Read the configuration without guessing
Sandbox files mix direct quantities, true or false switches, multipliers, and numeric menu codes. The comparison preserves those types and shows the internal key beside a readable label.
Compare stored values
Every row comes from the supplied preset files. The tool compares the saved number, boolean, or string without inventing a difficulty score.
Treat enums as raw codes
Many numeric fields are menu option codes. A larger number does not automatically mean harder, rarer, faster, or more dangerous.
Notice undefined fields
Not defined means that preset file does not contain the field. It does not mean zero, disabled, or identical to the other preset.
Validate after updates
Preset fields and runtime fallbacks can change between builds. Regenerate this archive whenever the monitored game snapshot changes.
Legacy preset caution
Six Months Later contains 119 flattened fields and uses several legacy names, while each of the other supplied presets defines 269 fields. A missing field may be supplied by a game default or runtime fallback, so it should not be interpreted as a gameplay value on its own.
Practical workflow
Build a world you can explain
Start from a supplied preset, compare it against the closest alternative, then record only the settings you intentionally change. This makes future tuning and server troubleshooting much easier.
- 01
Choose a baseline
Pick the supplied preset closest to the experience you want.
- 02
Inspect differences
Filter by system and review exact keys before changing values.
- 03
Document overrides
Keep a short list of intentional changes for future build updates.
Common questions
Sandbox settings FAQ
Which Project Zomboid sandbox presets are included?
The Build 42.20.4 snapshot includes Apocalypse, Extinction, Outbreak, Rising, and Six Months Later. These are the five preset files supplied by the mined game data.
Are larger sandbox values always harder?
No. Some fields are direct quantities or multipliers, but many numeric values are menu option codes. The comparator preserves the raw configuration value instead of treating every number as a difficulty score.
What does Not defined mean in the comparison?
It means the selected preset file does not contain that setting. It does not mean zero or disabled. The game may apply a default or runtime fallback for an undefined field.
Why does Six Months Later have so many missing settings?
The supplied Six Months Later file uses a smaller legacy configuration shape with 119 flattened fields. Each of the other supplied presets defines 269 fields and includes many newer Build 42 options.
Does a zero zombie respawn value always disable respawning?
Check the complete group of zombie population settings, especially RespawnHours and RespawnMultiplier. A single raw value should not be interpreted without the related fields and the current game runtime rules.
Can I copy these values directly into a server configuration?
Use this page as a reference for the supplied preset values, then apply changes through the current game or server configuration format. Validate the result in the same game build because field names, defaults, and runtime behavior can change.
