About the field lab
A fan-made data site built to earn trust one reproducible record at a time.
Why this site exists
Build and Kill Zombies has a clean optimization loop, but the official page does not publish the data needed to compare builds. This site turns readable game observations into a dated database and transparent tools.
Evidence labels
| Label | Meaning |
|---|---|
| Official | Visible on the official Roblox experience or a first-party creator source. |
| Observed | Visible in a dated gameplay capture or sampled by a named third-party source. |
| Community lead | Useful for investigation, but not enough to publish as fact. |
| Unknown | No adequate evidence yet. The field stays explicit instead of being guessed. |
Record an observation locally
A useful record includes the exact game identity, readable item or enemy name, the field being proved, server/update date and an uncropped context frame. One screenshot may prove a price but not a hidden damage formula.
Add an observation in the Weapons database, or use the Parts and Zombies databases. Records stay on your device and can be exported as JSON or CSV. There is currently no public submission channel, so a local entry is not sent to us or published.
