Please note that this guide contains major spoilers for Dead Cells, including final bosses, biomes and hidden achievements. This guide contains NO spoiler tags at all and contains various screenshots of the biomes and final bosses. This guide was created during the first beta branch and includes the following updates;

• The Elemental Update
  
• Hello Darkness, My Old Friend...
  
• Who's your daily?
  
• The Brutal Update
  
• The Foundry Update
  
• The King's Hand
  
• The Baguette Update
  
• Rise of the Giant
  
• The Bad Seed

If and when further content is released, I will try and keep the guide up-to-date.

I would strongly recommend throwing a few hours into the game and completing the game at-least once before cleaning up the remaining achievements.

If, however, you are struggling or just don't care about spoliers, then proceed!
I've grouped the achievements into categories and split the guide up accordingly. Unfortunately, Valve has a character limit on each guide section. So I've now added extra categories (seemily unnecessarily) so I do apologise!

This guide is currently incomplete!

I've not played the game in a while and very rarely get time to. I've added 'Rise of the Giant' achievements in but haven't done them myself yet so I do not have screenshots or really much information. If you have any screenshots, information, useful tips or spot any errors, please let me know.

Knowledge of Biome Structure

More than likely, you haven't come to this guide having clocked a single hour in the game, wanting to unlock all the achievements. So you probably have all the runes absorbed and know the paths to access the respective biomes. Granted, those who've played since the beginning of the beta branch (like myself), will know that the biome structure has changed drastically throughout the major updates. Hopefully it'll settle for a while now in the 1.0 release, but just in-case, you can view a table of the biomes and their details over at the Dead Cells Gamepedia page here.[deadcells.gamepedia.com]

Another one for long term beta branch players. The bosses have since been renamed, just in-case you've come back from a break and nothing makes any sense.

The Incomplete One > The Janitor > The Concierge

The Watcher > Conjunctivitus

The Assassin > The Time Keeper

The Kings Hand > The Hand of the King

There are currently 5 runes in Dead Cells that unlock permanant abilities (As of The Brutal Update). They are unlocked by killing their respective Elite Guardians.


[1] The Vine Rune is unlocked by killing the Undead Archer in the Promenade of the Condemned. He can be found in a room towards the right side of the map by entering the door at the base of a large overhang. Collecting this rune grants you the ability to permanently grow vines from the ground where possible, allowing you to access the Toxic Sewers and the Old Sewers.


[2] The Teleportation Rune is unlocked by killing the Slasher in the Toxic Sewers. It can be found in a room in which you need to operate a switch to enter. Collecting this rune grants you the ability to permanently teleport between mummy statues when you rub them, allowing you to access the Ossuary and the Prison Depths.



[3] The Challenger Rune is unlocked by killing The Incomplete One at The Black Bridge. Collecting the rune grants you the ability to permanently access the Daily Run door in the Prisoners Cells

[4] The Spider Rune is unlocked by killing The Elite Orb Caster in The Slumbering Sanctuary. Collecting this rune grants the ability to permanently climb walls in order to access particular routes that would otherwise be impossible.


[5] The Belier's Rune is unlocked by killing the Elite Slasher in the special room within the Ossuary. Collecting this rune gives you the ability to permanently destroy the ground by smashing into it whenever you see this runes icon.

[1] The first 4 Boss Source Cells are unlocked by defeating The Hand of the King in the The Castle .



[2] You MUST have the first Boss Source Cell injected for the second one and third ones to drop.



[3] For the third, YOU MUST have two Boss Source Cells injected for it to drop.


[4] The fourth boss source cell is dropped by The Kings Hand in The Castle. As you may have guessed, you need three Boss Source Cells Inject in order for it to drop.


[5] The fifth cell is dropped by The Giant when you have 4 cells active.

A Biome in Dead Cells is essentially a floor. Each floor has a unique design and brings it's own set of enemies. There are achievements for accessing 24 of these biomes.


These achievements are unlocked by simply entering the biomes. You will most likely unlock these are you progress through the game naturally.

There are currently seven bosses in Dead Cells;

• The Concierge
  
• Conjunctivitus
  
• The Time Keeper
  
• The Hand of the King
  
• The Giant
  
• The Collector
  
• Mama Tick

  [1] The Concierge can be found at The Black Bridge. It can be accessed from the Old Sewers, The Prison Depths or the Ramparts. The first time you defeat the Incomplete One you will unlock 'The Fat and the Furious'. Destroying him without taking any damage will unlock 'Steamrolled.'.
  
