Make sure you don't have any possibly conflicting mods within the doom_2553 folder, and of course make sure you installed it correctly.

Your mod doesn't work. Cause after I start the game, the cutscene with spaceship approaching the UAC base is not playing and then during the game I can't see anything, only HUD. Like the image is pitch black. I press movement buttons and hear the sound but I don't see anything. And yes, I removed sickmod from the game as you stated in your comments but still, I don't see anything during the gameplay. Everything is pure darkness.

UPDATE: I removed few more sickmod related files and it worked, but then I had to mess with settings a lot to make your mod actually work. Like, I have to change aspect ratio via editing config files to have proper ratio, because I'm playing on big square monitor and seeing image been squashed from the sides is not nice.

But the problems didn't ended there. Cause despite the fact that I am able to play actual Doom 3 on ultra settings, your mod does not wanted to work on ultra settings. Thus I had to lower my graphics to high or even medium, cause it was constantly loading something every time when I move. And just right after when I solved this problem, I have another one.

And that another one is new visuals. You see, original Doom 3 graphics made in the way that, despite how dark the game is, you still are able to see everything around you. But in your mod the image is so sharp that I can't even see enemies that shows up right in front of my face. And I'm not kidding. Your new visuals make game so dark that I hardly can see enemies right in front of me, and since you can't hold a gun and a flashlight at the same time to shine the light on enemies, I had to pull up the flashlight to see who to shoot and then shoot the enemies. And then also when I shoot from some guns or getting shot back at by enemies, I have a huge FPS drop from stable 30 - 60 to 15 - 10. I don't know what you did to your mod but, for me at least it is unplayable.

So in conclusion, here are all pros and cons of your mod.

Pros:

Improved gameplay.
New guns to play with.
Changed characters here and there.
A bit changed HUD.

Cons:

New visuals that makes the game even darker than before.
Shotgun does not allow you to shoot it right after the first shot like in vanilla Doom 3.
No flashlight attached to your suit or gun to allow you to see in new darker visuals.
Performance issues.
If you remove the sickmod then you don't get to use new abilities, like built-in to your suit flashlight and other stuff.
Sickmod that doesn't allow you to even start the game.

Thus what I would recommend you to do to improve your mod and make it better is:

Remove sickmod by default.
Improve performance.
Stick to default Doom 3 graphics, outside of new Halo based graphic elements.
Add attached flashlight option, so that players can use the flashlight however they like.
Add visual settings from Doom 3 Enhanced Edition mod, so that it could be possible to set any screen resolution with any aspect ratio.

Every issue you've described hasn't been reported by anyone else, or are just normal doom 3 config trickery.

I'm really not sure how the mod was completely screwed on your setup, notably the darkness thing, because if anything the game should be brighter.

I don't know what was the problem with the lights. Cause, in vanilla Doom 3 without any mods everything is fine. But when I put your mod in, it suddenly becomes darker. And then, when I shoot any gun, the game lags very hard. Especially when I shoot SMG. You know, that black one.

And then I decided to test the game with some other mods. I downloaded mod called "Weapons of Mars Destruction", installed it and everything worked fine.

So maybe you can release just the gameplay aspect of your mod, without any graphical changes? Just the gameplay part of it, with guns and Halo gear for the marines in the game? Please?? I mean, I would even pay you if I had that much money.

What are you trying to play this on?

Go ahead and try this for me:

Remove all of the pk4s besides Doom 2553.pk4, then go into your main doom 3 folder and copy the "game" pk4s, and then paste them into the doom 2553 folder.

This should completely remove sikkmod.

Ok, so I tried what you recommended to do and it removed sikkmod, but for some reason the lag is still there. I reduced all graphics to minimum and it still lags when I shoot some guns. So yeah, screw it. If I can't play your mod then screw it. I will find something else to have fun with.

I also tested Doom 3 with few other mods, like Classic Doom 3 for example, and it worked great. No lag, no problems at all. So I guess that there is something wrong with my copy of the game if it works with some mods and doesn't work with others.

But thanks for the help anyway.

Well, on my PC lol. Sure, it is not hi-end modern expensive hardware, but it runs games very good. Not all of them, cause for some reason on Windows 10 most of the old games not just lag, they simply don't want to work properly, while before Windows 10 when I was using Windows 7, everything worked great. I guess that Microsoft really screwed up their last two Windows versions.

And yeah, I will do now what you told me and see if it works or not. And I hope that it will do the trick.

I know you're currently working on the Quake 4 mod, but from what I read on Twitter, it sounds like this mod could potentially be remade in the future. Would a remake include the expansions, or are those no longer planned to be covered?

Yeah, hopefully. I complete remake would make doing the expansions much easier
