About This Game

Hold the line against endless alien swarms with overwhelming firepower.


Take command from a fixed defensive position and unleash a storm of projectiles. Switch between firearms, deploy automated turrets, and call in devastating long-range artillery to crush waves of alien monsters before they break through your defenses.



Projectile-heavy defense shooting

Mow down light enemies with sustained machine-gun fire, blast armored targets with rockets, and stop close-range threats with powerful shotgun bursts. When the swarm becomes too dense, call in artillery support and cover the battlefield in explosions.


Turrets, artillery, and screen-filling firepower

Build up your defensive arsenal with automated turrets and powerful upgrades. Combine your own weapons with support fire to create a wall of bullets, shells, and explosions against the incoming horde.



Fully hand-drawn, frame-by-frame adult animation

Between battles, deepen your bond with three heroines and unlock highly detailed, fluid adult scenes.


Characters


Celine

"Even though I don't know how to fight, I will do my best to be your strength... on and off the battlefield."

A gentle local villager who supports you as a guide and logistics assistant. In the middle of smoke, gunfire, and endless alien attacks, she becomes your rare source of warmth and comfort.


Lina

"What are you looking at? Never seen a genius fix a cannon before? Keep talking nonsense and I'll stuff you in the barrel and fire you out!"

A hot-tempered heavy artillery mechanic with a love for machines, gunpowder, and excessive firepower. Give her scrap metal, and she will turn it into something loud, deadly, and extremely useful against the swarm.


Nora

"Threat elimination confirmed... I'm going to sleep now. Don't wake me unless the base explodes."

A lazy but brilliant scientist whose automated turrets are far more dangerous than her attitude suggests. She may lack common sense, but her inventions can tear alien waves apart.


Dual Growth of Bond and Desire

Survive brutal defense battles, grow closer to the heroines, gain powerful exclusive combat abilities, and unlock fully animated adult scenes as your relationships deepen.
