Overview and Gameplay

A lone starfighter STYX is deployed against the ORN Empire across multiple hostile planetary systems, pushing through dense enemy formations and large-scale boss encounters. The mission structure allows players to select early routes before committing to a linear progression of stages filled with fast-moving projectile combat and large mechanical enemies.

The gameplay focuses on precision movement, weapon swapping, and managing screen pressure as enemy waves intensify. Each stage ends with a boss battle that requires pattern recognition and steady positioning while maintaining constant firepower.
