Radilgy is a vertical shooter with its own unique graphical design taking inspiration from anime and the look of cel-shaded graphics.

In this unique vertically-scrolling shooter you take the role of a mysterious girl named Karous, who commands a tiny fighter ship and attempts to destroy an evil armada bent on world domination. The game plays as your average vertical-scrolling shooter, in which you must clear several stages by destroying all incoming enemies and surviving their onslaught. A unique addition to Karous, is that you don't collect weapons by power-ups, but instead upgrade each of your basic weapons (gun, sword and shield) depending on their use thanks to a basic experience module, with increased power and features at later levels (multiple shots, bullet reflection, etc.) The game uses cel-shaded polygonal graphics with a distinct black and white look.

Tokita Shouji is seriously injured during a sudden monster attack. Desperate to keep himself alive, he traded vows with Ai, a mysterious girl who could turn her partner into the Armit Cerberus through a process called "Conception". The Armit is a something like an armor, which gives wearer special powers such as speed, sharp claws and attack force. Meet, and fight other Armits and discover the secret behind the odd Kusanagi organization that causes the monster attack that nearly killed you.
