About This Game

Tell me, Jupiter, where are we going?

Mercurius Blue: ReCollection

Lost memories. A dead network.

One girl stands between the past and what comes next.

A cult-classic cyberpunk adventure RPG from the 2000s indie scene returns in full HD.

Preserving its original atmosphere and beautiful soundtrack, Mercurius Blue is reborn for the modern era.

■ Story: A Decaying World and 1-bit Diving

The girl was once an orphan.

She still remembers the terror of the midnight flood that swallowed the city.

Yet the faces of the family she once had are gone.

Strangely, she never thought of herself as unfortunate.

At a certain point, children are forced to leave the orphanage and find their own way in the city.

They must work, survive, and learn quickly. The world is in slow decline.

The earth is exhausted. And those without families are sent out far too early.

After leaving the orphanage, the girl spent years living and working in Gaiapolis.

Long enough to learn how the city breathes. Long enough to understand what it takes to endure.

Federal Republic of Gaia.

Nearly a decade after the end of the Great War, a unified government was established.

Hailed as a new awakening for humanity, it was named the Federal Republic of Gaia.

GC 640. Six hundred and forty years have passed since that day.

This is a story of people living in the twilight of an age.

It Started with a Cheap Job

The girl is a rookie Omega Diver.

She dives deep into the discarded network using dangerous methods to retrieve data sleeping there.

Established only in the last decade, this technology was known as 1-bit diving.

"All right, all right. I can introduce you to some leftovers."

A simple data recovery job at the 2nd of Spade.

Just another routine task where nothing is supposed to happen.

But what she finds is an S-Link that should not exist.

And a strange message marked with a date from a hundred years ago.

Dreamer of endless dreams, keeper of the promised key.

Hearer of sealed voices, seer of hidden paths.

The coordinates are set. The call has been delivered.

Those who answer shall arrive.

"Tell me, Jupiter, where are we going?"

The answer may be hidden somewhere within that vast sea of information.
