A trainer for single-player Project Zomboid saves that keeps hunger, thirst, fatigue and boredom filled, freezes injury states and lets you edit skill experience for carpentry, mechanics and the rest of the profession list. Weapons and tools no longer degrade on use, and ammo stacks refill on demand.
A quiet-zone option pushes zombie population away from the current cell, which makes base design and interior builds far easier to plan. Every tweak is written to a copy of the save, so the original sandbox stays intact.
