Hollow Dungeon & Crypt Tokens

Hollow Dungeon Part I and Part II

The Hollow Dungeon is a public Roblox event for Build and Kill Zombies, not a permanent map. Roblox's event listing gives the first window as 2026-10-10 14:00 UTC through 2026-10-17 14:00 UTC. The follow-up listing is HOLLOW DUNGEON - PART II, with a window of 2026-10-17T14:00:20Z through 2026-10-24T14:00:20Z. At the 2026-10-22 check those timestamps were unchanged and Part II was still running.

The first listing uses the subtitle HOW FAR CAN YOU GO? and the description "The portal has awakened... What waits on the other side?" The Part II description reads "Power doesn't end in the dungeon...". Those are the official words available. This page does not turn them into a floor list, a boss name, or a reward table that the listing does not contain.

A separate HALLOWEEN EVENT listing starts at 2026-10-24T14:00:36Z, seconds after the Part II window closes. Treat 2026-10-24 14:00 UTC as the deadline for anything you want to finish in the current dungeon.

What Crypt Tokens are

Crypt Tokens are the reward currency attached to the Hollow Dungeon code batch. All six codes distributed for the event pay Crypt Tokens, in amounts of 50, 100, or 250. They are not Cash, not Hacker Tokens, and not Lightning Tokens. Cash buys parts, vehicles, and skill nodes; Hacker Tokens belonged to the September Hacker Event; Lightning Tokens were tied to the expired ZEUS code and are also separate.

Not yet observed: the Crypt Token shop, its prices, what a single item costs, and whether tokens convert to Cash. None of the sources reviewed for this page shows a token balance or a price tag. Those fields stay blank instead of being filled from another site's table.

This page also does not state a token payout per floor or per run. The only Crypt Token amounts recorded here are the code rewards in the next table; all six meet the two-source bar.

The six Crypt Token codes

The 2026-10-18 Eurogamer table and the 2026-10-22 PCGamesN table both list six codes that pay Crypt Tokens. All six also appear in the buildandkillzombies.wiki summary re-read on 2026-10-22, and both independent tables agree on the rewards.

Active means at least two independent write-ups agree on the code and the reward. Pending means exactly one source has it. Pending is not the same as expired: the code may work, but this site will not send players to a code it cannot corroborate.

The rest of the active list

The full active list on /codes/ also includes IAMPRO, COMMUNITY, CashDrop, and MOREFRIENDS. Those four do not pay Crypt Tokens: IAMPRO pays 5,000 Cash, COMMUNITY pays 1,000 Cash plus a Small Engine and a Small Tank, CashDrop pays 500 Cash, and MOREFRIENDS pays two Passenger Seats. They are noted here only so the Hollow Dungeon page does not look like the whole code list.

Rewards are copied from the sources, not retested in-game by this site. If a code returns an error, check /codes/ first; expired entries stay visible there instead of disappearing.

Redeeming in the current Shop layout

The redeem flow depends on the Shop layout in your build. Open the SHOP menu from the left-side button column. In the layout recorded on this page, the COMMUNITY CODES box sits inside the Exclusive Shop tab; community reports from the October Crypt batch place the code field at the bottom of the main Shop menu.

Type the code exactly as it appears in the table, press REDEEM, and confirm the reward lands before entering the next one. In the current layout the code box is part of the main Shop menu; builds that still show an Exclusive Shop tab keep the COMMUNITY CODES box inside that tab.

The complete step-by-step walkthrough lives on /codes/, including what to do when a code fails. This page does not duplicate the whole sequence, so the redeem instructions have one canonical home.

The 1,000 Studs gate on IAMPRO

IAMPRO pays 5,000 Cash, but it has a prerequisite: your best distance must be at least 1,000 Studs. The 2026-10-18 table lists that requirement and the 2026-10-22 recheck still carries it. The code will not pay until the requirement is met.

Check the best-distance stat on the run screen before treating IAMPRO as broken. The gate is separate from the Crypt Token batch: IAMPRO pays Cash, not Crypt Tokens, and it is not part of the Hollow Dungeon reward set.

If the code still fails at or above 1,000 Studs, move on and re-check /codes/ later. This site has not retested the payout in-game, so it does not promise a fix or a workaround.

Badges: no Hollow Dungeon badge as of 2026-10-22

The official badge list on 2026-10-21 still contained three badges: Welcome!, Hacker Event 2026, and You defeated the King 1x1x1x1. A 2026-10-22 recheck returned the same three. There is no Hollow Dungeon badge, no Crypt Token badge, and no Part II completion badge.

The counts on 2026-10-22 were Welcome! 14,606,778 awards with 60,110 in the past day, Hacker Event 2026 7,706,374 with a past-day count of 0, and You defeated the King 1x1x1x1 1,807,261 with a past-day count of 0. A past-day count of 0 means the badge is not being awarded, not that it was deleted.

Because no event badge exists, this page does not promise one for finishing Part II. If the developer adds one, it should appear on the badge API before it appears in a video title, and this page will be updated from that list.

What is still not observed

The following are not in any source reviewed for this page. They are marked Not yet observed rather than filled with numbers from another wiki.

• Crypt Token shop prices and the item list: Not yet observed.
• Token payout per floor or per run: Not yet observed.
• Part II floor count and layout: Not yet observed.
• Dungeon boss name and stats: Not yet observed.
• A Hollow Dungeon or Crypt Token badge: not present on the 2026-10-21 or 2026-10-22 badge list.

What to do before 24 October

Redeem the six active Crypt Token codes first, then IAMPRO if the 1,000 Studs gate is met. Those six code rewards are the only Crypt Token amounts this site can verify, so they are the safest use of the remaining window.

Spend tokens only after the shop shows a price in your own session. Because prices are Not yet observed here, this page cannot tell you which item is the best value. It can tell you the event window and the code rewards, and those are the two facts that expire on 2026-10-24 at 14:00 UTC.

After the window closes, the HALLOWEEN EVENT listing starts at 14:00:36 UTC. Check /codes/ and /updates/ for the next batch; this page will keep the Part II table as a record instead of deleting it.
