item unlocked in the vendors, or find it in endless. To get the Blink Eye, learn more about the Lost Pier. Once you have the eye, you have to go to Delta Labs. You can find the entrance in m3_habitation_lab_01 or m3_habitation_lab_03 (You can see the name of the room you're in with F5). Once you make it any of the rooms, follow the images below and the instructions.

m3_habitation_lab_01: The first thing you see is a straight path with a right you can take. Go straight, and when you look up you will see a diamond shaped room. Go to the vent in the very very top of the diamond room, and progress from there. The top of the diamond room leads you to an upwards vent with pitons, keep going up that until you find ANOTHER diamond room, and in that diamond room there is a vent hole you have to teleport into with a blink eye.

m3_habitation_lab_03: The start of the room is a single straight path which leads to a diamond shaped room. Go to the very top of that diamond room. In there, there are two paths you can take. One makes you go down, one is a ladder. Take the ladder path, and keep climbing until you reach the top of the ladder. There are two places you can go at the top of the ladder, forward, or backwards. Go backwards, the way the 3rd picture is facing. Backwards leads you straight to another ladder. Climb that ladder, and when you're climbing up, right before the very top of the ladder, there is a vent in the side of the wall. Go in that vent, and you will find the entrance somewhere at the wall.

THERE ARE NEW LADDER ENTRANCES IN THE NEW HABITATION LEVELS, WATCH THIS VIDEO

In the ladder, you will need items that boost you, like rebar and flare guns or perks or anything else if you're not good at making jumps. If you're on endless, you can stack up a lot of perks and become very powerful. There are parts where you have to make jumps, some which you cannot make without items, which is what you would need perks and items for. Also, keep your flashlight pocketed. It gets DARK. You don't need your hammer unless you want to hammer some pitons. I recommend playing with brightness 2.

Alright, you're here now. Just get used to a cycle of juggling the ladder while moving up and you won't lose stamina. What I do, is I grab the ladder with one hand, IMMEDIATELY flick upwards while sprint climbing upwards, let go for a little bit, flick to the ladder, grab the ladder with the other hand, immediately flick upwards while sprint climbing upwards, let go for a little bit, repeat. If you are getting low on stamina, increase the time where you aren't letting go by a handful of milliseconds or something. You should be moving at a decent speed while not running out of stamina quickly, and if it's dark you can fit a flashlight crank in this cycle. This may sound confusing, and you can watch my video guide to see it in action. You also don't have to follow my method.

On your climb, you will find checkpoints for different regions. There are 4 different regions, each with a different environment. The clean region is the first one. It ends after the first expedition cache, which is a platform with loot you will find. The second region is the decrepit region, which has the ladder make twists and turns, and makes the environment darker. The third region, the corrupted region, starts at the second expedition cache. The corrupted region makes you jump from one wall to the other. Then, the 4th region starts with a little platform you can jump on in the wall. It soon devolves into the void.
In the void, that weird nightmare ahead of you is not harmless anymore. If you fall 25 meters, you will die.
After the void, you will see a ceiling, and a little hole. Be careful in the hole, it is covered by a physics object. Go through it, and you get The Ladder achievement. You can keep going from here if you want, or escape through a vent in the wall.

If you want to practice, you can use the loadlevels command. This is a good, short, ladder level command I've set up. If it does not work, restart your game and try again.
loadlevels m3_habitation_ladderwarp_intro m3_habitation_ladderwarp_clean_01 m3_habitation_ladderwarp_500m_01 m3_habitation_ladderwarp_decrepit_01 m3_habitation_ladderwarp_1000m_01 m3_habitation_ladderwarp_corrupted_01 m3_habitation_ladderwarp_corrupted_02 m3_habitation_ladderwarp_corrupted_03 m3_habitation_ladderwarp_1500m_01 m3_habitation_ladderwarp_void_01 m3_habitation_ladderwarp_void_02 m3_habitation_ladderwarp_void_03 m3_habitation_ladderwarp_void_04 m3_habitation_ladderwarp_void_05 m3_habitation_ladderwarp_void_06 m3_habitation_ladderwarp_loop

The intro level is important. If you have the intro level loaded, using a cheat will... do something that happens in the normal ladder too. Something interesting. Having the intro level loaded is also the only way Nightmare can spawn.

