It literally doesn't improve the game, at all.
Also, the arms don't even match up to the player character as seen in the cutscenes.
Furthermore, it's literally arm models from Doom 3. Super immersion breaking.
It is a matter of opinion, I feel like it greatly improves the game.
How does it not match the cutscenes exactly? By my count nothing matches the cutscenes anymore as everything should be low poly and low resolution. Any mods you can install, including some of the stuff from the Community Patch would have that issue because it is bound to be different and higher quality than the originals.
Does the arms have "DOOM 3" written on them or something? How the hell is that immersion breaking exactly? You wouldn't know they were from Doom 3 if you weren't told.
Also because single-handed wielding is like, way cooler than two-handed wielding (see collage above).
Try single-handed wielding with a rifle, we will see how cool you look after firing it
I would say it is immersion breaking. How the hell does my character handle a rifle like that?
it's a visual enhancement mod, those are completely out of scope of the Community Patch - anomalies, discrepancies and outright bugs only. exceptions can be granted in some gray areas, like implementing the bullet hole system (was 80% finished, so very strong evidence this was only omitted because of time constraints), or the shotgun hybrid slug which now resides in the AI's inventory instead of its gun (as everyone and their grandma agrees the slug unloading is the single most annoying thing found in the game), but adding a hires version of an object which has been modified to include a new part that wasn't originally there is a 100% no can do (even if the hands actually were true to the original concept, which is indeed not the case).
this is perfectly fine as a standalone mod, available to whoever wants what it offers.
I can't argue with that.
By the way, I could work on the texture a bit to try to get it to look closer to the original arm. It should have clothing on it, and I think I can make it look well enough. Let me see what I can do.
