This mod adds cheat options:
Project Zomboid: Cheat (Cheat Menu) [2.5.1] Free Download
Immortality, no hunger, no thirst, no panic and more
You don’t need to turn on the menu, just press PKM (right mouse button) on an empty place (road for example)
Installation: Extract the folder from the archive and move it to -> C: \ Users \ Username \ Zomboid \ mods
Activate the mod in the game through the “Mods” section
For correct work, build 33 is better and fresh