Reach Pipeworks. Pipeworks is at 600 meters, and can be found after Interlude Lockdown in the campaign. Once you reach Interlude Lockdown, it will indicate it on your screen, and you'll be in a big circular room with giant yellow text on the wall that says "HABITATION." Continue through the room, and then press the button on the wall next to the elevator. After you jump to the other side of the broken elevator shaft, and you've reached Pipeworks!

Beat the demo. After climbing Pipeworks far enough in the campaign, you will reach Interlude Ascent at 1200 meters. Don't waste any time here, because the mass is NOT waiting at this part. Go to the elevator, and press the button. You can climb on top of the elevator if you want. The elevator will go up, but the announcements say you need to deactivate three elevator security locks.

The mass is kind of fast here, but you can do it quick by saving up 4 (or 2 if you're good at the game) rebars of any type for this. Use 2 Rebars to boost to the platform under the yellow box, and 2 Rebars to go back. This method is pretty difficult though, so if you don't want to do that, you'll need to have a Rebar Rope saved. When going on the path that is accessible without items, you'll get to a part where there is a 4 tile platform a Rebar on the wall near some triangular sort of part sticking out in between a 4 tile platform identical to the one you're standing on. Put a Rebar Rope on that part, and swing on it to the identical 4 tile platform on the other side, and keep going. When you get in the yellow box, press the button, run back to the elevator, and press the elevator button, or wait for the timer. You've beat the demo.

Loop back to Silos in Endless. This is very easy. Essentially, you're just playing up until you beat the game but in Endless. Endless in the demo just contains Silos and Pipeworks, so it is pretty easy.
A connection between Pipeworks and Silos.
You will get climb 1k meters and any lower achievements by beating the demo, leaving 2k meters, 5k meters, and 10k meters. You need to play any endless mode for these last two. The Mass caps at 2 meters per second in endless mode, however endless is harder in the demo without perks.
This is you by 10k meters

Die to a fan in Air Exchange. Air Exchange is one of the sub-regions in Silos. It indicates you are in Air Exchange by the white text that appears on your screen telling you where you are. Touch a fan, and you'll get the achievement. Starting the campaign makes you start with Deep Storage, so start an Endless game and restart until you start with Air Exchange.

Get eaten by a Barnacle. You can find Barnacles very easily by starting a campaign in silos. Barnacles are incredibly abundant in Pipeworks too. To die to a Barnacle, let its tentacle grab you, and don't break the tentacle, and let go of everything. If it is grabbing you and you are close enough to it, it starts eating you. Then you die and get the achievement. Start Endless Pipeworks if it is available, or campaign, and keep going until you hear or see a Barnacle to get the achievement easily.
A Barnacle.
Get Crushed. You will find crush-spike thingies in the Shattered Chambers sub-region of Silos. Wait for it to crush you, and you get the achievement. Start Endless and restart until you get Shattered Chambers. If you know the rooms with the crush thingies, restart until you get one of the rooms in Shattered Chambers that have the crush things.

Place 100 navigational tools. This includes pitons, auto pitons, Rebars, and Rope Rebars. You can check progress in the Logbook by adding the total amount of these items used.
The items that count towards Pathfinder.
Place 100 pitons. Pitons are rather common, and you don't even have to hammer in the piton to count towards the achievement. Auto pitons might possibly be counted for this achievement, but I'm not sure. You can grind this easily by starting a campaign, using the piton on the floor, and restarting. You can check progress in the Logbook.
Exactly 100 pitons.
Throw 100 Rebar Rods. This is basically the same as construction worker, except with Rebar. Any type of Rebar counts, which makes this easier. You can grind this easily by starting a campaign, using the Rebar on the floor, and restarting. You can check progress in the Logbook.
Exactly 100 Rebar. I would've put in the picture with 100 thrown Rebar, but this looks prettier.
Commit 50 crimes. Smash 50 total grub. Smashing grub allows you to grab onto anything for a short period of time. You can find grub easily by finding them at secret locations. Grub is very abundant at secret locations, and if you want to know where secret locations are, I recommend this channel. They have uploaded multiple videos with secret rooms in the demo and the full game (among some other content) and most, if not all of the secret areas have grub in them. If you find a better resource for secret rooms, tell me. When you use 2 grub you unlock grub in the vending machines, which is pretty helpful. They cost 7 roaches at vending machines. Something you should consider, is if you have a grub and want to use it, put it in a pocket, and if you're about to die, use it out of panic. DO NOT underestimate how safe you are. There has been at least 3 times where I don't use it immediately when I'm about to die, and then I die without using it, and possible achievement progress goes down the drain. You can check progress in the Logbook, by looking at the "Crimes Committed" counter. Also, I noticed that when I did this achievement in the main game, it gave me it in the demo too.
A considerably large amount of grub.
Carry a grub up 500 meters, without removing it from your hand. This is very difficult. Conserving stamina with one hand is undoubtedly hard. I recommend doing this achievement early in campaign or endless. Also, if you use any computer, the grub goes out of your hand. I learnt this the hard way. You can use vending machines, but don't go on any of the computers. There are many rooms in Deep Storage that have an easy early grub location. Whenever I manage to get a screenshot of those locations, I will add the grub screenshots here.
Grub Location 1. This room can be found once you have a certain silos unlock in the logbook, I am unaware of which one though.

