Arcs

Arcs is a stage-based shooter in which you assemble equipment and plan how to break through waves of enemies. You choose from over 450 types of equipment, with terrain and object placement affecting the flow of battle and the approaches available for each loadout. You can select a difficulty at the start of each stage, from beginner-friendly modes to challenges with aggressive enemy attacks, and change it at any time.

Story

Autonomous weapons that destroyed the world in a single night became known as LIV. Survivors fled underground, leaving the surface a lawless wasteland where supplies and rogue machines roam. Humanity’s last hope is the ARCS, enhanced humans once condemned for their inhumane origins.

You were meant to be dead, but the military recovered your body, repaired and reconditioned it, then sent you back to battle. Your past actions and beliefs have been overwritten, leaving a body made to fight.

The ARCS

• Shirogane: Calm and rational, he is often considered the steadiest ARCS. Identified as combat-capable in childhood, he was raised for frontline deployment. Having experienced the loss of comrades, he keeps his distance from others and puts the mission first.
• Mikazuki: Bright, innocent and somewhat broken, she treats her speed in battle as proof of her existence. She laughs at danger and fear, but the smile hides the terror beneath it.
• Kasumi: An analytical ARCS who can quickly read the battlefield. The loss of comrades left her with a deep scar, and her matter-of-fact words carry anger and resignation. She has a strong sense of responsibility and takes missions seriously.
• Operator: A failed ARCS with limited combat ability. From an underground command center, she delivers missions to your damaged body. Though her voice can sound detached, she is quietly determined to keep humanity alive.

Battlefields and difficulty

Enemies arrive in successive waves, and some stages send enough forces to fill the screen. Preparing your equipment and making decisions during battle are key to pushing through. The shifting terrain and object placement can make the same stage play differently with different gear combinations.
