Note:
With the updates, you now require 5 runs for the 100%. You need to:

4 - Start a NG+ from your Maximum Security run to upgrade all weapons and items. Set the difficulty to Minimum Security and kill and collect everything.
5 - Beat the game in Contagion Mode deathless. Do this with your NG+ Minimum Security run so you can practice each chapter. Do a chapter in Normal Mode then do it in Contagion Mode. I provide more detail below under the "You Belong Here" achievement.

Difficulty Achievements

The Protocol is About Life
Beat the game on Maximum Security difficulty


When starting a new save, choose the Maximum Security difficulty and complete the game without changing the difficulty.

Recidivist
Finish Game in Hardcore Mode


When starting a new save, choose Hardcore Mode and complete the game without changing the difficulty.

Lifer
Finish Game in Hardcore Mode NG+


Beat the game in Hardcore Mode and then complete it again.

Parole Denied
Finish New Game Plus Mode


Stack this with your Hardcore NG+ run.

Glutton for Punishment
Finish Game in Contagion Mode


When starting a new save, choose Contagion Mode and complete the game.

You Belong Here
Finish Game in Contagion Mode Without Dying


When starting a new save, choose Contagion Mode and complete the game without dying. Easily the most difficult achievement in this game. 

A few things you want to do:
- Turn off cloud saves for The Callisto Protocol and keep a backup of your save to revert to if you die. Right click The Callisto Protocol in your Steam Library > go to "Properties" > turn off cloud saving.

- Your save can be found here: C:/Users/”Username”/Appdata/Local/CallistoProtocol/Saved. Copy the entire content of this folder to a new folder and save it on your desktop after each chapter. If you die, replace the save with the back up on your desktop. Don't feel bad about doing this. You already need 5 miserably long runs to 100% this game. Don't make it 6+.

- Do your Contagion Mode run alongside your NG+ Minimum Security run to practice each chapter. A few areas you want to practice are: The trap in Chapter 2 (know where each of the 3 enemies spawn so they don't push you into the trap), The Security Bots (they only take 4-5 shots to kill but will one hit you), the water slide in Chapter 3 (the fans will end your run), the fall after the ship is shot down in Chapter 4, and Two-Head (it can one hit you).

Here is a run by the popular Youtuber, CarcinogenSDA, of a no damage Maximum Security run. You can follow along and see how he handles each situation. Keep in mind he will have more credits available because Maximum Security is easier than Contagion Mode. https://www.youtube.com/watch?v=aI30iVavBsc&ab_channel=CarcinogenSDA

Riot Mode Achievements

Instigator
Complete Riot Mode for the first time


Just play Riot Mode and complete a run of any length.

Big Game Hunter
Complete Wave 50


Riot Mode is set to the easiest difficulty. It's fairly difficult to die and you also unlock upgrades you can activate at the start of a run based on your highest score ever. So even if you don't make it to wave 50 during your first run, subsequent runs will be easier.

Big Spender
Spend 20,000 Credits


You'll get well over 50,000 credits going to wave 50. Completing the bonus objective that refunds your next 3 purchases is a good way to get this early. You can purchase weapon upgrades which can be upwards of 5,000 credits each for free.

I am the Danger
Dismember 100 limbs in Riot Mode


Upgrade your baton early and melee enemies often. The melee is really powerful in this mode because the difficulty is so low.

Bear Trap
Kill a Two-Head with a Hazard


Two-Heads spawn every 10 waves. In order to activate a trap, you need to purchase a fuse switch. Multiple can be owned at once.

Hoard Mode
Survive five consecutive waves without spending any Credits


This is easy to complete early as there are fewer enemies. You can also go five waves without purchases at later waves once you have a good stockpile of supplies.

Subject Alpha
Use the Power-up 10 times


Use rampage mode 10 times during your run. The meter will fill every couple of waves by defeating enemies.

DLC: Final Transmission Achievements

Keep Fighting
Killed your first Biobot!


