Thief - Achievement Guide

A complete guide to get all achievements on Thief.

-Disclaimer-

This guide is considered complete, only the collectable exact location are not listed but you are welcome to make a comment so I'll add them on each of the chapters.

Playthrough 1

You will most likely need at least 2 playthroughs to get all achievement except one which will require to finish a challenge map with an epic score.

Playthrough 1

Enjoy the game in whatever difficulty you want, and focus on getting everything you can.
You can also try to get achievement prior to playthrough 2 but in your second playthrough you will only do the main objectives and therefore it will be easier.

Focus on the following :
Obsessive Compulsive
Stole all loot and collectibles in a single chapter.
Sleight of Hand
Picked 100 pockets in a single playthrough
Working Overtime
Completed all client jobs in The City
Dastardly Deeds
Completed all Basso Jobs in The City
Finders Keepers
Discovered all secret areas
Cache Dispenser
Used 40,000 gold
Predatory Drive
Finished the game in 15 hours or more

Playthrough 2

You will want to stack all these achievements and focus on main objectives only.
You will need to create custom settings of 700 points or higher.
It is best to stack the following one as they are required for both related achivements :
No focus (50 pts)
No kills or Knockouts (170 pts)

Custom example

Base Difficulty - Master
No focus (50 pts, so you won't require to unbind that key)
Stealth takedowns only (50 pts, since you will try to stack the no kills and no knockout)
Specialty arrows only (50 pts, blunt/water/fire/rope arrow only + flash bomb)
No food or poppies (100 pts, you won't be able to use them only sells them, also your health should replenish between chapters)
Expensive Resources (70 pts, the only thing I bought was all the tools for 2000g)
No upgrades (100 pts, you can still buy your tools)
No kills or knockouts (170 pts, straitghforward)
No alert/b] (170 pts, dogs and birds also count)

The customs settings are explained in the section called Difficulty level selection in the gamepressure guide of Thief.

/!\ If you are not opting for customs settings, you can opt to unbind the key for the focus ability /!\

Focus on the following :
Hard Times
Finished the game on Master difficulty
Something to Prove
Finished the game with a custom difficulty of 700 points or more
Clear Headed
Reached the final chapter without using the focus ability

Challenge mode

Challenge mode

The easiest way to get it is to choose the following challenge :

The related guide and its video can be found on trueachievements regarding the modesty denied achievement.

Replay a mission or client job

Chapter Replay

If you want to restart the chapter you are currently in, you just need to either use the auto-save of the chapter start or choose 'Exit to the city' and then interact again with the Chapter area.
If you want to replay a chapter, you just need to re enter the area that triggered that chapter.
For that I suggest you use one of the following guides :
https://steamcommunity.com/sharedfiles/filedetails/?id=233717834
https://steamcommunity.com/sharedfiles/filedetails/?id=272186385

Client Job

If you want to restart the client job you are currently in, you just need to choose 'Exit to the city' and then interact again with the client job area or maybe you can also use the auto-save to restart at the start of the job.
If you want to replay a client job, you just need to re enter the area that triggered that client job.
For that you might need advance a chapter if you already completed the client job but missed some stuff. Check the two guides above on where to find the area again.

Documents missable (not required)

There are only 206 documents to be found on the 215 listed in the game, also they are not required for any achievement.

Here are the one that are high likely missable :

Prologue- 1 document

Just ensure that you get this entry after finishing the prologue at the start of the game. You found it where you jump from the rooftop to a window in a house, the note is on the table. When you leave the house you hear a woman complaining to a man peeing.

Newspapers- 19 documents

The list come from the following guide and since it is not easy to read I've noted them all below.
The guide is from the forum of psnprofiles that list all the newspapers.

If you want to get all 206 documents, I suggest that you focus on those newspapers as most of them are missable very early.
