GAME OVERVIEW

A long time ago, a mysterious meteorite crashed onto Earth. It stayed buried deep underground, silent and still, waiting for its time to awaken.

10,000 years passed, and by the time humans built up their civilizations, the meteorite finally stirred. From it, alien “breeds” burst out, spreading like wildfire and consuming everything in their path. The truth? That meteorite wasn’t just a rock—it was actually an alien egg.

The world above was completely destroyed. Governments collapsed, nations vanished, and humanity lost the fight. The few survivors had no choice but to retreat underground, hiding in massive shelters. These shelters became known as the “Arks,” the very last safe zones for mankind. Knock On The Window

But humanity refused to give up. Using their remaining knowledge and resources, they created two special weapons to fight back. One was a manned machine called Father.

The other was a combat clone soldier, designed as a girl, who served as Father’s pilot. Together, stationed in an abandoned front-line base, they prepared for the battle to reclaim the surface.

9th Sentinel Sisters takes this story and throws you into a fast-paced action game with roguelite elements and the thrill comes from mowing down endless waves of aliens in a bleak, near-future wasteland.

You get to build your own loadout with 16 weapon types and 37 upgrade parts, letting you crush enemies with crazy firepower like lasers, drills, and missiles.

Every run is about making choices—do you fight stronger enemies, power up your weapons, or recover and regroup? It’s up to you to adapt, strategize, and push toward survival.
