Keep an eye on modder handles like ZombieBob, IronCarp, and Vexar – they are currently working on: Survivalist Invisible Strain Mods
Before diving into the list, let’s address the "why." The vanilla game is notoriously unforgiving.

3. Advanced Ballistics & Armory (ABA) Author: GunnyRetired The base gunplay is solid, but the weapon variety is sparse. ABA adds over 150 real-world firearms, from the unreliable homemade "Pipe Rifle" to the rare M4A1 and even a .50 cal anti-materiel rifle (requires a bipod to fire). It also introduces ammunition types (FMJ, HP, AP). Crucially, it adds armor degradation; your crafted leather vest will stop a 9mm round once or twice, but a .308 will punch through. This mod makes every gunfight a tactical risk-reward calculation.

It adds soil pH, seasonal growth cycles, and crop rotation bonuses. More importantly, it expands the medical system with herbal poultices that treat infection, painkiller tea from Willow bark, and stimulants from Coca leaves (with addiction mechanics). It makes the "Farmer" and "Doctor" NPC traits vastly more important.
