What was the latest Drill to Earth's Core update?

The Halloween event update. The game updated at 05:25 UTC on 17 October 2026, and the official event starts at 14:00 UTC the same day. The developers say it adds a new currency and a limited-time class you can earn. The class is most likely Jack-o'-Lantern, whose badge appeared on 16 October. Next up is Soul Prison, a Tier 5 dungeon, scheduled for 24 October.

When does Drill to Earth's Core update?

There is no fixed schedule, but the cadence is roughly every one to two weeks — September alone brought Prospector (3rd), Samurai (18th) and Mercenary (26th). This log is re-checked daily against the game's badge API, so it updates the day something ships.

How are the release dates in this log verified?

Every class, NPC and system unlock has its own badge in the game's data, and the badge creation date is the day that content was added. That is why this log carries exact dates where hand-updated wikis often say "as of launch".

What is the next Drill to Earth's Core update?

Soul Prison, scheduled for 24 October 2026 on the game's Roblox events feed. The developers call it their first Tier 5 dungeon, with procedurally generated dungeons. Beyond that, the pattern since March is a new class every one to two weeks, and the badge API shows staged content before it goes live — this log catches both: a new badge is the "coming soon" signal, and its first unlocks are the release.

Drill to Earth's Core Update Log — Every 2026 Update and Release Date

What this log is

Drill to Earth’s Core ships content fast — a new class has landed roughly every one to two weeks since launch — and the in-game update notes are not published anywhere official. So this log is built from the one source that never lags: the game’s own badge list.

Every class, NPC, layer and system unlock has a badge, and the developers create the badge when the content is added. That makes the badge’s creation date the release date — the same method behind every class date on this site, and the reason this log has exact dates where the Fandom wiki’s update page still says “we are missing much info”. Treat a date as the ship day, give or take a day for timezones.

October 2026 (current season)

Three new classes so far, plus the first enemy badges since March, one new addition to the bestiary and the Halloween event.

Date	What shipped	Notes
1 Oct	Engineer class badge created	“Unlock the Engineer class”, the 28th class. It’s awarding unlocks, but slowly (524 by 17 October); price and kit not published yet. Engineer page
3 Oct	First redeem code — GAMENAME (500 Cores)	Source-dated rather than badge-dated (first listed by BloxRant on 3 October; video-verified 4 October). The game shipped no code system at all through September. Details on the codes page
6 Oct	Blinker enemy + three “Defeat a …” badges	Blinker, Fuel Leech and Watcher each got a defeat badge in one batch. Blinker is new (its wiki page dates to 5 October); Fuel Leech and Watcher had been in the game since August without a badge. Bestiary
7 Oct	Vampire class badge created	“Unlock the Vampire class”, the 29th class. Over 30,000 unlocks by 17 October. Creators call it a 3-diamond class; kit not published yet. Vampire page
10 Oct	Game build refreshed	The game’s events feed listed this slot as “Passive Rework!” (subtitle “Passive Overhaul!”). No patch notes, and no new badges dated to it.
16 Oct	Jack-o’-Lantern class badge created	“Unlock the Jack-o’-Lantern class”, the 30th class. Still zero unlocks at 05:36 UTC on 17 October. Jack-o’-Lantern page
17 Oct	Halloween Event update	Game updated 05:25 UTC and its name now ends in 🎃👻. The official event starts 14:00 UTC and promises “a new currency and a limited-time class you can earn”. The class isn’t named, but Jack-o’-Lantern is the only staged one. No new badges came with this build.
23 Oct	Timekeeper class badge created	“Unlock the Timekeeper class”, the 31st class. Zero unlocks on 24 October, so it’s staged. Price and kit not published yet. Timekeeper page
31 Oct	Spider Queen class badge created	“Unlock the Spider Queen class”, the 32nd class. Zero unlocks on 31 October, so it’s staged. Price and kit not published yet. Spider Queen page

Classes kept coming in October: Engineer, Vampire and now Jack-o’-Lantern, roughly one a week. Jack-o’-Lantern is the only one not playable yet, and the Halloween event is the likely way you’ll get it.

September 2026

The busiest month so far — three class drops plus the update that finally unlocked the Mercenary.

