Blade of Agony is a story-driven FPS. The project is inspired by WWII shooters from the 90's and early 2000's, like Wolfenstein 3D, Medal of Honor, and Call of Duty, but with faster-paced gameplay in the spirit of Doom! The game can be played standalone using the GZDoom engine as a base.


It's 1942, and the war approaches its peak. The U.S. has joined the Allied forces, and the Soviets are pushing back the front in the east. The tides of war are turning, and Hitler's victory seems more and more beyond his grasp. But the Nazis, refusing to capitulate, have grown obsessed with human experiments and occult artifacts, in which they see a potential escape from their final Doom. The Allied leaders reject this possibility as nonsense; nonetheless, some still fear what the Führer might be up to. The situation is nebulous, however, and little is certain.

You are Cpt. William "B.J." Blazkowicz, an Allied spy, a fearless risk-taker, and the greatest soldier to ever take up arms in World War II. Your role has changed, though; you've retired from active duty, and now you spearhead operations as a systems analyst. You thought it would be the right choice--leading and motivating instead of doing the dirty work--but lately you've grown restless. At least until a few days ago, when you received an encrypted message from your old friend and comrade Cpt. Douglas Blake, calling you back to duty...


Blade of Agony is much more than just a pastiche of the classic shooters that inspired it; the project will offer a unique experience. It also has many features not often seen in source port projects--Blade of Agony truly pushes GZDoom to its limits.

  • 17 playable and unique levels in Chapter 1 & 2 (over 24 in the full game)
  • Orchestra-quality game music
  • Voice acting and ambient soundscapes
  • A combination of low-poly models and hi-resolution sprite assets to create the perfect retro feeling
  • Devastating armaments from the battlefields of WWII
  • Interactive NPCs that support the twisted plot's progress and help you understand the game
  • Beautiful special effects (weather, elements, explosions, etc.)
  • Much, much more!

F.A.Q. - Frequently Asked Questions

Problems or questions? Take a look at our F.A.Q.! If it doesn't address your issue, join our forum and we will definitely most likely help you in a reasonable time.

Can I support the development?

If you are interested in helping us out, the easiest way to do so is by making pull requests to the project's GitHub repository. The development repo is public, and we are happy to have any kind of help. We can't promise to implement every public change, but we'll have a thorough look at all of them, and we'll be thankful for any helpful improvements or suggestions.

How do I install and play the WolfenDoom snap?

Snap packages can only be installed on GNU/Linux distributions for now.

Most, if not all modern Linux distros support snaps. If you're on a distro that supports snaps, follow the instructions here to set up snapd on your system, and then type

snap install boa

into your terminal emulator of choice to install the WolfenDoom snap on your system.

To play WolfenDoom: Blade of Agony after installing the snap, type

snap run boa

or even just


into your terminal emulator of choice.

The GZDoom build is a custom build based on GZDoom 3.3.0, modified to work in the snap package it is distributed in.

How do I run Blade of Agony?

If you aren't used to the Doom mod mechaniques, simply follow the step-by-step tutorial below to run Blade of Agony:

  • Buy and download Doom 2 (alternatively get Freedom Phase 2), you only need the DOOM2.WAD though
  • Download the latest version of GZDoom (best choice is the latest development build)
  • Download the latest version of Blade of Agony
  • Create a new directory on your computer
  • Copy DOOM2.WAD in the new directory
  • Unzip GZDoom in the new directory
  • Copy the Blade of Agony PK3 in the new directory
  • Drag & Drop the PK3 on GZDOOM.EXE
  • At first startup make sure to define all settings (basic and BOA)
  • Get psyched!

I have massive slowdowns/bad framerate, what can I do?

If you are having issues with slowdowns and a low framerate, there are a few things you can try to improve performance when playing Blade of Agony:

  • if you are using the standalone version, delete the gzdoom.ini file and configure GZDoom manually
  • open the Enhanced Options and lower the various settings
  • open the Options and adjust the Display Options (reducing resolution in particular) and OpenGL preferences (disabling any filtering)

Blade of Agony is very resource-demanding in ways for which the Doom engine wasn't designed. The team has made an effort to optimize the mod as fully as possible without compromising their overall vision, but this project pushes the engine to its absolute limits. If these tips don't solve your issues, you will unfortunately need to play the game on a better hardware setup.

I saw "Doom" - does this require Doom to run?

No! Blade of Agony is entirely standalone, which means it needs no Doom Engine games in order to run! The bundle for your OS of choice is all that you need! Make sure you extract it to a directory that can be written to. Alternatively, you can run the game as a mod version, which requires the appropriate IWAD.

I'm used to Doom's play mechanics. Will I like Blade of Agony?

Blade of Agony is actually based on Doom, but the gameplay is very different. In particular, we've tweaked the mechanics to feel and play more realistically. For example, weapons must be reloaded, you move more slowly, and the Nazis are more dangerous! Be sure to talk to the NPCs for more hints.

My Antivirus program is detecting malware!

WolfenDoom: Blade of Agony does not include any malware. We are investigating this issue. boa_c2.exe is a batch script wrapped in an executable file. This batch script starts GZDoom, loading the WolfenDoom: Blade of Agony package as a PWAD.

If this bothers you so much, just drag and drop the boa_c2.pk3 package on top of GZDoom to start playing WolfenDoom: Blade of Agony.

Some maps run very slow on my machine. What can I do?

Several maps in Blade of Agony push the engine (and thus, older machines) to the limit. If you encounter slowdowns while playing, simply check the BoA Options in the main menu and reduce the settings for models, special effects and other demanding factors. Sometimes, it's necessary to restart the map after you make these changes. If your performance still doesn't improve, even after exiting any programs running in the background, then your machine just isn't up to the task.

Textures and models are turning black at random! How do I fix this?

Try upgrading to the latest version of GZDoom. If that doesn't help, you may need to upgrade your graphics card drivers or buy a new graphics card.

You may also disable dynamic lighting, but doing this will significantly hamper your gameplay experience. Some areas in the game depend heavily on dynamic lighting, and even require dynamic lighting.

The game is too hard, what can I do?

The first option you have is to play on a weaker difficulty setting (for example "Morgenspaziergang") if the one you have chosen is too hard. Also think of Blade of Agony as a less arcade-style shooter than Doom itself. There is still a lot of action going on but you are not a super-powerful space marine, so enemies are supposed to be more of a danger than Imps or Zombiemen are. If you are still in trouble we'd suggest watching pagb666's brillaint Let's Play videos showcasing all secrets and an excellent walkthrough through all episodes - Chapter 1 | Chapter 2.

Will you add Brutal Doom compatibility?

Yes, when the sun rises in the west and sets in the east, when the seas go dry and mountains blow in the wind like leaves. When Daenerys Targaryen's womb quickens again, and she bears a living child. Then we will return and add Brutal Doom compatiblity, my sun-and-stars, and not before.
