The Callisto Protocol has 43 Bios collectibles found throughout the 8 chapters of the game.

This game does not have Chapter Select or New Game +, which means all collectibles in this game are 100% missable. If you miss something, you'll need to either go back using an auto save or manual save, or replay the entire game a second time.

There is also one noted collectible as glitchy, and it should be checked on a few times during chapter 4 to make sure it counts.

Can I replay it on easy just grapping the ones I missed? Or does it work on NG+ only?

By zeno2k on 09 Mar 2023 08:32

For some reason some the collectables don’t appear for me in the positions at all odd

By Baldy89 on 16 Sep 2023 21:10

Both of the locations for The Commonality achievement are shown in the video above! :)

By Maka91 on 03 Dec 2022 21:01

Ahh just watched it, guess I should've watched it before commenting! 😅

By NoFeetPicPls on 03 Dec 2022 21:08

What times? Ugh one is in below and other secret room earlier on. I missed it. I may use this video now.

By A DEAD B0DY MAN on 04 Dec 2022 07:19

So if I start a second playthrough do I have to collect EVERYTHING again or just the ones I missed?

By PH1 HUNG on 04 Dec 2022 09:49

Wanted to do a blind playthrough to enjoy myself and missed a handful through natural exploration. I have zero desire to replay the game again without the upgrades I purchased, so I'll wait till NG+ gets added to go back and finish this out. Will be using the guide when that time arrives, so thanks well in advance!

By Tanooki Sage on 04 Dec 2022 17:16

It's a completely new save, and you have to grab everything again.

By Maka91 on 04 Dec 2022 17:16

This is so infuriating didn’t think this was missable hopefully when they finally add new game+ it will carry

By ArmedGamerbeast on 04 Dec 2022 22:26

Thanks for the great guide, Maka. It may be worth pointing out that in Chapter 4 there is a collectible that can completely wipe if you die after collecting it, so you need to make a manual save before collecting it. It's for Sgt. Pekelo. PowerPyx mentions it here: https://www.powerpyx.com/the-callisto-protocol-chapter-4-hab...

It happened to me and I didn't realize until I was at the very end of the game and the achievement didn't unlock. So frustrating.

By BobLoblaw on 05 Dec 2022 18:54

Great Guide. My achievement glitched like in your Video, i earned it before collecting all Bios.

By Mister Uncut on 06 Dec 2022 13:43

Achievement doesn't glitch. The achievement is for all implant bios, not necessarily all sound files. I missed some sound files on my first playthrough, but I got all implant bios. Collectible #42 is the last implant bio. #43 is a sound file.

By Ryamus on 07 Dec 2022 20:51

I 1000% missed at least two of them but still got it. It's still a bit unclear what it is, but I think Ryamus is right.

By TriggerOfTime on 07 Dec 2022 23:51

I think you have to unlock every category in the bios menu. Basically make sure that every person's name is clickable.

By Maka91 on 08 Dec 2022 06:38

Evidently it is about the peoples' bios (key icon 1/1). Those can be unlocked via picking up Audio Logs or harvesting implants for the first time per subject. Once either are accomplished, relative Data-Bios are unlocked. There are Data-Bios for subjects that have only one data available, to be collected through picking up Audio Logs or harvesting implants, but their Data-Bios' entries are receiving full status (key icon 1/1 with waveform icon 1/1). Conclusively, not all data is necessary to be collected, relatively.

By CyberneticHFX on 13 Dec 2022 03:16

Thank you Maka. Just followed your guide and got the achievement in one run with no problems.

By THEpaynexkiller on 13 Dec 2022 10:06

By BobLoblaw on 14 Dec 2022 18:48

Got my achievement following your guide but did not read any of the bios etc .

By xSAMMY the SEAL on 19 Dec 2022 14:46

Got this on my 2nd play through, with the secret rooms but missing 2 of Mahler’s and and 1 of Cole’s. I did listen to most of them but some I cut off early as I’d heard them on my first run.

By DemonBullets on 29 Dec 2022 15:57

I've had item 20 disappear on two play throughs without dying after getting the item. it would vanish after a few check points for some reason.

By Caboose1132 on 31 Dec 2022 15:07

Just a tip, with New Game + the achievements pops immediatly after picking up any data bios that you missed. I missed one in Chapter 2 and unlocked as soon as I grabbed it.

By vK Knave on 20 Jan 2023 19:52

Thanks for the guide! I don't know how to do videos yet otherwise I'd have started to make one 😅
Are you gonna do a guide for The Commonality? I just unlocked it, and I feel a video guide would be best for it since I believe you have to go to two secret locations for it to unlock.

