▶ You are a modern-day white-hat hacker
After countless sleepless nights, you collapse from exhaustion and fall asleep on your keyboard… then wake up in the year 2150!!!
You are trapped inside a collapsing digital world.
The Core System — the heart of this entire networked world — has been shattered into fragments after a mysterious catastrophe. Rogue viruses, corrupted AI, and mutated data entities are taking over every region of the digital OS.
As the last Restorer Hero, you must explore broken OS zones, collect the lost Core Fragments, and restore the system before the entire digital world is erased forever.
Uncover the truth behind this collapsing world, discover why you were brought here — and unlock hidden endings shaped by how you survive.
