Update 2.0 — Gems, CORE RUSH, Living Bosses, D80

major update

Deep Core Protocol · published 12 Oct 2026, 08:31 UTC · build 25877140

Our biggest update since launch. Your existing save carries over as it is.

An endless mode you pick from the main menu. Every run starts with a single pickaxe and keeps going down.
Breaking ore fills a gauge; each time it fills you pick 1 of 3 cards to build that run. Mining Drones and all five skills are unlocked through cards too.
Armored, crystal, volatile and pressure ores appear, along with elite ores.
A boss waits every 10 depths (60-second limit). From D70, Overdrive kicks in (score ×1.35) and a risk choice appears every 15 depths.
Scores go to an online Steam leaderboard. The result screen shows your rank and the global board.
Completely separate from the regular mode's progress and save. Regular-mode gems and upgrades don't apply in CORE RUSH, so everyone competes on the same terms.

Relics have become Gems. The Pickaxe, Mining Drone and four skill slots have 24 sockets in total, opening one by one as you go deeper.
Gems come in three shapes: ◆ Method (changes how an attack works), ● Modulation (changes when it triggers) and ⬡ Amplify (raises the numbers). Each fits only its own socket shape. There are 65 gems so far.
Grades go Chip → Fragment → Core → Singularity. Fuse 5 of a grade into 1 of the next, and you can choose which gem you get.
Gems drop from ore. The center core that appears every 5 depths from D5 to D60 now lets you pick 1 of 3 Core-grade gems.
Socketed gems can be removed with Extraction Tools. You start with 3 and earn more each time you reach a new deepest depth.
Auto Place and per-gem locks (excluded from batch fusion) are supported.
Your 12 relics carry over as Singularity gems with exactly the same numbers. Up to 3 Singularities can be equipped at once.
You now run 4 of the 5 skills. If you don't choose, the skills you've invested in most are slotted first.

Every boss now moves around the arena — charging, stomping, gliding, blinking, orbiting, evading, skittering or hovering, each in its own way.
Split — while fragments live, the body takes 70% less damage. Breaking a fragment deals backlash damage to the body; fragments left after 10 seconds merge back and heal it.
Guard — while guards live, the body's shield keeps charging. Break them all and the body takes +50% damage for 3 seconds.
Mirror Images — two identical illusions appear. They can only be hit by direct attacks, and hitting one costs 2 seconds of the time limit.
New boss animations with moving limbs. The final boss changes form at every stage.
Once its seals break, the final boss uses every ability in turn. CORE RUSH bosses move and use abilities too.

To match the firepower Gems add, the mine goes 10 depths deeper.
New boss D70 Abyss Weaver — a spider that moves in short dashes. New ability Web: it anchors threads to the arena edges, and your attack speed drops for every anchor still standing. Cut them all and it gets tangled in its own web: it can't move for 3 seconds and takes +50% damage.
The final boss, Abyss Vein Core, has moved down to D80, with a 50-second limit.
A new ore, Abyss Vein Ore, appears from D75.
The first ending, New Game+ and the true ending now count from D80. If you already beat the final boss at D70, you can keep going from D71.

Damage numbers are bigger and clearer: a thick outline, a pop-in, a slower rise, and they stay on screen longer.
Pick a Damage Size in Settings (Normal / Large / Extra Large).
10 Damage Skins — Steel, Pixel, Crystal, Thunder, Magma, Neon, Abyss, Galaxy, Sakura and Gold. Every skin has separate numbers for normal hits and critical hits.
Unlock them with first boss clears (D10–D80), your first Rebirth, and beating every boss on Abyss difficulty. Choose one in Settings → Damage Skin. They don't affect combat.

All of CORE RUSH and the new Gem, boss and Damage Skin text is translated into English, Japanese, Simplified Chinese, Russian, Spanish and Brazilian Portuguese.
Top-bar buttons and gem socket names now fit in every language.
