About this game

In a near-future warzone,
you will take part in a series of high-risk operations.
Enemies continuously appear, and battlefield pressure steadily rises.
You must stay operational amidst the chaos, complete objectives, and survive.

High-density survival shooting

This is a top-down Roguelike survival shooter.
Combat is fast-paced, and the battlefield is always full of threats.

Shooting is primarily automatic, allowing players to focus on movement and decision-making.
Manual aiming and skill activation are supported, giving you control in critical moments.

The controls are accessible, but the situation constantly forces you to make choices.
You are not facing a single battle, but a sustained, high-pressure operation.

Every upgrade is a choice of direction

Character progression revolves around multiple upgrade paths.
At each upgrade, you must decide between different types of abilities:

  • Steady enhancement of combat capabilities

  • Experimental modifications with trade-offs

  • Deployment and reinforcement of autonomous high-tech devices

These choices interact and accumulate, continually changing how you respond during operations.

Mission system

During combat, you will encounter various emergent objectives.
Completing these missions grants unique upgrades and ability enhancements,
offering more strategic options and making every run different.

Missions do not appear in fixed patterns,
requiring you to adapt to the battlefield—they are both opportunities and tests.

Weapons and battlefield deployables

You can acquire and use a variety of weapons,
each differing in firing style, rhythm, and application scenarios.

Deployable or triggerable items and devices also appear on the battlefield,
directly affecting the situation and altering how you handle enemies and space.

How you use these resources often depends on your current build and judgment.

Special cards and extraordinary effects

The game includes extreme-strength special cards,
providing effects far beyond normal limits.

These cards introduce extraordinary strategic choices
and significantly impact combat outcomes,
making every operation unpredictable.

Characters and skills

Each character has unique passive traits and active skills.
Through building and playing, you can:

  • Enhance skill effects

  • Modify skill usage

  • Unlock unexpected skill variations

Some variations only occur under specific conditions
and cannot be planned in advance.

A world shaped by factions

The world continues to operate.
Different organizations, corporations, and groups act independently,
and their goals are not fully transparent.

You are gradually exposed to the bigger picture
through your actions on the field.
