Build and Kill Zombies Update Log — Patch History & Changes
Build and Kill Zombies update log: confirmed changes from the in-game what's-new panel and API timestamps — Turbo events, Lucky Blocks, Scooter, Cursed Katana and code drops.
This Build and Kill Zombies update log tracks confirmed changes — what the game's own what's-new panel announced, what the Roblox API timestamps prove, and what new content landed in each window. The game is 35 days old as of this writing and updates on a weekly rhythm, so this page is the changelog of record: every entry is dated and source-tagged, nothing is reconstructed from memory.
Latest Update Window (September 2026)
The in-game what's-new panel — read directly in a September 2026 session — advertised this batch:
| Change | Type | Evidence |
|---|---|---|
| Limited Time Turbo | Event | In-game what's-new panel |
| Limited Edition Turbo | Event | In-game what's-new panel |
| Lucky Blocks | Feature | In-game what's-new panel |
| New Vehicle: Scooter | Content | In-game what's-new panel |
| New Weapon: Cursed Katana | Content | In-game what's-new panel |
| New Codes: COMEBACK | Codes | In-game what's-new panel — reward "(to be verified)" |
| 60% Off Gamepass | Sale | In-game what's-new panel |
The API side confirms the cadence: the experience's updated timestamp moves multiple times per week
(most recently September 23, 2026), and the current build sits at 35 days after the August 19, 2026 launch.
What Each Change Means
- Turbo events (Limited Time / Limited Edition) — time-boxed modifiers; the code batch that shipped alongside them (IAMPRO, ROBLOXCLASSIC, SCIFI and friends) expires September 26 per tracker listings, so redeem fast via the codes page.
- Lucky Blocks — a roll-quality feature that pairs naturally with the Gold Roll mechanic documented in the skills guide; exact interaction "(to be verified)".
- Scooter — a new vehicle archetype beyond the car chassis documented on the builds hub; part requirements not yet read on camera.
- Cursed Katana — a new weapon in the Weapons category; odds and value blank until a pickup popup is read (it is on the builds hub's documented-parts table with its source).
- COMEBACK code — announced by name in the panel; the working code string and reward move to the main codes table once confirmed on footage.
How We Track Updates
Two independent signals, both automated: the Roblox games API updated field (sampled alongside our
player count pipeline every 30 minutes) and the in-game what's-new panel read from public
session footage. Community chatter alone never creates an entry here — an update exists on this page when
the API timestamp moves or the panel says so, and mechanics get their own pages only after they are read
on camera.
Update Log FAQ
How often does Build and Kill Zombies update?
On a weekly rhythm since launch — the API updated field moved multiple times per week in September 2026,
and each window has shipped a code batch alongside content.
What was added in the latest update?
The September window added the Scooter vehicle, the Cursed Katana weapon, Lucky Blocks, Turbo events, a 60% gamepass sale and the COMEBACK code — all announced in the in-game what's-new panel.
Where do new codes get announced?
In the game's what's-new panel and the developer's community channels; tracker sites pick them up within hours. Our codes page re-verifies the full list against multiple trackers after every window.
Does an update reset my build or skills?
No reset has been announced or observed — updates have added content on top of existing saves. Builds and skill purchases persist (the SAVES menu stores vehicles across sessions).
