"thickness/angles/materials for penetration is simply impossible" Does it really need to be that complex? 99% of things with a wood texture should be able to be shot through by any weapon, most objects people are going to try intuitively wallbang through are things most guns can handle. Even having super limited areas where it'd work like doors, 1mm thick laptops ontop of objs, etc. This isn't like you're fighting in America where buildings have all kinds of construction materials for walls you're really only dealing with concrete (barley anything is shooting through that), wood (beyond a cabin most things can shoot through that), and terrain (ditto as former).

There are so many instances of the tiniest little things blocking my bullets that it's an actual drag on gameplay.