Cannot be missed.

It's Time
Obtain the Kinetic Hammer


Cannot be missed.

One Last Job
Finish Final Transmission


Cannot be missed.

Quick Pick
Solve any Security Lock System in less than 7 seconds


Go to: Options > Accesibility > Combat Assists. Turn on QTE Single Press and QTE Auto Complete. Puzzles will now automatically complete and give the achievement. The first chance you have to complete this is after making it to the doctor's lab.

This Isn't About Escape
Locate the Escape Pod


During the objective, "Find a path through the hallway passages.", you'll be walking around in a loop. Continue through the loop until you reach a room with a gate fuse underneath a sign reading "TURN BACK". Take the fuse and turn back. After going through two doors, you'll come to a dead end with two doors and place where you can use the fuse. Go through the door in front of you. The achievement will pop when you reach the escape pod.

There is a chance the achievement will glitch and not unlock. Keep an auto save before this section so you can try it again if you need to.

Don't Let It Mellow
Destroy all Hammer Crates on the Factory Floor


After you unlock the hammer, clear out all the yellow boxes in the room you obtained the hammer, the hallway leading to the factory, and the factory floor.

Information Overload
Find all 8 Protocol Data Drives


1 - On the table after the cutscene with Caitlyn at the start of the DLC.

2 - Remove the fuse on the lower level of the main cell block and use it to enter disciplinary confinement. The data is to your right. You need to go around the room to reach it.

3 - After making it through the vent and dropping down the hole, restore power to the door near you. With your back to the door, walk forward and take the door to your right. Continue down the path and activate both switches to restore power. Backtrack to the door and enter it. Then take the door to your left and enter the hole. The data is in bunker at the end.

4 - Back towards the switches you activated to restore power is a crevice you can enter. Pass through it and take the door to your right. Take the following door to your right and the data is in the room next to the security bot.

5 - Past the door to your left after climbing up the ladder leading out of the waste water. The data is on a biohazard container to your right.

6 - You'll see some security bots moving across a conveyor after solving the 2nd security lock. The data is to the left near the reforger.

7 - After the vent section with traps, take the door opposite from where you land. Proceed down the path and open the door to your left using your shiv. Enter the room to your left and pick up the fuse. Exit the room and take a left. Proceed down the hallway and use the fuse to unlock the last door on your left. The data is in that room.

8 - After taking the elevator and being tasked with finding 3 fuses, break the yellow crates next to the reforger. The data is to your left behind some crates.

Thank you

Higher difficulties have reduced credit drops and enemy drops are also random. So you could do everything exactly the same and still be short a few credits because of bad luck. The linked video is only on Hardcore Mode and not Contagion Mode.

Upgrades carry over to NG+ so bad luck won't lock you out from getting an achievement.

[AIRY.VOID]

I watched the video with walkthrough but i didn't get how he could buy the final riot gun upgrade because he already bought the second upgrade for the force glove. I've done everything but still can't realize where i can find 2700 callisto credits. It looks like unfair play with hacks because i have only 900 credits at the same time and place like on video.

[G]

The achievement can bug out for some people. Check out this thread for some possible fixes.

https://www.reddit.com/r/TheCallistoProtocol/comments/171hgt2/you_need_a_gun_trophy_bugpossible_fix/

[optifine user]

"you need a gun" is bugged? just got the pistol fully upgraded and didnt get the achivement. Anyone got a fix?

[G]

Thanks for the correction! I got this while playing and thought it was unmissable. I'll fix it right now!

[wXzu]

This Isn't About Escape is missable. If you turn back in the loop section before finding the fuse, you will miss the achievement.

[shade00]

maybe its been changed but i was waiting each ten rounds did not see them every ten rounds

Just a quick update:

11 of the bio logs were moved so I updated that section. I added the locations of weapon schematics too so you can get them as you collect logs. I also added all of the recently added achievements. I just have a few more logs to update for the DLC and the guide will be 100% complete . . . again.
