Silence eventually becomes uncontrollable firepower.

ENDLESS SIGNAL is a minimalist idle hack-and-slash shooter designed to be played in a small window.

At first, you can only fire weak single shots and a few missiles.
Defeat enemies, collect coins, and gradually upgrade your ship.

But once your upgrades and equipment begin to synergize, everything changes.

Fire rate.
Projectile count.
Massive missile barrages.
Support attacks.

The moment those systems start chaining together, the once quiet battlefield becomes completely flooded with bullets and effects.

A tiny window slowly spirals out of control.
That is the core experience of ENDLESS SIGNAL.

Upgrade Your Unit and Survive

Increase your attack power, fire rate, projectile speed, movement speed, coin multiplier, maximum HP, and more.

Use the coins earned from defeated enemies to continuously strengthen your build.

Enemies that once overwhelmed you will eventually vanish in seconds under overwhelming firepower.

Dangerous Power-Up Items

ENDLESS SIGNAL features equipable “Power-Up Items.”

Each item comes with randomized options, meaning even identical equipment can perform differently.

Beyond standard S-rank items, the rare
“U (Unique)”
and
“UU (Ultra Unique)”
ranks can fundamentally alter the game itself.

• Fuse weapons and support systems together

• Transform the behavior of your attacks

• Push your build into absurd territory

The moment you discover a broken combination, your build awakens completely.

Raise Weapons and Create Your Own Build

The game contains 8 different weapon types.

As you continue using them, they level up and evolve into more powerful forms.

• Weapons that spin while spraying bullets

• Extremely high-damage sniper weapons

• Shotguns that wipe out wide areas

• High-risk melee weapons built for close combat

Your combat style changes dramatically depending on the weapons you choose.

SIGNAL REBOOT

After earning enough coins, “SIGNAL REBOOT” becomes available.

This is ENDLESS SIGNAL’s prestige system, but without the frustration of losing all your progress.

Many upgrades and progression elements can be carried over, allowing you to continuously strengthen your ship and push into deeper layers.

The “SIGNAL” Sleeping in the Final Layer

Combine countless upgrades and challenge the boss waiting in the deepest layer.

If you obtain powerful items or broken synergies early enough, you may clear the game far faster than expected.

Rather than endless grinding, ENDLESS SIGNAL is designed around a satisfying pace that leaves you thinking:

“Just one more run.”