Grub Location 2. You can find this in the room with the big cylinder in the center.
Probably not. Launch yourself using Explosive Rebar. Explosive Rebar can be found in some secret rooms, easy to access spots, or rarely right in front of you at the floor in one of the Pipeworks Drainage System rooms. Use the Explosive Rebar at your feet, and you get launched really high for the achievement.
Flew away so hard I can see the spritesheet...
Bank 50 Roaches for Middle Class, 100 for High Paying Job, and 500 for Too Big to Fail. This is very grindy. You can bank roaches by picking them up, and using them at the roach hole in any vending machine. You can only pick up gold roaches and platinum roaches. Gold roaches are golden and shiny, and are worth 1 roach when you bank it at a vending machine. Platinum roaches are platinum and very shiny and sparkly, and are worth 5 roaches when you bank it at a vending machine. Platinum roaches are rare at the start, but are very common later in the game. You don't have to take my advice, but this is what I feel is the most useful strategy you should do immediately. For the rest of the time you play this game, focus on roaches. Drop things in your inventory if you need space, just focus only on roaches. One time I had like 15 roaches in my inventory, including some platinum ones, but I had almost no items, yet I was able to bank it all and get a lot of money. Focusing on roaches can really help in the long run. You can check progress in the Logbook. Something VERY important you need to know, is that the achievement only counts current roaches banked. It does not count the full total. Also, I noticed that when I did this achievement in the main game, it gave me it in the demo too.
500 roaches banked.

Forgot your keys. The easiest achievement in the game. Start the campaign and you'll be put in Silos. There is a door that closes and it connects each room to eachother. If you go above the door, it will start to close. If the door finishes closing on you, you die, but if you go under the door before it closes, you'll be trapped in the room, and you'll get the achievement while also noticing that the mass actually catches up for every room passed.
The door to the first room shuts and soft-locks your run.
Fall 50 Meters. This is very easy. If you press F3 on your keyboard, it will show you the ascent you are at which can make this effortless. It doesn't matter if you fall to the floor or get consumed by the mass, as long as its 50 meters in one fall you get the achievement.
Climbgirl falling from a concerning height.
Somebody else has been here. You can either get this by normally progressing very rarely if you get the Silos room that has the art right there in the main climbing route, or you can go in a secret room. If you want to know where secret rooms are, I recommend this channel. They upload videos with secret rooms in the demo (along with some other content) and if you go in any of those secret rooms with art on the wall, you'll get the achievement.
The rare art you can find without straying from the main path.
Smash 100 Roaches. You can smash any roach, however, I don't recommend smashing gold or platinum roaches because you can bank those at vending machines to buy things. If you collide with an area a roach is at, you'll smash it.
They don't suspect a THING.
Pet a Strider. Striders are completely harmless and invincible creatures that can be found in Pipeworks Waste Heap. You can climb anywhere on a Strider, except some weird little small dinosaur hands on it or something. If you repeatedly click anywhere that isn't it's legs, such as its shell or mouth, you will get the achievement for petting it, and the Strider reacts a little bit to your kindness. Also, it's name is Henry.
A Strider.
Bounce off a gasbag. Gasbags are blimp-looking floating creatures that appear in the Pipeworks Waste Heap. They fly around slowly, and if you are near them they slowly chase you. If you touch them, they explode and push you away hard and do a tiny bit of damage, but if you jump on top of them, you bounce off of them really high, and get the badge.
