Hey, this isn't really the place for this, however:       I suggested almost everything you did plus more. The only thing I didn't really touch on is quality of ammo (because that seems extremely unfun to deal with) and penetration (9mm definitely cannot penetrate multiple walls, it loses about 80% of its velocity after going through one wall of drywall) and there is no scenario I can personally think of where adding projectile penetration to walls could improve the experience rather than hurt it. Imagine attracting a group that otherwise wouldn't have heard you because your .45 acp round just punched straight through two buildings and hit one of the infected in it, or breaking all the windows on your car because of a tricky fight.    Overpenetrating living targets is cool though. I'd like that.

This is cool, and I'm not saying otherwise, but I am saying that this does contradict established lore (such as immunity as a concept), and also:   The zombies are cosmic horrors well beyond the realm of human understanding, while this isn't stated outright, there is a solid chance that the 'knox virus' isn't from our world at all. This is hammered in repeatedly during the CDC plotline. Even the top specialists who had likely been dealing w/ this well before it went viral said that the world was not prepared. It seems like a farse that they would have this intimate of knowledge of the virus, especially given their entirely inadequate response. If they knew all of this, you bet the quarantine procedure would have looked way different.

They did have a dedicated CM, he got tired of dealing with disgruntled customers and jumped ship.   I'm ashamed to admit at one point I was that disgruntled customer, Sorry Enigma.

Actually, those dead bodies are implied to be recent survivors.   Also, this sounds cool for a sandbox setting, but as a default, the zombies are cosmic horrors that are simply beyond human understanding, which is a point the game hammers in w/ the CDC plotline.   I could see this being something sprinters do in extinction though. Randomly latch onto the 'freshest' zombie nearby and take them down, but it seems that the zombies don't need food.

It got a little better in LV after 42.19.  But the Secret Mil Base in RW still has lighting issues with flashlights.  Static interior lighting seems to be okay.
