API snapshot refresh
Games API snapshot taken at 2026-10-24 13:47:45Z: name still Build and Kill Zombies, visits 61,074,636, favorites 1,294,426, and a point sample of 5,860 playing. Max players is still 5. The public description is unchanged — the developer still describes building the car, adding weapons, crushing zombie waves, and earning cash, with no redeem codes — and no changelog or patch notes exist for this game, so nothing else is inferred from the snapshot. Canonical values updated in content/roblox-data.ts; codes, wiki, and guides were not re-checked this cycle.
Crypt code batch, Hollow Dungeon page, API snapshot
Codes re-checked against the 2026-10-18 Eurogamer table, the 2026-10-22 PCGamesN table, and the buildandkillzombies.wiki summary. Ten active: HOLLOW, HOLLOWKING, CRYPTCRAWLER, DOCTORSORDERS, TRUSTTHEJUICE, FORGE, IAMPRO, COMMUNITY, CashDrop, MOREFRIENDS. ZEUS moved to expired after Eurogamer's 2026-10-18 update; PCGamesN still lists it, so the conflict is recorded and it stays inactive. New wiki page /hollow-dungeon/ covers Part II (window ends 2026-10-24 14:00 UTC), Crypt Tokens, the Shop redeem layout, and the 1,000 Studs gate on IAMPRO. Badge API on 2026-10-22 still three badges: Welcome! 14,606,778 (past day 60,110), Hacker Event 2026 7,706,374 (past day 0), You defeated the King 1x1x1x1 1,807,261 (past day 0); no Hollow or Crypt badge. Games API: visits 59,699,910, favorites 1,278,288, playing point sample 6,068, updated 2026-10-19T17:43:22Z.
API snapshot and Hollow Dungeon window
Games API name is still Build and Kill Zombies. The universe updated stamp moved to 2026-10-10T17:46:42.157Z. Visits 52,209,019, favorites 1,172,140, and a point sample of 24,272 playing. The public description is still the generic build, weapons, and zombie-wave text, with no redeem codes. The active code list was not retested in-game and stays the 2026-09-29 multi-source list. Badge API the same day: three badges, no Zeus badge, and no Hollow Dungeon badge. Welcome! 13,335,088 awards, past day 215,796, still awarding, published win rate 0.547. Hacker Event 2026 is still 7,706,374 with past day 0. You defeated the King 1x1x1x1 is 1,807,261 with past day 0, so it is no longer being awarded. That past-day zero does not say the boss was deleted. Roblox lists HOLLOW DUNGEON EVENT from 2026-10-10 14:00 UTC through 2026-10-17 14:00 UTC, subtitle HOW FAR CAN YOU GO?, description "The portal has awakened... What waits on the other side?" A second listing, titled ???, subtitle HOLLOW DUNGEON - PART II, runs 2026-10-17 14:00 UTC through 2026-10-24 14:00 UTC, description "Power doesn't end in the dungeon..." This pass does not add dungeon floors, fragments, rewards, or codes from video titles.
Tier preview
Build and Kill Zombies tier list preview
Start with the strongest current picks, then use the full tier list when you need ranking notes and update dates.
SSkill tree
Luck skills (Luck II → Luck III)
Cheapest compounding purchase in the game: +20% for 250 and +25% for 625. Every roll afterwards improves, which feeds parts, runs, and cash in one line.
SRoll stations
CAR PARTS rolls (engine first)
Your build literally cannot move without an engine, and the ladder starts at 1 in 3. Rolling engines early is the fastest route from naked plot to first drive.
ARun length
Fuel capacity
Fuel is the run timer — a dry tank ends a push wherever it is. Small Tanks from codes and fuel barrels from the shop convert directly into more distance per run.

Wiki coverage
Wiki pages for how this game actually works
Every page here is built from one of two things: the official Roblox data, or moments read frame-by-frame from public gameplay footage. Anything we have not seen yet is labelled instead of guessed.
Roll Machines & Part Ladders
The roll stations, category picker, and the observed engine odds ladder.
Car Parts & Build Slots
Slot types, documented parts, and the missing-parts shop.
Supports & Weapons
Mounted weapons, observed supports, and support slot capacity.
Skills & Permanent Upgrades
The skill tree, luck line, and observed upgrade costs.
Vehicles & Car Builds
Blueprint vehicles, Required Parts, and finishing a build.
Bosses & Events
Boss fights and the in-progress Hollow Dungeon Part II window. The King badge is no longer awarding. Crypt Token details live on /hollow-dungeon/.
Hollow Dungeon & Crypt Tokens
Part II runs until 2026-10-24 14:00 UTC. This page covers the Crypt Token codes and the current redeem layout; unobserved shop details stay labelled.
Zeus and Lightning Tokens
A Zeus boss is not confirmed here. There is no official Zeus badge. Lightning Tokens are a separate currency from Hacker Tokens.
Runs, Distance & Fuel
The run loop: drive, survive waves, push distance, bank cash.
Cash, Tokens & Boosters
Cash sources, expired Hacker Token codes, boosters, and the official passes.
Source check
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.
Official
Official Roblox game page
Source of record for title, creator, description, live player counts, and the four game passes.
Official
Roblox games API (universe 10741654282)
The API snapshot behind the facts bar: visits, favorites, max players, and update timestamps.
Community
Community wikis and code trackers
Used as a cross-check signal only — a claim from a single community source is never published as verified here.
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.
Community research
Video sources reviewed
Gameplay footage reviewed for this site's observed values. These are community videos, credited as research sources — treat them as the evidence trail, not as official patch notes.

FAQ
Quick answers
The questions players actually ask before their first drive.
Is this the official Build and Kill Zombies website?
No. This is an unofficial fan resource. For official support, purchases, and account issues, use the Roblox experience page and the developer's channels.
Are the codes on this site working?
Every active code is cross-checked against multiple independent sources before it is listed, and the page carries the date of the last check. Codes that stop working move to the expired list instead of being deleted.
What is the rarest item we know about?
On the fully documented Engines ladder, the top slot sits at 1 in 12,500 — with 1 in 10,000 right below it. Other categories have their own ladders; those are still being read from footage and are marked accordingly.
Where do the numbers on this site come from?
Two places: the official Roblox API (visits, favorites, description, game passes) and frame-by-frame reads of public gameplay footage, each tagged with the clip and timestamp it came from. Unverified values are shown as not yet observed, never guessed.
Which page should I read first?
Start with Codes for free cash and starter parts, then follow the five-part Walkthrough beginning with Part 1: How the Game Works. After that, the Parts database and the upgrade planner cover the mid-game.
How often is the site updated?
Whenever the game updates, a code batch drops, or a new gameplay session is reviewed. The updates page logs every check with a date so you can see how fresh the data is.
