When it comes to the remake, I'm not sure if the design philosophy will change much from the initial version, namely in the area of not including any Halo enemies or Halo themed ones besides the MarSec/Marine ones. However, if that has changed any, I have some ideas I wanted to get off my chest. I do present them knowing that they more than likely won't be used, at least not to their full extent.

[Spoilers ahead for those who have not played. Struggled with spoilers tags, sadly)



1. While I believe Covenant remnants should still remain mostly out of it, I do believe they could be used as the basis for new zombie types, mainly sourced from the crew of The Long Night of Solace. However, there is also the idea of having a limited Swords presence, possibly hired Kig-Yar mercenaries (obviously not in the Delta Complex or other extra secretive areas).

2. Expanding on the previous idea, maybe a one-off encounter with an opportunistic scavenger party the player can fight as a callback of sorts before they get transformed, mainly serving to compare/contrast their regular combat abilities vs. the zombie ones before the latter is thrown into the regular gameplay loop.

3. The Flood. Given the samples stored and all the chaos going on, perhaps an outbreak starts. During the course of this outbreak, a preexisting connection between the parasite and Hell is discovered (namely, Hell's forces playing a roll in the corruption of the Precursor's dust form), and the two are quite possibly allied. That, or the connection could be established without any outbreak.

@ Valkyries7331

the object shimmer is really bad, the floor gratings are all wavy and distorted and there's no option in sikkmod to smooth them out. is there a fix?

it doesn't even start the first cutscene, it says it fails to spawn player_doommarine or something

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.

maybe set up your keybinds in the sikkmod options before you complain, the "headlight" works with any equipped weapon.

while you're at it, upgrade to a machine from this century? might help with the performance lmao

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.