  
  [2] Conjunctivitus can be found in The Insufferable Crypt which is accessed from the Graveyard. The first time you defeat The Watcher you will unlock 'You've got something in your eye.'. Destroying him without taking damage will unlock 'Flawless Victory'.
  
  
  [3] The Time Keeper can be found in the Clock Room which is accessed from the Clock Tower . Killing him for the first time will unlock 'Blade Master', while doing so without taking damage will unlock 'The Dance'.
  
  
  [4] The Hand of the King can be found in The Castle . Killing him for the first time will unlock 'The last rampart falls...', while doing so without taking damage will unlock ' Do you need.... a hand?? Bahaha!'.
  
  
  [5] Kill The Giant
  
  
  Kill The Collector
  

[1] 'They came from behind!' can be unlocked by killing yourself with an elevator. Find any elevator, drop down under it, call it, and stand directly underneath. As it hits you it will deal damage and may need to be done multiple times to kill yourself.


[2] 'Ohhhhhh! That hurt!' can be unlocked by dieing when you are holding 100 cells or greater . To do this, simply play through a run as normal, but destroy the door by The Collecter to proceed without giving him your cells. Once I got to >100, I kept giving him cells until I rounded it back off to 100 (there's no need to waste cells unecessarily).


[3] 'YOLO! Or not?' can be unlocked by activating the mutation 'Ygdar Orus Li Ox!' which abbreviates to 'Y.O.L.O playing on the phrase 'You Only Live Once'. Ironically, it brings you back to life once when you die. Simply activate it, deplete all your health, and the item will activate causing the achievement to pop.



[4] 'We've all been there before...' is unlocked by simply diving into spikes. If you don't know how to dive, hold 's' to crouch and then press space while in the air (At least on keyboard). Simply do this over spikes, and take the damage.

[1] 'Slash! Slash! Roll!' and 'Pimp my ride.' can be unlocked by collecting 10 weapon and active skill blueprints, respectively. Blueprints are dropped by specific enemies throughout the game. The following guide created by Steam user @LootZ shows the locations of all blueprints.

https://steamoss.com/sharedfiles/filedetails/?id=943412533


[2] 'Please stand clear of the doors! can be unlocked by killing an enemy with an elevator. Now the elevators at the end of biomes tend not to have enemies near them. So, the best thing to do is wait until you come across an elevator in the middle of a level and try and lure a flying enemy near it, like a bat. Then simply keep toggling the elevator until you smash into it and kill it.


[3] 'You are absolved of your sins child.' can be unlocked by being cursed and then killing the necessary enemies without being hit, in order to lift the curse. Curses can be obtained by opening cursed chests or by breaking down a golden door for free, that would usually require gold. I personally have only ever had to kill 10 enemies to lift the curse. However, I have heard up to 40 is possible. To make this easier, there is a mutation (Alienation?) that halves this number.


[4] 'You've got nothing, elites!' can be unlocked by killing 100 elite enemies. Elite enemies can be found in room with a large stone slab and a red symbol that glows upon entering. Simply grind away at the game until you slay 100 of them!


[5] 'Speedy Gonzales!' is unlocked by successfully reaching a timed door in time, and entering it. Timed door can be found on certain biomes such as 'The Promenade of the Condemned', 'The Ossuary', 'The Old Sewers', 'The Fog Fjord', 'The Black Bridge - Collector'.


[6] 'See, that wasn't so hard now, was it?' is unlocked by successfully completing a challenge/secret room. Challenge rooms are found by activating runes found on the floor. They will spawn a blue portal in which you can enter by interacting with it.


[7] 'Through the looking glass' is unlocked by finding a secret area during a playthrough. One of the secrets is in 'The Promenade of the Condemned' biome and can be found immediately above the spawn area. Another one is in the Prisoner's Cells. It can be found before the spawn area behind a hidden wall and contains the Quick Bow Blueprint. You can simply go back to the area if you've already uncovered the blueprint before the update.


[8] 'Harder, better, faster, stronger!' is unlocked by successfully completing a daily run. The daily run can be accessed from the main menu and you must kill the boss and finish the run to unlock the achievement.


[9] 'What? There's nothing wrong with these...' is unlocked by finishing the game (Killing The Assassin) while holding either the starter sword, bow or shield. As of the brutal update, they can be found in the starting area in The Prisoners Cells, inside wall runes.

