Game Paradise 2

Keeps the vertical scrolling mechanics of the original shooter, but uses a light gun to shoot on screen. A scream in two player, but also playable solo. Some special characters including a vampire girl and a flying pig. With new songs and cut scenes produced by famous anime voice actors. Full of nods towards the fan boys and girls with in game references to Space Invaders and having to shoot a CD into a console. Known in Japan as Gunbare Game Tengoku 2.
