Guide for Raiden

Raiden (雷電) Raiden Trad is a vertical shoot 'em up videogame released in 1990.

The word "vertical" means that you see your ship from above, and the stage

scrolls vertically from top to bottom. One of Raiden's peculiar notes is that

the horizontal portion of the stage is larger by the actual screen size, and

the player can scroll horizontally for about two screens. Main events occour in

the central area, however.

Raiden is so difficult but extremely beautiful that Seibu eventually released

Raiden 2 and 3; in Raiden 2 you can choose between ships with different

capabilities and Raiden 3 is even more difficult than the first.

Aside the infos above, I have no knowledge of the game's background, though an

alien race or something similar is invading Earth and you have to stop them.
