Just hear me out. Released in 1986, and sold exclusively to departments and military. Mainly meant for Austrian anti terrorist groups.
I know many people enjoy having rare gems, or a few meme guns in games and this community doesn't seem to be the exception. So, why not?
One argument would be its real world practical use. And i agree, a full auto handgun isn't the best IRL. But this is a videogame, you can make a welding rod practical for horde clearing if you so wanted to. And a semi/full auto handgun is just fun to use and that's what games are meant to be in the end. If you disagree with adding the G18, I'm curious to know why and if you could comment your opinions on it.
Edit: I haven't done more research than what's stated on the top. Whether it was ever imported into the US, let alone seen in Kentucky i have zero knowledge of.
Can you try another reinstall but following these steps exactly?
First, uninstall the game, then go to "Steam\steamapps\common\ProjectZomboid" and make sure there are no leftover files or folders there.
After that, go to “%UserProfile%\Zomboid” and delete everything there except the “Saves” folder.
Then just install the game again and see if that helps.
