From the moment I started playing 7 days to die I noticed that it's not really a survival horror game, but rather a survival action game. You've got running zombies that rip buildings apart rapidly, guns and ammo everywhere and it doesn't take long before you're armed to the teeth and mowing down hordes. I wanted a more survival horror experience like Night of the Living Dead, the original Dawn of the Dead, or the Resident Evil games. Zombies are a slow, shambling horde that will keep coming for you forever. They're not fast but they are relentless. The 7D2D Survival Horror mod makes the simple act of survival more difficult - more books for recipes are needed, guns and ammo are rarer, tools and weapons take more components to build and repair. There is a collection of many smaller changes, fixing or tweaking minor features.
Now to repair your guns, you need to use up gun parts. No matter how well you oil and clean your guns, springs and pins wear out!