Date	What shipped	Notes
26 Sep	Mercenary class + Lieutenant NPC go live	Game updated 05:48 UTC; both badges began awarding within the hour. Mercenary page
25 Sep	Lieutenant NPC badge created	“Talk to the Lieutenant” — staged, no unlocks yet
23 Sep	Mercenary class badge created	The 27th class — staged in the game’s data for two and a half days
18 Sep	Samurai class	Tier 5, 30,000 Cores. Creator coverage of the same update documents Unranked mode and Death Crates. Samurai page
3 Sep	Season 1: Prospector class + Simon the Shopkeeper	Two badges created minutes apart — the class + NPC pairing that marks a new season. Prospector page

The September story in one line: content now gets staged before it ships. The Mercenary badge sat at zero unlocks for two and a half days, and the Lieutenant badge appeared the day before the update — both went live together on the 26th. The class + NPC pairing is familiar (Prospector and Shopkeeper were created 61 seconds apart on 3 September), but the gap between “in the game’s data” and “reachable in game” is new.

August 2026

Date	What shipped	Notes
28 Aug	Salvager class + the Heart Layer	Three badges the same day: Salvager, “Mine Heartgem” and “Heart of Earth” — a class plus a new deepest layer. Salvager page
19 Aug	Witch class	Tier 2, 3,000 Cores — the cheapest of the late-summer classes. Witch page
14 Aug	Executioner class	Tier 5. The wiki’s update log for this window also describes Bombo (an enemy that disables drill parts) and story quests — but it dates the Shopkeeper to this update too, while the Shopkeeper’s own badge is 3 September. We trust the badge. Executioner page
6 Aug	Priest class	Tier 5 support healer. Priest page

July 2026

Date	What shipped	Notes
31 Jul	Gunsmith class	Tier 5, weapon crafting focus. Gunsmith page
28 Jul	King’s Armor	A new armor tier above Phoenix — only 49 players had the full set when we checked.
24 Jul	Crafter class	Arrived two days after the crafting system itself. Crafter page
22 Jul	Crafting system	Five level badges (Crafting I–V) created in one batch — the biggest non-class system drop of the year.
17 Jul	Recruit class	Tier 1 at 100 Cores — the cheap starter combat role. Recruit page
10 Jul	Nightcrawler class	Stealth and dark-layer survival. Nightcrawler page
8 Jul	Crazy Zack NPC	“Local Lunatic” badge — a new town character.
3 Jul	Princess class	Diamond value and staff heals. Princess page

June 2026

Date	What shipped	Notes
26 Jun	Pirate class	Gold bars and cannon damage. Pirate page
19 Jun	Lucky Looter class + Phoenix Armor	The economy class plus the armor tier that still gates late-game survivability. Lucky Looter page
11 Jun	Bounty Hunter class	The bounty coin multiplier class — its NPC counterpart shipped back in March. Bounty Hunter page
5 Jun	Racer class	The speed specialist. Racer page

May 2026

Date	What shipped	Notes
29 May	Goblin King class + Gibbles NPC	A Tier 5 class and a town character in the same drop. Goblin King page
19 May	Emerald ore	Added to the mining ladder two months after launch.
12 May	Reaper class	Soul orbs and late-run sustain. Reaper page

April 2026

Date	What shipped	Notes
30 Apr	Demolitionist class	Explosive damage. Demolitionist page
27 Apr	Postmaster NPC	Town character — the mail system’s anchor.
22 Apr	Excalibur	A rare weapon tied to its own unlock badge.

March 2026 (launch month)

The game page itself dates to 25 February 2026, but the first player-facing badges land in March — the “Welcome” (join the game) badge on 13 March is the best launch marker. Launch month built the whole skeleton of the game in three weeks:

Eight launch classes — Miner, Scout, Tank, Gunslinger, Mechanic, Healer, Driller and Bruiser, with badges dated 13–14 March. Every one of them still costs 100–5,000 Cores.
The layer ladder — Grass and Dirt (23 March), then Stone, Clay, Fossil, Crystal and Toxic (20 March), then Radioactive, The Abyss and The Void (19 March), ending at Reach the Core.
The economy and gear loops — drill upgrades I–V (5 March), the armor tiers from Rusty to Void (9 March), ores from coal to ruby (9–10 March), wall damage (27 February–2 March).
The town NPCs — Blacksmith, Mage and Banker (11 March), Merchant (26 February), then Postmaster (27 April) and the rest of the roster through the year.

What’s next

One update is on the calendar. The game’s Roblox events feed lists Soul Prison 👻⛓️ for 24 October 2026 (14:00 UTC). The developers describe it as “our first Tier 5 dungeon, procedurally generated dungeons, and more”. That’s all they’ve said, so there are no loot or enemy details yet. The current dungeons are covered in structures and dungeons.

The developers don’t publish patch notes. Beyond the events feed, two things are worth watching, both from the badge API:

A new badge appearing = content staged. That is how the Mercenary and Lieutenant both showed up before they were reachable.
That badge’s first unlocks = the content went live. This log and the all classes page both update from the same daily check.

If you are planning a build around the next class, the class cadence is the thing to read first — a class you save for can be superseded in a fortnight.
