You should play Dead Island 2 if you haven't already
I did, di2 with half sword are my favourite gore models in gaming.
But i'm more impressed by half sword for a number of reasons:
The damage model is focused on humans and humans are much more delicate than zombie so doing s realistic damage model where hitting a lung instead of another organ can change the blood loss or how much time you have before dying is harder than what they do in di2 where you just whack on resistant zombies and hitting the throat or the jaw or the top of the head change nothing.
Damage change your animations and the enemy animations, so even if di2 has bone breaking tech to some extent and zombies can't use their arms and legs aswell when you break their bones, it's nowhere near as complex as half sword where you have various stage of an arm not working, an hand not working, a knee not working, a foot not working and they are not gonna be able to Flail their weapons as efficently, blood loss make you weaker and you can't swing with much force the more blood you lose, a blunt hit to your head make your whole body woobly and blur your vision (blunt hits to the body gave a similar but minor effect) etc. Etc., by the end of a gruesome duel you can have 2 dudes barely walking and barely keeping their 2 handed weapon with one hand, it's EXTREMELY dynamic amd change the combat in ways that di2 can only dream of.
Althought di2 has better fidelity for gore and it doesn't glitch nearly as much (final game vs something that is free and not even in early access) the gore in half sword is much more dynamic, it barely has any fixed point so you can dinamically cut any part from any angle, you can even cut something small like feets depend on where you strike, it still has some wonky stuff like when you bisect a torse but i swear to god every time i think the system is not actually fully dinamic, i discover another possible cut angle that i never seen before so it is like 95% dynamic, 5% fixed.
This is not really relative to gore, but the game even has a realistic layered armour system where only some weapons can make a dent on a full plate armour and the dents are in real time and it's a fucking pleasure to see.
The sound design of the screams, anguish and gargle of death are on par or better than tlou2, and that game had the most realistic sound design when it comes to realistic violence, i have lower the volume or my neighbours can think that i'm actually torturing people that are asking to be spared
I know the game can look silly in videos because ALL the animations are dynamic and phisycs based but i don't think i ever played a melee game where killing people was more satisfying than this game, and i played for the past 35 years.
You even have nut kicks that can immediately ko someone
