Underrail - New Armor Mechanics
Styg explains the new armor mechanics of Underrail: Infusion:
Dev Log #7: New Armor Mechanics
It's that time of the year again. All the stars and planets are in the right position and it's time for an Infusion dev log.
We already showed you the extent to which we upgraded the visual aspects of the engine, but the mechanical changes that I've done so far and am yet to do are just as extensive, and perhaps more radical. I'm going to talk about them one by one, in separate dev logs, as I continue to test, tweak, and refine them.
Our immediate goal with the engine and the game is to (re-)implement a number of items and mechanics, get a few areas together, and get the game in a state where it can be played for real, so to speak. Mainly so I can better asses how all these changes work in practice, but also so we can produce a short demo video and show you the game in action for the first time.

So, anyway, let's get to the changes to the armor mechanics and damage resistance in general.
In Underrail, the damage resistance was divided into percentual resistance and flat threshold. Incoming damage would be reduced either percentually or by flat amount, whichever would reduce more damage in any given case. This caused a lot of balancing problems. Threshold was generally either useless or overpowered (especially when stacked in early game), while resistance was hard to progress with armor quality, as its percentual nature made it already scale innately.
All these problems really came to forefront when I was implementing different types of shotgun shells in Expedition. Balancing usefulness of different shells in this system was just impossible and it took a lot of tweaking to make it even remotely decent with liberal use of seemingly arbitrary threshold and resistance ignore factors. At one point I was tempted to just implement a completely different interaction for the shells specifically, but decided against it for the sake of consistency.
Another problem with the old model was that all resistances stacked globally. Meaning: resistances from boots and helmets were equally effective as body armor and they all aggregated when it came to interacting with incoming damage. This made me really hesitant to put a lot of resistances on helmets and boots because, on one hand, I didn't want them to make the high resistance armors completely broken by just maxing (or near maxing) out all the resistances and, on the other hand, I didn't want these items, because of their high resistances, becoming mandatory for characters that use ligher armor in the body slot.
There are other problems too, but these are the main issues, I think.
So how does the Infusion's new system differ from the old one?
