Is there any mod that fixes enemies mechanically (damage, armor mechanics, weapons) and in terms of AI?
RTX is nice and all, but gameplay is where Q2 needs help the most, especially enemies and related mechanics.
Fix that and Q2 becomes, maybe rather bland and definitely not non instant-classic tier, but a solid (say, 7/10) FPS nevertheless.
But without fixing those it's turbo-casual bad joke of an FPS.
For some reason I hate the guns in Quake 2.
Eh, guns are mostly ok. Pretty bland and pedestrian, like most of the stuff in game, just a reiteration of iso standard classic FPS arsenal (that Id itself pioneered), but workable and even fun to use.
Two exceptions in the positive sense would be CG and HB. Both are rotary guns but each has its own mechanical quirks making it feel unique and not just a rapid fire gun that happens to have a gatling 3D model - you feel that gatlingness.
Many of the guns feel kinda of cumbersome to use but the worst is what they had to do to the AI to compensate for that, by making them pause or trip over themselves randomly and once you figure out their movement you can basically run circles through all of them.
That, and the excessively samey art style are the biggest problem with the game.
The most important flaws summarized.
The guns did feel clunky-ish, but the devs didn't HAVE to fuck up the AI, weaksauce the enemies AND half the enemy damage because of that. They chose to do that make the game casul and retard friendly.
That, combined with the monotony of the locations and gameplay ensures that there isn't much of a reason to play Q2, unless you're part of some MP community for which SP flaws are irrelevant.
