Update 2.0 — Gems · CORE RUSH · Living Bosses · D80
Our biggest update since launch. Your existing save carries over as it is.
New Mode — CORE RUSH: ENDLESS
- 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 → Gems
- 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.
Boss Overhaul — Living Bosses
- 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.
Final Depth D70 → D80
- 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 · Damage Skins
- 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.
Localization
- 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.
Performance
- Fixed a 0.2–0.3 second stall when CORE RUSH refilled the field with ore.
- Damage numbers are lighter to draw, so busy screens drop fewer frames.