By NoFeetPicPls on 03 Dec 2022 21:00

Be advised, to understand its save game system: Only the status at incremental checkpoints are mapped towards save game data. That means, even after a manual progression save, its save game data is relative to the last checkpoint's status. Not being aware of that, can eventually translate to unconscious negative events, in worst case scenarios. Focused example: Checkpoint triggered, data was collected, manual save performed, manual save game data loaded (after failure; Load Game/Manual Save #; Restart Checkpoint; Continue). That data is not collected on continued progression like that. Focus on saving status for good by triggering a next checkpoint.

So the embedded video is no longer reliable, and the new text explains a lot of them have been moved since the video was made? Why would the game do that? That sucks.

UPDATE: I found the answer on the official website...
ANSWER,
"In order to maintain The Callisto Protocol's narrative structure and avoid over-lapping audio, some of the in-game audio log locations were moved."

I'm about to start this game. Anyone find a new, updated collectible guide? Or is this the best there is still?

SAVE FILE DISAPPEARED on XBox. Solution.

If you turned off, or restarted, your XBox while playing Callisto Protocol, the last save may not appear at the main menu.

It's still there. Don't worry.

At the Main Menu select:
- New Experience
- Skip cutscenes
- Control Jacob in his ship for a few seconds.
- Hit Start.... NOW
- Select LOAD GAME
- Choose a previous save from your last gaming session.

Thank you E vee dub !

I thought I had lost all progress finding these stupid implant files, plus suffering through fights with no ammo because I sold all ammo to buy upgrades.

Use this same "RELOAD-PREVIOUS-SAVE" technique if you miss a collectible, but your way back gets blocked.

By E vee dub on 02 Apr 2024 20:16

Can confirm with @vK Knave that you only need to collect the collectibles you missed in order to unlock the achievement. However, you still need to figure out what it is you missed in order to get it, game isn’t very good when it comes to the collectible screen.

Hi, this collectible walkthrough has been updated with changes regarding patch 5.02:

https://callisto.sds.com/en-us/news/patch_notes

Some of the collectables have changed locations compared to where they were before. I have updated this accordingly so it's correct.

Chapter 1: Cargo

Chapter 2: Outbreak

Chapter 3: Aftermath

5) A little while later into this chapter you will loot a corpse for a key card to open a door. On the corpse you loot will be the audio log. This is just before you enter the Laundry B202 room. (Same as Before)

6) Just after the previous collectible you will enter the next room and will fight one enemy.

From here walk forward and turn right to go down the stairs. Once at the bottom go to the left side of the room to find the Office B112 room with the collectible on a corpse.

7) From the Laundry B202 room where you just fought the enemy take the left stairs down this time. Run forward to the other side of the room. Open the door on the right side and crawl through the vent.

Once through the vent follow the path down. Once at the bottom turn left and go into the room with all the chairs to find the audio log on the main desk.

8) A little while later you will make your way to Medical Ward C101 where you need to manually open the door with your hands.

Just after this there will be a corpse on the floor with the collectible.

9) A little while later you will have obtained the GRP upgrade and will have opened another door with your bare hands. In this room will be loads of corpses hanging from the ceiling. On the right side of this room behind a bunch of boxes you will find the collectible on the floor.

10) Just after this you will be in a room with a spinning fan.

Turn right and bare left to walk behind the fan to find the audio log on a corpse on the floor.

An enemy will surprise attack you here also so watch out.

11) After regrouping with Elias you will use a gondola to cross a large gap.

In the next room with all the metal structures where you fight a bunch of enemies. Before leaving, climb to the top of the platform to find the audio log on a corpse next to one of the power switches.

12) A little while later you will be in a cutscene where you get locked inside a prison cell. Before leaving the prison cell, from where you are turn around to find the audio log on the table.

Chapter 4: Habitat

Chapter 5: Lost

Chapter 6: Below

Chapter 7: Colony

Chapter 8: Tower

If you prefer a video walkthrough, feel free to use my video as a reference:

Hope this helped, thanks again!

To add insult to my injury, my save game disappeared when I turned my XBox off and lost all progress.
I was on collectible 37 about to start the final chapter.
The game isn't even that good.
I may not bother restarting.

UPDATE:
You can hit start and choose LOAD GAME from a previous save if your way back gets blocked and you missed a collectible.
A hard lesson I learned the hard way.

Achievement unlocked once I picked up #42 after the turrets were disabled. I missed one collectible earlier too.

CONFIRMED: This guide is updated and the best to follow. I followed the text/picture guide, never watched the video.

Thanks.

Thumbs up #18 from me.
