Project | Zomboid Debug Mode Gog
Debug Mode is an internal developer tool. Using it can permanently alter your save files, disable achievements (depending on the version), and ruin the intended difficulty. Back up your saves ( %UserProfile%\Zomboid\Saves ) before proceeding. How to Enable Debug Mode (GOG Specific) The process is the same as the Steam version, but you must launch the game directly, not through the GOG Galaxy overlay for best results.
Use Debug Mode sparingly. It's excellent for recovering from glitched walls, testing base layouts, or respawning a lost sledgehammer. But overusing teleport or god mode will empty the game's tension in 20 minutes. For pure cheating, consider the "Cheat Menu" mod (available for GOG if manually installed) instead—it's less intrusive. project zomboid debug mode gog
