This is the updated guide from the guide that was created for the older versions: here

Project Brutality (GZDoom)

1. Have Doom purchased through Steam.
   
2. Download the latest version of Project Brutality (currently 3.0)
   
3. Download the latest version of GZDoom (currently 4.5.0)
   
4. Install Doom then locate the folder in explorer (Steam/steamapps/common/(Doom)
   
5. Open the GZDoom 7zip file you downloaded [e.g. gzdoom-4-5-0-Windows-64bit.zip]
   
6. Open /base folder (if you are in the Master Levels of Doom folder you will not see a /base folder. That's ok, just apply the following steps below in that folder -- as if you are treating it like it's a /base folder)
   
7. Copy all files from the GZDoom zip folder to your Steam Doom /base folder
   
8. Delete dosbox.exe, then rename gzdoom.exe to dosbox.exe
   
9. Go to the GitHub Repository for Project Brutality 3.0 in the "Getting Started" Section
   
10. Click on the Green Button that is labeled as "Code"
    
11. Download as ZIP
    
12. Once downloaded, rename "Project_Brutality-master.zip to "Project_Brutality-master.pk3 (it's important that you have File Name Extensions checked; in File Explorer, click the Ribbon dropdown > Go To View tab > Under Show/hide section > Make sure the "File Name Extentions" checkbox is enabled/checked)
    
13. Copy/Move "Project_Brutality-master.pk3 over to the '/base' folder located within the doom steam folder
    
14. Run the game once to have the gzdoom-(YourPCUserNameHere).ini created automatically.
    
15. Open the 'gzdoom-(YourPCUserNameHere).ini' and scroll down to where you see [doom.Autoload]
    *NOTE: If the .ini file is not in this folder once you have launched the dosbox version of GZDoom, then it might be located in the following path: Documents»My Games»GZDoom. It may simply be named: gzdoom.ini (without your username).
    
16. Type or Copy/Paste Path=Project_Brutality-master.pk3 right under [doom.Autoload] or [doom.id.doom2.Autoload] if the autoload doesn't work for doom
    
17. Rinse and repeat for however many Doom games you want to apply this to (The Ulitmate Doom, Doom II, Final Doom, and Master Levels of Doom)
    
18. "Play" Doom through Steam and you will have Brutal Doom automatically loaded
    
19. Enjoy

* - note (again) that you will need to run either Brutal Doom or Project Brutality, you cannot run both otherwise you will come across crashes

@Ukdesigner, you are commenting on the DOOM II guide. I make note of all this in the DOOM (Ultimate) now known as DOOM + DOOM II version. Please see that guide and follow it.

[Ukdesigner]

Latest version of Doom on Steam is called Doom Ultimate which has a very different file structure with DOSBox in separate folder. Can't get brutal working on this version :(

[Underqualified Gunman]

it does just needs your launcher for doom mods be set to the unity doom .exe

[Slender]

THANK YOU FOR THIS, I could not for the life of me find the .ini file until i saw this post so thank you for making this

[Simbolion]

No problem at all

[slyfuldragon]

I've had a friend mention this to me as well but I never updated the guide because I couldn't validate it myself.
Thanks for the reminder to update it anyway. I'm sure this will certainly help.

Hi everyone. For those looking for the .ini file but can't find it anywhere, try going to Documents»My Games»GZDoom. It's the only file there and it should be named gzdoom.ini. Just open that bad boy up and follow as instructed (this took me WAY too long to find -.-)

[slyfuldragon]

Keep in mind with the newer Doom update, it gives you an option to launch DOS or DOOM through Steam. Seems like a dumb statement to point out, but it can get the best of us; just make sure to select the DOS version through steam if you want to run modded/gzDoom through instead of updated vanilla Doom

[BloodyCrow]

It didn't work, but I'm going to learn more about doom modding in general because this oddly inspired me to look into it

[slyfuldragon]

Awesome! Sounds good!
