About ARCS
ARCS is a stage‑based shooter where you build a loadout from over 450 pieces of equipment and confront waves of enemies. Each battlefield’s terrain and object placement can dramatically alter how your chosen gear performs, demanding strategic planning for every encounter.
The game offers multiple difficulty levels that can be switched at any time, letting you pace the story to your skill. Set in a post‑apocalyptic wasteland after the autonomous weapons known as LIV, you play as an enhanced human ARCS sent back into battle after humanity fled underground.
01 / THE GUIDE
Loadout and Equipment
Players assemble their loadout from more than 450 types of equipment before each stage. This selection determines the tactics you can employ against the incoming enemy waves.
Because the equipment pool is vast, experimenting with different combinations is essential to discover optimal strategies for each battlefield layout.
- Try mixing long‑range and close‑quarter gear to adapt to shifting enemy patterns.
- Note which equipment synergizes with the terrain features of a stage.

Stage Terrain and Strategy
Each stage’s terrain layout and object placement can drastically shift the flow of battle. The same stage may require entirely different approaches depending on your gear choices.
Understanding how obstacles and open areas affect enemy movement lets you position your equipment for maximum effect, turning the battlefield to your advantage.
- Observe the placement of cover before committing to a loadout.
- Use terrain that funnels enemies into your strongest attack zones.

Adjustable Difficulty
At the start of each stage you can select from multiple difficulty levels, ranging from beginner‑friendly to intense challenges with aggressive enemy attacks. Difficulty can be changed at any time, allowing you to tailor the experience.
Switching difficulty lets you replay a stage at a new challenge level without restarting the entire game, supporting a flexible pacing of the story.
- Begin on a lower difficulty to learn enemy patterns before increasing the challenge.
- Raise difficulty after mastering a stage to test the limits of your loadout.

- Consider the narrative backdrop when choosing equipment that fits a survivalist theme.
- Reflect on the ARCS’s purpose to enhance immersion during combat.
