Rolling Gunner + Over Power (2021)

Use the Over Power rules included in this package: the rolling gun can intercept bullets, a buster beam destroys incoming fire, and a plasma shield recovers automatically. Positioning the auxiliary gun therefore becomes part of keeping a safe route open while attacking. These are substantial changes from the base game's bomb-based defence, not just a harder difficulty setting. Choose it if you want several active defensive tools together; a separate Switch Over Power download requires the original game.
