About this game

Description

Supplied by the Steam store

“What lies beyond the endless deaths—and whose hope is it for?” Five days, repeated without end. A world where death is overwritten. The truth that awaits beyond the loop of despair—is it salvation, or...

He wakes to a familiar white ceiling. He hears a girl’s voice say “Nice to meet you”—words he has heard countless times. This is Academy City “Ark.” A world home to three girls with the power to fight the “Phantoms,” mysterious enemies that appear without warning, and a young man named Rei, known as the “Tuner.” To stand against the threat looming five days away, he deepens his bonds with the girls.

PROTOCOL: NOAH

The curtain rises on a hopeless story: one young man who holds the survival of humanity in his hands, and the three girls who fight for it.

About This Game

This is a dialogue-driven scenario adventure, running roughly 6 hours on a script of more than 200,000 Japanese characters.

You play as Rei, a "Tuner," supporting three heroines — Serena, Rin, and Nanano — in their fight against the Phantoms, the threat facing all humanity, through the conversations you share with them.

Against a threat that arrives in five days, you build your bonds with them and stand your ground.

And then the fifth day comes...

After a devastating end, the morning of the first day arrives once more.

What is the secret of this looping world? What are the Phantoms?

Can you uncover the truth behind this story?

■ Steady their bodies and minds through conversation and Tuning

As a "Tuner," you adjust the physical and mental condition of the heroines through your daily communication with them and through Tuning.

The choices you make in conversation shift three parameters.

Tuning lets you move any one of a heroine's parameters dramatically.

See for yourself what endings those adjustments lead to.

■ Overwhelming despair, delivered in full animation: the "Death Ends"

This game's endings are "Death Ends," to be taken in as full animation.

Their despair is the essential factor at the heart of this story.

There are 13 endings in total, 9 of them Death Ends.

Only by seeing every one of them can you learn the truth behind this story.

■ 2.5D Scene Art

The still illustrations you expect from a traditional visual novel are here in abundance.

Beyond that, this game presents 2.5D art — "still illustrations that move" — for a far more immersive experience.