[1] Finish the game, by beating The Hand of the King while still having the Y.O.L.O mutation active (without dieing and being brought back to life).



[2] This is a difficult one. Do what it says on the tin. You've gotta beat the final boss, The Hand of the King to finish the game. But, you've gotta do it while holding the Cursed Sword. If you don't know, this is sword with relatively high DPS, but you die after a single hit when holding it. Fortunately, this does mean you can purchase the sword immediately before the final fight, then nuke The Hand of the King if you have the means to do so. See the below in-depth guide created by Steam user Ezergile .
http://steamoss.com/sharedfiles/filedetails/?id=1257699517


[3] [4] [5] [6] These 4 achievements are unlocked for beating the game with one, two, three and four Boss Sources Cells equiped respectively. If you don't have these yet, or know what they are, see the 'Source Cell Achievements' section above. Having the cells equiped does give the bosses a higher DMG stat, so good luck!

You can innaculate your Boss Source Cells at the start of the Prisoners Cells biome below the jars.


[7] Beat Mama Tick while still having the Mushroom Boi in your possesion.

[8] The ritual can be initiated by taking the Mushroom Boi to the Morass of the Banished biome and sacrifice it to the altar. This will skip the final fight that would usually take place in the Nest.

[9] I believe this unlocked at the same time as number 8 when sacrificing the Mushroom Boi.

That's all the achievements as of 21st July 2029. As previously mentioned I will update the guide as soon as possible if more achievements are added in future updates.

Here's a link to another guide I made before-hand which shows just the 29 hidden achievements (If that's what you were after).

If you liked this guide please give it a thumbs up, otherwise please comment and let me know how I can improve it.

Found an easy or better way to get an achievement? Please share how in the comments and I'll add it this section, it may help others!

For 'Please stand clear of the doors!'...

"My method for achieving the elevator one involved the Ossuary. At the top of the elevator, I lured one of the green skeleton enemies to the elevator and made it go down, where I jumped off to the side while it was going down. Luckily for me, the elevator was on a small platform, so the enemy had nowhere to go from there. Then when it stepped off on to the platform, I sent it back up.

Took me a couple tries, but I forced the enemy into a windup attack animation, the regular swing and not the pounce, after I called it down so it would delay them enough for the elevator to crush them. I laughed harder than I probably should have when the elevator crushed it and the achievement popped up."

I found an easy way to get the "Please stand clear of the doors!" achievement. What I did was get a swarm of biters and got them crushed by the elevator.

At the end of the Promenade of the Condemned, there's another easy-ish way to get "Please stand clear of the doors!" - You can bait a Phazer into following you right up to that point. Activate the elevator, jump off, then once the Phazer is under it, call the elevator back down and just block its attacks until you have a Phazer Pancake.

For What? There's nothing wrong with these...

Steam user Silejonu confirmed that;

"I can confirm that you indeed need to kill the Assassin to get "What? There's nothing wrong with these...". I just got it with the starter shield. Note that you get the achievement when you go through the pipe that kills you at the end of the game, not when you beat the final boss."

For I like to live dangerously...

"Seems like "I like to live dangerously" should be a cake walk to get...
Just wait to buy the sword until after defeating the assassin... am I missing something?" -He confirmed that you do not get the achievement via this method.

For Do you need.... a hand?? Bahaha!...

Steam user Terminus_X said;

Originally posted by Terminus_X:

"For anyone still trying, the "Do you need a hand?" achievement can be fairly easily obtained in tandom with the "I like to live dangerously". Assuming you have at least lv2 healing potions and access to a number of weapons, merely play through a normal run, preferably going through the prison depths and the ossary to grind for extra scrolls, and stack up on either tactics or brutality. When you get to the Castle, slaughter everything in sight then collect two tonics (modifiers immaterial) and a cursed sword from the shops/drops available (randomise helps). At this stage, you should have between 20-25 of your chosen scroll and at least a cursed sword+.

Once in the fight, wait for the Hand to approach for a second, then activate your first tonic and go to town. You should be able to force him into his first enemy 'interlude' fairly quickly. Use the other tonic to kill any of the threatening enemies, find a moment to take a health potion and restock your tonics, then kill any remaining enemies and repeat. He was dead within about thirty-fourty seconds. I have a screenshot somewhere on my profile with the build I used. Hope this helps!
