Endless Invader (AppID: 3692930)

Orbit Assault Action Defense Game, Endless Invader!

Endless Invader is the Orbit Assault Action Defense game where you must fend off enemies pouring in from all directions and protect your planet until the very end.
Hold the line with strategy, chaos, and persistence—defeat the final invader and claim your victory!

Become the planet's guardian and stop the invaders from consuming it.

The remote planet Aevinculum breathes with life thanks to the mysterious energy flowing from its core—Terravitalitic Force.
One day, enemies known as the Endless Invader began their assault, seeking to consume this alluring source of power.
Whether by sheer will or destiny, the planet responded by birthing two guardians from its core: Cletinera and Castlan.

In this game, you take on the role of the female guardian, Cletinera, destroying visible enemy units to stop the invasion.
As time passes, enemies will grow stronger and appear in greater numbers. To resist them, you'll need to absorb as many Terravital Spheres as possible from defeated foes to continue growing stronger.

Use the upgrade system to enhance your abilities in various fields.

The more enemies you defeat, the stronger and tougher you become!
Absorb Terravital Spheres dropped by enemies to level up, and open the Upgrader to strengthen your capabilities.
Unleash powerful, flashy attacks, gain unmatched speed, or increase your planet's durability. Carve out your own upgrade path and dominate the game your way.

Make the most of three distinct weapons.

This isn't just repetitive single-attack combat!
You'll be switching between three weapons with completely different attack styles—Blaster, Lance, and Shield.
By investing in weapon upgrades, you’ll unlock unique special attacks and weapon-switch abilities that make your playstyle even more dynamic.

Respond to increasingly powerful enemies with strategic decisions.

Don’t be fooled by the simple appearance of early-stage enemies!
Before you know it, you'll be overwhelmed by enemies that are too strong and too numerous to handle.
Special units that appear mid-stage with flashy entrances will have you sweating.
If it seems impossible to defeat them all, consider your options—hint: pay attention to their colors!

Rely on allies and lucky bonuses for a more stable fight.

You are not alone in this fight!
Trust in Castlan, the male guardian who roams beneath your feet.
He'll attack enemies on your behalf and can even protect you with a temporary shield.
Also, once in a while, luck will be on your side—dropping powerful items that can turn the tide and help you survive even the most dangerous moments.

The key is to keep the planet alive until the end.

The enemy forces aren't truly infinite!
If you resist to the very end, they will eventually exhaust their troops while your planet still stands.
At last, they will summon their final unit.
Defeat this ultimate threat, and victory will be yours.

Only you can change the fate of the remote planet Aevinculum.
Now, head out into the universe of the Guardians!
