ARCSARCS

ARCS is a stage‑based shooter where you assemble your loadout from over 450 types of equipment, build the optimal strategy for each battlefield, and break through waves of incoming enemies.

Terrain layout and object placement can drastically shift the flow of battle, creating entirely different approaches even within the same stage depending on your chosen combination of gear.

Victory comes from pure strategic thinking. When you finally read the battlefield and execute the perfect plan, the tension and rush of achievement hit hard.

You can choose from multiple difficulty levels at the start of each stage. From beginner‑friendly modes to intense challenges with aggressive enemy attacks, you can freely switch difficulties at any time. Play the story at the pace that suits you best.

◆Waves of Enemies Flood the Battlefield

Enemies appear one after another, and some stages unleash enough forces to completely fill the screen. Your decision‑making and preparation are the key to breaking through.

◆Story

The autonomous weapons that destroyed the world in a single night came to be known as “LIV.”

The survivors fled underground, leaving the surface as a lawless wasteland where supplies and rogue machines roamed freely.

Humanity’s last hope became the ARCS, enhanced humans long condemned for their inhumane origins.

You were supposed to be dead. But the military recovered your body, repaired it, reconditioned it, and sent you back into the battlefield.

Your past actions, your beliefs—everything was overwritten. What remains is a body built only to fight.

“The mission continues. As long as you draw breath.”

◆Character Introduction

Shirogane（CV：Nako Natsuki）

He is calm, rational, and often regarded as the most stable among the ARCS. A professional who suppresses emotion and prioritizes the mission above all else.

Identified as combat‑capable from childhood, he was raised with the expectation of being deployed to the front lines. Knowing the pain of losing comrades, he keeps a deliberate distance from others.

Mikazuki（CV：Nako Natsuki）

She is bright, innocent, and just a little broken—an ARCS who treats speed on the battlefield as proof of her existence, and as everything she is.

She laughs in the face of danger, and she laughs in the face of fear. But that smile isn’t strength. It’s a habit she uses to hide the terror underneath.

Kasumi（CV：tsukiko hata）

She is one of the most analytical members of the ARCS, able to read the battlefield in an instant.

Behind her calm, matter‑of‑fact tone lies the deep scar of losing comrades on the front lines. Because of that, her words always carry a quiet mix of anger and resignation.

Her sense of responsibility is strong, and when it comes to missions, no one is more serious than she is.

Operator（CV：tsukiko hata）

A failed ARCS with limited combat ability.

From the underground command center, she delivers missions to your broken body. Her voice can sound cold—almost detached—but beneath it lies a quiet resolve to keep humanity alive.
