About Ultra0
Ultra0 is a pseudo-3D shooter with visual novel sections. You play as Shirogane, an elite warrior who hunts giant monsters in Nation N, where relentless attacks threaten humanity with extinction. Move to aim at enemies and your character attacks automatically; you can also activate Bombs and Skills with a button press.
Story
The first kaiju appeared in Nation N ten years ago, beginning a long and brutal struggle that has cost countless lives. The remaining girls are now the last line of defense. Shirogane belongs to elite Unit 81, one of the most dangerous active combat zones, and has repeatedly saved her comrades through her combat skill. She heads back to the battlefield to face a new, unknown kaiju. The protagonist changes with each chapter.
Fight and power up
You battle wave after wave of monsters and collect randomly appearing supply items to strengthen your character. If you are lucky, an item's effect may be doubled or tripled.
