If you want your mod to appear on hardcoredoom.com, you will need to follow the steps and meet the requirements below:

Prohibited Content

We do not allow any mods that contain any of the following:

  • Illegal Content: Nothing in your mod or mod files may contain anything that would be considered illegal material or content by the standards of the law.
  • No NSFW Material: Pornographic content, nudity, and similar visuals are strictly prohibited. This includes anime and hentai, so don't try to cheat the system with perverted "fan service." We will reject your mod even if there's no overt nudity.
  • Political & Social Commentary: This isn't a place to rant about Donald Trump or wokeness. If your mod contains anything related to politics, social issues, religion, or similar topics, it will be rejected.
  • Harmful Code or Misleading Links: Mods may not include any code or game code that can cause harm, such as altering a user's settings, crashing or restarting their computer, or other similar actions. Mods also cannot contain advertisements or links to websites that are not directly related to the mod itself, such as unrelated promotions or spam.
  • Stolen Assets: Doom modding has a long history of borrowing assets from other games, and we allow some tolerance for this. However, this is a gray area, and your mod may be removed immediately if there are complaints about uncredited or unauthorized use of assets. Mods that clearly steal assets from newer games or commercial projects will be rejected outright.
  • Monetization: Mods must be completely free to download and use. You may not request payment or any form of compensation in exchange for access to your mod or its content.
  • Mods for unsupported games: For now, we only accept mods for the following games: Classic Doom (any version), Doom 64 (TCs or remaster), Heretic, and Malefact. If your mod does not fall into one of these categories, it will be rejected.
Setting Up the Folder

Your mod folder must share the name of your mod but cannot use spaces or unusual characters. Ideally, it should be named something like this: MyCoolMod.zip

The folder itself must contain the following items:

  1. A gif file that contains all your screenshots (see Screenshot Gif below).
  2. A txt file that contains critical information about your mod (see The Text File below).
  3. Your actual mod files.
Screenshot Gif

If your mod contains levels or maps, you must include a screenshot of the starting area (the first thing the player sees when the map begins) for each one and merge them into an animated gif.

You can do this here: https://ezgif.com/maker

The pause between frames (delay time) should be set to 1 second (100 tics).

Once created, add the file to your mod folder. This gif will be displayed on your mod page.

Creating the Text File

Once you've created the screenshot gif, download the submission form and fill it out. This form contains important information about your mod. Filling it out correctly is critical because the mod browser uses this information to filter mods based on their content.

Once completed, include the text file in your mod folder and give it the same name as the folder itself, for example: MyCoolMod.txt

Moddb Vs Internal Hosting

You're almost ready to submit your mod, but there is one final decision to make: how you want your files to be stored.

There are two options:

  1. Upload your mod to ModDB: Create an account (or use your existing one) on ModDB, upload your files there, and include the link in your mod's text file.
    • Pros: You can continue updating your mod even after it's been submitted. The download button on your mod page will direct users to your ModDB page.
    • Cons: If anything happens to your ModDB page or account, or if ModDB ceases to exist, your mod will no longer be accessible.
  2. Include the mod files directly: Include the mod files inside the folder, and we will store them on the site for users to download.
    • Pros: Greater safety. Hardcore Doom is hosted on Cloudflare's free tier, meaning there are no hosting costs, and your mod has a high chance of long-term survival.
    • Cons: You won't be able to easily update your mod after submission. While you can request a manual replacement, this process is tedious and not recommended. This method is best suited for simple level packs and campaigns.

Important Note: If the unzipped mod folder is larger than 100MB, you must upload it to ModDB. We do not accept files larger than 100MB for internal hosting.

Join the Discord

The first step is joining the official Hardcore Doom Discord. Once there, introduce yourself and request that your role be upgraded to modder status. You can do this in the general channel.

After that, upload your mod in the mod-submission channel and tag me using the @ sign followed by my username, hardcore_gamer. I will then take care of the rest, assuming you followed all the steps correctly.
