Build and Kill Zombies Codes

Active codes are listed only after more than one independent write-up agrees on the code and its reward. The 2026-10-22 check compared the 2026-10-18 Eurogamer table with the 2026-10-22 PCGamesN table, then re-read the buildandkillzombies.wiki summary. Six Crypt Token codes — HOLLOW, HOLLOWKING, CRYPTCRAWLER, DOCTORSORDERS, TRUSTTHEJUICE, and FORGE — agree across those independent tables, so they are active. ZEUS moved to the expired list in the 2026-10-18 Eurogamer update; this site did not retest it in-game. IAMPRO pays 5,000 Cash but requires a best distance of 1,000 Studs first. COMMUNITY, CashDrop, and MOREFRIENDS remain active. Ten codes are active in total. Expired codes stay visible instead of being deleted, so you can see what was already tried.

How to redeem codes

  1. Launch Build and Kill Zombies and finish the short starting tutorial.
  2. Open the SHOP menu from the left-side button column. If your build still shows an Exclusive Shop tab, the COMMUNITY CODES box is inside it.
  3. Scroll to the bottom of the shop panel. Community reports from the October Crypt batch place the code field at the end of the main Shop menu; older builds keep it inside the Exclusive Shop tab.
  4. Type a code into the input box exactly as written and press REDEEM.
  5. Check that the reward appears before entering the next code. IAMPRO only pays once your best distance is at least 1,000 Studs.

Code freshness policy

  • A code is only listed as active after it appears in multiple independent sources or is confirmed from in-game footage.
  • The 2026-10-22 pass compared the 2026-10-18 Eurogamer table with the 2026-10-21 buildandkillzombies.wiki check and a same-day re-read. This site did not retest the codes in-game.
  • HOLLOW, HOLLOWKING, CRYPTCRAWLER, DOCTORSORDERS, TRUSTTHEJUICE, FORGE, and the four older active codes met that bar.
  • ZEUS moved to the expired list in the 2026-10-18 Eurogamer update. It is kept visible with its old 50 Lightning Token payout and was not retested in-game.
  • This page is re-checked whenever the game updates or a new code batch drops; the last-checked date is shown at the top.
  • Expired codes move to the expired list instead of being deleted, so you can tell what was already tried.
  • Codes posted only by a single anonymous account are never listed as active.

FAQ

Codes FAQ

Why is a code that other sites list missing here?

Some sites pad their lists with codes copied from each other without testing. Codes only appear as active here after cross-checking, which is why this list starts shorter and stays honest. A code with only one source, or with sources that disagree on the reward, waits.

When do new codes come out?

The first batch dropped on September 12, 2026 during the game's breakout week. A second batch arrived around the Hollow Dungeon event, with six Crypt Token codes in the 2026-10-18 table. Codes are announced through the community channels first, so check back after every update or follower milestone.

What are Crypt Tokens?

Crypt Tokens are the Hollow Dungeon event currency. HOLLOW, HOLLOWKING, CRYPTCRAWLER, DOCTORSORDERS, TRUSTTHEJUICE, and FORGE pay them. They are not Cash, Hacker Tokens, or Lightning Tokens. Shop prices are not yet observed here; the event page at /hollow-dungeon/ covers what is confirmed.

Why is ZEUS no longer active?

Eurogamer moved ZEUS to its expired list in the 2026-10-18 update. The old reward was 50 Lightning Tokens. This site did not retest it in-game, so it is kept in the expired list with that note rather than deleted.

What are Hacker Tokens for?

Hacker Tokens were the Hacker Event currency. The Hacker Event 2026 badge is no longer being awarded (past day 0 on 2026-10-22). The codes HACKER and 1x1x1x1 are expired. ZEUS paid Lightning Tokens, a different currency, and is now expired too. This site did not retest those distinctions in-game.

The code worked but I got nothing — what now?

Make sure you finished the tutorial first; the redeem box only pays out after it. IAMPRO also needs a best distance of 1,000 Studs. If a code still shows an error, it may have just expired — re-check this page, since expired codes are moved instead of removed.
