Description

Tactical mining. A buried signal. A truth someone tried to erase.
You were hired to dig — not to ask what's down there.

You were hired to operate a mining drone at the classified Vault 9 site — nothing more. Every shift is a descent: chart a route, meet the quota, and return before your battery or hull gives out.

Then the static starts to form a signal. Beneath the rock lie artificial cavities, impossible artifacts, and recordings left by Lena Ray — a former operator scrubbed from the records of Asterion Resource Group.

HOW DEEP WILL YOU GO FOR THE TRUTH?

✔ Premium experience — no ads, no in-app purchases
✔ A full 30-shift sci-fi story
✔ Plays completely offline

⸻

⛏ TACTICAL DRILLING
Every block is a decision. Navigate seven geological layers while balancing energy, hull integrity, and cargo capacity. Risk one more block for a rare deposit — or turn back before it is too late.

🛠 BUILD A BETTER DRONE
Upgrade your drill, battery, hull, cargo bay, scanner, and laboratory. New systems let you descend farther, survive hazardous zones, and reveal what is hidden behind solid rock.

📡 A 30-SHIFT SCI-FI THRILLER
Intercept corrupted transmissions, recover Lena Ray's lost recordings, and uncover the real purpose of Vault 9. The final shift demands more than a powerful drone — it demands a choice.

📦 ARTIFACTS AND CONTRACTS
Study what you find, surrender it to the corporation, or pursue a more profitable route. Take optional contracts with special conditions: preserve your hull, recover rare ore, or finish without scanner support.

🖥 INDUSTRIAL TERMINAL ATMOSPHERE
A stark retro-futurist interface, scanlines, signal distortion, warning tones, and a dark ambient score turn your phone into a remote operator terminal.

📴 PLAY ANYWHERE
A fully offline single-player game with touch-optimized controls, a reduced-effects mode, and high-contrast symbols for colorblind players.

⸻

Connection stable. Shift commencing.
Drill deeper.
