UPDATE 9-NOV-2025, Version 1.1. Patch Notes:
-added a custom options menu (J.A.M Options) in the Main Menu
--here players can change the reload behaviour of the weapons (automatic reload, separately for each weapon)
--here players can choose a more traditional Rocket Launcher, if they don't want to use the one shown on the video

OVERVIEW:
DOOMJ.A.M is a gameplay mod that modifies all enemies and weapons in classic DOOM. Its main goal is to be a DOOM mod and ONLY a DOOM mod. That means not going too far with modifying weapon and enemy behaviour, so it still feels like classic DOOM when you're playing, but with a faster pace, a lot more gore and slightly different weapon functions here and there, to make it fresh and modern. This also gives great compatibility with as many WADs as possible.

GAMEPLAY:
You can set the weapons to not reload automatically (default) from a custom options menu. The main reason for this is I like to do weapon swapping (e.g fire the SSG and swap to the rocket launcher for a burst of damage) and this is something you cannot do if the SSG reload is forced. Weapons don't automatically reload after swapping, so you can do higher damage in bursts, but still have to reload later. The ammo is also counted down when you reload, not when you fire. So the total ammo you carry is what you see on the HUD + what's in the weapon. This also means if you reload too early (weapons with magazines), you lose the ammo that was still in the magazine.

THE BLOODLUST MECHANIC: (check the end of the video for a demonstration of this)
Fists and Chainsaw are both replaced with a single melee gauntlet (UAC Demon Smasher). When you kill with it, you gather Bloodlust Fragments (can be seen next to mugshot). On the seventh kill, Bloodlust activates. During this time all weapons have their Bloodlust mode active and become a LOT more powerful. It cannot be manually activated, so you have to make the 7th kill tactically before or during a big fight. The mod has NOT been balanced around this mechanic, so don't feel pressured to use it if you don't want to. It is fun, but very easy to get yourself killed if you go crazy during the effect. It trivialises a lot fights when used optimally.

GORE:
It is a fairly gory mod, without going overboard (I think). There are some things I would like to add in the future, but honestly, at the moment just don't know how to do. Also, I'm constantly reminding myself of the goal mentioned above, to not go too far with stuff like this and have the mod not feel like DOOM anymore.

HUD:
At the moment the HUD uses force scaling, because I'm not too familiar with how to make HUDs yet. It works well with 16:9 and 21:9 so I might just leave it like this. Recommend setting GZDoom HUD scaling to "Adapt to screen size", so the texts in automap and random messages on-screen won't be super small.

KNOWN ISSUES:
There are some small aesthetic problems that don't affect gameplay at all, that need to be fixed at some point (they are very rare). At the same time, there probably are some things I haven't run into yet. Feedback on anything strange you encounter would be very much appreciated.

A WAD TO GO WITH THIS RELEASE:
I've made a DOOM II: Remake to go with the release of this mod.

Constructive criticism on the mod in general will be very welcome.

Very good mod. For those who haven't tried it, please give it a go, its like Quake and Doom 64 was fused together, metal as fuck.




Lots of detailed effects, its up there with Weapons of Saturn in terms of punchiness and polish!
(Note, the double mugshot is just me using an addon, since I was playing with Alt Hud on, I turned on the default hud for sake of the screenshots.)

This was a fun little mod! the rocket launcher sprite's placement took some getting used to, though

Mod updated to v1.1.

UPDATE 9-NOV-2025, Version 1.1. Patch Notes:
-added a custom options menu (J.A.M Options) in the Main Menu

--here players can choose a more traditional Rocket Launcher, if they don't want to use the one shown on the video

If you don't like doing quick weapon-swapping you can set the SSG to reload automatically, like most people are likely used to.
