Guns you find out in the field have likely been dropped rather forcefully. Guns are fragile. Drop a shotgun on its (wooden) stock and it will likely break/crack.
Or they’re just dirty and prone to malfunctions… unless you happen to pick up an AK.[/quote]
The concept of guns damaged to worthlessness doesn’t make sense in these locations:
Gun shops of various kinds, military bunkers, in people’s homes and FEMA camps.
It does make sense in these scenarios:
On zombies of all kinds, around corpse drops, in survivor camps.
As for “all guns in easy reach would be taken or damaged”, what you’re working against is gun statistics. No state in the continental US has less than 10% gun ownership rate, and only six states are under 20%. Once population loss from the pre-cataclysm exceeded 50%, there were literally more guns than people, and the post-cataclysm reality is that there are thousands of pre-cataclysm guns for every survivor. That’s ignoring the pre-cataclysm lore stating that firearm ownership and production skyrocketed in the years leading up to the cataclysm.
It makes sense to take some steps to restrict gun availability, but factoring in most of what you’re talking about regarding gun destruction only gets us down to the levels of guns that are currently in the game. It would never make sense to bring the number of guns available down to the level where it makes sense for a typical lone survivor to spend the time and energy to cobble together a gun.
If you really like the no guns scenario for some reason, feel free to put together a “scarce guns” mod and I’d be happy to include it, but for the base game it simply doesn’t make sense.
