Raiden 1, also known by its more complicated name of Raiden IIS Part A, is the prequel to Raiden IIS Part B and is the very first game in the Raiden series. You play the role of a fighter pilot in an old school atari style shooter. Collect weapons and items to power up your ship and avoid taking damage from your enemies. The major difference between Raiden 1 and Raiden X? You get a lifebar. Like all Raiden games, the soundtrack is excellent!
