Build and Kill Zombies Wiki

Official and community sources

Every number on this site is traceable. This page explains what each evidence tier means and links the sources behind the data.

How a number gets published

Official data comes from the Roblox API. Everything else must be read frame-by-frame from public gameplay footage and carries the video ID and timestamp it came from — like '1 in 12,500 on the engine ladder, seen at 2Dqojvu48eo@02:46'.

What we do not do

We never estimate a value we have not seen. Missing numbers are shown as 'not yet observed' rather than as zero or a guess, and no price is listed without a frame or API behind it.

No fake code list

The codes page states exactly which codes are cross-verified and when they were last checked, instead of padding the list with copied rewards that were never tested.

Freshness policy

The game updates weekly. Every page carries the date it was last re-checked, and the updates log records what changed — so you can judge how much to trust a number before relying on it.
